Detailed ways

In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

Please refer to Figures 1-3. This embodiment provides an energy-saving dehumidification heat pump suitable for a swimming pool 8. It should be explained in advance that the energy-saving dehumidification heat pump of this scheme is suitable for indoor swimming pools 8. The dehumidification heat pump of this scheme includes, from left to right, a fresh air device 1 and an air supply device 2 that are interconnected. The fresh air device 1 is used to absorb and replenish the outside air into the fresh air device 1, and the air supply device 2 is connected to the fresh air device 1 to transmit the outside air in the fresh air device 1 to the air supply device 2, and the air supply device 2 then transmits the outside air to the indoor swimming pool 8.

The fresh air device 1 is provided with a fresh air duct 101, and both ends of the fresh air duct 101 are respectively connected to the fresh air device 1 and the external environment. The fresh air device 1 transmits the external air to the fresh air device 1 through the fresh air duct 101; the air supply device 2 is provided with an air supply duct 201, one end of the air supply duct 201 is connected to the air supply device 2, and the other end of the air supply duct 201 is located at the top of the swimming pool 8. The air supply device 2 transmits the external air from the fresh air device 1 to the air of the swimming pool 8 through the air supply duct 201.

It also includes a control module 3, a fresh air valve 102 and a compressor 4. The compressor 4 is connected and arranged between the fresh air device 1 and the air supply device 2. The fresh air valve 102 is arranged at the junction of the fresh air duct 101 and the external environment. The control module 3 is communicated with the compressor 4 and the fresh air valve 102 respectively. It is worth noting that the control module 3 of the present scheme can control the opening and closing degree of the valve mouth of the fresh air valve 102, thereby controlling the amount of external air absorbed by the fresh air duct 101. The purpose of setting the compressor 4 is to provide power to the external air transmitted by the fresh air device 1, so that this part of the external air has power to flow into the swimming pool 8 air later. In addition, the present scheme also has a heating device between the fresh air device 1 and the air supply device 2. The heating device is interconnected with the fresh air device 1 and the air supply device 2 respectively, and the heating device is interconnected with the control module 3 to heat the air that subsequently flows into the heating device.

It also includes a first temperature and humidity sensor 5 and a temperature and humidity sensor group 6. The first temperature and humidity sensor 5 and the temperature and humidity sensor group 6 are both connected to the control module 3 in communication. The first temperature and humidity sensor 5 is arranged at the fresh air valve 102 to detect the temperature and humidity of the outside air; the temperature and humidity sensor group 6 is arranged on the top of the swimming pool 8 to detect the temperature and humidity of the air in the swimming pool 8. The data detected by the first temperature and humidity sensor 5 and the temperature and humidity sensor group 6 are transmitted to the control module 3, and then the control module 3 processes the detection data according to the preset algorithm and program, and finally the control module 3 controls the fresh air valve 102 and the compressor according to the processed data. 4 performs corresponding actions. On the one hand, the dehumidification heat pump of the present solution can automatically control the start-up and operation of the compressor 4, so that the swimming pool 8 can turn off the compressor 4 when the compressor 4 is not needed to operate, thereby achieving the purpose of saving energy by reducing the operating time of the compressor 4; on the other hand, the present solution is provided with a control module 3, and the control module 3 calculates and judges the detected data through a preset algorithm and program, and finally controls the fresh air valve 102 and the compressor 4 to perform corresponding actions according to the processed data, thereby realizing the self-regulation of the dehumidification heat pump, and replacing the link of the traditional dehumidification heat pump that requires manual operation.

The dehumidification heat pump of this scheme detects the outdoor temperature conditions by itself, confirms whether the outdoor air has utilization value through internal calculations, and adjusts and controls the fresh air valve 102 through the control module 3, so as to achieve effective utilization of outside air, reduce the operating time of the compressor 4, and reduce energy consumption throughout the year. At the same time, since the dehumidification heat pump of this scheme adjusts the valve opening and closing degree of the fresh air valve 102 and the operating status of the compressor 4 by itself through detection data, it avoids non-professional customers from operating the fresh air valve 102, reduces electricity bill losses caused by customers' misoperation, and solves the problems of existing dehumidification heat pumps suitable for swimming venues, such as high power consumption, no energy saving, and the need for manual operation and adjustment, and the inability to adjust by itself, which wastes labor costs.

Next, the control logic of the control module 3 of this scheme is described in detail: first, the first temperature and humidity sensor 5 is used to detect the temperature and humidity of the outside air, and the detected temperature is recorded as X1, the detected humidity is recorded as Y1, and then the data is uploaded to the control module 3; the temperature and humidity sensor group 6 is used to detect the temperature and humidity of the air in the swimming pool 8, and the detected temperature is recorded as X2, the detected humidity is recorded as Y2, and the data is uploaded to the control module 3, and then the control module 3 obtains the central temperature X3 and central humidity Y3 between the outside air and the air in the swimming pool 8 according to the data detected by the first temperature and humidity sensor 5 and the temperature and humidity sensor group 6. Then, a coordinate axis is established, the horizontal axis of which is temperature and the vertical axis is humidity. Coordinates (X1, Y1), (X2, Y2) and (X3, Y3) are placed in the coordinate axis, and the three coordinates are connected. Since coordinate (X3, Y3) is the midpoint of the line connecting coordinates (X1, Y1) and coordinates (X2, Y2), the three coordinates actually appear as a straight line. A standard temperature point X and a standard humidity point Y are preset in the control module 3 in advance, and the coordinates are imported into the coordinate axis. At this time, the points with standard temperature and humidity are respectively connected with coordinates (X1, Y1), (X2, Y2) and (X3, Y3), and are recorded as Z1, Z2 and Z3. Here, it is explained that Z1 represents the distance from the preset standard temperature and humidity to the temperature and humidity of the outside air; Z2 represents the distance from the preset standard temperature and humidity to the temperature and humidity of the air of the swimming pool 8; Z3 represents the distance from the preset standard temperature and humidity to the central temperature and humidity between the outside air and the air of the swimming pool 8. It is worth noting that Z1, Z2 and Z3 represent different operations performed by the control module 3 on the fresh air valve 102 and the compressor 4. After obtaining the values of Z1, Z2 and Z3, the control module 3 needs to determine the values of Z1, Z2 and Z3, take out the minimum value, and assign the value to a. Then the control module 3 uses the value calculated by a to instruct the fresh air valve 102 to rotate to a preset angle and instruct the working state of the compressor 4; wherein, X3 = (X1 + X2) / 2, Y3 = (Y1 + Y2) / 2;

When a=Z1, it means that the temperature and humidity of the outside air are closest to the preset standard temperature and humidity. At this time, the control module 3 controls the valve of the fresh air valve 102 to be fully opened, and the compressor 4 is turned off, and the indoor temperature and humidity are adjusted completely by the fresh air;

When a=Z2, it means that the temperature and humidity of the air in the swimming pool 8 are closest to the preset standard temperature and humidity. At this time, the control module 3 controls the valve of the fresh air valve 102 to be fully closed, and the compressor 4 is fully opened, so that the indoor temperature and humidity are adjusted by fully utilizing the work of the compressor 4;

When a=Z3, the control module 3 controls the fresh air valve 102 to be half-open, turns on part of the compressor 4, and introduces part of the fresh air to assist in adjusting the indoor temperature and humidity, thereby reducing part of the energy consumption.

Further, after the control module 3 controls the fresh air valve 102 and the compressor 4 to perform corresponding actions according to the processed data, the absorbed air will be transmitted to the air supply device 2, and then transmitted to the air supply pipe 201 through the air supply device 2. Finally, the absorbed air will be transmitted to the swimming pool 8 through the air supply pipe 201. However, there will be a problem at this time. If the air in the air supply device 2 flows from one point of the air supply pipe 201 to the swimming pool 8, it is impossible to ensure that the temperature and humidity of each place in the swimming pool 8 are consistent. Based on this, the present solution is provided with a plurality of through holes at one end of the air supply pipe 201 located at the top of the swimming pool 8. The air supply device 2 includes a plurality of Air supply valve 202, a plurality of air supply valves 202 are matched with a plurality of through holes in a one-to-one correspondence, any air supply valve 202 is arranged in a corresponding through hole, the air supply valve 202 is communicatively connected with the control module 3, and this scheme arranges a plurality of air supply valves 202 at one end of the air supply pipe 201 located at the top of the swimming pool 8, and the absorbed air flows into the swimming pool 8 room through the air supply valve 202 arranged on the side wall of the air supply pipe 201, so that the air temperature and humidity at the same height in the swimming pool 8 are consistent, which solves the problem that if the air in the air supply device 2 flows from one place of the air supply pipe 201 to the swimming pool 8 room, it is impossible to ensure that the temperature and humidity at various places in the swimming pool 8 are consistent.

Furthermore, the above scheme is provided with a plurality of air supply valves 202, and the absorbed air flows into the swimming pool 8 through the air supply valves 202 provided on the side walls of the air supply pipe 201, so that the air temperature and humidity at the same height in the swimming pool 8 are consistent. However, such a setting cannot guarantee that the air temperature and humidity at different heights in the swimming pool 8 are consistent. Based on this, the temperature and humidity sensor group 6 of this scheme includes a plurality of temperature and humidity sensors, and the plurality of temperature and humidity sensors are arranged at equal intervals on the top of the swimming pool 8 along a direction perpendicular to the surface of the swimming pool 8. The plurality of temperature and humidity sensors are connected to the control module 3 for communication. With such a setting, the control module 3 of this scheme determines the actual temperature and humidity at different heights in the swimming pool 8 through the data detected by the temperature and humidity sensors set at different heights. Based on this, the control module 3 controls the opening and closing degree of the valve port of the air supply valve 202 to adjust the temperature and humidity at different heights in the swimming pool 8 to be consistent. The specific method is as follows: the temperature and humidity sensor group 6 is used to detect the temperature points W at different heights of the air in the swimming pool 8, W=W1, W2...Wn (n is a natural number), and the humidity points S, S=S1, S2...Sn (n is a natural number), and upload the data to the control module 3 ; Starting from the temperature and humidity sensor with the lowest setting height, the temperature and humidity data detected by the temperature and humidity sensor at this height is recorded as Q1=(W1, S1), and the data is uploaded to the control module 3. At this time, the control module 3 uses the preset standard temperature point as X and the standard humidity point as Y; and the preset temperature and humidity deviations are X deviation and Y deviation respectively. Then the control module 3 will judge the temperature and humidity data detected by the temperature and humidity sensor with the lowest setting height. If the value of Q1=(W1, S1) meets the judgment condition: X+X deviation ≥W1 ≥X-X deviation and Y+Y deviation ≥S1 ≥Y-Y deviation, then it means that the temperature and humidity at this height meet the temperature and humidity requirements of the swimming pool 8 room, and there is no need to supplement the temperature and humidity at this height; if the value of Q1=(W1, S1) does not meet the judgment condition: X+X deviation ≥W1≥X-X deviation and Y+Y deviation ≥S1≥Y-Y deviation, then it means that the temperature and humidity at this height do not meet the temperature and humidity requirements of the swimming pool 8 room, and the control module 3 needs to control the air supply valve 202 to supplement the temperature and humidity at this height until the temperature and humidity data detected by the temperature and humidity sensor at this height meet the temperature and humidity requirements of the swimming pool 8 room again.

Then set the second-to-last temperature and humidity sensor to repeat the above operation until all temperature and humidity sensors have repeated the above operation. At this time, the temperature and humidity at various heights in the swimming pool 8 can be kept consistent.

It is worth noting that the air pressure inside the air supply pipe 201 of the present solution is always kept consistent. On this basis, in order to ensure that the air supply valve 202 can transmit the treated air to the swimming pool 8 rooms at different heights, the control module 3 controls the opening and closing degree of the valve port of the air supply valve 202, so that the opening and closing degree of the valve port of the air supply valve 202 increases from bottom to top along the setting direction of the temperature and humidity sensor. This is because the internal air pressure of the air supply pipe 201 of the present solution is always kept consistent. The smaller the valve port of the air supply valve 202, the greater the initial velocity of the air coming out of the valve port of the air supply valve 202, so that the treated air can be sprayed out at a farther distance from the air supply valve 202.

Furthermore, when the temperature and humidity of the outside air do not meet the standard temperature and humidity in the swimming pool 8, it is necessary to absorb the air in the swimming pool 8, and release the treated air in the swimming pool 8 again after processing. Based on this, the present scheme also includes a return air device 7, and the return air device 7 is connected to the fresh air device 1. The return air device 7 is provided with a return air duct 701. The return air duct 701 is provided with a plurality of air holes along its axial direction. The return air device 7 also includes a plurality of return air valves 702. The plurality of return air valves 702 are matched with the plurality of air holes in a one-to-one manner. Any return air valve 702 is arranged in a corresponding air hole. The return air valve 702 is communicatively connected with the control module 3. Here, it is explained that the present scheme The axial direction of the return air duct 701 is parallel to the setting direction of several temperature and humidity sensors. In this scheme, a return air device 7 is provided. When the temperature and humidity sensor detects that the temperature and humidity in the swimming pool 8 room do not meet the standard temperature and humidity in the swimming pool 8 room, the control module 3 controls the return air valve 702 to open its valve port, and the control module 3 starts the compressor 4, so that there is a pressure difference between the air pressure of the return air device 7 and the air pressure in the swimming pool 8 room. The air in the swimming pool 8 room will enter the return air device 7 through the return air valve 702 due to the existence of the pressure difference, and then go through a series of treatments on the inhaled air, and finally pass through the air supply device 2 again to release the treated air into the swimming pool 8 room.

It should be noted that the lowest setting height of the temperature and humidity sensor in this scheme is 2m above the surface of the swimming pool 8. This setting is because when people swim in the swimming pool 8, it will cause turbulence in the air in this area of the swimming pool 8, which will lead to inaccurate actual measurement of the temperature in this area. After the air in the swimming pool 8 leaves the turbulent area, the temperature and humidity of the swimming pool 8 will tend to be stable again. Therefore, measuring the temperature and humidity of the air at this height will ensure stability. Generally speaking, the temperature and humidity of the air above 2m from the surface of the swimming pool 8 will tend to be stable. Therefore, in this scheme, the lowest setting height of the temperature and humidity sensor is 2m above the surface of the swimming pool 8.

Generally speaking, the closer the air in the swimming pool 8 is to the swimming pool 8, the higher the humidity is. At this time, the humidity at this height does not meet the standard humidity range, but the temperature meets the standard temperature and humidity range; the farther away from the swimming pool 8, the humidity meets the standard temperature and humidity range, but the temperature will be lower and does not meet the standard temperature range; therefore, the air in the swimming pool 8, which is close to the swimming pool 8, needs to absorb the swimming pool 8 air at this height, and after the excess humidity of the swimming pool 8 air at this height is processed, the humidity of the swimming pool 8 air at this height meets the standard temperature and humidity range again, and then after being heated by the heating equipment, the processed air is released to the swimming pool 8 air at the top through the air supply equipment 2, so that the temperature of the swimming pool 8 air at the top increases, and then the temperature of the air far away from the swimming pool 8 meets the standard temperature and humidity range again. Based on this, the setting height of the several air holes on the return air duct 701 of the present scheme is located between the two temperature and humidity sensors with the lowest setting height.

Furthermore, when the control module 3 of the present solution controls the valve port of the air supply valve 202 to open and absorbs the air of the swimming pool 8 at that height, in order to avoid absorbing too much air of the indoor swimming pool 8 and causing the air in the indoor swimming pool 8 to become thin, while the control module 3 controls the valve port of the air supply valve 202 to open, the control module 3 of the present solution also controls the valve port of the return air valve 702 to open, and the opening and closing degree of the valve port of the air supply valve 202 is consistent with the opening and closing degree of the valve port of the return air valve 702. Such an arrangement ensures that the total amount of air in the indoor swimming pool 8 remains unchanged and is maintained in a balanced state.

Furthermore, the bottom of the swimming pool 8 is tilted from left to right toward the bottom, and the swimming pool 8 is divided into a shallow water area 801, a middle water area 802, and a deep water area 803 according to its depth, and the return air duct 701 is arranged at the top of the right end of the swimming pool 8. The surface lengths of the shallow water area 801, the middle water area 802, and the deep water area 803 are consistent. In order to meet the needs of people of different heights, the existing swimming pool 8 is tilted from left to right toward the bottom of the swimming pool 8. Such a setting makes the actual water volume of the deep water area 803 greater than the water volume of the middle water area 802 and the water volume of the shallow water area 801. Based on the existing setting of the swimming pool 8, it can be inferred that in the same Under the temperature, the evaporation rate of the deep water area 803 is greater than the evaporation rate of the middle water area 802, which is greater than the evaporation rate of the shallow water area 801, so that the air temperature and humidity in the deep water area 803 is greater than the air temperature and humidity in the middle water area 802, which is greater than the air temperature and humidity in the shallow water area 801. In the swimming pool 8, swimmers often swim back and forth from the shallow water area 801 to the deep water area 803. If the difference in air temperature and humidity between the shallow water area 801 and the deep water area 803 is large, it is easy to cause the risk of spasm when the swimmer is swimming. Therefore, it is urgent to solve the problem of the large difference in air temperature and humidity between the shallow water area 801 and the deep water area 803.

In order to solve the above problems, the air supply duct 201 of the present solution includes, from left to right, a first air duct 9, a second air duct 10 and a third air duct 11 which are coaxially connected in sequence. The other end of the third air duct 11 is connected to the air supply device 2. The three air ducts are matched one by one with the three water areas of the swimming pool 8. The first air duct 9 is correspondingly arranged at the top of the shallow water area 801, the second air duct 10 is correspondingly arranged at the top of the middle water area 802, and the third air duct 11 is correspondingly arranged at the top of the deep water area 803. Any air duct is arranged directly above the corresponding water area of the swimming pool 8. The setting density of the air supply valve 202 of the third air duct 11 is less than the setting density of the air supply valve 202 of the second air duct 10, and the setting density of the air supply valve 202 of the second air duct 10 is less than the setting density of the air supply valve 202 of the first air duct 9. The purpose of such setting is that since the air supply valve 202 of the third air duct 11 is located in the deep water area 801, the air supply valve 202 of the second air duct 10 is located in the deep water area 802. 03 is greater than the humidity of the middle water area 802, which is greater than the humidity of the shallow water area 801. Therefore, when the treated air flows out from the air supply valve 202 of the air supply pipe 201, it is necessary to ensure that the air temperatures flowing out of the third air duct 11, the second air duct 10 and the first air duct 9 are the same within a unit time, but the humidity of the outflowing air needs to be increased sequentially. Based on this, in this scheme, the setting density of the air supply valve 202 of the third air duct 11 is less than the setting density of the air supply valve 202 of the second air duct 10, and the setting density of the air supply valve 202 of the second air duct 10 is less than the setting density of the air supply valve 202 of the first air duct 9, which in turn ensures that the temperature and humidity of the air in the final swimming pool 8 are consistent everywhere, and solves the problem that the temperature and humidity of the air from the shallow water area 801 to the deep water area 803 are quite different, which easily leads to the risk of spasm for swimmers when swimming.
