The inverter host 1 uses an algorithm based on indoor sub-regional temperature control to control the output power of the heater. , individually control the temperature of each heater, in order to achieve the purpose of rapid and uniform temperature in the room. The heating system 3 and the cooling system 2 cannot work at the same time.

It can be seen that the working principle of the present invention is as follows: according to the specific conditions of the house, sub-regions are implemented. The temperature sensor 4 installed around collects the real-time temperature of each area, and transmits it to the inverter host 1 through the diode 5. The built-in inverter host 1 realizes the temperature control algorithm based on indoor sub-regions. First, according to the real-time temperature of each area and the set temperature The difference value controls the frequency conversion of the frequency conversion host 1.

During the heating process, the frequency conversion host 1 controls the output power of the heating element in the heating system 3 .

Among them, the tree-shaped air transmission pipes 2-2 are horizontally buried between the various compartments, so that each area operates independently, and the occupied space is compressed as much as possible. The air outlet panels 2-5 are designed in a honeycomb shape to keep the number of air outlets. While maintaining an aesthetically optimized space.

The invention also discloses an indoor temperature control method, comprising:

Divide the indoor space into a plurality of areas, and install the honeycomb type air outlet 2-1 and the electric heating sheet in each divided area. Among them, the principle of regional segmentation: first, draw a two-dimensional pixel map of the plane according to the density of indoor objects (the color block is dark in the place with high density, and the color is light when the density is small), and n points are averaged on the map based on the actual indoor area (approximately It is one point per 15 square meters), and then implements the region growing block principle with these n points (unmarked pixels near the retrieval point, if their difference is within the specified threshold, they will be merged into the segmentation area), In this way, n regions are roughly divided, and then the shape of these n regions is optimized in detail (the border lines are angular) to achieve an area of approximately 15 square meters for each region. There are roughly 15 to 25 honeycomb-type air outlets 2-1 installed in each area, and the gaps between the air outlets are spliced with honeycomb-type wooden boards of equal size. The placement of the underground heaters is also in accordance with the block principle, and each heater corresponds to the tuyere at the upper honeycomb.

When the current temperature control mode is selected as the cooling mode, obtain the first temperature of all the temperature sensors 4 in each of the regions; control the air output and the air outlet of the honeycomb air outlet 2-1 according to the first temperature The outlet angle of the fan blade.

During the cooling process, after the variable frequency host 1 operates, the temperature sensors 4 on the surrounding walls input the collected temperature data into the host, the insulation layer partitions 2-3 and the air outlet panels 2-5, and the variable frequency host 1 performs the operation according to the indoor average temperature. Once frequency conversion, adjust the output power. Among them, in the frequency conversion process, taking the frequency conversion host of 10HZ ~ 90HZ as an example, during cooling: when the real-time average temperature (T now) / set temperature (T set) >= 1.2, the adjustment frequency is between 70HZ ~ 90HZ; When the average temperature (T present)/set temperature (T setting)>=1.15 and <1.2, the adjustment frequency is 50HZ~70HZ; real-time average temperature (T present)/set temperature (T setting)>=1.1 and <1.15 , the adjustment frequency is between 30HZ and 50HZ; the real-time average temperature (T now)/set temperature (T setting)>=1.05 and <1.1, and the adjustment frequency is between 10HZ and 30HZ. During heating: the algorithm is the same as during cooling, and the heating set temperature (T setting) / real-time average temperature (T current) is brought into the algorithm based on indoor sub-regional temperature control, namely: real-time average temperature (T current) / When the set temperature (T setting)>=1.2, the adjustment frequency is between 70HZ ~ 90HZ; when the real-time average temperature (T current)/set temperature (T setting)>=1.15 and <1.2, the adjustment frequency is 50HZ ~ 70HZ ; Real-time average temperature (T present)/set temperature (T setting)>=1.1 and <1.15, the adjustment frequency is 30HZ ~ 50HZ; real-time average temperature (T present)/set temperature (T setting)>=1.05 and < 1.1, the adjustment frequency is 10HZ ~ 30HZ.

When the air flow output by the host after frequency conversion enters the area between the insulation layer partitions 2-3 and the air outlet panels 2-5, the frequency conversion host 1 simultaneously adjusts the insulation layer partitions according to the real-time transmission of the temperature sensor 4 in each area of the room. The degree of closure of each vent switch in 2-3, the airflow flows along the air pipeline, and the secondary frequency conversion is realized. The closing degree of each vent switch is adjusted according to the ratio of the average temperature of the temperature sensor 4 in each regional space to the set temperature. When the real-time area average temperature (T present)/set temperature (T setting) >= 1.2, adjust the opening angle of the channel between 70 and 90 degrees; the real-time area average temperature (T present)/set temperature (T setting) When >=1.15 and <1.2, the opening angle of the adjustment channel is between 50 and 70 degrees; the real-time area average temperature (T present)/set temperature (T setting) >=1.1 and <1.15, the opening angle of the adjustment channel is at Between 30 and 50 degrees; real-time average temperature (T now) / set temperature (T set) >= 1.05 and < 1.1, and the opening angle of the adjustment channel is between 10 and 30 degrees. The opening angles of the air transmission pipes in each area operate independently and do not interfere with each other.

When the gas passes through the air outlet panel 2-5 through the air transmission duct, the frequency conversion host 1 adjusts the angle of the blades in the honeycomb air outlet 2-1 according to the temperature of each area in the room transmitted in real time by the temperature sensor 4, and controls each honeycomb air outlet 2 -1 air output, so as to implement three frequency conversion.

When the current temperature control mode is selected as the heating mode, the second temperature of all the temperature sensors 4 in each of the regions is obtained; the temperature of the heating sheet is controlled and controlled according to the first temperature. In the heating process, according to the area divided by the secondary machine panel 2-4, install the electric heating piece under the floor, the electric heating piece is connected to the nearby temperature sensor 4, and the temperature data transmitted by the temperature sensor 4 is compared with the set temperature, Constantly adjust the output power.

The present invention is divided into refrigerating and heating parts, the refrigerating system 2 is placed on the roof, and adopts a full-covering structure—a honeycomb structure. While covering a wide range, it can adapt to more shapes of roof space. Since the air outlet is all over the upper space, several strands of cold air are emitted along the air outlet at the same time and then sink rapidly due to the weight of the gas itself. Because of the unique regional block design of the present invention, the cooling is globalized and time-effective. The heating system is placed under the floor of the room, and the electric heating sheet is used as the heating source. Through heating, the air in the special compartment and the upper floor area thermally expands. When the hot air flows and rises, the temperature brought by the electric heating sheet makes the hot air below continue to expand. Rise until the set room temperature requirement is reached. Ensure human comfort and efficiency at the same time. The refrigeration system 2 is on the top, and the heating system 3 is on the bottom, making full use of the aerodynamic principle, which greatly reduces the time to reach the set temperature.
