Description

Intelligent cold-warm type floor embedded type convector

Technical Field

The invention relates to the technical field of building glass curtain walls and cooling and heating equipment, in particular to an intelligent cooling and heating type floor embedded type convection device.

Background

The building glass curtain wall is a beautiful and novel building wall decorating method. However, the conventional radiator cannot meet the effect of counteracting indoor cold and hot loads of the glass curtain wall building. With the continuous innovation and development of technology, floor convectors, which are terminal devices of a central air conditioning system, are installed on a floor for blowing cool air or hot air into a room. The integrated intelligent indoor temperature difference load changing device has the advantages that the integrated intelligent indoor temperature difference load changing device integrates attractiveness and practicability, and the solving capability of indoor temperature difference load change of a glass curtain wall building can be greatly improved, so that the floor embedded type convector is widely used.

The patent CN 205747157U discloses a cooling and heating type floor embedded type convection device with a fresh air function, which comprises: the air inlet and outlet grille is arranged on the upper portion of the shell, an air convection cavity is formed in the shell, a partition plate is connected in the shell, the air convection cavity is divided into an upper air convection cavity and a lower air convection cavity, an air outlet is formed in the partition plate, the heat exchanger is located in the upper air convection cavity, and an air inlet is formed in the shell around the lower air convection cavity. The beneficial effects are as follows: the air curtain is formed by a fresh air mode, a secondary air mode or a fresh air and secondary air mixed mode, so that indoor cold (heat) load is eliminated, indoor and outdoor cold and heat exchange is effectively shielded, and indoor fresh air requirements are met. However, the prior art floor convectors also have the following disadvantages:

first: the floor convector in the prior art is of an embedded structure, so that the floor convector is lack of supplement of a fresh air system and corresponding structural support. The corresponding problems are that the inner circulation and the air quality reduction of the glass curtain wall building are carried out under the indoor closed environment, so that the people feel clumsy, and the living or working comfort of indoor people is influenced. In the above floor convector technical scheme, the introduced fresh air is adopted for supplementing, and although the air quality can be improved to a certain extent, the effect is general. And the structure is comparatively complicated, needs glass curtain wall reservation position intercommunication external world, and space wholeness design is unreasonable enough, is inconvenient for the installation.

In order to ensure the convenience of integral embedded installation, the floor embedded type convector is combined with a building into a whole with higher precision, fresh air is provided for the indoor closed environment of the glass curtain wall, discomfort of indoor staff is relieved, air quality is improved, and a mode of introducing negative oxygen ions can be adopted. Negative oxygen ions are also called negative ions, and are very beneficial to human health. Negative ions are the general term for negatively charged ions in air, and are conventionally referred to as negative oxygen ions because negatively charged oxygen occupies the greatest specific weight. World health organization specifies: the standard concentration of negative oxygen ions in the fresh air is more than 1500/cm < 3 >. The ecological negative ions can actively strike and capture small particle dust positively charged in the air to enable the small particle dust to be condensed and precipitated, so that particle pollutants in the air are effectively removed, and the purifying effect of the ecological negative ions on the air is achieved by combining the negative ions with positively charged particles such as bacteria, dust, smoke and the like in the air and agglomerating and falling so as to achieve the aim of air purification.

When the concentration of negative ions in indoor air reaches 2 ten thousand per cubic centimeter, the amount of fly ash in the air can be reduced by more than 98 percent. The effect on the particulate matters PM2.5 which can enter the lung is excellent. Therefore, in the air containing the high concentration of the negative ions with small particle diameter, dust, bacteria, viruses, etc. with the largest harm of less than 1 micrometer in PM2.5 are almost zero.

Second,: the air inlet and outlet grille is used as a 'gate' of the floor embedded convector, and is often contacted with other heavier equipment in a glass curtain wall building room, and the bearing capacity of the air inlet and outlet grille is insufficient, so that the air inlet and outlet grille is often damaged. In addition, the floor embedded type convector in the prior art is directly provided with the air inlet and outlet grille above the cross-flow fan and the radiator, and once the air inlet and outlet grille is damaged, the cross-flow fan and the radiator are directly damaged due to extrusion, so that the maintenance cost is high. Furthermore, the cross-flow fan, the radiator and the air inlet and outlet grids lack a filtering and shielding structure, so that dust and sundries fall into the air inlet and outlet grids easily without using the convector for a long time, and the operation safety of equipment is affected.

Third,: reflected by users in the northern market, the water pressure of the radiator is unstable, so that the normal use of the radiator is limited to play a role, and the use effect of the floor embedded type convection device is greatly reduced. And after the radiator is installed, the air tightness test is carried out, the pressure stopping time is 10 minutes under the preset test pressure of 0.4Mpa-0.6Mpa, and the pressure drop is not more than 0.05 Mpa. Whereas prior art floor embedded convectors lack regulation of radiator voltage regulation.

Thus, by expanding to both sides, the radiation area of the negative oxygen ion "fresh air" flow is increased.

When the indoor air quality detection parameter is higher than a preset value, namely the indoor air pollution is serious, the quality is in a worry, and then negative oxygen ions generated by the accelerating releaser are introduced into the indoor and air is purified until the indoor air quality detection parameter is restored to the preset value, so that the indoor air quality is intelligently detected, the fresh air flow of the negative oxygen ions is introduced, the indoor air quality of the glass curtain wall building is greatly improved, meanwhile, the comfort level and the refreshing feeling of staff are also improved, and the practicability of the convector is greatly improved.

The water pressure detector 71 is arranged in the water inlet pipe 31 and is positioned in the equipment control cavity 12; the hydraulic pressure monitoring device is used for monitoring the hydraulic pressure in real time. One end of the pressure stabilizing tube 72 is connected with the water inlet tube 31, and the other end is connected with the pressure reducing tube 73 and the pressure increasing tube 74 through a three-way joint; the voltage stabilizing tube is perpendicular to the water inlet tube. The other end of the pressure reducing pipe 73 leads to the liquid storage cavity 47, a first electromagnetic control valve 76 is further arranged on the pressure reducing pipe 73, and a one-way valve is arranged on the pressure reducing pipe 73, so that when the first electromagnetic control valve 76 is opened, water flow can only flow to the liquid storage cavity 47 along the pressure reducing pipe 73 through the water inlet pipe 31.

The other end of the pressurizing pipe 74 is connected with the micro liquid pump 75, the pressurizing pipe 74 is further provided with a second electromagnetic control valve 77, and the pressurizing pipe 74 is also provided with a one-way valve, so that when the second electromagnetic control valve 77 is opened, water flow can only flow and pressure from the liquid storage cavity 47 to the water inlet pipe 31 along the pressurizing pipe 74. While the first solenoid control valve 76 and the second solenoid control valve 77 are guaranteed to operate at different times. The miniature liquid pump 75 is fixedly arranged in the liquid storage cavity 47; and the water pressure detector 71 detects the water pressure value of the water inlet pipe in real time, and transmits an execution command through the controller 462, thereby finally completing the water pressure adjustment to a preset interval value. A liquid level sensor 49 is further disposed in the liquid storage chamber 47, for monitoring the liquid storage in the liquid storage chamber 47, and preventing too little or too much phenomenon.

The purpose of this arrangement is to intelligently adjust the water pressure entering the radiator 3 so that the water pressure detector 71 detects the water pressure value of the inlet pipe in real time and transmits an execution command through the controller 462. The controller 462 also includes a hydraulic pressure signal unit and a data processing unit. The water pressure signal unit is used for receiving a detection signal of the water pressure detector on the water pressure change state of the water inlet pipe, and particularly a pressure index. The data processing unit is used for receiving the data parameters from the water pressure signal unit, comparing and judging the data parameters with preset values, sending pressure reducing and pressurizing signals, further opening the first electromagnetic control valve, and draining the liquid storage cavity through the pressure reducing pipe to achieve the effects of diversion and partial pressure. The second electromagnetic control valve and the liquid pump are started to realize the speed-increasing and pressure-increasing adjustment of the fluid from the liquid storage cavity and the pressure-increasing pipe to the water inlet pipe, and finally the water pressure and the pressure of the water inlet pipe are adjusted to a preset reasonable interval; the safety of the work of the radiator is ensured, the use efficiency of the cold-warm type convector is improved, and the temperature difference load change in the glass curtain wall building room is effectively solved. Furthermore, a filter element can be arranged in the pressure reducing pipe to filter water quality, so that the normal operation of the ion purifying mechanism in the liquid storage cavity is further ensured.

An intelligent cooling and heating type floor embedded type convector has the working principle that:

firstly, the staff fixedly installs components and parts such as the cross-flow fan 2, the radiator 3 and the like on the shell 1, and then the filter plate frame 63 is matched with the fastening groove 611 and the clamping rod 621 and the clamping groove through the inserted link 62, so that the filter plate frame 63 and the shell 1 are stably installed, the purpose of protecting the structure such as the cross-flow fan 2 is achieved, and the keel supporting effect is enhanced. Meanwhile, the filter elements 64 are placed in the keel units 635, so that not only is the filtering effect achieved, but also the dustproof effect is achieved. In the initial state, a small amount of water is filled in the liquid storage cavity 47, and the water reaches the preset low value of the liquid level sensor 49, so that the ion generation of the ion generator is facilitated; meanwhile, the blower 463 is in a normally closed state.

And then the floor embedded type convector is integrally placed in a reserved position of the glass curtain wall building indoor design, the side of the convector radiator 3 is guaranteed to be close to the glass curtain wall, the integral integrity of the convector is further guaranteed, and the purposes of time and labor saving are achieved for embedded installation. And the water source of the radiator 3, the whole power source of the convector, central air conditioning equipment and the like are connected in the next step, so that the floor embedded convector starts to work normally.

The cross flow fan 2 and the radiator 3 of the floor embedded type convection device are started, the cross flow fan 2 starts to enter air through the air inlet part and continuously blows air towards the direction of the flow guide plate 45, and the filter element 64 above the cross flow fan filters indoor initial air. Meanwhile, the ion generator 42 in the liquid storage cavity 47 works to continuously generate electric ions, so that under the action of the ion converter 43, high-kinetic-energy ions are generated through friction and irregular movement, and then released through the releaser 44, the clustered high-kinetic-energy ions can be quickly combined with oxygen components in the air to form negative oxygen ion airflow; the air flow is directed rearward and upward along the guide chamber 48 in the guide plate 45.

And then under the effect of the drainage plate 14 above the radiator 3, keep the lower extreme of base plate 141 and the upper end parallel and level of guide plate 45, the inclination of base plate 141 is greater than guide plate 45, so, the drainage of being convenient for blows the negative oxygen ion air current to indoor space along glass curtain wall, increases the stroke of air current transmission. The spreading plates 142 distributed on the left are inclined to the left, and the spreading plates 142 distributed on the right are inclined to the right. Thus, by expanding to the left and right sides, the radiation area of the negative oxygen ion "fresh air" flow is increased.

The convector monitors and purifies and adjusts the indoor air environment of the glass curtain wall building. The air quality detector 461 monitors the indoor air environment of the glass curtain wall building in real time, and when the indoor air quality detection parameter is higher than a preset value, namely the pollution index is higher, the indoor air pollution is more serious, and the quality is worry. The controller 462 receives the air quality detector 461 and monitors an indoor ambient air quality signal parameter, which may be a pollution index in particular. Because staff initially set the reasonable interval of air quality in the glass curtain wall building. Specifically, the pollution index preset interval is 0-120.

Then comparing the real-time air parameter value with a preset index interval, and when the pollution index is higher than 120, feeding back an execution command signal to the fan 463 to accelerate the introduction of negative oxygen ion airflow into the room and accelerate the air purification of the indoor environment; until the indoor air quality detection parameter is restored to a preset value. Thus, the intelligent detection of indoor air quality and the introduction of fresh negative oxygen ion air flow not only greatly improve the indoor air quality of the glass curtain wall building, but also improve the comfort level and the refreshing feeling of staff.

The convector also starts to intelligently regulate the water pressure entering the radiator 3, so that the water pressure detector 71 detects the water pressure value of the water inlet pipe 31 in real time and transmits an execution command through the controller 462. The controller 462 receives a detection signal of the water pressure change state of the water inlet pipe 31, specifically, a pressure index, from the water pressure detector 71. And through receiving the data parameter from the water pressure signal, comparing with the preset value, then sending the decompression and pressurization signals, further through opening the first electromagnetic control valve 76, the water flow in the water inlet pipe 31 can be led to the liquid storage cavity 47 through the decompression pipe 73, and the shunting and partial pressure effect is completed. Or by opening the second electromagnetic control valve 77 and the liquid pump 75, the fluid speed-increasing and pressure-increasing adjustment from the liquid storage cavity 47 and the pressure-increasing pipe 74 to the water inlet pipe 31 is realized, and finally the water pressure of the water inlet pipe 31 is adjusted to a preset interval, so that the water pressure balance is ensured. Further ensures the working safety of the radiator 3 and increases the use efficiency of the cold-warm type convector.
