Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the attached figure 1, a low-temperature fresh air dehumidifier control device comprises an indoor unit and an outdoor unit, wherein the indoor unit is provided with a fresh air inlet 1, a return air inlet 2, an air outlet 3 and an air outlet 4, the device comprises a compressor 5, a four-way valve 6, a condenser, an electronic expansion valve 8, a flash evaporator 9, a battery valve 10 and a throttle valve 11, one end of the battery valve 10 is connected with an air supplementing port of the compressor 5, the other end of the battery valve 10 is connected with an evaporation port of the flash evaporator 9, an exhaust port of the compressor is connected with one port of the four-way valve, one port of the four-way valve is connected with the condenser, the condenser is connected with the electronic expansion valve, the electronic expansion valve 8 is connected with the throttle valve 11 through the flash evaporator 9 and a filter 12 through pipelines, the throttle valve is connected with the indoor unit through a stop valve, one port, the compressor, the condenser, the electronic expansion valve, the flash evaporator, the battery valve and the throttle valve are all connected with the controller. The indoor unit is further provided with a gas sensor and a coil temperature sensor (not shown in the figure, the installation position is not particularly fixed), and the gas sensor and the coil temperature sensor are respectively connected with the controller. And detecting the corresponding temperature and air quality in real time by using a coil temperature sensor and a gas sensor.
The fresh air inlet 1 is internally provided with a fresh air valve F2, the return air inlet 2 is internally provided with a return air valve F1, the air outlet 3 is internally provided with an exhaust air valve F3, the air outlet 4 is internally provided with an air outlet valve F4, the air outlet 4 is provided with an air outlet fan CF, the air outlet 3 is provided with an air outlet fan PF, and the air outlet fan, the fresh air valve, the return air valve, the air outlet valve and the air outlet valve are all connected with the controller. The fans all adopt brushless direct current motors as driving motors.
The battery valve receives a control instruction of the controller and is opened or closed according to the control instruction. The enthalpy increasing assembly is formed by the battery valve and the flash evaporator together, so that the compressor still has normal air return amount under the condition of low outdoor environment temperature, the normal operation frequency of the compressor is guaranteed, the problem of reduction of the power of the compressor is not easy to occur, and the dehumidification and refrigeration effect can be guaranteed.
The flash evaporator separates low-temperature and low-pressure gaseous refrigerant at low ambient temperature, and the low-temperature and low-pressure gaseous refrigerant enters the compressor through the battery valve; the control system determines the target opening degree of the electronic expansion valve under the condition of program setting, and specifically comprises the following steps: during dehumidification refrigeration cycle, the controller sends out an instruction to close the battery valve, determine the initial set opening of the electronic expansion valve according to the running frequency of the compressor, the temperature of outdoor environment, the temperature of outdoor coil and the temperature of indoor environment, and then run according to a set program; or, during heating circulation, the control system sends out instructions to open the battery valve, operate the throttle valve, determine the initial set opening of the electronic expansion valve according to the running frequency Fr of the compressor, the temperature of the outdoor environment, the temperature of the outdoor coil and the temperature of the indoor environment, and then run according to the set program.
