an evaporation plate 503 is arranged in the evaporator, a thermal compensation plate of the thermal compensation device and the evaporation plate of the evaporator are arranged in the evaporator in parallel, and the thermal compensation plate is arranged on one side, close to the return air outlet, of the evaporation plate.
A first humidity sensor 14 is arranged at the return air inlet, and a second humidity sensor 15 is arranged at the air outlet;

The air supply device also comprises a humidifier 16, and the tail end of the humidifier is communicated with an air inlet of the air supply device;
the humidifier is electrically connected with the controller. In this embodiment, the humidifier generates water vapor by using an electric heating method, and certainly, the humidifier can also generate water vapor by using methods such as ultrasound, but in actual use, particularly when the humidifier is used in a production workshop, the electric heating is a more reliable method.
The compressor unit comprises at least one compressor unit. In this embodiment, the compressor unit includes two compressor units.
An oil separator 17 is provided between the compressor unit and the condenser.
A first pressure gauge 18 is arranged between the first electric control valve and the condenser, and a second pressure gauge 19 is arranged between the evaporator and the compressor unit.
The throttling device is an electronic expansion valve.
A drying filter 20 is also arranged between the throttling device and the reservoir.
And a one-way valve 21 is arranged on the liquid outlet pipe of the thermal compensation device. In this embodiment, an intake pressure sensor 22 and an exhaust pressure sensor 23 are respectively disposed at two ends of a loop of the compressor unit.
The first electric control valve is an electromagnetic valve, and the second electric control valve is an electric control valve with flow monitoring and control functions.
The working principle is as follows: the return air is cooled after passing through the evaporator, the moisture in the air is condensed, and the relative humidity of the air is reduced after the air is heated by the thermal compensation device. When the second humidity sensor detects that the air humidity is lower than the set value, the humidifier can be started by the controller to perform humidification operation.
When temperature compensation is needed, the controller closes the second electric control valve or reduces the flow in the second electric control valve, opens the first electric control valve, and enables medium-temperature high-pressure refrigerants (high-temperature high-pressure refrigerants sent out from the compressor unit are changed into medium-temperature high-pressure refrigerants through the condenser) to flow through the heat compensation plate, so that air-conditioning return air passes through the heat compensation plate after passing through the evaporator (return air temperature is reduced), and the heat compensation plate can adjust the return air temperature to achieve the effect of constant outlet air temperature.
The usage that more has practical meaning is, it is too big to detect humidity in the return air when first humidity transducer, when needing to dehumidify, the heat compensation device return circuit is opened, the highly compressed refrigerant temperature of medium temperature further reduces, the refrigerant flows through the evaporimeter afterwards, it is more obvious to the cooling effect of return air, more moisture condensation water is discharged in the return air this moment, then the return air flows through the heat compensation board again, relative humidity after the heating further reduces, reach good dehumidification effect this moment promptly.
The opening degree of the second electric control valve is adjusted according to the temperature and the humidity, so that the flow of the refrigerant in the evaporator and the flow of the refrigerant in the thermal compensation device are different (the refrigerant can flow through two channels simultaneously, and only the flow is different), and the purpose of adjusting the temperature is achieved more flexibly. The heat compensation device only plays a role in compensating and heating, the refrigeration power of the evaporator at any time is not less than 2 times of the maximum heat compensation power of the heat compensation device, in addition, when the second electric control valve is completely closed, and when the refrigerant completely flows through the heat compensation device, the return air cooling amplitude (relative to the non-working state of the heat compensation device) is not more than 5 degrees and is generally controlled to be about 3 degrees, and the opening degree a of the second electric control valve (the larger the opening degree of the second electric control valve is, the smaller the refrigerant flow in the heat compensation device is) is inversely related to the difference b between the first humidity sensor and the rated humidity.
