Cross the 3rd magnetic valve 4c to continue to condense into the second air-cooled condenser 6b, then the second reservoir is entered by the second check valve 7b
8b), refrigerant enters second throttle 10b reducing pressure by regulating flow after the second reservoir 8b outflows by the second device for drying and filtering 9b
Afterwards, absorb heat and evaporate into the second wind-cooled evaporator 11b, then by being sucked after the second gas-liquid separator 1b by the second compressor 2b.
Highly humid air processing procedure is as follows：The suction highly humid air of centrifugal blower 14 first passes through the first wind-cooled evaporator 11a, quilt
Refrigerant heat absorption therein, air themperature reduces and separates out water, then by the second wind-cooled evaporator 11b, by refrigerant therein
Heat absorption, air themperature drop it is lower and continue separate out water, the air after dehumidifying sequentially pass through the second air-cooled condenser 6b and
First air-cooled condenser 6a carries out temperature adjustment processing, then is sent.Humidity sensor 12 senses the air after once dehumidifying
Relative humidity, and pass moisture signal back controller, controller controls the second compressor 2b's to add unloading, so as to adjust the second pressure
Contracting machine 2b refrigerating capacity, and then two grades of dehumidifying effects are controlled, the low relative humidity of air-supply had both been can guarantee that, energy-conservation effect can be reached again
Really.
Temperature adjustment process is as follows：Temperature sensor 13 senses leaving air temp signal, and passes signal back controller, and controller leads to
The opening and closing of first, second, third and fourth magnetic valve of control (4a, 4b, 4c, 4d) is crossed, to control refrigerant whether air-cooled by first and second
Condenser (11a, 11b), and then whether the Cryogenic air after dehumidifying is controlled with being made in first and second air-cooled condenser (11a, 11b)
Cryogen exchanges heat, and raises air themperature, the aperture of controller control electric stream adjustable valve 5, so as to control cooling water band
The condenser heat walked and the condenser heat for heating air, and then regulating outlet air temperature.
