In the low dew point environmental control of biopharmaceutical and new energy fields, rotary dehumidification is also indispensable. Rotary dehumidification is an adsorption dehumidification.

[0047] Reference Figures 1 to 3 In some embodiments of the first aspect of the present invention, a rotary dehumidification system with anti-condensation step temperature control includes: a fresh air inlet, a heat pump main circuit, a heat exchanger 500 and a rotary dehumidification unit 600.

[0048] The heat pump main circuit includes a compressor 300 , a first evaporator 400 , a temperature adjustment mechanism 100 and a first condenser 200 which are connected in sequence to form a circuit.

[0049] The temperature control mechanism 100 is connected to the fresh air inlet. A first pipe is provided inside the heat exchanger 500, one end of the first pipe is connected to the temperature control mechanism 100, the other end of the first pipe is connected to the first condenser 200, and the first condenser 200 is connected to the regeneration air inlet of the rotary dehumidification unit 600.

[0050] A second pipe is provided inside the heat exchanger 500 , the first pipe intersects with the second pipe, one end of the second pipe is connected to the regeneration exhaust port of the rotary dehumidification unit 600 , and the other end of the second pipe is connected to the first evaporator 400 .

[0051] Fresh air flows in from the fresh air inlet and flows through the temperature control mechanism 100. The temperature control mechanism 100 can perform air mixing and heat exchange processing on the current fresh air, and output the mixed air after temperature adjustment. Through the air mixing and heat exchange processing, the mixed air temperature of the mixed air can be adjusted.

[0052] In the heat exchanger 500, the regenerated exhaust air output by the rotary dehumidification unit 600 can undergo heat exchange processing with the mixed intake air through the first pipe and the second pipe. The treated mixed intake air flows through the first condenser 200 for heat exchange processing to obtain the regenerated intake air used by the rotary dehumidification unit 600.

[0054] Among them, reference Figure 1 In this utility model, FA is the current fresh air and EA is the heat recovery exhaust air.

[0055] The temperature regulating mechanism 100 can adjust the mixed air temperature of the mixed intake air by performing mixed air processing and heat exchange processing on the current fresh air, so that when the regenerated exhaust air performs indirect heat exchange with the mixed intake air through the heat exchanger 500, no condensed water is precipitated or condensed in the heat exchanger 500, and the temperature regulating mechanism 100 obtains a greater degree of supercooling, improves the proximity of the condensation temperature and the wind temperature, and realizes first-order sensible heat recovery without condensation; through the first evaporator 400 to process the treated regenerated exhaust air, the first evaporator 400 can obtain a larger processing enthalpy difference, and the corresponding first condenser 200 in the heat pump main circuit can have more heat to heat the mixed intake air, obtain regenerated intake air of suitable temperature, reduce the supplement of the rear stage regeneration heat of the rotary dehumidification unit 600, and realize the improvement of the heat recovery amount of the second-order heat pump coupling; solve the problems of condensation in the exhaust duct during sensible heat recovery of the existing air conditioner, damage to the rotary dehumidification unit 600, and low heat recovery efficiency and sensible heat exchange efficiency.

[0056] Reference Figures 1 to 3 In some embodiments of the first aspect of the present utility model, the dehumidification system further includes: an exhaust vent.

[0057] The first evaporator 400 is connected to the exhaust port. The first evaporator 400 is used to perform heat exchange on the treated regeneration exhaust air to generate heat recovery exhaust air. The exhaust port can discharge the heat recovery exhaust air.

[0058] In one embodiment, the rotary dehumidification unit 600 dehumidifies the indoor air through the regeneration air intake. After the dehumidification, the indoor air is dry and has a suitable temperature. After the dehumidification, the regeneration air intake is dehumidified to obtain regeneration exhaust air. The regeneration exhaust air flows through the heat exchanger 500 and undergoes a first heat exchange process through the second pipe. The treated regeneration exhaust air flows through the first evaporator 400 to undergo a second heat exchange process to obtain heat recovery exhaust air. The heat recovery exhaust air can be discharged through the exhaust port or enter the temperature control mechanism 100 to perform mixed air processing on the current fresh air. Wherein, referring to Figure 1 In this utility model, FA is the current fresh air and EA is the heat recovery exhaust air.

[0059] Reference Figures 1 to 3 In some embodiments of the first aspect of the present utility model, the temperature control mechanism 100 includes: a second condenser 103 , a bypass air valve 101 and a heat recovery air valve 102 .

[0060] The second condenser 103 is connected to one end of the first pipe in the heat exchanger 500, the first evaporator 400, and the first condenser 200. The second condenser 103 can adjust the mixed air temperature of the mixed intake air by adjusting the condensation amount.

[0061] The air inlet of the bypass damper 101 faces the fresh air inlet, while the air inlet of the heat recovery damper 102 faces the exhaust outlet. The fresh air inlet and exhaust outlet are located on the same side. The bypass damper 101 is located on one side of the heat recovery damper 102, which is located near the first evaporator 400. The air outlets of the bypass damper 101 and the heat recovery damper 102 both face the second condenser 103.

[0062] Among them, the current fresh air can flow through the bypass air valve 101 to be mixed with the air, and the heat recovery exhaust air can flow through the heat recovery air valve 102 to be mixed with the current fresh air. The second condenser 103 is a temperature-adjustable condenser.

[0063] The bypass air valve 101 is provided with a first actuator, which can adjust the bypass opening of the bypass air valve 101 to adjust the proportion of fresh air in the mixed intake air, thereby adjusting the mixed air temperature.

[0064] The heat recovery air valve 102 is provided with a second actuator, which can adjust the recovery opening of the heat recovery air valve 102 to adjust the heat recovery exhaust air ratio in the mixed intake air, thereby adjusting the mixed air temperature.

[0065] Since the regenerated exhaust air is of high temperature, in the heat exchanger 500, the mixed intake air and the regenerated exhaust air are heat exchanged, and the fresh air temperature will be lower than the mixed air temperature after the heat exchange. According to this energy efficiency level, the upstream and downstream flow relationship between the first condenser 200 and the second condenser 103 is determined to implement a temperature control strategy that requires the heating side to be hotter (the first condenser 200 adjusts the regenerated intake air to be hotter) and requires temperature adjustment to measure the temperature to be less hot (the second condenser 103 adjusts the mixed air temperature to be less hot).

[0066] The mixed air temperature of the mixed intake air output to the heat exchanger 500 is adjusted through the second condenser 103, the bypass air valve 101 and the heat recovery air valve 102, and no condensed water or condensation is precipitated in the heat exchanger 500. The temperature control mechanism 100 obtains a greater degree of supercooling, improves the proximity of the condensation temperature and the air temperature, and realizes first-order sensible heat recovery without condensation. The first evaporator 400 processes the treated regenerated exhaust air, and the first evaporator 400 can obtain a larger treatment enthalpy difference. The corresponding first condenser 200 in the heat pump main circuit can have more heat to heat the mixed intake air, obtain regenerated intake air of suitable temperature, reduce the supplement of the rear stage regeneration heat of the rotary dehumidification unit 600, and realize the improvement of the heat recovery amount of the second-order heat pump coupling. It solves the problems of condensation in the exhaust duct during sensible heat recovery of the existing air conditioner, damage to the rotary dehumidification unit 600, and low heat recovery efficiency and sensible heat exchange efficiency.

A first filter 630 removes air particles carried in the outdoor air. The filtered outdoor air then flows through the evaporator 640. The evaporator 640 performs a primary heat exchange on the outdoor air.
