Temperature and humidity adjusting system and method for air for process

Abstract

The invention discloses a temperature and humidity adjusting system and method for air for a process. The system comprises an air processing chamber, an air regenerating chamber and an air cooling chamber. A first evaporator, a second evaporator, a dehumidifying side of a dehumidifying rotating wheel and an air processing fan are sequentially arranged in the air processing chamber. A regenerating fan, a regenerating side of the dehumidifying rotating wheel and a second condenser are sequentially arranged in the air regenerating chamber. A first throttling device, a first condenser and a cooling fan are arranged in the air cooling chamber. The system and method adopts the low temperature regenerating dehumidifying rotating wheel and utilizes a compression refrigeration system to exhaust heat to achieve regeneration. Meanwhile, aiming at the characteristic of low outdoor temperature in transitional seasons, regenerating temperature is ensured by adjusting air quantity of the regenerating fan, freezing dehumidifying refrigeration quantity and dehumidifying quantity of the dehumidifying rotating wheel are adjusted, and air outlet temperature and humidity are adjusted. The system and method has the advantages of saving energy, being high in efficiency and good in adjustability and the like.

Description

technical field [0001] The invention relates to a temperature and humidity adjustment system and method for process air. Background technique [0002] Many processes, such as spraying and other processes, have requirements for the temperature and humidity of the wind, and they need to be guaranteed all year round, which is generally higher than that of air conditioning. If fresh air is required, the relative humidity required is lower, such as less than 50%. [0003] Conventionally, refrigeration and high-temperature regenerative dehumidification rotors are used to achieve this. Generally, in summer, freezing dehumidification refrigeration and high-temperature regeneration dehumidification rotors are used for combined operation; while outdoor air enthalpy is low, such as in transitional seasons, only high-temperature regeneration dehumidification rotors are used. Because the high temperature regenerative dehumidification rotor is used, both situations consume a lot of energy...

[0003] Conventionally, refrigeration and high-temperature regenerative dehumidification rotors are used to achieve this. Generally, in summer, freezing dehumidification refrigeration and high-temperature regeneration dehumidification rotors are used for combined operation; while outdoor air enthalpy is low, such as in transitional seasons, only high-temperature regeneration dehumidification rotors are used. Because the high temperature regenerative dehumidification rotor is used, both situations consume a lot of energy. The most unreasonable thing is that the energy consumption in the transition season is even higher than that in summer, because the outdoor temperature of the transition machine is low, and the energy consumption required for heating the regeneration air is higher than that in the summer. summer high
