The invention relates to a temperature and humidity weak correlation control method for an air conditioning system. The method is characterized by comprising the following steps that firstly, the supply air temperature is controlled by adjusting the evaporation temperature or condensation temperature of a heat exchanger; and secondly, and the supply air humidity is controlled by adjusting the duration time of moisture absorption or moisture liberation of the heat exchanger. Compared with air adjusting device control strategies in issued patents or other documents, the method has the following advantages that firstly, the characteristic of weak correlation of the heat transfer and mass transfer processes of the heat-mass weak coupling heat exchanger is brought into full play, so that the independent temperature-humidity control flexibility of the temperature and humidity weak correlation control air conditioning system is improved, and high efficiency of the air conditioning system is fully guaranteed; and secondly, the control strategy is different from the previous control strategy which takes temperature control or humidity control as the principal thing, simultaneous control over temperature and humidity is realized, and thus the air supply comfort level of the air conditioning system is greatly improved.
Description
technical field [0001] The present invention relates to a control method of an air conditioning device, in particular to an air conditioning system constructed using a heat-mass weak coupling transfer heat exchanger. latent heat treatment capacity) control method designed for independent control requirements. Background technique [0002] Coating the surface of the heat exchanger with a moisture-absorbing material can constitute a heat exchanger that can efficiently process the latent heat of the air. Replace the finned tube heat exchanger in the traditional vapor compression refrigeration system with this kind of heat exchanger coated with desiccant, hereinafter referred to as dehumidification heat exchanger, to form a high-efficiency fresh air dehumidifier, hereinafter referred to as adsorption dehumidifier, has been There are the following air conditioning devices, for example, Chinese patents CN 1864033A, CN 101171459A, that is: in a vapor compression refrigeration cycl...
