Air conditioning system

Abstract

The invention relates to an air conditioning system which comprises a dehumidifier, a second fresh air and return air mixing mechanism and a second surface cooling mechanism. The dehumidifier comprises a first fresh air and return air mixing mechanism, a first surface cooling mechanism and an air outlet mechanism which are sequentially arranged in the air direction. Refrigeration fluid in a refrigeration pipeline sequentially flows through the first surface cooling mechanism and the second surface cooling mechanism, that is, the refrigeration fluid firstly flows into the first surface coolingmechanism for dehumidification treatment, the temperature of the refrigeration fluid is increased, the refrigeration fluid flows out from the first surface cooling mechanism and then flows into the second surface cooling mechanism, and therefore the temperature of the refrigeration fluid entering the second surface cooling mechanism can be increased. The refrigeration fluid with the temperature increased to a certain degree is utilized for cooling treatment on air in the second surface cooling mechanism, and therefore temperature and humidity independent control of the full air conditioning system can be achieved through a single cold source. The air conditioning system is simple in structure, and the quantity of related equipment is small.

Description

technical field [0001] The invention relates to an air-conditioning system, belonging to industrial air-conditioning systems. Background technique [0002] In order to solve the phenomenon of cold and heat offset and energy waste in the heat and humidity treatment process of the technological air-conditioning system in summer, the air-conditioning system usually adopts the way of secondary return air for heat and humidity adjustment. Cooling or reducing the consumption of reheating energy to alleviate the energy waste of cold and hot offsets. [0003] Moreover, most of the existing air-conditioning systems are based on solution heat recovery and high- and low-temperature chiller dual-cooling source dehumidification technology. One of the cooling sources removes indoor residual humidity, and the other cold source removes indoor residual heat. If two cold sources are used, two refrigeration systems, as well as refrigeration-related equipment and pipelines, etc. need to be set...
