Problems solved by technology

Due to the adiabatic heat and moisture exchange between the solution and the air in the filler, the flow rate of the solution is usually very large, resulting in high energy consumption for system transportation.
And the solution is cooled first and then sprayed in the filler, resulting in complicated air conditioning equipment and large volume

Embodiment Construction

[0012] see figure 1 , the solid line in the figure represents the refrigerant, and the dotted line represents the solution. The whole air conditioning system consists of a refrigeration cycle (compressor 1, evaporator 2, expansion valve 3, condenser 4) and a solution cycle.

[0013] The air conditioner system includes: a refrigeration cycle system and a solution cycle system. The refrigeration cycle system includes: compressor 1, evaporator 2, expansion valve 3 and condenser 4, and the solution cycle system includes: dehumidification device A, regeneration device B, solution reservoirs 5 and 6, solution pumps 7 and 8, and regulating valves Wait. The refrigerating capacity of the refrigeration cycle is used to cool the solution and enhance its dehumidification capacity, and the exhaust heat of the condenser is used to heat the regeneration solution. Fresh air (or indoor return air) is cooled and dehumidified in summer and heated and humidified in winter in device A. The air...

Abstract

The inventive air-conditioning system comprises refrigeration and solution cycle systems. The refrigeration cycle system has a compressor, an evaporator, an expansion valve and a condenser. The solution cycle system has a dehumidifier, a regenerating unit, a solution reservoir, a solution pump, a mixed solution valve and a control valve. Because of adding a solution cycle system, the invention can realize the accuracy independent control of temperature and humidity.

Description

technical field [0001] The invention relates to a temperature- and humidity-independently-controlled air conditioner used in the field of heating, ventilating and air-conditioning, which uses a solution as an auxiliary working fluid, and belongs to the field of energy technology. Background technique [0002] At present, air conditioners generally use the method of condensation dehumidification to adjust the humidity of the air. This method needs to cool the air below the dew point temperature to achieve the task of dehumidification. In many cases, although the air humidity (moisture content) meets the requirements, the temperature is too high. Low, and further reheating is needed to make the air supply parameters meet the requirements. Although this method can control the temperature and humidity of the air supply more accurately, there is double energy waste of over-cooling and reheating in the process. In many buildings, no reheating device is installed in the air-conditi...
