Problems solved by technology

[0007] The above methods did not greatly increase the COP value. The main reason is that the heat absorption and heat release are not used independently, that is, the heat release cannot be independently refrigerated without relying on or not completely relying on heat absorption.

Embodiment Construction

[0019] Such as figure 1 As shown, the heat Q absorbed by the heat pump system is used for refrigeration, and the heat Q+W released by the heat pump system is used to regenerate the desiccant, where W is the work input by the heat pump, and the regenerated desiccant a4 is used to regenerate the gas For the dehumidification of a1, the gas a1 is dehumidified to a2, and the desiccant a4 absorbs the moisture in the gas a1 and becomes a3, and returns to the desiccant regenerator for regeneration and recycling.

[0020] Such as figure 2 As shown, at least part of the heat generated in the dehumidification process is as Q 2 Not absorbed by the heat pump system, but discharged to the environment by other means. Since the temperature of the dehumidifier and the gas after dehumidification is relatively high, some high-temperature cold sources can be used for cooling.

[0021] Such as image 3 As shown, the gas c1 first passes through the cooler to reduce the temperature and becomes ...

Abstract

The invention discloses a method for treating air by a combined heat pump and dehumidification system. The heat absorption of the heat pump system is used for refrigeration, and the heat release of the heat pump system is used to regenerate the dehumidifier, and the regenerated dehumidifier is used to dehumidify the air. The invention utilizes the heat absorption and refrigeration of the heat pump, and at the same time utilizes the heat release of the heat pump, which is generally a heat source below 60°C, to independently dehumidify and refrigerate, thereby greatly improving the refrigeration coefficient of the heat pump system; combining artificial refrigeration with indirect evaporative cooling and refrigeration , so as to improve the seasonal energy efficiency ratio of the air-conditioning system; while providing fresh air for the air-conditioning room, increase the net cooling capacity of the room without increasing energy consumption.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a method for treating air by a combined heat pump and dehumidification system. Background technique [0002] A heat pump has an endothermic side and an exothermic side. The heat emitted by the exothermic side is equal to the heat absorbed by the endothermic side plus the work done by the heat pump. At present, there are three ways to use both the endothermic and exothermic heat of the heat pump system: [0003] One is to condense and dehumidify the gas through the endothermic side first, and then heat it through the exothermic side, the purpose of which is to dehumidify the gas. [0004] One is that the heat absorption of the heat pump is used for refrigeration, and the heat release is used to make hot water and other uses. [0005] Both of the above are special-site and specific-purpose practices. [0006] The third is a dehumidification heat pump syste...
