Abstract

The invention provides a semi-decoupled cooling dehumidification and graded cooling dehumidification heat pump system. The system comprises a closed refrigerant system and two open air channels operated in parallel. The invention further provides a cooling dehumidification and graded cooling method. A dehumidifying evaporator and an evaporator serially connected are adopted to replace an evaporator in a compressive cycle and a dehumidifying evaporator in a traditional dehumidifying heat pump cycle; a circular condensation side is formed by another dehumidifying heat exchanger; and thermal circulation of continuous heat and moisture load treatment is realized through switching of a four-way reversing valve and an air way. Compared with the prior art, the system is compact in structure and lower in cost, and can realize efficient treatment and flexible matching of heat and moisture loads.

Description

technical field [0001] The invention relates to a system in the technical field of dehumidification air-conditioning heat pumps, in particular to a dehumidification heat pump system with semi-decoupled cooling, dehumidification and staged cooling. Background technique [0002] With the improvement of people's living standards, the energy consumption of building air conditioning systems has become the main source of total energy consumption in society. The traditional compression air-conditioning system is widely used in buildings at present. It realizes the centralized treatment of heat and humidity load through condensation dehumidification method, which leads to the operation of the overall cycle at a lower evaporation temperature, and the energy efficiency of the cycle is not high. The cycle for independent treatment of heat and humidity loads is composed of desiccant air-conditioning sub-cycle and traditional compression air-conditioning sub-cycle. Desiccant air conditi...
