Abstract

The invention is a kind of parallel heat pump temperature and humidity adjusting unit, which belongs to cooling, air conditioning and humidity eliminating technology field. The invention has a compressor, outdoor heat exchanger, the first and the second indoor heat exchanger and the restriction device, all of which are connected into a cooling circle through the cooling agent pipe, the outdoor heat exchanger and the second indoor exchanger are paralleled, the unit also includes a four-way valve. The invention can realize four kinds of different running mode through the four-way valve, and realizes quick frost eliminating without stop. The invention can satisfy the demands of large change of cold and hot load, and it can carries on micro adjustment through the on / off of the two electromagnetism valves on the two paralleled heat exchanger branches and adjusting the wind quantity and the water quantity in outdoor heat exchanger. The invention upgrades the utilization ratio of the device.

Description

technical field

[0001] The invention relates to a refrigeration dehumidification device, in particular to a heat pump type temperature-regulating dehumidification device, which belongs to the technical fields of refrigeration, air conditioning and dehumidification. Background technique

[0002] Refrigerated dehumidifiers use evaporators to cool and dehumidify the air, and recover the condensation heat of the system to make up for the heat lost in the air due to cooling and dehumidification. And dehumidification and temperature control of high humidity space.

[0003] At present, there are two main types of refrigerated dehumidifiers in my country: heating type and temperature regulating type. The heating type dehumidifier is composed of an indoor condenser and an indoor evaporator. While dehumidifying the room, it also dissipates the condensation heat to the room to heat the indoor air. In order to further improve the heating capacity and the outlet air temperature, an eva...
