Abstract

The invention discloses an air-cooled cold and hot water unit. The air-cooled cold and hot water unit comprises a four-way reversing valve, a water side heat exchanger, a first electronic expansion valve and a wind side heat exchanger circularly connected in a circulating loop in sequence, and further comprises an auxiliary heat exchanger, a second electronic expansion valve, an electromagnetic valve, an auxiliary pipeline and a control valve, wherein the auxiliary heat exchanger is connected to a pipeline of the four-way reversing valve and the wind side heat exchanger; a parallel pipeline is formed between the second electronic expansion valve and the electromagnetic valve; the control valve is connected to the auxiliary pipeline and a pipeline between the four-way reversing valve and the water side heat exchanger; and the control valve is used for controlling communication between the four-way reversing valve and the water side heat exchanger or the communication between the four-way reversing valve and the auxiliary pipeline. The air-cooled cold and hot water unit is low in mechanical shock during defrosting, and prevents the inspiration of a compressor from taking liquid.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an air-cooled hot and cold water unit. Background technique [0002] In the prior art, the air-cooled hot and cold water unit is used as the cold and heat source of the central air-conditioning system. When heating in winter, the air-side heat exchanger (finned heat exchanger) on the evaporating side exchanges heat with the air easily. Frosting on the surface of the fins will affect the heat transfer efficiency of the fins, thereby affecting the capacity and reliability of the unit. When the frost layer accumulates to a certain extent, the heating capacity is significantly attenuated, and defrosting must be carried out. At present, the most common defrosting method is reverse cycle defrosting. During reverse cycle defrosting, heat is absorbed from the hot water side, and the water temperature drops significantly, which affects the comfort of users. When switchin...
