Abstract

The invention discloses a host machine of an air cooling and water cooling type cold and hot water air conditioner, comprising a compressor, a four-way valve, an electromagnetic valve, a double-pipe heat exchanger, a fin type heat exchanger, a one-way valve, a liquid reservoir, an electronic expansion valve, an enthalpy increasing plate exchange unit, a plate exchange unit and an air distributing member, wherein the four-way valve is arranged between the compressor and the air distributing member; the other end of the four-way valve is connected with the plate exchange unit; the other end of the plate exchange unit is connected together with the fin type heat exchanger and the double-pipe heat exchanger through the electromagnetic valve respectively; a one-way valve assembly is further disposed between the fin type heat exchanger and the plate exchange unit; and the one-way valve assembly is connected with the liquid reservoir and the enthalpy increasing plate exchange unit. The host machine of the air cooling and water cooling type cold-hot water air conditioner disclosed by the invention can satisfy different demands of users; in addition, a modular design has the advantages of high precision, high efficiency, high reliability, compact structure, flexible use, convenient operation, and the like.

Description

Technical field [0001] The invention relates to cold and heat source equipment in air conditioning, cooling and heating. Background technique [0002] In the air conditioning cold and heat source technology, the outdoor side of the air conditioner produced by the prior art can only operate in a single cooling mode, which cannot keep the whole machine running efficiently in winter and summer. That is, the energy efficiency ratio of the water-cooled unit is higher than that of the air-cooled unit during cooling operation, but the outdoor side can only operate in the cooling mode in the water-cooled mode, and cannot operate in the heating mode in the winter; the air-cooled unit can only operate in the air-cooled mode. Under low temperature conditions, the energy efficiency ratio of operation is not high, and the energy efficiency ratio is extremely low when the heating conditions are operated in a low temperature environment, and it can not even start operation. [0003] Existing uni...
