Multi-condenser combined solar jet air-conditioning unit

Abstract

A multi-condenser combined solar jet air-conditioning unit comprises a solar heat collection hot water loop, a refrigerant loop, a domestic hot water loop and an air-conditioning water loop. Condensed heat of a system is utilized sufficiently, domestic hot water is supplied, and solar energy sources are utilized more sufficiently. Problems of heat pollution generated in operation of finned tube air-cooled condensers to environments and solar heat waste caused by cold and heat mixing due to overhigh temperature of domestic hot water directly from a hot water tank in summer are relieved mainly. In summer, a part of the condensed heat is used for producing the domestic hot water, the flow process of the water production system is controlled by switching and on and off of valves, refrigerating, heating and domestic hot water producing processes can be carried out independently, or the refrigerating, heating and domestic hot water producing processes can be carried out simultaneously. Expectively, the multi-condenser combined solar jet air-conditioning unit can be applied to an air-conditioning cold and hot water supplying system, a low-temperature air supplying system and a cold storage air-conditioning system well.

Description

technical field [0001] The invention belongs to the field of air conditioning and refrigeration, and in particular relates to a solar jet air conditioning unit which utilizes solar energy to supply heat, cool and provide domestic hot water. Background technique [0002] With the further aggravation of the energy crisis, the utilization of solar energy has become the focus of attention. In the solar energy utilization technology, the solar jet refrigeration system is favored by everyone because of its simple structure, few moving parts, and low cost. It is more and more widely used in the field of air conditioning and refrigeration. However, the survey of its use shows that there are two deficiencies in the operation of the conventional solar jet air conditioning system. One: the system condenser mostly uses a finned tube air-cooled condenser, and the condensation temperature of the condenser is relatively low when it is working. A higher value will lower the cooling coeffic...
