Abstract

A multi-condenser combined solar jetting air conditioning unit comprises a solar heat collection hot water circuit, a refrigerating fluid circuit, a living hot water circuit and an air conditioning water circuit. The multi-condenser combined solar jetting air conditioning unit fully utilizes condensation heat of a system to provide living hot water, and more fully utilizes solar resources, and mainly relieves the problems that a finned tube air-cooled condenser causes heat pollution at operation, and in summer the living hot water is directly taken from a hot water tank, however, overhigh temperature can lead to mixing of cold water and hot water which causes waste of the solar energy. In summer, a part of the condensation heat is utilized to obtain the living hot water. Through switching, opening and closing of a valve, the flow path of a water system is controlled, a cooling process, a heat supply process and a living hot water making process can be carried out independently. Further, the cooling process and the living hot water making process, and the heat supply process and the living hot water making process can be carried out simultaneously. The multi-condenser combined solar jetting air conditioning unit is expected to be well applied to an air condition cold and hot water double supply system, a low temperature air supply system and a cool storage air-conditioning system.
