Air conditioning system

Abstract

The invention discloses an air conditioning system which comprises a compressor, a wind side heat exchanger, an air conditioner side heat exchanger, a hot water side heat exchanger, a first four-way valve, a second four-way valve and a third four-way valve. Four connectors of the first four-way valve are communicated with the output end of the compressor, the input end of the compressor, one connector of the second four-way valve and a first connector of the hot water side heat exchanger respectively. Four connectors of the second four-way valve are communicated with one connector of the first four-way valve, a first connector of the wind side heat exchanger, a first connector of the air conditioner side heat exchanger and the input end of the compressor respectively. The air conditioning system further comprises a first throttling element, a first check valve, a second throttling element and a third throttling element, and further comprises a second check valve and a liquid storage tank, wherein the second check valve and the liquid storage tank are sequentially connected in series, and any two of the first throttling element, the second throttling element, the third throttling element and the second check valve are communicated with each other through a pipeline. By means of the air conditioning system, the problem that the switching modes of an existing air conditioning system are not comprehensive enough can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically, relates to an air conditioning system. Background technique [0002] With the world's increasingly tight energy sources, the reduction of fossil fuels and the significant increase in energy demand, people are paying more and more attention to new ways of saving energy and efficient utilization of energy. Especially for the heat generated during the normal operation of the air-conditioning system, people have studied and realized many kinds of air-conditioning heat recovery technologies, thereby reducing the direct consumption and emission of energy, and achieving the purpose of energy saving and environmental protection. However, the air conditioner heat recovery devices in the prior art generally use electromagnetic valves for communication, so that only three or more of cooling, heating, hot water heating, heating defrosting, hot water defrosting, and hea...
