Abstract

The invention provides an air conditioning system. The air conditioning system comprises an indoor heat exchanger, a heat storage tank and a control valve bank. The indoor heat exchanger, the heat storage tank and the control valve bank are connected to an air conditioning pipeline. The control valve bank can selectively have the following three states that the heat storage tank is controlled to be connected with the indoor heat exchanger in series; or the heat storage tank is controlled to be connected with the indoor heat exchanger in parallel; or the heat storage tank is controlled to be isolated from a refrigerant circulation flow path under the heating circulation state of the air conditioning system and the refrigerant circulation flow path under the refrigeration circulation state of the air conditioning system. When the air conditioning system works, the heat storage tank can be in the different states according to actual working requirements, and therefore the utilization rate of the heat storage tank is increased.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning equipment, and more specifically, to an air-conditioning system. Background technique [0002] In the existing air-conditioning system, the heat storage tank and the indoor unit are only used in series or in parallel, and the heat storage tank absorbs heat for use in defrosting during heating. The air-conditioning system has a low utilization rate of the heat storage tank, and adopts the defrosting method of the heat storage tank, which may easily cause defects such as a slow rise in the air temperature of the indoor unit due to the heat storage tank absorbing part of the heat when the heating starts after defrosting. Contents of the invention [0003] The present invention aims to provide an air conditioning system to solve the problem of low utilization rate of heat storage tanks in the prior art. [0004] In order to solve the above technical problems, the present invention ...
