Air-conditioning system with auxiliary defrosting system

Abstract

The invention discloses an air-conditioning system with an auxiliary defrosting system, which comprises a compressor, a condenser, a throttle valve, an evaporator, a steam-liquid separator, a four-way reverse valve and an energy storage tank, wherein energy storage media are contained inside the energy storage tank, a pipeline arranged between an air outlet of the compressor and the four-way reversing valve passes through the energy storage media arranged inside the energy storage tank, a defrosting heat radiation device is also arranged at the back part of the evaporator and is communicated with the energy storage tank through an auxiliary pipeline, an auxiliary driving pump for driving the circulation of the energy storage media inside the energy gas storage tank is arranged on the auxiliary pipeline, and is electrically connected with a control system, the control system controls the synchronous work with a defrosting system of the air-conditioning system per se, and the energy storage tank is in a telescopic structure. The air-conditioning system has the advantages that the defrosting speed can be accelerated, the defrosting efficiency is improved, and the defrosting is clean.

Description

technical field [0001] The invention relates to the field of heating and ventilation, in particular to an air conditioning system with a defrosting auxiliary system. Background technique [0002] Such as figure 1 , the defrosting of the existing air conditioning unit is that when the system reaches the defrosting condition, the steam discharged from the air outlet of the compressor enters the evaporator 14 through the four-way valve 16 for direct defrosting and cooling, and then becomes a high-temperature and high-pressure liquid and then passes through the throttle valve 13 throttling into the condenser 12 to evaporate into low pressure and low temperature, the defrosting speed is average, and the defrosting efficiency needs to be further improved, so the energy consumption will increase, and the environmental impact on its air-conditioned space is also greater. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
