Abstract

The invention relates to technical field of air conditioning, in particular to an energy storage-type air conditioning system. The energy storage-type air conditioning system comprises a compressor, a four-way valve, an outdoor heat exchanger, a first stop valve, an energy storage module and an indoor heat exchanger which are connected in sequence; the energy storage module and the indoor heat exchanger are respectively connected with the four-way valve through a second stop valve; the energy storage module comprises an energy storage coiler, a first expansion valve and a second expansion valve, wherein the first expansion valve and the second expansion valve are respectively arranged at two ends of the energy storage coiler; the energy storage coiler is arranged in a phase-change material; the first expansion valve is connected with the first stop valve; the second expansion valve is connected with the indoor heat exchanger; through the energy storage module and by controlling the opening of all electromagnetic valves and the expansion valves, various running modes of the system are realized, the performance of the existing air conditioning system is improved, and the energy storage-type air conditioning system can use electricity in off-peak hours.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy storage type air conditioning system. Background technique [0002] At present, energy-storage air conditioners are generally only used in large-scale HVAC systems, and their main function is to balance the power grid by shifting peak power consumption and shifting peaks to fill valleys. However, energy storage systems are rarely used in small heat pump air conditioners. According to the survey, there is no small heat pump air conditioner using energy storage system in the domestic air conditioner market. [0003] However, most of the existing air-conditioning systems have problems such as poor heating capacity, poor heating and cooling energy efficiency, need to stop for defrosting, etc., and cannot use peak electricity. Contents of the invention [0004] (1) Technical problems to be solved [0005] The object of the present invention is to provide an ene...
