Abstract

The present invention relates to the technical field of combined heating and cooling systems, in particular to a heat storage and cold storage system, comprising a compressor, a first heat exchanger, a throttling device and a second heat exchanger connected in series in sequence, the second heat exchanger The heat storage device is connected with the compressor; the cold storage device has multiple, respectively connected in parallel with one of the first heat exchanger or the second heat exchanger; the heat storage device has multiple, respectively connected with the first heat exchanger or the second heat exchanger The other device is connected in parallel; there are multiple valves, which are respectively arranged upstream and downstream of the compressor, the cold storage device, the heat storage device, the first heat exchanger, and the second heat exchanger. The heat storage and cold storage system provided by the present invention has the advantages of high energy utilization rate, no exacerbation of peak-valley contradictions in power supply, and the ability to switch between various working conditions to achieve good user experience.

Description

technical field [0001] The invention relates to the technical field of combined heating and cooling systems, in particular to a heat storage and cold storage system. Background technique [0002] my country has a vast territory. In northern China, water heaters and refrigeration air conditioners are used for heating and cooling in summer, and heating and water heaters are used for heating in winter; in southern China, water heaters and refrigeration air conditioners are used for heating and cooling in summer, and there are various heating methods in winter. Various, mostly electric heating devices and air energy heat pump devices, which consume a lot of power, and multiple devices must be used in different seasons, thus causing a waste of resources. At present, the existing technology such as Chinese patent document CN202885134U discloses a cold storage heat storage type hot water air conditioner, including a main box, a compressor, a four-way valve, an air conditioner heat e...
