Problems solved by technology

In these occasions where both cold and heat are required, the traditional solution is to supply cold and heat separately and are not related to each other. This makes the heat emitted by the air conditioning system unused, but is discharged into the atmosphere in vain, and produced The heat required for hot water consumes additional energy
Or the cooling capacity generated wh...

Abstract

The invention discloses a cold and heat dual-purpose heat pump system with phase-change cold storage and heat storage functions. The cold and heat dual-purpose heat pump system mainly consists of a hot water circulating device, a cold water circulating device, a compressor and a throttling valve. The cold and heat dual-purpose heat pump system with the phase-change cold storage and heat storage functions has the advantages that the hot water circulating device and the cold water circulating device are respectively provided with a phase-change heat storage tank and a phase-change cold storage tank; each working state of the hot water circulating device is correspondingly combined with each working state of the cold water circulating device, so that multiple running modes are realized, the waste of one part of cold energy or heat energy caused by unbalance of cold energy or heat energy in quantity and nonsynchronous time at the cold and heat demand sides is avoided, the maximum utilization of cold energy and heat energy of a dual-purpose heat pump device is basically realized, and the loss of energy source is reduced.

Description

technical field [0001] The invention relates to heat pump technical equipment, in particular to a cold and heat dual-purpose heat pump system with phase change cold storage and heat storage. Background technique [0002] A heat pump is a device that transfers heat from a low-temperature environment to a high-temperature environment based on the principle of refrigeration. In a heat pump device, for every unit of energy consumed by the compressor (electric energy for an electric-driven compressor), the evaporator can absorb about 3 to 6 times the heat from the low-temperature environment (or called the discharged cooling capacity), and its The condenser can discharge the heat of the sum of the aforementioned cooling capacity and energy consumption to the high temperature environment. [0003] In practical applications, most heat pump systems only use the cooling or heat on one side. The device that only uses the cooling capacity is an air conditioner, and the heat generated ...
