Abstract

A large energy-storage type air source heat pump hot water unit relates to a heat pump hot water unit. The invention is designed to solve the problems that the existing heat pump system for supplying hot water completely realizes the supply of hot water by electric heating when an air-conditioner stops running and does not have the energy storage function simultaneously. Four valves of a four-way reversing valve are connected with a compressor, a plate heat exchanger, a gas-liquid separator and an outdoor heat exchanger, the outdoor heat exchanger is connected with a capillary, the capillary is connected with a dry filter through an electronic expansion valve, the dry filter is connected with the plate heat exchanger, the gas-liquid separator is connected with the compressor, two ends of a heat-exchange coil in a heat storage tank are respectively connected with two ends of a heat-exchange pipe in the plate heat exchanger, a hot water circulation pump is arranged on a pipeline between the heat storage tank and the plate heat exchanger, and a hot water supply pump is arranged on an output end of the heat storage tank. The large energy-storage type air source heat pump hot water unit can realize the direct water supply, the heat storage at night, the heat storage in winter, the defrosting and other operations and save electric energy by 70 percent compared with an electric water heater and an electric boiler.

Description

technical field [0001] The invention relates to a heat pump water heater unit, in particular to an energy storage type air source heat pump water heater unit. Background technique [0002] At present, the heat pump systems with hot water supply are mainly operated by air conditioners. The hot water supply is only to recover the condensation heat of the air conditioning system. When the air conditioner is running, an auxiliary electric heater must be installed. When the condensation heat is not enough, the electric heater is directly used. Heating, while the hot water supply is completely realized by electric heating when the air conditioner stops running and in winter and transitional seasons, the energy saving is not obvious, and the existing heat pump system for hot water supply does not have energy storage function. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the hot water supply of the existing heat pump system f...
