Abstract

The invention relates to a water tank waste heat recovery heat pump water heater system with an adsorption type heat storage device. The water tank waste heat recovery heat pump water heater system comprises a water-refrigerant heat exchanger, a water tank, a four-way reversing valve, a compressor, an air-refrigerant heat exchanger, a fan, the heat storage device and a throttling device, wherein the water-refrigerant heat exchanger and the heat storage device can be connected in series or in parallel. Compared with the prior art, the water tank waste heat recovery heat pump water heater systemwith the adsorption type heat storage device can well solve the problem of waste heat of a water tank of a heat pump water heater. The structure of a heat pump system is improved, reverse refrigeration is carried out by converting the flow direction of a refrigerant, waste heat in the water tank of the heat pump water heater is stored in the adsorption type heat storage device, the system structure is simple, and long-time temperature storage of heat can be achieved.

Description

technical field [0001] The invention relates to a heat pump water heater system, in particular to a water tank waste heat recovery heat pump water heater system with an adsorption heat storage device. Background technique [0002] Energy, as a consumable resource, is becoming increasingly scarce, and it is becoming more and more important to improve energy utilization through various means. At present, household water heaters have been popularized, and a large amount of hot water is used in daily life, such as domestic domestic hot water (hot water after bathing, hot water in the kitchen), but after the hot water is used, there is still water in the water tank of the heat pump water heater. Lots of hot, hot water. Usually, the high-temperature hot water in the water tank is naturally cooled, causing a large amount of heat loss. This patent is an improvement on the heat storage type heat pump water heater. The heat storage type heat pump water heater is provided with a wate...
