Abstract

The invention relates to a heat pump water heater. The heat pump water heater comprises a heat storage water tank and a refrigerant circulating system which is provided with a compressor, wherein water in the heat storage water tank is heated by a heating heat exchanger or a condenser; the heating heat exchanger is provided with a heating water supply pipe and a heating return pipe; the refrigerant circulating system with the compressor is provided with the condenser, an evaporator, a reservoir, a throttle valve, an environment temperature sensor and a control device; and a water temperature sensor is arranged in the heat storage water tank. The heat pump water heater has a rational structure and high heating efficiency and is particularly suitable to be used in the northern regions with indoor heating devices.

Description

technical field [0001] The invention relates to a heat pump water heater, in particular to a heat pump water heater suitable for use in northern regions with indoor heating devices. Background technique [0002] Current domestic water heaters mainly include electric water heaters, gas water heaters, solar water heaters and heat pump water heaters. Electric water heaters are expensive to use and consume too much power; gas water heaters have high safety requirements and gas supply problems; although solar water heaters are low in use cost, they have high initial investment costs, occupy a large area of ​​the site, and are greatly affected by the weather. The disadvantage of long heating time; heat pump water heaters are being used more and more because of their advantages of high efficiency, energy saving, environmental protection and fast heating speed. However, heat pump water heaters are greatly affected by the ambient temperature. In northern regions where the ambient te...
