Abstract

The invention is a self-cascading air source heat pump water heater, which includes a compressor, a condenser, a water storage tank, a gas-liquid separator, an evaporation-condenser, a regenerator, an evaporator, a fan, a defrosting heater, two Throttle valve, seven temperature sensors, four controllers and two motors, the refrigerant pipeline connects the compressor, condenser, evaporator-condenser, regenerator, evaporator, and throttle valve to form a self-resetting The stacked air source heat pump circulates, and the condenser is installed in the water storage tank. In the present invention, the heat is provided by the air source, and the heat released by the condenser heats the water in the water storage tank through the circulation of the refrigerant. Because the present invention adopts the self-cascading heat pump cycle, it can work normally when the ambient air temperature is low, can supply heat around the clock, has good adaptability throughout the year, and has the advantages of simple structure and convenient installation. The invention can be widely applied to people's production and domestic water.

Description

technical field [0001] The invention belongs to the technical field of water heaters, in particular to a self-cascading air source heat pump water heater. Background technique [0002] The provision of domestic hot water throughout the year has become one of the important symbols of modern high-quality life. At present, traditional electric water heaters directly consume expensive high-quality electric energy, and the thermal efficiency will not exceed 100%, and there are safety hazards such as easy leakage. It meets the requirements of my country's energy policy and sustainable development strategy. Traditional solar water heaters mainly rely on electricity to heat hot water in cloudy, rainy, snowy weather and winter when there is insufficient sunshine, which consumes a lot of power and has poor safety. In addition, there are disadvantages such as poor balance of heating capacity and low utilization rate of the device throughout the year. The curre...
