Abstract

The invention relates to an auto-cascade air source heat pump water heater which comprises a compressor, a condenser, a water storage tank, a gas-liquid separator, an evaporation-condensing apparatus, a heat regenerator, an evaporator, a fan, a defrosting heater, two throttling valves, seven temperature sensors, four controllers and two electromotors, wherein a refrigerant line connects the compressor, condenser, evaporation-condensing apparatus, heat regenerator, evaporator and throttling valves together to constitute an auto-cascade air source heat pump circulation; and the condenser is installed in the water storage tank. The heat energy of the auto-cascade air source heat pump water heater is supplied by an air source; and water in the water storage tank is heated by the heat energy released by the condenser; the water storage tank adopts a thermal-insulation material for thermal insulation; and the top is provided with an air pressure balance pipe. Due to the adoption of the auto-cascade heat pump circulation, the auto-cascade air source heat pump water heater can work normally when the ambient air temperature is lower, can supply heat in all kinds of weather, has favorable adaptability all the year around, has the advantages of simple structure and the like, and is convenient to install. The auto-cascade air source heat pump water heater can be widely suitable for production and domestic water of people.

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 current single-cycle air source...
