Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a solar photovoltaic and air source heat pump combined water heater, which has high adaptability to the environment, can be used in an environment with low ambient temperature, and can also improve the efficiency of the air source heat pump unit. The speed of hot water supply and the ability to store solar energy in the hot water storage tank at the same time solve the problem that the air source heat pump unit has regional characteristics in use. In winter when the temperature is low, only electric auxiliary heating can be used. Even the heat pump unit cannot operate due to the thick frost on the evaporator, and the heat exchange efficiency of the heat pump unit is low when the temperature is low, and it is impossible to quickly generate hot water for users.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a solar photovoltaic and air source heat pump combined water heater. Background technique [0002] As the name implies, the air source heat pump water heater is to transfer the heat in the air to the water through the refrigerant. The traditional electric water heater and gas water heater obtain heat energy by consuming gas and electric energy, while the air energy water heater heats water by absorbing the heat in the air. Purpose, in the case of consuming the same electric energy, it can absorb heat energy equivalent to about three times the electric energy to heat water. Large liquid storage tank, expansion valve, dry filter and four-way valve, through the traditional refrigeration components to realize the "reverse Carnot" principle, use the outdoor unit as a heat exchanger to absorb heat from the outdoor air and heat the low boiling point working medium ( Refrigerant) ...
