Abstract

The invention discloses a household wall-mounted flat solar heat-pump water heater and a control method thereof. The household wall-mounted flat solar heat-pump water heater comprises an outdoor unit and an indoor unit, wherein the outdoor unit comprises a tube-wing heat collecting evaporator, a solar heat-pump compressor, a thermal expansion valve, a liquid storage device, a dry filter and an electromagnetic valve, wherein the tube-wing heat collecting evaporator is formed through integrating a heat collecting plate core of a flat solar heat collecting panel and an evaporator of a heat pump; the indoor unit comprises a controller, a heat-storage water tank and a coil tube type condenser which is arranged inside the heat-storage water tank; the operation of the flat solar heat-pump water heater is realized through controlling the compressor, the thermal expansion valve and the electromagnetic valve by the controller. Through the manner, the household wall-mounted flat solar heat-pump water heater has the advantages that various complicated, changeable and harsh working conditions of a solar heat collecting evaporator are overcome successfully, heat pump technologies can be applied to solar heat utilization, the efficiency is increased greatly compared with that of a solar water heater and that of an air source heat-pump water heater, and meanwhile, the problems that the flat solar water heater needs to be protected from frostbite in winter and the air source heat-pump water heater needs to be defrosted in winter are solved.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization and heat pump system design and manufacture, in particular to a household wall-mounted flat solar heat pump water heater and a control method thereof. Background technique [0002] The only way for solar water heaters to enter the city is to install split wall-mounted solar water heaters like installing split air source heat pump water heaters. The technical route for its specific implementation is to install solar heat collector panels on the south-facing facades of buildings (such as balconies, walls, sunshades, etc.), install heat storage tanks indoors, and arrange heat collector plates and heat storage tanks. Heat collection circulation pipeline. [0003] The installation of solar thermal collectors on the facade of a building must be perfectly integrated with the building, that is, to meet the requirements of building integration. Among the many thermal collectors, flat solar ...
