Abstract

The invention discloses an energy-saving and frost-proof air-source heat pump system. The energy-saving and frost-proof air-source heat pump system comprises an evaporator, a hot water storage tank, a solar energy collector, a water pump and a thermostat assembly, wherein a first flow channel for circulating refrigerants and a second flow channel for circulating hot water are arranged in the evaporator; the hot water storage tank, the water pump, the solar energy collector, the thermostat assembly, the second flow channel and the hot water storage tank are sequentially connected with one another through water pipes to form a large circulation loop; the hot water storage tank, the water pump, the solar energy collector, the thermostat assembly and the hot water storage tank are sequentially connected with one another through water pipes to form a small circulation loop; and the thermostat assembly automatically adjusts the amount of water in the large circulation loop and the small circulation loop. By the energy-saving and frost-proof air-source heat pump system, the problem that frost is prone to occur in low temperature environments is solved, a compressor can operate in an optimal temperature range, heating performance of the heat pump is improved, and power consumption of the compressor is reduced.

Description

technical field

[0001] The invention relates to the field of heat pump water heaters, in particular to an energy-saving frost-proof air source heat pump system. Background technique

[0002] Air source water heaters, also known as heat pump water heaters, or air energy water heaters, are heat transfer devices that use refrigeration principles to absorb heat from the air to create hot water. The compressor, condenser, expansion valve, evaporator, and compressor are connected sequentially through pipelines to form a circulation loop. Refrigerant flows in the pipeline. By allowing the refrigerant to continuously evaporate (the evaporator absorbs heat from the environment) - compression - condensation (the condenser releases heat) - throttling (throttling through the expansion valve) - reevaporation (the evaporator absorbs heat from the environment) The thermodynamic cycle process, thus bringing the heat from the environment to the water. It has the characteristics of high ef...
