Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] Such as figure 1 As shown, a preferred anti-frost air source heat pump system of the present invention includes a compressor 1, a liquid storage tank 5, a filter 4, an expansion valve 3, an evaporator 2, an air convection fan 11, a hot water storage tank 7, Solar collector 10. The evaporator 2 is provided with a first flow channel 20 for circulating refrigerant and a second flow channel 21 for circulating hot water.

[0021] Compressor 1, condenser 6, liquid storage tank 5, filter 4, expansion valve 3, evaporator 2, and compressor 1 are sequentially connected through pipelines to form a heating cycle, and the refrigerant absorbs and releases heat in the cycle hot. The high-pressure ref...

Abstract

The invention discloses an anti-frosting air source heat pump system which comprises an evaporator, a hot water storage tank and a solar thermal collector and further comprises a water pump and a water valve used for switchover between a large cyclic loop and a small cyclic loop. A first flow channel used for circulation of a refrigerating agent and a second flow channel used for circulation of hot water are arranged in the evaporator. The hot water storage tank, the water pump, the solar thermal collector, the water valve, the second flow channel and the hot water storage tank are sequentially communicated through water pipes so that the large cyclic loop can be formed; the hot water storage tank, the water pump, the solar thermal collector, the water valve and the hot water storage tank are sequentially communicated through water pipes so that the small cyclic loop can be formed. The system can solve the problem that frost is easily formed in a low-temperature environment, a compressor works within the optimal temperature range, the heating performance of a 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 anti-frost 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 efficiency and en...
