Abstract

The invention discloses a heat-pump water heater with an intelligent defrosting function. An exhaust port of a compressor (1) is communicated with input ends of a reversing valve (2), a condenser (3), a capillary tube (4) and an evaporator (5) in sequence; the output end of the evaporator (5) is connected with an air intake end II (16) of the reversing valve (2); a fan motor assembly (17) which is arranged at one side of the evaporator (5) is opposite to the evaporator (5); an air exhaust end II (18) of the reversing valve (2) is communicated with an output end of a gas-liquid separator (6), and an output end of the gas-liquid separator (6) is communicated with an air suction port of the compressor (1) through a connecting pipeline (9); a water supply pipeline system is connected to the condenser (3); an input pipe joint (11) is connected with a water intake end of the condenser (3) through a water pipe I (13), a water discharge end of the condenser (3) is connected with a water intake end of an auxiliary electric heater (10) through a water pipe II (14), and a water discharge end of the auxiliary electric heater (10) is connected with an output pipe joint (12) through a water pipe III (15); and a unit control device comprises a signal detection device and a main control board.

Description

technical field [0001] The invention relates to a heat pump water heater with intelligent defrosting function. Background technique [0002] In winter, when the ambient temperature is low, frost forms on the surface of the heat exchanger of the air source heat pump water heater, which affects the heat exchange. As the frost layer gradually thickens, the heat exchange will become less and less until it stops completely. Correspondingly, the temperature of the outlet water also drops significantly, so that it cannot be used. At present, the defrosting of air source heat pump water heaters usually relies on the reversing valve for reversing defrosting. The system structure is generally compressor, condenser, capillary tube, evaporator, reversing valve, fan, connecting copper pipes and electrical control parts , and its working process is: when the heat pump water heater is running in a low temperature environment and the surface of the evaporator is frosted, the microcomputer ...
