The invention discloses an air energy water heater rapid defrosting device and method.The defrosting device comprises a refrigerant loop switching unit and a piezoelectric defrosting unit, and the refrigerant loop switching unit comprises an evaporator, a four-way valve, a gas-liquid separator, a compressor, a heat exchanger, a liquid storage tank, an expansion valve and a filter; wherein the four-way valve, the gas-liquid separator and the compressor are sequentially connected to form a closed loop; the four-way valve, the heat exchanger, the liquid storage tank, the expansion valve, the filter and the evaporator are sequentially connected to form a closed loop; the defrosting method comprises the following steps that the frosting degree is detected, and defrosting is controlled and executed. The efficiency of the air energy water heater and the use comfort of a user can be guaranteed, and the problems that the service life is greatly shortened and the reliability is greatly reduced due to the fact that the air energy water heater runs for a long time in the frosting state can be solved.
Description
technical field [0001] The invention relates to the field of air energy heat pumps, in particular to a rapid defrosting device and method for an air energy water heater. Background technique [0002] Because of its advantages of high efficiency, energy saving and environmental protection, air energy water heaters are widely used in hot water supply and indoor heating in winter for families, enterprises, institutions and residential buildings. However, during winter use, due to the low outdoor temperature, the copper tube of the evaporator heat exchange device will frost. [0003] Frosting is a serious problem faced by air-energy water heaters. On the one hand, it not only affects the performance of air-energy water heaters and user comfort; on the other hand, long-term operation of air-energy water heaters in the frosting state will greatly reduce their service life and reliability. . Therefore, fast and reliable defrosting of the air energy water heater is beneficial to i...
