Abstract

The invention discloses an air energy water heater capable of achieving rapid defrosting and stable water temperature and a using method.The air energy water heater comprises a refrigerant loop, a water control loop and a frequency conversion controller, the structures and pipe network layout of the refrigerant loop and the water control loop are simpler, switching control over working modes is convenient, the functions are comprehensive, and the water temperature is stable. The switching control of circulating heating, return water heating and constant-temperature and constant-pressure water supply can be realized only by controlling the four-way valve, so that the simplicity of the control system is realized, and the stability of water supply temperature and pressure can be effectively improved on the basis of greatly simplifying the system structure, hardware cost and energy consumption cost. According to the method, whether the copper pipe is frosted or not and the frosting degree can be accurately and reliably predicted, and a basis is provided for optimization control of subsequent defrosting. Vibration defrosting, thermal expansion defrosting and hot defrosting are organically combined, the defrosting effect can be effectively improved, the defrosting process is accelerated, and the overall performance of the air energy water heater is improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an air-energy water heater capable of realizing rapid defrosting and stable water temperature and a use method thereof. 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. Frosting is a serious problem faced by air-energy water heaters. It not only affects the performance of air-energy water heaters and user comfort, but also the long-term operation of air-energy water heaters in the frosting state will greatly reduce the life and reliability of air-energy water heaters. Quickly and accurately judging whether the air-energy...
