Description

The defroster of air source hot pump water heater evaporimeter
Technical field
The present invention relates to a kind of defroster, particularly a kind of defroster of air source hot pump water heater evaporimeter.
Background technology
Air energy heat pump water heater is that the low-temperature heat quantity in air is absorbed, and is converted into high temperature heat with this to heat water temperature after compressor compresses.Heat-exchange working medium carries out heat absorption evaporation at evaporimeter, therefore easy in fin and evaporation tube frosting, and water heater needs to carry out defrosting work before running.Existing Defrost mode comprises employing cross valve reverse cycle defrost and compressor air-discharging defrosting, and cross valve reverse cycle defrost has good defrosting effect, and speed is fast, but causes water temperature to reduce because cold water flows into water tank, and experience is not good.Compressor air-discharging defrosting can not reduce water temperature, but defrosting time is long.Also the Defrost technology of mixing two kinds of patterns is had at present, but single unit system complex structure, require higher to control system.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of defroster of air source hot pump water heater evaporimeter, solves evaporimeter frosting problem.
Technical solution of the present invention is as follows: a kind of defroster of air source hot pump water heater evaporimeter, comprise bypass solenoid valve and compressor heat energy defroster, described bypass solenoid valve one end is arranged on the gas exhaust piping of the compressor of described air source hot pump water heater, the other end of bypass solenoid valve is arranged on the inlet tube of described evaporimeter, described compressor heat energy defroster comprises endothermic tube and defrosting pipe, described endothermic tube dish is located at described compressor case for absorbing compressor case heat, described defrosting pipe to be arranged in described evaporimeter and to be connected with the fin of evaporimeter, described endothermic tube and defrosting pipe are interconnected to constitute closed circulation, in described endothermic tube and defrosting pipe, thermal cycle working medium is set.
Preferably, described compressor is arranged on below described evaporimeter.
Preferably, described compressor and endothermic tube are arranged in casing, and described casing arranges heat-insulation layer.
Preferably, the connecting line of described endothermic tube and defrosting pipe arranges heat-insulation layer.
Preferably, described fin is provided with polytetrafluorethylecoatings coatings.
The advantage of technical scheme provided by the present invention is, compressor operating heat can be utilized to carry out pre-defrost to evaporimeter, then compressor air-discharging is utilized to carry out defrosting work, defrosting time is decreased compared to being exhausted merely defrosting, achieve the recycling of compressor heat energy, improve defrosting efficiency, reduce energy consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1, the defroster of the air source hot pump water heater evaporimeter of the present embodiment comprises bypass solenoid valve 1 and compressor heat energy defroster.Bypass solenoid valve 1 one end is arranged on the gas exhaust piping 3 of the compressor 2 of air source hot pump water heater, and the other end of bypass solenoid valve 1 is arranged on the inlet tube 5 of evaporimeter 4.This part constitutes compressor air-discharging defroster, and the high-temperature exhaust air that make use of compressor 2 enters evaporimeter 4 and improves the defrosting of fin 6 temperature.Compressor heat energy defroster comprises endothermic tube 7 and defrosting pipe 8, and endothermic tube 7 dish is located at compressor 2 shell for absorbing compressor 2 shell heat; Compressor 2 with endothermic tube 7 is whole to be arranged on one and to have in the casing 9 of heat-insulation layer, and is arranged on below evaporimeter 4.Defrosting pipe 8 to be arranged in evaporimeter 4 and to be connected with the fin 6 of evaporimeter 4, endothermic tube 7 and defrosting pipe 8 are interconnected to constitute closed circulation, in endothermic tube 7 and defrosting pipe 8, thermal cycle working medium is set, the connecting line of endothermic tube 7 and defrosting pipe 8 arranges heat-insulation layer, and fin 6 is provided with polytetrafluorethylecoatings coatings.Produce heat when compressor 2 works to be absorbed by endothermic tube 7, the heat release in defrosting pipe 8 of thermal cycle working medium, to fin 6 preheating defrosting, opens bypass solenoid valve 1 after a period of time, compressor 2 exhaust is entered evaporimeter 4 and is exhausted defrosting.
