Description
Technical field
The utility model relates to a kind of power saving refrigerator, is specially low-temperature cold store hot water defrosting energy saver.
Background technology
Temperature was low when low-temperature cold store was worked owing to its evaporation fan, ran to the easy frosting of some cycles evaporimeter and compressor surface, had a strong impact on refrigerating efficiency.Generally adding the device heating by electricity after the unit frosting defrosts, the time of defrosting generally needs 20 minutes to 60 minutes, thereby consume a large amount of electric energy, some freezer adopts Defrost now, but several freezers is dragged in the uncomfortable unification of Defrost, and compressor is still worked during the Defrost, and power consumption is still very big.
Summary of the invention
The utility model provides a kind of low-temperature cold store hot water defrosting energy saver of power and energy saving just at above technical problem.
Concrete technical scheme of the present utility model is as follows:
Low-temperature cold store hot water defrosting energy saver is made up of compressor, compressor outlet valve, magnetic valve, magnetic valve, air-cooled condenser, boiler condenser, reservoir, device for drying and filtering, water pump inlet valve, water pump, exit of pump valve, expansion valve, air-cooled evaporimeter, gas-liquid separator, compressor inlet valve, spray head, cooling-water temperature sensor, pressure sensor, outlet valve.Compressor links to each other with the compressor outlet valve, branch one is connected with the boiler condenser with magnetic valve then, branch two and magnetic valve be connected reservoir with branch one again after air-cooled condenser links to each other, reservoir links to each other with device for drying and filtering, device for drying and filtering is connected with expansion valve, expansion valve is connected with air-cooled evaporimeter, and air-cooled evaporimeter is connected with gas-liquid separator, and gas-liquid separator links to each other with compressor inlet valve.
The boiler condenser is connected with the water pump inlet valve, the water pump inlet valve is connected with the front end of water pump, the end of water pump is connected with the exit of pump valve, the exit of pump valve is connected with spray head, by hot water under the spray head spray air-cooled evaporimeter is defrosted, the water after the heat exchange turns back to the boiler condenser from outlet valve.
Technique effect of the present utility model shows: saved electric heater, the heat that adopts its condenser to produce adds hot water and carries out the hot water defrosting, has reached purpose of energy saving.
