Abstract
The utility model relates to an air source heat pump energy storage defrosting system, which belongs to the technical field of refrigerating, and comprises a compressor, a defrosting heater, a water condenser, a throttle device, an air cooling evaporator, heat storage agents, defrosting liquid, a defrosting liquid ascending tube, a defrosting tube, a control valve, an energy storage heating tube and a connection tube system. The energy storage heating tube and the defrosting heater of a heat pump system are vertically fixed inside the defrosting heater; a defrosting liquid tank is installed on the top portion of the defrosting heater; and an outlet of the control valve is communicated with an inlet of the lower portion of the defrosting liquid ascending tube through a connection tube at the bottom portion of the defrosting heater. The control valve can be automatically opened when receiving defrosting instruction, and the defrosting liquid flows through the defrosting tube to automatically remove frost on the evaporator.
Description
Technical field:
The utility model relates to a kind of air source heat pump accumulation of energy defrosting system, belongs to refrigeration technology field.It is made up of compressor, Defrost heater, water cooled condenser, throttling arrangement, air-cooled evaporimeter, heat-storage agent, defrosting liquid, defrosting liquid tedge, defrosting flow container, defrosting pipe, control valve, accumulation of energy heating tube and connecting tube system.Receiving defrosting when instruction when control valve can open automatically, defrosting liquid just flow through vaporizer side defrosting pipe and remove frost on the evaporimeter automatically.
Background technology:
The evaporimeter of the air-cooled heat pump that generally uses winter all can be because of solid wall temperature be lower than the zero degree frosting now, if do not defrost immediately, and then frost can cumulative its operate as normal that has a strong impact on.The defrosting measure of air-cooled heat pump evaporimeter now mainly contains electric defrosting and the contrary operation defrosting of heat pump two classes, and the former expends more energy because of using accessory power supply, is unfavorable for energy-conservation and environmental protection; And the latter changes the operation of heat pump system into the refrigeration modes operation with transfer valve, and this not only makes system's operation complicated, makes operation of heat pump discontinuous again, can greatly reduce the service efficiency of equipment.
Summary of the invention:
In order to remedy above-mentioned the deficiencies in the prior art, the utility model will provide a kind of not to be stopped the normal operation of heat pump and can utilize the independent hot gas defrosting condenser in parallel with the air-cooled condenser of heat pump to realize the defrosting of evaporator with heat pump.It comprises compressor 1, Defrost heater 2, water cooled condenser 3, throttling arrangement 4, air-cooled evaporimeter 5, heat-storage agent 6, defrosting liquid 7, defrosting liquid tedge 8, defrosting flow container 9, defrosting pipe 10, control valve 11, accumulation of energy heating tube 12, when heat pump compressor is worked, Working medium gas warp let-off accumulation of energy heating tube 12, water cooled condenser 3, throttling arrangement 4, the air-cooled evaporimeter 5 of HTHP are got back to the suction port of compressor again, and accumulation of energy this moment heating tube 12 is melted into liquid with the solid-state heat-storage agent 6 in the Defrost heater 2 heat is stored.Frosting thickens just and sends the defrosting signal to control valve 11 on the tight device of evaporation, control valve 11 is opened immediately, density decline and upwards mobile after placing Defrost heater 2 interior defrosting liquid tedges 8 to be heated, defrosting pipe 10 interior defrosting liquid 7 just flow downward after white layer of heat release defrosting of evaporimeter and finish accumulation of heat defrosting circulation through control valve 11.
Description of drawings:
Accompanying drawing 1 is air source heat pump accumulation of energy defrosting system figure.
Wherein: the 1--compressor; The 2--Defrost heater; The 3--water cooled condenser; The 4--throttling arrangement; The air-cooled evaporimeter of 5--; The 6--heat-storage agent; The 7--liquid that defrosts; 8--defrosting liquid tedge; The 9--flow container that defrosts; 10--defrosting pipe 11--control valve; 12-accumulation of energy heating tube.
When heat pump compressor 1 work, Working medium gas warp let-off accumulation of energy heating tube 12, water cooled condenser 3, throttling arrangement 4, the wind-cooled evaporator 5 of HTHP are got back to again the suction port of compressor, accumulation of energy this moment heating tube 12 is melted into liquid with the solid-state heat-storage agent 6 in the Defrost heater 2, and heat is stored. Frosting thickens just and sends the defrosting signal to control valve 11 on evaporimeter, control valve 11 is opened immediately, place defrosting liquid tedges 8 in the Defrost heater 2 rear density of being heated to descend and upwards flow, the defrosting liquid 7 in the defrosting pipe 10 is after the defrosting of wind-cooled evaporator frost layer heat release and flow downward and finish accumulation of heat defrosting circulation through control valve 11.
The specific embodiment:
Fig. 1 also is 5kW air source heat pump accumulation of energy defrosting system figure.
When heat pump compressor is worked, Working medium gas warp let-off accumulation of energy heating tube 12, water cooled condenser 3, throttling arrangement 4, the air-cooled evaporimeter 5 of HTHP are got back to the suction port of compressor again, and accumulation of energy this moment heating tube 12 is melted into liquid with the solid-state heat-storage agent 6 in the Defrost heater 2 heat is stored.Frosting thickens on air-cooled evaporimeter 5, just send the defrosting signal to control valve 11, control valve 11 is opened immediately, after placing Defrost heater 2 interior defrosting liquid tedges 8 to be heated, defrosting liquid 7 density in the pipe descend and upwards flow, defrosting liquid 7 in the defrosting pipe 10 just flows downward and finishes the accumulation of heat defrosting through control valve 11 and circulate after the defrosting of evaporimeter frost layer heat release.
