Abstract
The utility model provides a heat pump water heater or a heat pump air conditioner, with defrosting function, which comprises a compressor, a condenser, a throttle device, and an evaporator, serially connected. The connecting tube between the compressor and the condenser is connected with a branch tube communicated with the inlet of the evaporator and mounted with a defrosting electromagnetic valve, and the tube between the outlet of the evaporator and the air return opening of the compressor is mounted with an electric heater. The utility model has the advantages that the utility model can supply energy for hot-air defrosting via the electric heater, to improve defrosting speed and resolve the defrosting defects of four-way valve. The utility model has simple structure, simple defrosting control, and stable system.
Description
Technical field
The utility model relates to a kind of Teat pump boiler or heat pump air conditioner with defrost function.
Technical background
Present Teat pump boiler or heat pump type air conditioner are when heating, and its evaporimeter can produce frosting inevitably, and along with the thickening of frost layer, the heat exchange function of its evaporimeter can obviously reduce, and need remove frost this moment.Yet present defrost mode is to flow to defrosting or the high-temperature exhaust air by compressor by the four-way change-over valve transformation working medium to carry out hot gas defrosting, the former advantage is that the defrosting energy is big, but need to consume the heat energy that has prepared, though and the latter does not consume the heat energy that has prepared, but because the power energy export-restriction of machine by compression of defrosting, defrosting power is little, and defrosting speed is slower.
Summary of the invention
The purpose of this utility model provides and a kind ofly can either the time not consume the heat energy that has prepared in defrosting, the Teat pump boiler with defrost function or the heat pump air conditioner of the problem that defrosting power is little in the time of can solving hot gas defrosting again.
The technical scheme that provides of the utility model is for achieving the above object: a kind of Teat pump boiler or heat pump air conditioner with defrost function, include compressor, condenser, throttling arrangement, evaporimeter, compressor, condenser, throttling arrangement, evaporimeter is cascaded successively, between the connecting pipe of compressor and condenser, be connected an arm, and the defrosting magnetic valve is housed on arm to evaporator inlet; In the middle of the pipeline between the return-air mouth of the outlet of evaporimeter and compressor, electric heater unit is housed.
When the utility model uses, Teat pump boiler or heat pump air conditioner are at the state of heating, the defrosting magnetic valve is in closed condition, when needs defrost, open electric heater unit, and open the defrosting magnetic valve, the high temperature and high pressure gas that allows compressor discharge enters evaporimeter and defrosts, allow then and enter electric heater unit absorption heat through the refrigeration working medium that is cooled behind the evaporimeter, return compressor again, finish a circulation, finish until defrosting so repeatedly, defrosting magnetic valve and electric heater unit are in closed condition again.
The utility model has the advantages that and can replenish the hot gas defrosting energy shortage by electric heater unit, improve the speed of hot gas defrosting greatly, can avoid the weak point of four-way valve defrosting again, simple in structure, defrosting control is simple, and system stability is reliable.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Present embodiment is by compressor 1, condenser 2, throttling arrangement 3, evaporimeter 4, compressor 1, condenser 2, throttling arrangement 3, evaporimeter 4 is cascaded successively, is connected an arm to evaporator inlet between the connecting pipe of compressor 1 and condenser 2, and defrosting magnetic valve 5 is housed on arm; In the middle of the pipeline between the return-air mouth of the outlet of evaporimeter 4 and compressor 1, electric heater unit 6 is housed.In the process that machine is moving, when evaporimeter frosting occurred and enters defrosting, compressor 1 need not to shut down, and directly opened defrosting magnetic valve 5, and the high temperature refrigeration working medium that allows compressor get rid of directly enters evaporimeter 4, starts electric heater unit 6 simultaneously.After defrosting finishes, close electric heater unit 6 and close defrosting magnetic valve 5 simultaneously.
