Abstract
The utility model discloses a high-temperature heat pump drying system, which comprises a refrigerant compressor. An air vent of the refrigerant compressor is in series connection with a venting sensor, a high pressure switch, a condenser, a liquid accumulator, a filter, a throttle expansion valve and a liquid inlet of an evaporator in sequence. An air restoring port of the refrigerant compressor is in series connection with an air-liquid separator, a low pressure switch and an air vent of the evaporator in sequence. The high-temperature heat pump drying system further comprises a high pressure energy regulating valve, an electromagnetic two-way valve and an air-liquid mixing head. A heat exchange fan is disposed outside the condenser, and a temperature sensor is connected to the evaporator. Because the physical principles that refrigerant liquid absorbs heat during evaporation and refrigerant gas gives out heat during condensation can be utilized in the structure, heat is absorbed from the air, and consumed electric energy is merely used for driving a motor. When an equal amount of electric energy is consumed, more heat is generated, and the amount of the heat is larger than that generated by a traditional electric heated tube by 3.8-4.5 times. Compared with a traditional drying system, the high-temperature heat pump drying system, electric energy or raw material expenses are saved, and additionally during an operation process, harmful substances such as waste water, waste gas and dust cannot be generated so that the purpose of being economical, energy-saving and environment-friendly is truly achieved.

Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structure principle chart of said utility model.
The specific embodiment
Referring to Fig. 1; A kind of high temperature heat pump drying system is provided; Comprise cold medium compressor 1; Its exhaust outlet 2 is contacted with inlet 10 orders of exhaust sensor 3, high-voltage switch gear 4, condenser 5, reservoir 6, filter 7, throttle expansion valve 8 and evaporimeter 9, and the exhaust outlet 14 of its return-air mouth 11 and gas-liquid separator 12, low tension switch 13 and evaporimeter 9 is polyphone in proper order, forms the closed circuit of cold-producing medium jointly.It also comprises high-pressure energy control valve 15, electromagnetism two-port valve 16 and gas-liquid mixing head 17, is provided with heat exchange blower fan 18 outside the said condenser 5, is connected with temperature sensor 19 on the evaporimeter 9.The inlet 20 of high-pressure energy control valve 15 links to each other with the liquid outlet 21 of reservoir 6, and the gas outlet 22 of high-pressure energy control valve 15 links to each other with the air inlet 23 of gas-liquid separator 12; The air inlet 24 of electromagnetism two-port valve 16 links to each other with pipeline between high-voltage switch gear 4 and the condenser 5, and the gas outlet 25 of electromagnetism two-port valve 16 links to each other with gas-liquid mixed 17; Gas-liquid mixed 17 is connected between the inlet 10 of throttle expansion valve 8 and evaporimeter 9.
The operation principle of the utility model is:
(1) cold medium compressor 1 energising work is compressed into the gas of HTHP with cold-producing medium, and sends into condenser 5 heat exchange, and electromagnetism two-port valve 16 is not worked at this moment.
(2) after the air cooling that the refrigerant gas of HTHP is blown into by the heat exchange blower fan in condenser; Heat is taken away the room air heat temperature raising by air; And cold-producing medium is cooled into high pressure low temperature liquid, arrives throttle expansion valve 8 throttling step-downs through reservoir 6, filter 7.
(3) refrigerant liquid of high pressure low temperature is in throttle expansion valve 8 after the throttling step-down; Become the gas-liquid two-phase body of low-temp low-pressure; Get into evaporimeter 9 gasifications and absorb heat energy in air from the inlet 10 of evaporimeter 9; Formed high-temperature low-pressure gas is got back to cold medium compressor 1 through gas-liquid separator 16, accomplishes the process that heats.
When the ratio that (4) detects condensing pressure and evaporating pressure when high-pressure energy control valve 15 surpasses default value, with after the part highly pressurised liquid gasification step-down, be directed at the muffler of cold medium compressor 1 automatically, reach the purpose of system capacity adjusting.
(5) when evaporimeter 9 with sensor 19 detect evaporimeter 9 surface temperatures and be lower than-1 ℃ and when continuously surpassing 10 minutes; 16 energisings of electromagnetism two-port valve are opened; The refrigerant gas of HTHP gets into the gas-liquid mixed that is attached thereto 17 through electromagnetism two-port valve 16, with hot gas and the mixing of gas-liquid two-phase mixture; Then get in the evaporimeter 9, utilize the heat that discharges that the white melting layer on evaporimeter 9 surfaces is removed; When evaporimeter 9 with sensor 19 when detecting evaporimeter 9 surface temperatures >=0 ℃, stop to 16 power supplies of electromagnetism two-port valve, electromagnetism two-port valve 16 cuts out, and accomplishes the process of defrosting.
The foregoing description is the preferred embodiment of the utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to the protection category of the utility model.
