Generally traditional air source heat pump dehydrator is common single-stage heat pump。In actual application, by drying, temperature requirement is higher, for using in the environment relatively low in use ambient temperature, may result in the compression ratio of the heat pump of whole dehydrator too big, considerably beyond the compression ratio that system can be born, heating effect is also very poor simultaneously。
Utility model content
Technical problem to be solved in the utility model is how to reduce the compression ratio of dehydrator in relatively low environment, it is provided that overall heating effect。
In order to solve above-mentioned technical problem, this utility model devises a kind of cascade type heat pump dehydrator, it is characterized in that the heating system of dehydrator comprises hot pump in low temp system and high temperature heat pump system simultaneously, the air vent of the low-temp. portion partial compression machine of hot pump in low temp system is connected with the evaporative condenser of high temperature heat pump system, the evaporative condenser offer work thermal source that the pressure high temperature hot gas of low-temp. portion partial compression machine output is high temperature heat pump system。
Described cascade type heat pump dehydrator, it is characterised in that described low-temp. portion partial compression machine is DC frequency-changeable compressor。
Described cascade type heat pump dehydrator, it is characterised in that described hot pump in low temp system is provided with defrosting electromagnetic valve, described defrosting electromagnetic valve is arranged on low temperature partial vaporiser and is connected with the air vent of low-temp. portion partial compression machine。
Implement this utility model and have the advantages that absorbing heat under very low ambient temperature by cryogenic system dries releasing heat at the temperature of side in significantly high use simultaneously。The respective operation compression of high/low temperature refrigeration system is smaller, and operating condition is stable, and Energy Efficiency Ratio is high。

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
Fig. 1 is cascade type heat pump dryer system block diagram, including low temperature part evaporator fan 1, low-temp. portion partial compression machine 2, low temperature partial vaporiser 3, low temperature part gas-liquid separator 4, low temperature part defrosting electromagnetic valve 5, low temperature partial throttling device 6, low temperature part fluid reservoir 7, evaporative condenser 8, high-temperature part gas-liquid separator 9, high-temperature part compressor 10, high-temperature part throttling arrangement 11, high-temperature part fluid reservoir 12, high-temperature part condenser fan 13, the low-temperature refrigerant of high-temperature part condenser 14 and connecting copper pipe and internal system thereof and high temperature refrigerant pressure composition。
Hot pump in low temp system operation principle is as follows:
Cryogenic compressor 2 is compressed in the low temperature refrigerant gas entrance evaporative condenser 8 of High Temperature High Pressure after being sucked by the low-temperature refrigerant of gaseous state low-temp low-pressure and carries out heat release, the low-temperature refrigerant liquid being condensed into high pressure carries out reducing pressure by regulating flow by low temperature partial throttling device 6 after low temperature part fluid reservoir 7, become the low-temperature refrigerant gas-liquid mixture of low-temp low-pressure, then passing through low temperature partial vaporiser 3 and be evaporated heat absorption, the gaseous state low-temperature refrigerant becoming low-temp low-pressure continues this cycle of operation by returning to after low temperature part gas-liquid separator 4 in cryogenic compressor 2。Whole cryogenic system absorbs heat endlessly from air, and rejects heat to evaporative condenser 8, provides thermal source for high-temperature systems work。
Wherein cryogenic system adopts DC frequency-changing refrigeration system, cryogenic compressor 2 adopts DC frequency-changeable compressor, the FREQUENCY CONTROL of whole system is by outside environment and uses the drying thermic load of side to be adjusted, thus preventing from causing whole system fluctuation of service because the load of high and low pressure system does not mate or breaking down。
The defrosting of cryogenic system adopts hot gas bypass defrosting technology, when cryogenic system reaches defrosting condition, low temperature part defrosting electromagnetic valve 5 is opened, and the low temperature refrigerant gas of High Temperature High Pressure directly enters into low temperature partial vaporiser 3 from the air vent of cryogenic compressor 2 and carries out defrost。This defrosting formal system steady operation, does not interfere with the properly functioning of high-temperature systems。
High temperature heat pump system operation principle is as follows:
High temperature compressor 10 is compressed in the high temperature refrigerant gas entrance high-temperature part condenser 14 of High Temperature High Pressure after being sucked by the high temperature refrigerant of gaseous state low-temp low-pressure and carries out heat release, the temperature refrigerant liquid being condensed into high pressure carries out reducing pressure by regulating flow by high-temperature part throttling arrangement 11 after high-temperature part fluid reservoir 12, become the high temperature refrigerant gas-liquid mixture of low-temp low-pressure, then pass through entrance evaporative condenser 8 and be evaporated heat absorption, the gaseous state high temperature refrigerant becoming low-temp low-pressure continues this cycle of operation by returning to after high-temperature part gas-liquid separator 9 in high temperature compressor 10。Whole high-temperature systems absorbs, by evaporative condenser 8, the heat discharged in cryogenic system, and is discharged in baking room by heat by high-temperature part condenser 14, heating, drying medium endlessly。
Under very low ambient temperature, absorb heat by cryogenic system and dry releasing heat at the temperature of side in significantly high use simultaneously。The respective operation compression of high/low temperature refrigeration system is smaller, and operating condition is stable, and Energy Efficiency Ratio is high, thus saving the energy that baking needed is wanted to greatest extent。
Above disclosed it is only this utility model one embodiment, certainly the interest field of this utility model can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that this utility model claim is made, still fall within the scope that utility model contains。
