Description
Technical field
The utility model is related to field of air conditioning, is especially a kind of solar ejector refrigeration auxiliary air conditioner unit.
Background technology
Energy-conservation is always the important goal and R＆D direction of air conditioner industry, and the air-conditioning of drive energy is used as by the use of solar energy
Operating cost can be greatly lowered, so solar airconditioning always is the research and development focus in air conditioner industry.However, current
Three problems of solar airconditioning generally existing, one is to use solar energy completely, then needs to set the solar energy collecting dress of large area
Put, collection device cost is high, floor space is big；Two be heat pump performance by illumination conditionality, see that day is had a meal；Three be if it is desired to real
Existing reliable and stable operation, then must set up energy storage device, can further make complex system, further increase cost.
So, current solar airconditioning is often feasible in technical principle aspect, in actual promotion and application side
Face exists above-mentioned the problem of be difficult to overcome, it is difficult to obtain the accreditation in market, solar airconditioning has concept without market more like amusement.
And the heat pump air conditioner technology of electrically-driven compressors formula most conventional in field of air conditioning at present, be most ripe, technology most
Perfect, most widely used technology.Generally existing utilization rate of electrical is low, energy consumption for cooling is high again for above-mentioned electric driven compression formula air-conditioning,
Not enough save.
Utility model content
The technical problems to be solved in the utility model, which is to provide one kind, can improve utilization rate of electrical, reduction energy consumption for cooling, height
Imitate the solar ejector refrigeration auxiliary air conditioner unit of energy-conservation.
It is empty that technical solution of the present utility model is to provide a kind of solar ejector refrigeration auxiliary with following structure
Unit is adjusted, it includes the main frame cyclic system being in turn connected into by compressor, indoor heat exchanger, first throttle valve and outdoor heat exchanger
System；
A supplementary heat exchanger is additionally provided between first throttle valve and outdoor heat exchanger；
The unit also includes what is be made up of circulating pump, solar thermal collector, injector, Intermediate Heat Exchanger and second throttle
Solar energy auxiliary circulation system；
Circulating-pump outlet is connected with solar thermal collector entrance, and solar thermal collector outlet is connected with injector entrance, is sprayed
Emitter outlet is connected with Intermediate Heat Exchanger entrance, and Intermediate Heat Exchanger outlet is connected with pump entry, and Intermediate Heat Exchanger outlet is also
Connected with second throttle entrance, second throttle outlet is connected with supplementary heat exchanger entrance, supplementary heat exchanger outlet and injection
Device entrance is connected.
The utility model solar ejector refrigeration auxiliary air conditioner unit is analyzed with reference to operation principle compared with prior art
Advantage and progress.
The main frame circulatory system is circulated according to the route of compressor, outdoor heat exchanger, supplementary heat exchanger, indoor heat exchanger；And
In solar energy auxiliary circulation system, refrigerant, which is circulated, which is pumped into solar thermal collector, receive solar radiation is converted into high temperature height
Steam is pressed, into injector, by the La Geer nozzles formation high velocity air of injector, the refrigerant in supplementary heat exchanger is aspirated
Into injector, while maintaining the vacuum and low temperature in supplementary heat exchanger, cold is generated；Injector will be respectively from solar energy
After two strands of refrigerants mixing that heat collector and supplementary heat exchanger enter, exothermic condensation in Intermediate Heat Exchanger is entered with high pressure, from centre
A refrigerant part for heat exchanger discharge comes back to circulating pump, and another part enters in supplementary heat exchanger through second throttle to absorb heat
Evaporation, released cold quantity.And the cold of supplementary heat exchanger release, and absorbed by the main frame circulatory system, that is to say, that supplementary heat exchanger
Play a part of condensing in the main frame circulatory system or be subcooled, the refrigerant in the main frame circulatory system after outdoor heat exchanger heat release again
In supplementary heat exchanger heat release again, this just considerably reduces the high-pressure and condensation temperature of main frame refrigeration system, makes main frame
Compressor operating improves utilization rate of electrical in low pressure area, while having shared the part of compressor assembly using solar energy
Live load, so as to considerably reduce the energy consumption for cooling of air-conditioning, system energy consumption is reduced compared with Ordinary Compression air conditioner
30 ﹪, realize energy-conservation.Moreover, above-mentioned unit is not to fully rely on solar energy, so the collection device of large area need not be set,
Cost and floor space effectively are controlled, while without energy storage device is set, the cost of energy storage section will not be increased, sunlight is not
Also compressor cooling can be just often relyed on when good, without seeing that day is had a meal.Moreover, above-mentioned control method outdoor environment temperature compared with
When high, solar thermal collection system effect is preferable, ejector refrigeration effect is naturally also more preferable, therefore can reduce and outdoor heat exchanger is exchanged heat
Dependence, outdoor fan low wind shelves are run, the energy consumption of outdoor heat exchanger blower fan part is further saved.
