Description
Technical field
The utility model is related to field of air conditioning, is especially a kind of complementary air conditioner and heat pump unit of solar electrothermal.
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 again for above-mentioned electric driven compression formula air-conditioning, cooling and warming energy consumption
High, not enough energy-conservation, and during winter heating, the air-conditioning often easily frosting, once frosting, it is necessary to open defrosting mode in the winter time, is removed
It can not freeze during frost, influence Consumer's Experience.
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 cooling and warming energy
The solar electrothermal complementary air conditioner and heat pump unit of frosting is difficult when consumption, energy-efficient, winter refrigeration.
Technical solution of the present utility model is to provide a kind of complementary air-conditioning of solar electrothermal with following structure
Source pump, the main frame that it includes being in turn connected into by compressor, indoor heat exchanger, first throttle valve and outdoor heat exchanger is circulated
System,
A supplementary heat exchanger is additionally provided between first throttle valve and outdoor heat exchanger；
The unit is also included by circulating pump, solar thermal collector, triple valve, injector, Intermediate Heat Exchanger, the second throttling
The solar energy auxiliary circulation system that valve, the first magnetic valve and the second magnetic valve are constituted；
Circulating-pump outlet is connected with solar thermal collector entrance, and solar thermal collector outlet and the first valve port of triple valve connect
Logical, the second valve port of triple valve is connected with injector entrance, and injector outlet is connected with Intermediate Heat Exchanger entrance, Intermediate Heat Exchanger
Outlet is connected with pump entry, and the 3rd valve port of triple valve is connected with supplementary heat exchanger one end, same one end of supplementary heat exchanger
Also connected through the first magnetic valve with injector entrance；The other end of supplementary heat exchanger going out through second throttle and Intermediate Heat Exchanger
Mouth connection, the other end of supplementary heat exchanger is also connected through the second magnetic valve with pump entry.
The complementary air conditioner and heat pump unit of the utility model solar electrothermal and prior art phase are analyzed with reference to operation principle
The advantage of ratio and progress.
Referring initially to refrigeration mode, the main frame circulatory system is according to compressor, outdoor heat exchanger, supplementary heat exchanger, indoor heat exchanger
Route circulation；And in solar energy auxiliary circulation system, refrigerant, which is circulated, to be pumped into solar thermal collector, receives solar radiation
High temperature and high pressure steam is converted into, into injector, by the La Geer nozzles formation high velocity air of injector, by supplementary heat exchanger
In refrigerant be drawn into injector, while maintaining the vacuum and low temperature in supplementary heat exchanger, generate cold；Injector will
After the two strands of refrigerants mixing entered respectively from solar thermal collector and supplementary heat exchanger, heat release in Intermediate Heat Exchanger is entered with high pressure
Condensation, the refrigerant part discharged from Intermediate Heat Exchanger comes back to circulating pump, and another part enters through second throttle to be aided in
Absorb heat and evaporate in heat exchanger, released cold quantity.And the cold of supplementary heat exchanger release, and absorbed by the main frame circulatory system, that is,
Say, supplementary heat exchanger plays a part of condensing or is subcooled in the main frame circulatory system, and the refrigerant in the main frame circulatory system is in outdoor
Again in supplementary heat exchanger heat release again after heat exchanger heat release, this just considerably reduces the high-pressure of main frame refrigeration system and cold
Solidifying temperature, makes main frame compressor operating in low pressure area, improves utilization rate of electrical, while having shared compression using solar energy
The partial service load of machine system, so that the energy consumption for cooling of air-conditioning is considerably reduced, the system compared with Ordinary Compression air conditioner
Energy consumption reduces 30 ﹪, realizes energy-conservation.Moreover, above-mentioned unit is not to fully rely on solar energy, so large area need not be set
Collection device, effectively control cost and floor space, at the same without set energy storage device, energy storage section will not be increased
Cost, also can just often rely on compressor cooling when sunlight is bad, without seeing that day is had a meal.Moreover, above-mentioned control method is in room
When external environment temperature is higher, solar thermal collection system effect is preferable, ejector refrigeration effect is naturally also more preferable, therefore can reduce to room
The dependence of external heat exchanger heat exchange, the low wind shelves of outdoor fan are run, the energy consumption of outdoor heat exchanger blower fan part is further saved.
Heating mode is seen again, and the main frame circulatory system is according to compressor, indoor heat exchanger, supplementary heat exchanger, outdoor heat exchanger
Route circulation；And in solar energy auxiliary circulation system, refrigerant, which is circulated, to be pumped into solar thermal collector, receives solar radiation
High temperature and high pressure steam is converted into, supplementary heat exchanger exothermic condensation is entered, then circulating pump is returned to through the second magnetic valve；And aid in changing
Hot device liberated heat is absorbed by the refrigerant of the main frame circulatory system, improves the high-pressure of the main frame circulatory system, and enhancing heats effect
Really, while improving the low pressure of the main frame circulatory system, it is allowed to be not easy frosting；Moreover, having shared compressor using solar energy
The partial service load of system, so that the energy consumption that heats of air-conditioning is considerably reduced, it is energy-efficient；And the control method is carried
Go out, when outdoor environment temperature is higher, solar thermal collection system effect is preferable, the effect of supplementary heat exchanger heat release, therefore can
To reduce the dependence exchanged heat to outdoor heat exchanger, the low wind shelves of outdoor fan are run, outdoor heat exchanger blower fan portion is further saved
The energy consumption divided；Similarly, since above-mentioned unit is not to fully rely on solar energy, so the collection device of large area need not be set,
Without energy storage device is set, cost and floor space are effectively controlled, and is protected from weather influences, without seeing that day is had a meal.
