What at present, the heating in room was generally adopted is multiple modes such as fire coal, fuel oil, combustion gas, electric heating, heat pump and industrial exhaust heat.Wherein, cost is minimum, Energy Efficiency Ratio is the highest, the working service most convenient be exactly heat pump assembly.Utilize the heating combined equipment of heat pump techniques, can be divided into three major types: electric heat pump, gas turbine heat pump and absorption heat pump are arranged by drive principle.Wherein the Energy Efficiency Ratio with electric heat pump is the highest, uses also extensive.Electric heat pump is by the difference of its working method, can be divided into again: air-salt solution-water type heat pump, water-water type heat pump and water-multiple patterns such as air type heat pump, using now maximum at home is air-air type heat pump, air-water type heat pump and water-water type heat pump.Using maximum abroad is air-air type heat pump, water-water type heat and soil-water type heat pump.Air-air type heat pump wherein, working service is simple, cost is low, Energy Efficiency Ratio is high, the life-span is long, has obtained extensive use.But, the present air-air type heat pump of technology, because its Energy Efficiency Ratio is influenced by ambient temperature bigger, severe cold area especially, even can't operate as normal.Its range of application is very limited.And water-water type heat pump and soil-water type heat pump, their Energy Efficiency Ratio all is higher than air-air type heat pump.But the specification requirement of its O﹠M is than higher, install and supporting equipment also very complicated, expense is than higher.The high cost of itself in addition.Refrigeration, heating equipment that neither be very desirable.
Air-air type heat-pump apparatus is that present technology is the most ripe, most widely used general, cost is the cheapest, it is the simplest to safeguard, but the Energy Efficiency Ratio of its work is subjected to the influence of environment temperature very big.Usually can be in-5 ℃-40 ℃ environment operate as normal, as surpassing this temperature range, Energy Efficiency Ratio will descend greatly, even can not work.So it is operated in high temperature and extremely frigid zones, Energy Efficiency Ratio is very little.Water-water type heat pump assembly and soil-water type heat pump assembly is though overcome above-mentioned shortcoming.But geological state and underground hydrologic regime directly influence their performance, and from the angle of efficiency, energy-conservation, green, environmental protection, the heat pump assembly of above-mentioned pattern is not the direction of future development.
According to scientist's measuring and calculating, the annual solar radiant energy that arrives earth surface is about 130,000,000,000,000 tons of standard coals, promptly is about and present whole world year consumes 2 * 10 of various energy summations
4Doubly.Making full use of huge, inexhaustible, nexhaustible, the reproducible environmental protection new forms of energy-solar energy of energy, is that present technique will realize.With China Beijing area is example: be the biggest month of annual irradiation June, and average irradiation is 23.89MJ/m
2.d.Be the solar month of 30 days of annual irradiation December, and average irradiation is 10.14MJ/m
2.d.The average year irradiation is 6210.475MJ/m
2.d.If the solar thermal energy that this is huge absorbs efficiently, conversion efficiently stores efficiently again and utilizes, and its technical advantage and market prospects will be that present any refrigeration, heating equipment are incomparable.
Summary of the invention
The purpose of this utility model is to provide a kind of solar energy greenhouse heat pump refrigerating, heating combined equipment.It can be operated in-35 ℃ extremely frigid zones, and Energy Efficiency Ratio is still greater than 4 under heating mode.Under refrigeration mode, can be operated in 40 ℃ high temperature area, in output nominal cold, can also prepare hot water, and total Energy Efficiency Ratio can be greater than 6 greater than 50 ℃.
For achieving the above object, the utility model technical solution is finished like this: a kind of solar energy greenhouse heat pump refrigerating, heating combined equipment, it adopts compressor, pipeline by its compressor two ends is connected to four-way change-over valve respectively, be divided into two-way by four-way change-over valve: a route circulation line connects the energy storage case, is connected on an end of the heat exchanger that places solar energy greenhouse by expansion valve; Another circulation line of one route connects the energy storage case, and the other end that is connected to heat exchanger by circulation line constitutes.
Effect of the present utility model is: this device can be operated in-35 ℃ extremely frigid zones and 40 ℃ high temperature area, under heating mode, utilize the high-efficiency solar greenhouse, changed the operating mode of air-water type heat pump assembly condenser, can make whole device be operated in very desirable state, Energy Efficiency Ratio is up to more than 4.When working under refrigeration mode, heat pump not is to be discharged in the environment after the transfer of heat of refrigeration area is gone out, but utilizes cleverly again.Like this, total Energy Efficiency Ratio can greater than 6 and also the energy storage case in the cold that stores can export in many ways, form various cooling systems such as room refrigerating system low-temperature fresh-keeping system and freezer system, compared with prior art, install and use that cost is low, applied range and energy-conserving and environment-protective.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment is further described below in conjunction with accompanying drawing.By solar energy greenhouse heat pump refrigerating, heating combined equipment shown in Figure 1, it comprises a compressor 1, and the pipeline 2 and the pipeline 12 that are connected by compressor 1 two ends are connected to four-way change-over valve 3 respectively, by connecting the two-way circulation line on the four-way change-over valve 3; One road circulation line 4 is connected in energy storage casing 5, is connected on an end of the heat exchanger 7 that places solar energy greenhouse 8 by the expansion valve 6 that connects; Another circulation line 11 of one route is connected in energy storage case 10, and the other end that is connected to heat exchanger 7 by circulation line 9 constitutes.
