Background technology
Existing household refrigerating device substantially all adopts traditional vapor compression refrigeration system, compressor is driven by electric energy, low-pressure gaseous refrigerant is become by compressor compresses to enter condenser condenses behind the superheated steam of high pressure and become high pressure liquid refrigerant, again through entering the evaporator evaporation heat absorption after the expansion valve throttling, thereby finish a circulation, refrigeration system power comes from motor fully, the electric energy that this traditional motor-driven vapor compression refrigeration system consumes is more, especially in big and medium-sized cities, the peak of power consumption period in every summer, the high power consumption of refrigerating plant becomes the immediate cause of power supply shortage, and summer be sunshine the most sufficient the time, utilize the inning of solar energy just.It is cold-heat combined to use this device to realize simultaneously in the energy consumption that reduces refrigerating plant, for family provides the domestic hot-water and regulates indoor temperature and the required cold of storage food, significant for the day by day nervous current society of the energy.
Find through literature search prior art, number of patent application is to have proposed a kind of domestic solar central air-conditioning in 200420019167.4 the Chinese invention patent, this device has utilized the principle of absorption type refrigerating, adsorbent bed as " heat chemistry compressor ", is added condenser, evaporimeter and refrigeration system of capillary choke valve composition.The absorption that is replaced by adsorbent bed in this device, desorb drive cold-producing medium and finish a kind of refrigeration cycle in systems, thereby reach the purpose that produces refrigeration.But from present technical merit, because there is the low stability problem that reaches adsorbent bed of efficient in absorption type refrigerating itself, absorption type refrigerating also has a segment distance from practical application, " solar energy central air-conditioning " structure that proposes in this patent simultaneously is too complicated, and is unfavorable for cost control and stable operation.
Summary of the invention
For the defective and the deficiency that overcome prior art, the present invention has designed a kind of solar-auxiliary-driven cold-heat combined generator.Among the present invention, use booster pump to drive cold-producing medium and move in system, solar thermal collector then is used to produce the refrigerant vapour of HTHP, and whole apparatus structure is simple, cost is lower, stable.
The present invention is achieved through the following technical solutions, and the present invention includes booster pump, solar thermal collector, gas-liquid heat exchanger, attemperater, free convection air cooled condenser, expansion valve and evaporimeter.
The solar thermal collector outlet is connected with the import of gas-liquid heat exchanger, gas-liquid heat exchanger is arranged in the water tank, the outlet of gas-liquid heat exchanger is connected with the import of natural convection air-cooled condenser, the outlet of natural convection air-cooled condenser is connected with the import of expansion valve, the outlet of expansion valve is connected with the import of evaporimeter, the outlet of evaporimeter is connected with the import of booster pump, the supercharging delivery side of pump is connected with the import of solar thermal collector, and solar thermal collector inside has copper pipe the import of solar thermal collector is connected with outlet, the cold-heat combined system that so forms a sealing, fill cold-producing medium in the system, cold-producing medium can circulate in internal system.
After the present invention started, the refrigerant vapour in the booster pump suction evaporimeter was sent into the refrigerant vapour that has certain pressure in the solar thermal collector; Solar thermal collector absorbs the solar energy heating refrigerant vapour, and the pressure of refrigerant vapour and temperature are further improved, and produces the superheated refrigerant steam of HTHP; Under the driving of high pressure, superheated steam enters the gas-liquid heat exchanger in the attemperater, and the superheated steam of HTHP is with the water in the heat transferred water tank, and superheated steam is condensed into the cold-producing medium moist steam of temperature in the high pressure simultaneously; Warm cold-producing medium moist steam enters the free convection air cooled condenser subsequently, is cooled to the normal temperature high voltage refrigerant liquid by air; Refrigerant liquid is become the low-temperature refrigerant moist steam of gas-liquid two-phase by throttling through expansion valve; In evaporimeter, the refrigerant of low temperature moist steam absorbs sensible heat and a large amount of gasification latent heats, produces refrigeration.
The invention has the beneficial effects as follows in the parts of solar-auxiliary-driven cold-heat combined generator, to have only booster pump need consume a spot of electric energy, and device energy while output hot water and refrigeration have been saved the energy to greatest extent.Have remarkable economic efficiency and social benefit.

The specific embodiment
As shown in Figure 1, the present invention includes: solar thermal collector 1, water tank 2, gas-liquid heat exchanger 3, free convection air cooled condenser 4, expansion valve 5, evaporimeter 6 and booster pump 7.The solar-auxiliary-driven cold-heat combined generator system is formed in the connection of threading a pipe of above-mentioned parts.Solar thermal collector 1 operated by rotary motion is on the roof, and its outlet is connected by the import of pipeline with gas-liquid heat exchanger 3; Gas-liquid heat exchanger 3 is arranged in the water tank 2; The outlet of gas-liquid heat exchanger 3 is connected by the import of pipeline with natural convection air-cooled condenser 4; The outlet of natural convection air-cooled condenser 4 is connected by the import of pipeline with expansion valve 5; The outlet of expansion valve 5 is connected by the import of pipeline with evaporimeter 6, the outlet of evaporimeter 6 is connected by the import of pipeline with booster pump 7, the outlet of booster pump 7 is connected by the import of pipeline with solar thermal collector 1, so form the cold-heat combined system of a sealing, cold-producing medium can be circulated in internal system.
As shown in Figure 2, try hard to for cycling hot of the present invention.Device starts when sunshine is sufficient, and under the driving of booster pump 7, force value is low pressure P
2Refrigerant vapour is sucked out from evaporimeter 6, and obtains certain enthalpy and increase with pressure and increase; Refrigerant vapour enters in the pipeline of solar thermal collector 1 inside subsequently, because solar thermal collector 1 has absorbed a large amount of solar energy, its internal temperature values is higher, constantly absorbs heat in the flow process of refrigerant vapour in pipeline, and the enthalpy of refrigerant vapour and force value are increased to h rapidly
