Description
Technical field
The utility model relates to the solar airconditioning system technical field, is the technology of cold and hot amount storage type solar airconditioning system specifically.
Background technology
Current, it is that solar heat drives the absorption type air-conditioner scheme that solar airconditioning mainly contains following know-why scheme, and main flow process principle is: solar energy-heat energy-refrigeration (heat)-air-conditioning.What have Typical Representative is the lithium bromide solar air-conditioner system.Utilize exactly solar heat collector to provide its generator needed heat medium water for Absorption Refrigerator.The temperature of heat medium water is higher, and the coefficient of performance of refrigeration machine (also claiming COP) is higher, and the refrigerating efficiency of air-conditioning system is also higher like this.Solar energy absorption type air conditioning system mainly consists of solar heat collector and Absorption Refrigerator two parts.1) absorption refrigeration operation principle: absorption refrigeration is to utilize the binary solution that two kinds of materials form to carry out as working medium.These two kinds of materials have different boiling points under same pressure, and wherein high boiling component is called absorbent, and lower boiling component is called cold-producing medium.Absorbent commonly used-cold-producing medium combination has two kinds: a kind of is lithium bromide-water, usually is applicable to Large Central Air Conditioning System; Another kind is water-ammonia, usually is applicable to minitype air conditioner.Absorption Refrigerator mainly is comprised of generator, condenser, evaporimeter and absorber.Take lithium-bromide absorption-type refrigerating machine as example.In the refrigerator operation process, be subject to the heat medium water heating in generator when lithium bromide water solution after, the water in solution is constantly vaporized; Steam enters condenser, after the water for cooling that is cooled, condenses; Along with the continuous vaporization of water, the solution concentration in generator constantly raises, and enters absorber; When the water in condenser enters evaporimeter by choke valve, rapid expansion and vaporizing, and in vaporescence a large amount of heats that absorb chilled water in evaporimeters, thereby reach the purpose of cooling refrigeration; In this process, the water at low temperature steam enters absorber, and the dense lithium-bromide solution be absorbed in device absorbs, and solution concentration progressively reduces, and by solution pumped back generator, completes whole circulation.2) solar energy absorption air conditioner operation principle: solar energy absorption type refrigeration utilizes solar heat collector to provide its generator needed heat medium water for Absorption Refrigerator exactly.Conventional absorption type air conditioning system mainly comprises several parts such as Absorption Refrigerator, air-conditioning box (or fan coil), boiler.And solar energy absorption type air conditioning system is to increase on this basis solar heat collector, storage tank and automatic control system again.In summer, at first the hot water heated by heat collector enter storage tank, when the hot water temperature reaches certain value, by storage tank, to refrigeration machine, provides heat medium water; Flow out the hot water of also having lowered the temperature from refrigeration machine and flow back to storage tank, then be heated into high-temperature-hot-water by heat collector; The chilled water that refrigeration machine produces leads to air-conditioning box, to reach the purpose of refrigeration air-conditioner.When solar energy is not enough to provide the high temperature heat medium water, can be by the donkey boiler additional heat.In the winter time, equally first the hot water of heat collector heating is entered to storage tank, when the hot water temperature reaches certain value, by storage tank, directly to air-conditioning box, provide hot water, to reach the purpose of heat supply heating.When solar energy can not meet the demands, also can be by the donkey boiler additional heat.In non-air-conditioning heating season, as long as the hot water of heat collector heating is directly led to the heat exchanger in storage tank for life, just the cold water in storage tank can be heated gradually for use.
