Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
The utility model discloses and utilize solar energy to give a kind of solar airconditioning HVAC system of air-conditioned room refrigerating and heat-supplying; Be illustrated in figure 1 as a preferred embodiment of the utility model; A kind of solar airconditioning HVAC system; Comprise the solar energy heating subsystem 1 that is used to heat, the absorption refrigeration unit 3 that is used to freeze and room air conditioner subsystem 4 and RACS 5, this air-conditioning HVAC system comprises that also two heat source high temp source pump 2 are used for complementary heating.This pair heat source high temp source pump 2 all has with RACS 5 with solar energy heating subsystem 1, absorption refrigeration unit 3, room air conditioner subsystem 4 and is connected.
The solar energy heating subsystem
Solar energy heating subsystem 1 mainly is made up of solar thermal collector 11, collector bracket, circulation line, circulating pump, valve, filter, heat storage water tank 12 etc.Solar thermal collector 11 has been realized bearing operation, ultralow temperature difference conduction, antiscale, antifreeze, leakproof, wind resistance function, through special processed, also can not leak even heat collector damages system, can move as usual.
The heat that solar thermal collector 11 is gathered is carrier with water, is stored in the heat storage water tank 12 through circulation line.The method of operation of the mounting means of heat storage water tank 12 and the high-order heat collector lower water box of solar thermal collector 11 employings and forced circulation, shutdown emptying realizes that the collection and the system of solar energy is antifreeze, has improved collecting efficiency and security of system to solar energy greatly.
Two heat source high temp source pump
The operation of solar air-conditioner system inevitably can receive the influence of weather conditions, and when solar energy can not satisfy the heat of system requirements, not enough heat energy was provided by two heat source high temp source pump 2.
Two heat source high temp source pump 2 mainly are made up of compressor, condenser, choke valve, air evaporator and five parts of water side evaporimeter.Cold-producing medium working medium is compressed into low-temp low-pressure gas the gas of HTHP under the effect of compressor.After high temperature and high pressure gas gets into condenser, with heat storage water tank in hot water carry out becoming liquid after the release heat in the heat exchanging process, hot water absorbs its heat and temperature constantly rises.Cold-producing medium liquefies it through choke valve more fully, and make liquid refrigerant respectively get into air evaporator and water side evaporimeter through valve regulated summer, while absorbing environmental air and be circulated throughout the heat of cold water from the indoor fan coil pipe; Then only get into air evaporator winter, the heat of absorbing environmental air makes the refrigerants vaporize evaporation to get into compressor again, so repeatedly circulation.
