Technical field
The utility model belongs to Application of Solar Energy field, particularly relates to a kind of photovoltaic slot type heating and refrigerating system.
Background technology
Solar energy (SolarEnergy), generally refers to the emittance of sunshine, and solar energy is a kind of regenerative resource, and sensu lato solar energy is the source of many energy on the earth, as wind energy, and biomass energy, potential energy of tide energy, water etc.The basic mode of Solar use can be divided into light-heat utilization, light-electricity utilization, light-chemical utilization, light-biological utilisation four class.In four class Solar use modes, the technology of light-hot-cast socket is the most ripe, and product is also maximum, advantage of lower cost.As: solar water heater, boiler, drier, solar cooker, solar energy greenhouse, solar energy housing, solar energy sea water desalination apparatus and solar heating and refrigerator etc.Solar light-heat power-generation is higher than the solar conversion efficiency of photovoltaic generation, but application is also not general.In photothermal deformation, current application is widest in area, technology is the most ripe, economy is it is preferred that the application of solar water heater.
But solar water heater only plays the effect of single heat supply, often when heat, need refrigeration, therefore need solar energy to utilize fully.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of and can freezes simultaneously and heat.
The utility model realizes like this, a kind of photovoltaic slot type heating and refrigerating system, this system comprises solar thermal collector, First Heat Exchanger, second heat exchanger, lithium bromide absorption type cooling and heating unit, cooling tower, water knockout drum and water collector, solar thermal collector has been arranged in parallel First Heat Exchanger and the second heat exchanger by pipeline, wherein, First Heat Exchanger is connected with lithium bromide absorption type cooling and heating unit for lithium bromide absorption type cooling and heating unit provides thermal source, lithium bromide absorption type cooling and heating unit connects cooling tower, the delivery outlet of lithium bromide absorption type cooling and heating unit is connected to the input channel interior supply user of water knockout drum, second heat exchanger is connected with the input channel of water knockout drum and supplies user, and the output channel of water collector is connected to the water inlet of the second heat exchanger and lithium bromide absorption type cooling and heating unit.
Further, be also disposed with the 3rd heat exchanger and storage tank between solar thermal collector and First Heat Exchanger, First Heat Exchanger and the hot water of the second heat exchanger directly and in storage tank carry out heat exchange.
Further, electric heater is set in water knockout drum.
Further, described solar thermal collector is the groove type solar optical collector being arranged on roof.
The utility model compared with prior art, beneficial effect is: this novel collection refrigeration and heating integral, and match with electrical heating, meet the needs that user is different, heat supply in winter operating mode, water absorbs heat in heat exchanger becomes high-temperature-hot-water, is transported to user's end, and the hot water of low temperature is reheated by being transported to heat exchanger.Directly the backwater returned from water collector is heated by heat exchanger from storage tank hot water out, enter again in water knockout drum after reaching design temperature (45 DEG C), supply user's heat demand.
At the cooling stages in summer, close the pipeline heated, send into the generator of lithium bromide absorption type cooling and heating unit from storage tank hot water out by the hot water that heat exchanger preparation temperature is 90 DEG C, heat the bromize lithium dilute solution extracted out from absorber, make it be condensed into concentrated solution, produce high temperature refrigerant vapour simultaneously.The high temperature refrigerant vapour that absorber produces enters condenser, and cooled water-cooled is congealed into water as refrigerant, and the heat tower that is cooled is taken away.Water as refrigerant enters evaporimeter, absorbs water as refrigerant heat and explosive evaporation, produces refrigerant vapour and enters absorber, and the concentrated solution be sent back in absorber absorbs.The temperature generated is that the chilled water of 7 DEG C sends into water knockout drum, for user's cooling needs.
