In lithium bromide absorption chiller system, because the boiling point of lithium bromide water solution own is very high, extremely difficult volatilization is so can think that the steam on the lithium bromide saturated solution liquid level is pure water steam; At a certain temperature, the steam-laden partial pressure on the lithium bromide water solution liquid level is less than the saturated partial pressure of pure water; And concentration is higher, and the steam-laden partial pressure on the liquid level is less.So under identical temperature conditions, lithium bromide water solution concentration is larger, its ability that absorbs moisture is just stronger.So adopt lithium bromide as absorbent, water is as cold-producing medium.In the lithium bromide absorption chiller system running, in generator 32, be subject to the heating of heat medium water (being the high-temperature water that solar module produces) when lithium bromide water solution after, water in the solution is constantly vaporized, continuous vaporization along with water, lithium bromide water solution concentration in the generator 32 constantly raises, and enter absorber 35, and water vapour enters condenser 25, come to condense after the water quench of self-cooling water tank 2, become the aqueous water of high pressure low temperature.When the high pressure low temperature aqueous water in the condenser enters evaporator 27 by choke valve 26, rapid expansion and vaporizing, and in vaporescence a large amount of heats that absorb evaporator 27 interior chilled waters (being the cold water that the refrigeration plant such as air-conditioning needs), thereby reach the purpose of cooling refrigeration.Simultaneously, the water at low temperature steam enters absorber 35 and is absorbed by lithium bromide water solution, and solution concentration progressively reduces, and sends generator 32 back to by circulating pump 34 again, finishes whole circulation.So move in endless cycles, produce continuously cold.Because bromize lithium dilute solution is cooled in absorber 35, temperature is lower, in order to save the heat of heat dilute solution, improve the heat efficiency of whole system, between generator 32 and absorber 35, also be provided with heat exchanger 33, the high temperature concentrated solution of generator 32 outflows and the low temperature weak solution of absorber 35 outflows are carried out heat exchange, improve the temperature that weak solution enters generator.
