Preferably, the upper end of vaporization chamber is connected to the upper end of absorption chamber by first pipe.The density of steam is small,
So steam swims in upper end, first pipe, which to evaporate indoor steam, to be able to enter in absorption chamber.
Preferably, absorption chamber inner disc is wound with third heat-exchange tube, the cooling water in third heat-exchange tube passes through absorption chamber
Absorption chamber is exported after carrying out cold and hot exchange.Indoor dense lithium bromide is absorbed when absorbing steam, discharges heat, third heat-exchange tube
Interior cooling water can export higher temperature after carrying out cold and hot exchange, and the heat discharged in lithium bromide dilution is utilized from point
Amount.
Preferably, the lower end of absorption chamber is connected to the upper end that room occurs by second pipe, pacify on second pipe
Equipped with the first pump.Dilute lithium bromide of absorption chamber bottom is pumped to generation interior by the first pump.
Preferably, the lower end that room occurs is connected to the upper end of absorption chamber by third pipeline, pacify on third pipeline
Equipped with the second pump, the atomizer that quantity is at least one is installed in absorption chamber, atomizer is connected to third pipeline.It absorbs
The water in dilute lithium bromide is evaporated in room, to be condensed into dense lithium bromide, dense lithium bromide passes through in third pipeline to absorption chamber again
Secondary to be utilized, atomizer contacts dense lithium bromide with steam sufficiently.
Preferably, being equipped with third pump on the 4th pipeline, third pump is mounted between vacuum receiver and cryogen water tank.
The present invention is due to using above technical scheme, with significant technical effect:
The key point of traditional lithium bromide absorption type heat pump is outside present invention difference, the water as refrigerant of traditional lithium bromide heat pump
It is closed circuit circulatory system, it can not provide secondary steam to outside, waste this part energy.Cryogen of the invention
Water is the not circulatory system of opening a way, and therefore, heat pump absorbs 1 ton of water from vaporization chamber, so that it may from 1 ton of steam of room output occurs, make user
It can get the high-temperature steam for having utility value while obtaining refrigerating capacity.
The water as refrigerant of abandoning tradition of the present invention is recycled, and supplements water as refrigerant in vaporization chamber, in the supply port of water as refrigerant
Place's setting vacuum receiver, extracts the air being dissolved in water out, prevents supplement water from bringing oxygen into, influences the vacuum degree of unit.
Beneficial effect of the invention is: 1, reducing cooling cycle water；2, the discharge of waste heat is reduced；3, refrigerating capacity is obtained
Valuable heat is obtained simultaneously.
