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 the vacuum receiver for sloughing air in water on the 4th pipeline.In the supplement of water as refrigerant Vacuum receiver is set at mouthful, extracts the air being dissolved in water out, prevents supplement water from bringing oxygen into, influences the vacuum degree of unit.
Preferably, being equipped with third pump on the 4th pipeline, third pump is mounted between vacuum receiver and cryogen water tank.
The utility model is due to using above technical scheme, with significant technical effect:
The key point of the outer traditional lithium bromide absorption type heat pump of the utility model difference is, traditional lithium bromide heat pump it is cold Agent water is closed circuit circulatory system, it can not provide secondary steam to outside, wastes this part energy.This is practical new The water as refrigerant of type 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 be steamed from occurring 1 ton of room output Vapour can get the high-temperature steam for having utility value while so that user is obtained refrigerating capacity.
The water as refrigerant of the utility model abandoning tradition is recycled, and supplements water as refrigerant in vaporization chamber, in the benefit of water as refrigerant Setting vacuum receiver at mouth is filled, extracts the air being dissolved in water out, prevents supplement water from bringing oxygen into, influences the vacuum of unit Degree.
The beneficial effect of the utility model is: 1, reducing cooling cycle water；2, the discharge of waste heat is reduced；3, freezed Valuable heat is obtained while amount.
