detailed description

As shown in Figure 1, the utility model provides a novel waste heat utilization lithium bromide absorption refrigeration system, including a heat collection system 1, a generator 2, a heat exchanger 6, an absorber 5, a condenser 3 and an evaporator 4, and the generator The output end of 2 is connected with condenser 3, evaporator 4, absorber 5 and heat exchanger 6 in turn, and the output end of heat exchanger 6 is also connected with the injection end of generator 2 to form a loop. The injection end and the output end are also communicated with the heat collection system 1 respectively.

Wherein, a throttling valve 7 is installed on the pipeline between the condenser 3 and the evaporator 4 .

The circulation pipeline between the absorber 5 and the heat exchanger 6 is respectively installed with a circulation pump 8 and a solution pump 9, wherein the circulation pump 8 is installed on the output pipeline of the absorber, and the solution pump 9 is installed on the input pipeline of the absorber .

The working principle of the utility model is: use the heat collecting system to collect the waste heat of the equipment and pipelines in the main factory building to heat the circulating water, and provide the generator of the absorption refrigerating machine with the required hot coal water. In the generator, the refrigerant pair is heated by the hot coal water to vaporize the refrigerant vapor. The refrigerant vapor is cooled and condensed into a liquid in the condenser, and then enters the evaporator to absorb heat and evaporate through the throttle valve to produce a cooling effect. The refrigerant vapor produced by evaporation enters the absorber, is absorbed by the concentrated solution from the generator, and then is sent to the generator by the solution pump under pressure, and circulates in this way to obtain refrigeration capacity.

The above are only preferred embodiments of the present utility model, and are only illustrative rather than restrictive to the invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the invention, but all will fall within the protection scope of the present utility model.
