Abstract

The invention provides a heating hot water heat pump unit for efficiently recovering industrial waste heat. According to the heat pump unit, two circulating working mediums are adopted inside to achieve internal exchange of a refrigerant, and a compressor is simultaneously used for improving the solution absorption effect of an absorber, wherein the compressor adopts a multi-stage blade mode. Compared with the heat pump technology in the prior art, the heating temperature can be greatly improved, the industrial waste heat can be fully recovered, and the heat pump unit has the obvious technicaladvantages of energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a heat pump technology for recovering industrial waste heat for raising the temperature of hot water. Background technique [0002] There is a wide range of heat exchange processes in the field of energy utilization, and the heat transfer process can be summarized as transfer from high-temperature fluid to low-temperature fluid or from low-temperature fluid to high-temperature fluid. According to Newton's second law, heat can be spontaneously transferred from a high-temperature object to a low-temperature object, and it can be realized only by using an ordinary heat exchanger; A large amount of high-grade energy, such as electricity, high-temperature steam or hot water, requires the use of heat pumps, ejectors, etc. In the prior art, the use of heat pump technology has been recognized and applied by the market due to its high efficiency and reliability.
