Problems solved by technology

[0003] When the existing second-type absorption heat pump unit is in use, the temperature difference between the inlet and outlet of the heated medium of the unit is relatively small. When dealing with the situation where the heated source has a large temperature difference, multiple second-type absorption heat pumps need to be connected in series. Disadvantages of complex operation

Embodiment Construction

[0015] Aiming at the technical problem of high investment cost when the second type of absorption heat pump is applied to the heated source with large temperature difference pointed out in the prior art, this paper conducts in-depth research. The study found that: the COP of the existing single second-type absorption heat pump is relatively low, usually 0.48 for a single-stage temperature increase, and 0.32 for a two-stage temperature increase. The so-called COP value is the energy efficiency ratio. The ratio of heating capacity to input heat.

[0016] That is to say, the key to reducing unit input cost is to increase the COP of the second type of absorption heat pump, aiming at how to increase the COP of the second type of absorption heat pump and reduce energy waste. In this paper, the second type of absorption heat pump in the prior art is studied in detail.

[0017] The second type of absorption heat pump in the prior art includes a generator, a condenser, an absorber and...

Abstract

The invention discloses a second-class absorption heat pump. The second-class absorption heat pump comprises a generator, a condenser, an absorber, a heat exchange module and an evaporator; the inlet of a heat exchange pipeline arranged inside the absorber communicates with an external driving heat source pipeline; the inlet of the heat exchange pipeline arranged inside the condenser communicates with a heated medium pipeline; a driving heat source flowing out of the absorber and a heated medium flowing out of the condenser have heat transfer by virtue of the heat exchange module; the energy for heating the heated medium in the heap pump comes from two parts, wherein the first part is heat energy generated by steam liquidation in the condenser, and the second part is the heat energy released when a concentrated solution in the absorber is diluted; namely the heat pump set disclosed by the invention can be used for recycling the energy released by steam liquidation in the condenser so as to heat the heated medium, so the COP of each set is greatly increased, the heated medium which is relatively low in temperature can be heated to a temperature higher than the temperature of the driving heat source, high temperature requirement of the heated medium and the use requirements on a large temperature difference environment for the inlet and the outlet can be satisfied, and thus energy waste rate is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of heat recovery, in particular to a second-type absorption heat pump. Background technique [0002] The second type of absorption heat pump is a kind of using a large number of medium and low temperature heat sources to generate a small amount of high temperature heat energy that can be used. That is, driven by high and low temperature heat energy, under the condition of low temperature cooling water, the heat produced is less than but higher than that of the medium and low temperature heat source, and part of the low-grade heat energy is transferred to high-grade heat energy, thereby improving the utilization rate of heat energy. [0003] When the existing second-type absorption heat pump unit is in use, the temperature difference between the inlet and outlet of the heated medium of the unit is relatively small. When dealing with the large temperature difference of the heated source, multiple second-type a...
