Backheating type absorption-generation system and backheating type first class absorption heat pump

Abstract

The invention provides a backheating type absorption-generation system and a backheating type first class absorption heat pump, belonging to the technical field of heat pump / refrigeration.The backheating type absorption-generation system consists of a first absorber, a second absorber, a generator, a first solution pump, a second solution pump, a solution heat exchanger and a steam bleeding chamber, wherein the first absorber is communicated with the second absorber through the second solution pump, the second absorber is communicated with the generator by a first solution pump and the solution heat exchanger, the generator is connected with the steam bleeding chamber by the solution heat exchanger and the second absorber, the steam bleeding chamber is communicated with the first absorber by a solution pipe; the first absorber is provided with a pipe for heated medium and a refrigerant steam channel which are respectively connected with the exterior; externally, a refrigerant pipe is communicated with the first absorber and then the first absorber is connected with the second absorber by the refrigerant steam channel; the steam bleeding chamber is communicated with the first absorber by the refrigerant steam channel, the generator is connected with the exterior by a driving thermal medium pipe and the refrigerant steam channel; a condenser and a evaporator and other components form a serial backheating type first class absorption heat pump, so that uninterrupted engagement of the first class absorption heat pump in terms of working parameter and performance index is realized.

Description

Technical field: [0001] The invention belongs to the technical field of refrigeration and low-temperature waste heat utilization heat pump. Background technique: [0002] The premise of using absorption heat pump technology for waste heat utilization is that the heat pump can raise the heat from the waste heat temperature to a temperature above the user's demand, and at the same time make the performance index of the absorption heat pump unit as high as possible; Under the premise of the demand, the refrigeration efficiency of the driving heat medium should be maximized as much as possible. This requires that the corresponding unit used has a reasonable structure and working process, and also requires an absorption heat pump with a corresponding high performance index in different working parameter ranges. [0003] In order to improve the heating temperature and performance index of the first type of absorption heat pump, people first obtained units with different effects a...
