Abstract

The invention provides a normal-pressure absorber and an absorption heat pump system comprising the same. The absorber comprises a membrane module. The membrane module comprises membrane materials which have permselectivity on vapor of diluents. The diluents flow on one side of the membrane materials. Heating media flow on the other side of the membrane materials. The membrane materials comprise air gaps. The equilibrium vapor pressure of the heating media on one side of the membrane materials is lower than the vapor pressure of the surface of the diluents on the other side of the membrane materials. Thus, in the absorber, when the diluents and the heating media flow through the absorber simultaneously, the vapor and heat of the diluents penetrate through the membrane materials and are transferred to the heating media, and the heating media are diluted and heated. Compared with the prior art, the absorber can work at normal pressure; the diluents can be imported into the absorber without being evaporated; the structure of the system is greatly simplified; the evaporation and liquefaction process of the diluents are omitted, energy consumption of the system is substantially reduced, and energy efficiency is effectively improved.

Description

technical field [0001] The present application relates to the technical field of absorption heat pumps, in particular to an atmospheric pressure absorber and an absorption heat pump system. Background technique [0002] In daily life and industrial production, a large number of places need to obtain thermal fluid or raise the ambient temperature through certain methods. The common method is to obtain high-temperature heat energy by burning fossil fuels or directly use electric energy to drive refrigeration or heating units to obtain heat. Direct use of electricity consumes high-grade energy, while burning fossil fuels consumes precious non-renewable energy on the earth. At the same time, the smoke emitted from fossil fuel combustion will also cause a certain degree of damage to the environment. Therefore, many scholars are committed to the research and development of heating systems directly driven by renewable energy or low-temperature industrial waste heat, so as to reduce...
