Abstract

The invention discloses a diffusion absorption type thermal converter. The diffusion absorption type thermal converter comprises a generator, a lifting pipe, a first gas-liquid separator, a rectifying device, a condenser, a second gas-liquid separator, an evaporator, an absorber, a liquid reservoir, a heat regenerator and a fan which are sequentially connected. In the invention, a thermally driven gas bubble pump is adopted to realize simultaneous pumping of an absorbent solution and a refrigerant liquid, and no mechanical solution pump or refrigerant pump is required, thus the structure of the thermal converter is greatly simplified, precious electric energy is saved, and the operation reliability is improved. The thermal converter disclosed by the invention is especially applicable to occasions in which low and medium temperature thermal resources are rich and high temperature thermal resource is required, thus the thermal converter has a good application prospect.

Description

technical field [0001] The invention belongs to the field of absorption heat pump and low-grade energy utilization, in particular to a diffusion absorption heat converter. Background technique [0002] The absorption heat exchanger can be driven by low-grade energy, and can effectively utilize low-grade energy such as industrial waste heat, geothermal heat, and solar energy. In addition, the absorption heat exchanger can avoid the use of refrigerants that can damage the atmospheric ozone layer, so it is very important for energy saving. and environmental protection are of great significance. Traditional H 2 The O / LiBr absorption heat exchanger has been put into commercial application, but due to the high operating temperature of the mechanical solution pump, H 2 The strong corrosiveness of O / LiBr solution limits its wide application. [0003] Diffusion-absorption refrigerator achieves the effect of cooling by diffusing refrigerant into the diffused gas. The inside of the ...
