Diffusion absorption type refrigeration system

Abstract

The invention relates to a dispersing absorption type cooling system, comprising a high evaporation temperature cooling loop, a low evaporation temperature cooling loop and a heat retriever that can respectively independently run; the high evaporation temperature cooling loop comprises a first generator, a gas-liquid separator, a condenser and a first evaporator and a first absorber; the first generator is driven by external heat source and connected with the condenser through the gas-liquid separator; the heat retriever is in series connection between the gas-liquid separator and the condenser. The dispersing absorption type cooling system of the invention, because including two respectively independently cooling loops with different evaporation temperatures, can efficiently use the remaining heat, the waste heat, the solar energy, the gas and the power energy as energy to cool and generate sanitary hot water, thus effectively performing energy replacement and improving comprehensive utilization of the energy, which is beneficial to solve the problem about shortage of power and environment protection radically in our country and to improve the energy consumption efficiency at the same time of protecting the natural environment of earth.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a diffusion-absorption refrigeration system, in particular to a diffusion-absorption refrigeration system with hot water recovery function and dual evaporation temperatures. Background technique [0002] Although the existing diffusion-absorption refrigeration system has a variety of products, it is generally driven by a thermosiphon pump, and the cooling capacity is small; and the operating temperature zones are arranged in series according to the evaporator process and need to be used at the same time. At present, its products mainly include small refrigerators driven by electric heating, gas or oil. It uses ammonia-water-hydrogen as the working medium, and uses air to cool the condenser and absorber, so its cooling capacity is not large, and it is mainly used for food freezing and refrigeration in hotels and homes. There are also a small number of products that have dua...

Problems solved by technology

Under the premise of other conditions being the same, the lower the evaporation temperature, the lower the comprehensive performance of the system

At the same time, since the difference between the boiling points of ammonia and water in the diffusion-absorption refrigeration system using ammonia-water-hydrogen as the working fluid is not very large, only about 133°C, a rectification device for purifying ammonia vapor must be installed in the refrigeration system, resulting in Loss and waste of part of the heat, so its overall efficiency is low
