A small air-cooled absorption refrigerator

Abstract

The invention discloses a small air-cooled absorption type refrigerating machine which comprises a generator, an air-cooled condenser, a throttle valve, an evaporator, an absorber, a solution pump, an air-cooled precooler, mixer, a throttle valve, a solution heat exchanger and a diverter or an absorber circulating solution pump. A heat exchanger is arranged in the generator. A spraying device, fillers and heat transmitting pipes are arranged in the absorber. By the adoption of the non-adiabatic absorber and the path combination of the non-adiabatic absorber, the small air-cooled absorption type refrigerating machine solves the problem that the circulation amount of solutions in the absorber needs to be greatly increased in order to prevent the temperature of the absorbed solutions from being too high in the air-cooled heat insulation absorption refrigerating circulation on the basis of achieving the air-cooled absorption type refrigerating circulation, reduces the flow and wasted power of the solution pump, reduces the heat load of a solution cooler, improves the absorption effect of the absorber, increases refrigerating capacity and improves the circulating efficiency.

Description

technical field [0001] The invention relates to an absorption refrigerator, in particular to a small air-cooled absorption refrigerator. Background technique [0002] In recent years, with the development of the world economy, human beings are facing the increasingly serious threat of global warming and energy depletion. Energy conservation, emission reduction and the development and utilization of renewable energy have become the most important research topics in the field of energy utilization. At present, there are two types of air-conditioning and refrigeration devices: electric drive compression type and thermal energy drive absorption type. The electric-driven compression type is becoming one of the necessities of life and industrial production. Its widespread use not only causes the imbalance of power supply ratios such as the peak-to-valley difference in urban power consumption, that is, the peak power supply exceeds demand, and the low-valley power supply exceeds de...

AI Technical Summary

Problems solved by technology

Air-cooled adiabatic absorption refrigeration Since the absorber adopts adiabatic mode, the heat generated in the absorption process must be absorbed by the solution itself. Greatly increase the circulation of the solution in the absorber, which not only greatly increases the flow and power consumption of the solution pump, but also increases the heat load of the solution cooler
