Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an adiabatic absorption refrigeration cycle device. Background technique [0002] Absorption chillers are driven by thermal energy, which can be high-grade thermal energy, such as high-temperature and high-pressure steam or hot water, fuel oil or gas, or low-grade thermal energy, such as waste heat, waste heat, solar energy or geothermal heat, etc. Absorption refrigerating machines can realize the effective utilization of renewable energy such as solar energy and geothermal energy, and use water, ammonia or HFCs as refrigerants, which are energy-saving and environmentally friendly, and are one of the better refrigeration methods to replace electric compression refrigeration. Due to the advantages of fewer moving parts, reliable operation, less power consumption, energy saving and environmental protection, absorption refrigerators are widely used in industrial, commercial an...

Problems solved by technology

[0004] The Chinese patent specification with application number 200410025649.5 discloses a small-scale energy-saving air-cooled adiabatic absorption gas-fired air conditioner, which includes an adiabatic absorber equipped with a solution cooler. The absorption heat removal process is carried out in the solution cooler, so that the absorption mass transfer and absorption heat transfer process are carried out separately, so that the mass transfer space and time are greatly increased in the adiabatic absorption process in the absorber, so that the mass transfer process can be effectively strengthened. The intensification of the heat transfer process in the solution cooler is also easy to achieve, thereby effectively reducing the volume of the absorber and realizing the miniaturization of the unit, but it is necessary to add a solution pump device, which will cause an increase in initial investment and power consumption. The absorption effect of the device is also limited by the evaporation pressure and other issues.
