چیلرهای جذبی و تراکمی چگونه کار می کنند
Absorption chiller
Following is a description of the cooling cycle in a direct-fired, two-stage, absorption liquid chiller, powered by natural gas. Absorption cooling relies on three principles: 1) Liquids, such as water, boil (evaporate) at a lower temperature when under low pressure; 2) Lithium bromide has a strong affinity for water and readily absorbs it, and; 3) in a sealed (hermetic) system a vacuum is created when water in the system is absorbed by lithium bromide. While the description of the process is broken down into stages to make the process easier to understand, in actuality the process is continuous.
Gas Engine Chiller
A gas engine chiller, as shown in the schematic above, mates a natural gas internal combustion engine to a compressor-driven chiller.
