Working principle
Liquid evaporation is a phase changing and heat absorption process. The lower pressure, the lower evaporation.
for example, under one atmosphere pressure, the evaporation temperature of water is 100°C, and at 0.00891 atmosphere pressure, the evaporation temperature of water will drop to 5°C. If a low-pressure environment can be established and water is used as the evaporation medium, low-temperature water with a saturation temperature corresponding to the current pressure can be obtained. If the liquid water can be continuously supplied, and the low pressure can be maintained stably, the low-temperature water of the required temperature can be continuously provided.
LiBr absorption chiller, depending on the characteristics of LiBr solution, takes the heat of steam, gas, hot water and other media as the driving source, and realizes the evaporation, absorption, condensation of refrigerant water and the generation process of solution in the vacuum equipment cycle, so that the low-temperature evaporation process of refrigerant water can continue. That means the function of continuously providing low temperature chilled water driven by the heat source can be realized.
