ABOUT THERMAX ABSORPTION COOLING TECHNOLOGY Thermax offers a diverse range of Profetherm Solutions which help you get 'Profit from Heat'. These solutions are energy efficient and reduce operating cost. Thermax Profetherm Solutions include Lithium Bromide absorption chillers as a cost effective alternative to electricity-driven compression chillers. Our absorption chillers also known as VAMs (vapour absorption machines) are extensively used in a variety of industries as well as commercial buildings for process-cooling and air-conditioning. Thermax Profetherm range of absorption chillers cater to industrial-cooling, commercial air-conditioning as well as industrial and space heating needs. Our USP lies in identifying the unused heat available at the customer's plant and providing recovery based or live energy based solutions to optimize energy thus reduce operational cost. Read More BASICS OF ABSORPTION COOLING Vapour Absorption chillers uses water as the refrigerant and Lithium Bromide (LiBr) solution as the absorbent. The process of cooling goes through stages such as evaporation of refrigerant in evaporator, absorption of refrigerant by concentrated LiBr solution in absorber, boiling of diluted LiBr solution to generate refrigerant vapour in generator and condensation of refrigerant vapour in condenser. The boiling point of water is directly proportional to pressure. At 6 mm Hg absolute pressure the boiling point of water is 3.7C. To change water from liquid to vapour it has to be heated. The heat, required to change the phase of a liquid to vapour, is called the Latent heat of evaporation. Lithium Bromide (LiBr) is a chemical similar to common salt (NaCl). LiBr is soluble in water. The LiBr water solution has a property to absorb water due to its chemical affinity. As the concentration of LiBr solution increases, its affinity towards water vapour increases. Also, as the temperature of LiBr solution decreases, its affinity towards water vapour increases. Further, there is a large difference between vapour pressure of LiBr and water. This means that if we heat the LiBr water solution, the water will vaporise but the LiBr will stay in the solution and become concentrated.+ Read More
