Absorption Type Air Conditioner
Compared to the vapor compression systems that uses mechanical energy to function, the absorption air conditioning is driven by heat energy. It uses a chemical process to change low temperature and low pressure vapor into high pressure vapor. The commonly used refrigerant in this system is water and ammonia or lithium bromide. The heat source that can be used are steam, natural gas, liquefied petroleum, kerosene, solar heated water, geothermal heated water or resistance heating that utilizes electricity.
