3 Operation Cycle Physical & Performance Data Cooling cycle Water is used as the refrigerant in evaporator maintained under low highly vacuum state. In the cooling mode, the chiller operates on the principle that under vacuum, water boils at a low temperature, thereby cooling chilled water. To make the cooling process continuous, refrigerant vapor must be removed as it is produced. A lithium bromide solution (which has a high affinity for water) is used to absorb refrigerant vapor. As this process continues, lithium bromide becomes diluted, reducing its absorption capacity. A solution pump then transfers this weak solution to the high temperature generator where it is heated and re-concentrated to a medium concentration solution by the heat from the combustion of fuel. The medium concentration solution flows to the low temperature generator where it is heated and re-concentrated to a strong solution by the high temperature water vapor released from the solution in high temperature generator. The water vapor released in the shell-side of low temperature generator, in addition to the condensed water vapor from the tube- side of low temperature generator, enters the condenser to be cooled and returned to a liquid state. The refrigerant water then returns to the evaporator to begin a new cycle. To remove heat from the machine, cooling water is first circulated through the tubes of the absorber to remove the heat of the evaporator. Then it is circulated through the tubes of condenser. The strong solution from the low-temperature generator flows back to the absorber to begin a new cycle.

This condensed water then flows to the absorber where it mixes with the concentrated solution returning from the high temperature generator. The diluted solution is then pumped back to the hightemperature generator to repeat the vapor generation phase for the heating function. Electric Dimensi on Ref.
