Single-Hmm Effect
Fig. 2.20 shows one Cooling Effect. Evaporator contains a set of pipes that carry the water in the cooling system/chilled. This part hmm, where the cooling system's water occur. Cooling cycle begins when a high-pressure liquid refrigerant from the condenser, passes through a hole in the bottom-pressure in the evaporator, and collects in the evaporator pan or Carter. This step of the cycle causes the "flashes" of some of the refrigerant entering the evaporator and cools the remaining liquid refrigerant, which is sprayed over the pipes carrying the water in the system. The transfer of heat from a relatively warm-water system is cooled by the refrigerant, is the last evaporates and cools the water in the installation of pipes.
The refrigerant vapour generated in the evaporator, migrate to low pressure, absorber, where couples are absorbed by lithium bromide absorbent solution sterilized during the absorber tube bundle. Sink and an evaporator share of the vapor space, allowing the generated pair of refrigerant into the evaporator to migrate permanently to the absorber.
Absorption process creates a pressure below, figure continuous supply of refrigerant vapour at the outlet of the evaporator to the absorber.
In addition, the absorption process of condensation of the refrigerant vapor and releases the heat coming from the evaporator, the refrigerant. The heat generated from the condensation of refrigerant vapors and their absorption in the solution is removed from the absorber by transfer to a cooling coil, established in absorber, through which the cooling tower water circulates. Cooling tower water releases heat from the absorber for a tower, installed at the facility.
Diluted lithium bromide solution absorber in the form of continuously pumped from the absorber to the generator, which operates at a higher pressure. In the heat generator (from natural gas, steam or hot water is added to boiling of refrigerant vapour is absorbed in the absorber. Concentrated lithium bromide solution produced by the generator returns a shock absorber.
The refrigerant vapors created in the generator migrate to cooler condenser. Cooling tower water circulating through the capacitor makes refrigerant vapors to a liquid state and takes the heat of condensation that he refuses the tower. The liquid refrigerant is returned to the evaporator, and terminates the loop.
The heat exchanger is designed to restore some of the heat from the concentrated lithium bromide solution goes from the generator heat sink dilute lithium bromide solution is gathered from the absorber of generator...
