Cooling water supply is mandatory for which specific components in an ammonia absorption refrigeration plant__________________?
Show answer Hide answer
Answer: E. condenser, absorber and separator (rectifier)
Explanation
An ammonia absorption refrigeration plant requires cooling water to remove heat from multiple system components. The condenser needs cooling water to liquefy high pressure ammonia vapor efficiently. The absorber and separator rectifier also require continuous cooling water flow for proper operation. Absorption systems use thermal energy instead of mechanical work to drive the refrigeration cycle. The absorber dissolves ammonia vapor into a weak solution, releasing heat that must be removed. Rectifiers purify ammonia vapor by condensing and removing unwanted water vapor before the condenser.
Large industrial absorption chillers require reliable cooling tower water supplies for continuous operation. Failure of the cooling water supply can cause excessive system pressures and emergency plant shutdowns. Facility engineers carefully monitor cooling water temperatures to maintain optimal absorption plant efficiency. Listing only the condenser ignores the critical heat rejection requirements of the absorber and rectifier. Listing only the absorber misses the essential cooling needed at the condenser and separator stages. Omitting the separator or absorber leaves out vital heat transfer surfaces requiring cooling water.
