Vapour Absorption Refrigeration System topics include: ideal VAR system and its performance, domestic electrolux and lithium bromide refrigeration system. A vapor absorption refrigeration system (VARS) is a refrigeration method that uses heat energy to change the condition of refrigerant vapors. Basically, a VARS is a heat pump with three thermal reservoirs. It uses the principle that liquids evaporate at low temperatures when the pressure is reduced. A basic VARS setup includes the following components: Absorber, Pump, Generator, Pressure relief valve, Condenser, Expansion device,...

A vapor absorption refrigeration system (VARS) is a refrigeration method that uses heat energy to change the condition of refrigerant vapors. Basically, a VARS is a heat pump with three thermal reservoirs. It uses the principle that liquids evaporate at low temperatures when the pressure is reduced. A basic VARS setup includes the following components: Absorber, Pump, Generator, Pressure relief valve, Condenser, Expansion device, Evaporator. Here's how a VARS works: Refrigerant vapors evaporate The vapors enter the absorber and get absorbed by an absorbent The pump pressurizes the rich refrigerant-absorbent solution from the absorber pressure to the generator pressure In the generator, the solution is heated by available low-grade heat As a result of heating, ammonia gas gets expelled from the strong solution in the generator and passes onto the condenser In the condenser, the ammonia gas is again condensed to liquid and passed on to receiver An analyzer separates water particles from ammonia vapor and only lets ammonia to pass through to the next components The residue weak solution of water and ammonia accumulated in the generator is passed back to the absorber Related Tests: Refrigeration and Air Conditioning Practice Test: Simple Vapour Compression Refrigeration Systems Refrigeration and Air Conditioning Practice Test: Compound Vapour Compression Refrigeration Systems Show less
