VAPOR ABSORPTION REFRIGERATION QUESTIONS ANSWERS Vapor absorption system can operate without the use of electricity. The heat energy operates the system. Obtain heat by burning of fuel or wood & solar energy. Use of solar energy makes it eco-friendly. It resembles very much with a vapor compression system. It uses different means of compression….
VAPOR COMPRESSION REFRIGERATION MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ increases clarity and understanding. Most commonly used method of refrigeration is vapor compression refrigeration. Cooling capacity is the cooling produced per minute. Refrigeration is measured in tons of refrigeration (1 ton = 211kJ/min of cooling effect).Cooling effect is caused by latent heat in vapor refrigeration…

VAPOR COMPRESSION REFRIGERATION QUESTION ANSWERS Question answers on basics of refrigeration increases the level of understanding very deeply. Compressor, condenser, receiver, evaporator are essential components of refrigeration. Condensing unit is motor, compressor, condenser and receiver. Different prime movers run refrigeration units. What is the meaning of condensing unit? Condensing unit is the assembly of motor,…
. VAPOR ABSORPTION REFRIGERATION CLASS NOTES As cooling requirements increase, volume of refrigerant increase. It increases the size of the compressor and the power requirements. Volume reduction decreases Power requirements. Here comes the role of absorption. Water has extremely high affinity for ammonia and Lithium Bromide has high affinity for water. Water in the absorber…
