Predication of Vapor Compression Refrigeration System Performance under Cyclic Loads

Abstract

An experimental investigation to a vapor compression system working under cyclic loads was conducted. The performance was predicted also by using RLS method. Two different cases were tested, isolated condenser pool and cooled condenser pool along with two heater loads 300W and 500W. The RLS prediction method proves satisfactory in anticipating system reaction. The 500W load case resulted in an unstable cyclic evaporator behavior for both cooled and uncooled cases in contrast to 300W load that shows cyclic but stable response. The effect of condenser cooling has kept the condenser temperature almost constant for both load cases.Keywords: Refrigeration, isolated condenser pool, RLS, cyclic load, heat pump, performance
