H-6822 REFRIGERATION CYCLE DEMONSTRATOR 

The Hampden Model H-6822 Refrigeration Cycle Demonstrator provides the student with an introduction to the Second Law of Thermodynamics, which states that heat will not pass from a cold region to a hot region without an external agency. The student will be able to observe the evaporator where heat is taken in as the liquid evaporates at low pressure and the condenser where the high pressure vapor condenses and rejects heat. The compressor uses a work input to increase the pressure vapor and the expansion valve controls the flow of liquid from the condenser back to the evaporator.
