WebFigure 2.4: Basic Refrigeration Cycle (Green, 2008) The capacity of a refrigeration unit is the rate at which heat is removed, expressed in tons of refrigeration. One ton of refrigeration is the refrigeration produced by melting one ton of ice at 32°F in 24 hours. It is the rate of removing heat equivalent to 12,000 British thermal units per WebWhen a refrigeration system producing low to normal refrigeration operates continuously without stopping and has high suction pressure and high head pressure , the probable cause is 1. an inefficient compressor 2. a low side restriction 3. noncondensables trapped in the condenser 4. an undercharge of refrigerant
