a ton of refrigeration effect is defined as the
What is a ton of refrigeration equivalent to _______________?
Before refrigeration air conditioning was invented, cooling was done by saving big blocks of ice.
When cooling machines were invented, their capacity was rated by the equivalent amount of ice melted in a day, which is where the term “ton” came from in sizing air conditioning systems.What does refrigeration effect mean?
Refrigerating Effect.
This is the heat absorbed in the evaporator per lb of refrigerant.
It is determined by the difference in enthalpy of a lb or refrigerant vapor leaving the evaporator and that of a lb of liquid just upstream (ahead) of the expansion valve at the evaporator.What is the ton of refrigeration effect?
A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment.
Generally, TR is defined as the amount of heat transferred to freeze or melt 1 short ton of ice at 0 deg.
C in 24 hours. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load.
