1 TR is equal to 12,000 BTU per hour.

• TR stands for 'ton of refrigeration', a unit used in air conditioning and refrigeration to measure cooling capacity.

• BTU stands for 'British Thermal Unit', a unit of energy used to measure heat.

• 1 TR is equivalent to 3.51685 kilowatts.

• To convert BTU to TR, divide the BTU by 12,000.

Vapour compression cycle is a thermodynamic process used in refrigeration and air conditioning systems.

• It involves the compression of a refrigerant gas to a high pressure and temperature, followed by condensation into a liquid at a lower temperature.

• The liquid refrigerant then passes through an expansion valve, where it undergoes a pressure drop and evaporates at a low temperature and pressure.

• The evaporated refrigerant absorbs heat from the surroundings, cooling the space or...read more
