Since one ton of refrigeration is equal to 12,000 Btu/h and one hp is equal to 2,545 Btu/h, the energy required to produce one ton of refrigeration, expressed in hp/ton, as shown in Equation 33-2, is 4.72/COP. In SI units, this would be expressed as:


If, in the previous example where the COP was found to be 10, the heat removal rate was 12,000 Btu/h, the work required, based on Equation 33-2, would be calculated as:
