How is the coefficient of performance different from efficiency?

Unlike for efficiency, the COP is defined as a ratio of Heat Input (absorbed) to mechanical work input (or commonly defined as cooling capacity divided by power absorbed).

What is EER in HVAC?

The Energy Efficiency Ratio (EER) of an HVAC cooling device is the ratio of output cooling energy (in BTU) to input electrical energy (in watts) at a given operating point. EER is normally calculated with a 95 °F outside temperature and an inside (return air) temperature of 80 °F and 50% relative humidity. What is EER in refrigeration? A room air conditioner's efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units (Btu) per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.

How do you convert EER to police?

To convert EER to COP, please use the following formula:

1. COP = (EER)/(3.41214)
2. COP = (SEER*1055) / 3600.
3. IPLV = 0.01A+0.42B+0.45C+0.12D.

How do you calculate the coefficient of performance for a refrigerator? The coefficient of performance of the fridge is the refrigerating effect per cycle, Q₁, divided by the net work done on the fridge per cycle, and, for a Carnot cycle it can be calculated from T₁/(T₂ − T₁).
