illustration of Coefficient of Performance (COP)
Anyone who installs an HVAC system as a smart energy-saving solution at home must know what coefficient of performance (COP) is. This is a parameter for calculating the efficiency of heating, ventilation, and air conditioning performance in HVAC systems. The amount of operating costs has a deep impact on this COP.
When the COP value is higher, it means the efficiency is higher and energy consumption is lower. This can lower operating costs. When you decide to install an HVAC system in a property, whether it’s a house or office, you have to be observant in knowing the coefficient of performance. Simply put, COP is a performance rating that shows how effective your heat pump or cooling system is at transferring heat and it relates to daily electrical power consumption.
Meanwhile, heat pumps and air conditioners work contrary to the law of thermodynamics. We know that heat will naturally flow from a hot area to a cold area. A heat pump will pump heat to high-temperature areas there will be performance attempting this hot upward movement. That’s when the COP comes to state how effectively the heat pump or air conditioner does its job.
There will be an indicator that tells you how much power is output for the machine to work optimally. Coefficient of performance is important considering you may be curious about how much heat a heat pump can transfer with a certain amount of power and at a certain temperature.
The absolute temperature and relative temperature existing between the system and the sink affect COP. There will be a graph recording everything and the average of the conditions your HVAC system requires.

Coefficient of Performance Value to See the Efficiency of the Engine
Heat pumps are efficient. In fact, many people who have used them are starting to compare them to hot stoves. Unlike furnaces, heat pumps do not convert heat into energy. Instead, they take heat from the outside environment and pump it into the house.
Moreover, heat pumps will not convert much heat but rather transfer heat energy. The coefficient of Performance on the heat pump will give us clarity regarding the machine’s ability to transfer energy. Once we know what the COP value is, we will be able to achieve more output than input. We will then be able to see the condition of the heat pump capable of transferring heat energy considering that this type of pump will usually transfer more energy than the energy input.
Coefficiency of Performance will make us no longer create heat energy from electrical energy. We will only use a heat pump to transfer the available heat energy to the surroundings. This performance will be visible through the COP work. Heat pump COP is always bigger than 1 based on the performance ratio.
How to Calculate Coefficient of Performance
Cooling and heating modes will have different coefficient of performance values. For each heat pump in an HVAC system, there will be 2 COP values. These are instantaneous values that inform performance at specific indoor and outdoor temperatures. Therefore, we need to be careful in looking at the COP calculations and to what extent the COP value affects performance.
When you read about COP values you won’t find labels on residential or office HVAC equipment. There will be no data plate listing the COP value on your HVAC system. You will only find the COP value on the product specification data sheet. You can get it from the HVAC system manufacturer where you order it. If this is a large scale such as procuring an HVAC system for offices, then you can look for this information from your contractor.
However, if you are still curious about how to calculate the coefficient of performance, then you can follow the simple method. Calculation COP (without units) for heat pumps requires heat output from the condenser with the symbol Q and power supply to the compressor with the symbol W. Later you will see the relationship between the output of the heat pump as coolant or heat in the form of power and the power supply for the compressor.
When you look at certain heat pump data for air cooling with a COP value of 2, then 2 kW of cooling power must be present for every kW of power that drives the pump compressor. So, when you order the products from a heat pump manufacturer, you will get detail information about this COP.
