What is the power coefficient?
The
power coefficient concerns a change in the heat release ratio released at the output compared to the work that must be made to release this heat. This measurement is usually used to measure the output of heat pumps, but can also be used for other measurements. Power coefficient is sometimes short or CP. Different equations are used to determine COP in different applications. This rule states that energy can be changed, but it cannot be destroyed or it cannot be created. As a result of this rule, the equation used to determine the power coefficient generally begins to consider heat, which is taken from the air tank for cold heat and heat, which is released from the hot air tank.
For the determination of the power coefficient, the absolute temperatures of the heating and cooling tanks must also be considered in some equations. This changes the equation so that the absolute temperature of the hot air tank and the absolute temperature of the cold air tank is considered. When taking into account these absolute temperatures and using the Kelvin scale BUDE Calculated response to determine the maximum theoretical efficiency of units according to the first rule of thermodynamics. This equation is commonly used to determine the power coefficient for refrigerators and air conditioning.
The COP determination process is important because the comparison of the power coefficients can be used to determine the amount of energy that could be stored using one type of Versus system. For example, if an electric heat pump runs on a COP 4.5, it means that it provides 4.5 heat units and one unit of energy consumed for the EACH unit. If the user knows the price for kilowatt energy, then it can make informed decisions in terms of system type that can be more financially suitable for its needs or which of two systems is better purchase. For example, if the electric heat pump becomes more due to the price of electricity compared to the natural gas price, then it would be in the best financial interest to choose a system that runs on natural gas instead.
