Refrigeration Cycle COP calculator:
This Refrigeration Cycle COP Calculator can be used to find the coefficient of performance of a hypothetical refrigeration system. Input evaporator and condenser temperatures to calculate COP, cooling effect, work input and heat rejection using step-by-step calculations.
Refrigeration Cycle COP Tool Formula:
\[ COP = \frac{Q_{C}}{W} \]
\[ COP = \frac{T_{C}}{T_{h} - T_{c}} \]
(where Qc = heat removed, W = work input, Tc = cold temperature, Th = hot temperature)
Refrigeration Cycle Cop Calculator is used to calculate the coefficient of performance (COP) of a hypothetical refrigeration and air conditioning cycle using engineers, students, and HVAC technicians. A cooling system in relation to its work input is a measure of its efficiency and is termed the COP
Users are allowed to enter evaporator temperature (T E ), condenser temperature (T C ), and work input (W) may be entered. The calculator uses common vapor-compression or Carnot refrigeration formulas to compute COP, refrigeration effect (Q L ), work input (W ), and heat rejected (Q H ) values:
Solutions step-by-step are used to demonstrate the flow of energy through each component; hence, it is simple to determine the efficiency of refrigerators, air conditioners, and heat pumps. SI units are supported: -C, K, kilojoulew, kilo watt. It is the best tool to use with mechanical engineers, HVAC engineers, students, and researchers to obtain an accurate analysis of energy consumption and performance of refrigeration systems.

Frequently Asked Questions - Refrigeration Cycle COP Calculator:
What is COP in refrigeration?
Coefficient of Performance (COP) is the ratio of refrigeration effect to work input in a cooling system.
How do I calculate COP of a refrigeration cycle?
COP = Q_L / W, where Q_L is the refrigeration effect and W is the work input. For ideal Carnot cycle, COP = T_E / (T_C - T_E).
What is evaporator temperature?
The evaporator temperature (T_E) is the temperature at which the refrigerant absorbs heat from the space to be cooled.
What is condenser temperature?
The condenser temperature (T_C) is the temperature at which the refrigerant rejects heat to the surroundings.
Can I calculate work input?
Yes, W = Q_L / COP.
Can I calculate heat rejected?
Yes, Q_H = Q_L + W.
Which units are supported?
Temperature in °C or K, energy in kJ or kW.
Who should use this calculator?
