How do you calculate evaporator size?

Answer 1

To calculate the size of an evaporator, you need to determine the desired cooling capacity, which is typically measured in BTUs or kilowatts. This involves assessing the heat load that needs to be removed from the system, considering factors such as temperature differences, fluid flow rates, and the properties of the refrigerant. Once the cooling capacity is established, you can use the appropriate formulas or manufacturer's specifications to select the evaporator surface area and design necessary to achieve that capacity efficiently. Additionally, factors like the type of evaporator (finned-tube, shell-and-tube, etc.) and operating conditions must be considered.
