Evaporator and Condenser Calculations
Fin & tube heat exchangers are widely used in industrial and residental air conditioner systems. Residental air conditioners, VRF-VRV systems, roof top units, pool dehumidifiers and direct expansion type air handling units are the most common examples of the areas where this type of heat exchanger is used. Generally in air conditioning systems; Finned-tube heat exchangers are used on the indoor air conditioning side, finned-tube or micro channel heat exchangers are used as condensers. In this study, the mathematical model of finned tube evaporator and condenser calculations were investigated. In addition, the effect and performance information of the homogeneous and nonhomogeneous air distribution on fluid flows in the evaporator and condenser circuits are examined.
