Low Recirculation Rate Evaporators

摘要

Fin coil evaporators with enhanced internal tube surfaces allow for optimum performance with a minimal overfeed rate. Reducing the overfeed rate requires less pumping power and smaller line sizes to the evaporator. Additionally, less compressor power is required for the same refrigeration capacity because the wet suction line pressure drop is reduced. Lower compressor power results in substantial electrical power savings over the life of the facility. With internal tube enhancement, top-fed evaporators can perform as well as bottom-fed evaporators while using a reduced refrigerant charge during full and part load operation.
