Non-flooding remote air cooled condensers

摘要

An outdoor air cooled condenser for a refrigeration installation having at least one refrigeration system circuit and including a condenser coil with a heat transfer surface, a condenser housing having air inlet and outlet means for the passage of air across said heat transfer surface, the outlet means including a primary outlet with air flow control means therefor and a plurality of secondary outlets with air displacement means and damper means associated therewith, sensing means for sensing a predetermined condition of refrigerant in the condenser coil, control circuit means for monitoring and integrating the sensed refrigerant condition with respect to a predetermined ideal condition set point value for the refrigeration system circuit and for operating the air flow control means and air displacement means for controlling the amount of air passing through the housing and across the heat transfer surface.
