Abstract:
A method for determining an operating condition of a condenser coil of a refrigeration system, comprising the steps of:a) checking to see if said system is in a steady operating state;b) determining a saturated condensing temperature of said system;c) determining a saturated suction temperature of said system;d) determining an ambient air temperature of said system;e) calculating a total heat rejected in a condenser of said system from values obtained in steps (b), (c), and (d);f) calculating a heat transfer coefficient from values obtained in steps (b), (d), and (e);g) comparing said calculated heat transfer coefficient to an ideal heat transfer coefficient to obtain a value representing said operating condition of said condenser coil; andh) outputting a message to a user of said system based on said value obtained in step (g).
