Maintenance of cooling and freezing equipment

The following maintenance checklist can help companies prolong the useful life of their refrigeration equipment. Condensers Clean them regularly, especially air-cooled types The frequency of cleaning depends on the condenser location and its surrounding environment Check fan/pump motors all work Check fans are not loose on motors Compressors Carry out standard maintenance if required Recover oil and recharge compressors as necessary (ammonia systems) Air coolers Clean them regularly Check the defrost (where necessary) is working correctly Check the defrost control allows the optimum time for defrosting Check fan/pump motors all work Check fans are not loose on motors Liquid chillers - Check water pump operation. Liquid line filter drier - Check for blockage and replace if necessary. Refrigerant charge Check liquid level in the receiver or check for bubbling in the liquid line sight glass Check for leaks all-round the system and repair (this is required under EU 'F-gas' regulations on the use of fluorinated greenhouse gases) Control Ensure the discharge pressure is as low as possible; in particular, check that head pressure control settings are not too high Check that the suction pressure is as high as possible Check cold room/process temperature set points; they should not be lower than required Check superheat setting of expansion valves and adjust if necessary Insulation Replace suction line insulation if necessary Replace chilled liquid line insulation if necessary Repair or replace cold store insulation if necessary Cold store doors Ensure doors are not left open unnecessarily Repair or replace door seals if necessary Repair or replace strip curtains if necessary Repair or replace air curtain if necessary Ice build-up If condensate pipes are iced-up, applying gentle heat will help to defrost Integral defrosting elements should work correctly Ice build-up on evaporators indicates to poor heat exchange Light ice build-up can be removed with a brush, but heavy ice has to be removed as described in manufacturer guidelines In order to avoid damage, sharp objects should never be used for de-icing The Retail Code of Conduct includes information on service and maintenance of cooling systems
