Preventive maintenance of refrigeration equipment

Preventive maintenance work performed on refrigeration equipment.

In this article we will try to explain to you the concept of Preventive maintenance, its difference from refrigeration equipment repair, what is performed on equipment during preventive maintenance, meaning, goals, and payback.

Work performed on equipment.

Visual inspection:

Check for visible damage (integrity of glass, double-glazed windows, glass fasteners, shelf holders, presence of shelf mounting screws, presence of dents, scratches, functionality of night blinds)

Check the correct loading of goods into commercial refrigeration equipment

Check the tightness of the melt water drainage system from commercial refrigeration equipment, clean the melt water drainage system

Monitor the cleaning and washing of commercial refrigeration equipment (location of the evaporator, shelves, walls, undercounter units);

Check the output of commercial refrigeration equipment to the required mode;

Checking the completeness of the equipment;

Checking the condition of covers, handles, guards, seals, drains, doors and rubber door seals

Checking the reliability of equipment fastening to the floor, wall, work stand;

Inspection of the refrigeration section:

Check the condition of the evaporator (presence of oil leaks, snow “coat”, uniformity of freezing);

Listen to see if there is any increased noise emitted by the unit;

Inspect the unit for visible damage or oil leaks;

Inspect and touch the compressor (the compressor suction should be cold, freezing may be observed, the temperature on the discharge line should be from 60’C to 90’C (the water should not boil); the compressor crankcase temperature should be 20’C higher than the ambient air temperature);

Inspect the piping on the discharge line and the condenser drain line for visible damage and corrosion, especially in the melt water evaporation bath;

Inspect the suction line for visible damage, frozen insulation, oil leaks;

Inspect the condenser for contamination of the condenser working surface and oil leaks, Clean and wash the condenser working surface from dirt and dust (clean with a brush or vacuum cleaner, wash with water or a special cleaning liquid)

Check for refrigerant leaks in the condensing unit, evaporator, capillary tube and piping lines, especially in the water evaporation bath;

Clean the compressor unit from dirt and dust;

Checking the operation of automatic and semi-automatic defrosting systems;

Inspection of the electrical part:

Check the serviceability of the lighting inside the commercial refrigeration equipment;

Check the serviceability of the lighting fittings of commercial refrigeration equipment (the presence and serviceability of lamp shades, the fastening of lamp holders, the integrity of electrical wires, the serviceability of electrical ballasts and starters);

Check the serviceability of the switches for lighting lamps and power supply of commercial refrigeration equipment;

Check the functionality and fastening of the temperature sensors of the electronic control unit of commercial refrigeration equipment;

Check the operability of the heating elements for the glass and superstructure pillars, measure the consumption currents,

Check the functionality of the defrost heating elements, measure the consumption currents,

Check the functionality of the electromechanical time relay,

Check the functionality of all condenser fans;

Check the direction of rotation of the condenser fans (the direction of air flow through the condenser towards the fan motors),

Measure the operating currents of the compressor electric motor;

Check and tighten all electrical contacts in the compressor terminal boxes;

Clean dust from electrical components of commercial refrigeration equipment;

Check and tighten all electrical contacts of commercial refrigeration equipment, check the condition of circuit breakers and block contacts, check the condition of connecting wires.

Inspection in terms of parameters:

Check the serviceability of the lighting inside the commercial refrigeration equipment;

Check the pressure in the suction line (the pressure should be within the range for a medium-temperature system from 2.5 to 3.5 Bar, for a low-temperature system from 0.2 to 0.7 Bar);

Check the readings of the electronic control units of commercial refrigeration equipment, check the settings of the electronic unit, and, if necessary, change the operating parameters of the unit to suit the required operating conditions.

Check the insulation resistance of the wires of an electric cable relative to the ground and to each other;

Refrigeration equipment – refrigerated and frozen tables, refrigerated chambers, freezing chambers, ice generators, freezers, shockers, shock freezing chambers, air conditioners, and other compressor equipment.

Goals:

Early detection of potential equipment faults

Parameter control, error diagnostics, comprehensive diagnostics.

Cleaning of equipment, cleaning of all systems.

During preventive maintenance, any identified defects are eliminated immediately, and if spare parts are needed, the order is sent on the day of the maintenance.
