To ensure that your refrigeration equipment operates reliably and lasts for a long time, we recommend following a few simple tips when using it:

Any refrigeration machine must cool appropriately. For this purpose, special slotted openings (grids) are provided in the housing of the refrigeration equipment, which must not be blocked under any circumstances - otherwise air access to the refrigeration unit is stopped and overheating occurs. refrigeration machine, which can lead to its failure.

Maintaining the proper temperature conditions is of great importance for maintaining the functionality of your equipment: operating the refrigeration machine in a room with elevated temperature air may trigger protective devices motor-compressor, or to premature failure of the motor-compressor. Try to locate the refrigeration machine in areas with good ventilation, or provide forced cooling of the room in which the refrigeration machine is operated.

At the same time, operating the refrigeration machine in a room with low temperature air can lead to a decrease in pressure in the refrigeration system to an unacceptable level and, as a consequence, to premature failure of the motor-compressor.

The presence in the air of the room where the refrigeration machine is operated, oil vapors provokes rapid pollution refrigeration unit. Preventative work on cleaning the condensers of refrigeration machines operating in such conditions should be carried out at least twice as often.

Here are the basic rules adopted when operating refrigeration and freezer compartments:

1. It is necessary to lay the goods correctly: the products should not block the air cooler;

2. It is preferable to store hermetically sealed products (especially fish) in the refrigerator. Poorly packaged products release an excessive amount of moisture, and a snow “coat” very quickly forms on the air cooler of the refrigeration chamber;

3. It is necessary to regularly defrost the refrigerating chamber and disinfect it in accordance with the operating instructions;

4. Do not overload refrigerator products, fill it to capacity, filling the entire volume. Do not allow food to come into contact with the panels of the refrigerator compartment. There must be a distance between the rows of stacked products to ensure free circulation of air inside the refrigerator compartment;

5. It is necessary to operate the refrigerator compartment only in accordance with temperature conditions storage of a specific group of goods, it is impossible to store fresh meat with a temperature of +2? C in a refrigerating chamber with a temperature of -18? C and use the refrigerating chamber for freezing products. If it is necessary to freeze or cool products in storage rooms, you must notify the company that sells the refrigeration equipment in order to avoid future problems with the implementation of the warranty (does not apply to equipment used for other purposes).

trust the installation, start-up and operation of the unit to random persons;

start and operate a unit with faulty or incomplete electrical equipment, without a fan unit, without grounding or with unreliable grounding, with open live parts;

turn on, even for a short time, the unit with the discharge valve closed, if there is one. To avoid compressor damage, the discharge valve should be fully open before turning on the unit;

operate a unit with a refrigerant leak (permissible leakage 0.5 g/year), such a unit must be turned off immediately. Smoking and working with open fire are not allowed near the unit with a freon leak;

IN full cycle operation refrigeration technology includes measures for delivery to the installation site, installation and commissioning, service and refrigeration equipment maintenance, warranty repairs and post-warranty service. To ensure trouble-free and long-term service of products, all of the above work has a certain significance.

But it’s worth focusing separately on maintenance, which in certain situations becomes vital. Regular maintenance, during which preventive actions, allows you to promptly identify problems and breakdowns of machines, troubleshoot problems in a timely manner and support high level productivity refrigeration systems. These actions will prevent complete failure of refrigeration equipment, thereby saving cash enterprises for expensive repairs and costs associated with damage to goods.

general information

Maintenance of refrigeration equipment is carried out at certain intervals and is scheduled, preventive and periodic in nature. The duration and volume of work included in the list depends on the purpose and type of units, technical condition, modes of use and operating time. Equipment cooling systems are checked based on the requirements of operational documents for each separate species devices and equipment.

The main purpose of maintenance of refrigeration equipment is periodic inspection, repair and prompt elimination of failures and malfunctions of the refrigeration system and electrical equipment of machines.

Considering that refrigeration equipment is a complex electrical structure that is used in quite a lot of difficult conditions, you should trust equipment service only to highly qualified specialists who will not only carry out high-quality necessary measures, but will also give competent advice on operation and avoidance of possible breakdowns.

Types of maintenance

Maintenance of refrigeration equipment can be one-time (or when putting machines into operation), seasonal and planned. One-time, including a certain list of operations (assessment of technical condition, cleaning and flushing of capacitors, identifying possible malfunctions) is carried out before or after starting refrigeration machines, as well as after a certain operating time or based on the technical condition of the products.

Seasonal maintenance of refrigeration equipment is only necessary for those machines that are used under significant changes weather conditions during a year. The planned one is carried out with a certain regularity, in accordance with the requirements established by the manufacturers.

Scheduled maintenance is optimal solution, since with this approach, identification and elimination of certain faults occurs in advance. It is carried out at least once a month, if necessary 2-3 times monthly. The cost of servicing refrigeration equipment is calculated individually depending on the power of the machines, their technical condition, conditions of use and the number of installed products. The conclusion of a maintenance agreement occurs after the purchase of equipment.

List of works carried out

The list of work carried out during the period of maintenance of refrigeration equipment includes:

• external inspection of equipment to identify mechanical damage housing, internal volume and checking compliance of operation with safety regulations;
• checking the completeness, presence of a protective fence of the component compartment, reliability of fastenings and grounding;
• inspection and testing of automation devices, electrical equipment, lighting fixtures, fittings and tightening of connections;
• checking the tightness of the installation, defrost system, compressor, electric motor, operability of refrigeration equipment and its components.

In addition, the oil level in the compressor crankcase and refrigerant, condensation pressure, solenoid and water control valves must be monitored. Checked temperature regime in a refrigerated volume and automatic operating mode. A note is made in the accounting journal about the activities carried out.

In cases of identified malfunctions or, if necessary, during maintenance of refrigeration equipment, additional measures are taken:

• adjustment of TRV and RD valves, VRV, SVM, thermostat, thermal protection, gap between diffuser and fan, tightness of fit and movement of doors and curtains of refrigeration machines;
• replacement of thermal elements;
• elimination of oil and refrigerant leaks, as well as malfunctions causing increased level noise of operating refrigeration equipment;
• refilling refrigeration machine systems with oil and refrigerant, installing process filters;
• tightening of fan belts, fasteners and drives;
• trouble-shooting protective fences, brackets, shelves, etc.;
• conducting additional training for employees of enterprises on correct operation refrigeration equipment.

Timely and competent maintenance of refrigeration equipment is the basis for its uninterrupted and long-term operation.

At the end of the courses a qualifying exam is held. After successful completion exam, a CERTIFICATE of the established form is issued.

Training taking into account the requirements of professional standards

The term “refrigeration equipment” includes a huge amount of equipment. This household refrigerators And industrial systems refrigeration, sales counters and huge warehouses, many special machines and much more.
