So that your refrigeration equipment worked reliably and served for a long time, we recommend that you follow several simple tips if operating it:

Any refrigerator should coolant according to one. For this in the housing refrigeration equipment Special slotting holes (grids) are envisaged, to block which in no case cannot be - otherwise the air access to the refrigerator unit is stopped, the refrigeration machine overheating, which can lead to its failure.

Of great importance for maintaining the performance of your equipment has adherence to the proper temperature regime: Operation of the refrigeration machine indoors with increased temperature The air can lead to the triggering of the protective devices of the motor-compressor, or to the premature failure of the motor-compressor. Try to locate the refrigerator in places with good ventilation, or provide forced cooling of the room in which the refrigeration machine is operated.

At the same time, the operation of the refrigeration machine indoors with reduced temperature The air can lead to a decrease in pressure in the refrigeration system to unacceptable and, as a result, the premature failure of the motor-compressor.

The presence in the air of the room where the refrigeration machine is operated, oil vapors Provokes the rapid contamination of the refrigeration unit. Preventive work on capacitor cleaning refrigeratorsworking in such conditions should be carried out at least twice as often.

We present the basic rules taken during the operation of refrigeration and freezer:

1. It is necessary to put the goods correctly: products should not be blown up the air cooler;

2. It is preferable to store hermetically packaged products in the refrigeration chamber (especially fish). Poorly packaged products highlight an excessive amount of moisture, and snow "fur coats" is very quickly formed to the air cooler of the refrigerator;

3. It is necessary regularly, in accordance with the instruction manual, to detect the refrigerator and its disinfection;

4. You can not overload refrigerated Camera Products, score it "under the string", filling the entire volume. Do not allow the contacts from the refrigeration chamber panels. Between the rows of laid products, there must be a distance that provides free circulation of air inside the refrigeration chamber;

5. It is necessary to exploit the refrigeration chamber only in accordance with temperature conditions Storage of a specific group of goods, it is impossible in a refrigerator with a temperature regime -18? With steam meat with a temperature of +2? C and use a refrigeration chamber for product salary. If you need to freeze or cool the products in storage chambers, you need to inform the firm selling refrigeration equipment to avoid further problems with the implementation of the guarantee (it does not work on equipment that is not applicable to the appointment).

trust installation, startup and operation of the aggregate by random persons;

run and operate the unit with faulty or noncompliament electrical equipment, without a fan node, without grounding or with unreliable grounding, with open current-time parts;

include, even for a short time, the unit with a burdened injection valve, if any. In order to avoid breakage of the compressor, the discharge valve should be fully open until the unit is turned on;

operate the aggregate with the flow of the chladone (permissible leak of 0.5 g / year), such an unit must be turned off immediately. Near the aggregate with the county of the chladone is not allowed smoking and working with open fire;

The purpose of the technical operation of the refrigeration unit is to establish and maintain the specified temperature and humidity modes in cooled rooms. The main task is to ensure reliable, trouble-free and safe operation of the whole refrigeration equipment at minimum costs on the production of artificial cold.

The correct organization of the technical operation of the refrigeration unit must meet the requirements:

reliability and durability of the operated refrigeration equipment;

security and trouble-free operation.

Cost production costs associated with energy savings, labor, water, operational materials should be minimal.

Important condition The normal operation of the refrigeration is the presence of specially trained personnel. The personnel serving a refrigeration unit must be guided technical documentation on refrigeration, manufacturing instructions For maintenance of the entire installation as a whole, as well as individual units and elements.

With economical safe operation refrigeration installation must be observed optimal mode Its works, equip the installation of control and measuring devices, automatic control and protection devices, correctly fill the system with a refrigerant, contain the surface of the heat transfer of capacitors and evaporators in the purity of the heat transfer of the condenser and evaporates, to carry out the planned-preventive repair of refrigeration equipment, to maintain the daily refrigeration journal and compile technical reporting.

In commerce and catering enterprises, refrigeration equipment serve mechanics of specialized refrigeration equipment. Maintenance includes inspections carried out once a month with the implementation of preventive work and the necessary small repair, troubleshooting that may occur, daily inspection of the refrigeration function.

The amount of maintenance depends on the type of machines, installation schemes and the degree of automation.

Conclusion

Today, the manufacture of refrigeration installation techniques are on very high level. The development of new models of refrigeration units today raised even the sphere of microelectronics. Also did not bypass the technology and technology of production of refrigeration machines and digital computer technologies.

Application of refrigeration systems with computer control In everyday life adds convenience in their operation, creates energy savings, and computer control over the state of assembly assembly supports it more reliable and safe work For long years.

The use of refrigeration plants with computer control in production - increases production efficiency, ensures reliable temperature control. Thereby preserving the raw material and provides minimal losses.

Perhaps the main disadvantage of such installations is the complexity and high cost of repairing electronic parts of computer control. All other electronic components require special operating conditions. Another disadvantage is that computer control refrigerators are quite expensive, but the savings on minimal loss of raw materials during storage in production fully justifies the cost of the aggregates.

Another not an unavailable problem is the lack of specialists in the maintenance of such equipment. But most enterprises in Russia invite specialists from abroad to serve imported refrigeration facilities. Most of the digital control refrigerators comes from abroad.

Unfortunately in Russia, such refrigerators produce little, or produce, but under license foreign firms, respectively, such aggregates enter the market under the brand overseas company.

Therefore, it is necessary to develop in Russia the development and production of refrigerators and refrigeration units with digital control and create new technologies for their manufacture, so that Russian refrigeration units have become competitive in the global market.

The entry into the duty of replacement personnel begins with checking records in the journal of the refrigeration station, and ends with temperature control at the main points refrigeration cycle and checking the equipment of the refrigeration station.

Both shifts - passing and receiving - sign about the delivery and reception of the change in the journal.

The duty officers periodically check the amount and density of the brine, the water supply to the capacitors, the health of emergency ventilation, the presence of the necessary spare parts, materials and tools, personal protective equipment. Special attention It should be paid to checking the condition of the rubber parts of compressors and pumps, the operation of the oil system, valves and the glands.

For the convenience of service personnel on coolant pipelines, observation lights or other devices can be monitored.

In various places of the refrigeration, nests for devices required both for continuous control of the installation, and for periodic tests. Pressure gauges, thermometers, ammeters and others measuring instruments Install so that when the installation starts, they were in the field of view of the driver and his assistant.

Automatic regulatory fittings are usually duplicated manual. This allows you to continue the production of cold at the failure of the part of automatic control devices.

Middle and large refrigeration units are mainly working with a manual start-up system. The technical operation of them is quite complex and requires deep knowledge from attendants physical bases obtaining cold, devices of machines, devices, devices, reinforcements and rules of treatment.

To facilitate the work of the personnel in the machine branches of refrigeration stations, pipeline schemes, equipment plans, information about the main parameters of refrigeration plants, refrigerant consumption rates, oil, electricity, safety posters, graphics of preventive inspections and repairs are postponed.

In order to orient the service personnel in the branched diagrams of pipelines, they are painted in conventional colors. Most often apply the following color:
For refrigerant pipelines: injection - red, liquid - yellow, suction - blue;
For brine pipelines: pressure - green, reverse - brown;
For water pipelines: pressure - blue, reverse - purple.

In the presence of several parameters of the cold on the painted pipelines, there are also conditional rings showing how this pipeline belongs to which machine.

The effective and reliable operation of any refrigeration unit depends not only on the good technical condition of the equipment, but also from the competent operation of it. Direct observation of the equipment of the equipment are driven by machines, their assistants, apparatuses, duty mechanics and electricians who subordinate to the chief of change of the refrigeration station.

The main task is to maintain the given parameters of the refrigeration machines with the lowest expenditure of energy and operational materials and the strict implementation of safety regulations.

For the successful performance of tasks facing operational personnel, needed:
