Precision air conditioners belong to high-precision technology, so they require periodic preventive measures. Maintenance of precision air conditioners, carried out on time, guarantees trouble-free operation for many years. The smallest malfunctions can lead to serious and costly breakdowns.
What is diagnosed during maintenance
In the process of regular maintenance of precision air conditioners, the following work is carried out:
- testing the operation of the entire system;
- replacement or flushing of filters;
- measurement of the freon pressure of the suction line;
- measurement of freon of the discharge line;
- suction temperature measurement;
- measurement of discharge temperature;
- setting the optimum freon pressure;
- washing the heat exchanger of outdoor units;
- condition control and cleaning of steam humidifiers.
The contract with the service company specifies the types of work and the frequency of their implementation.
List of monthly preventive maintenance work for precision air conditioners:
- external inspection of the state of integrity and degree of contamination of the units;
- listening to the operation of the compressor and fans (in the absence of extraneous sounds);
- study of microprocessor data on temperature and humidity inside blocks;
- analysis of data on malfunctions (based on microprocessor data);
- inspection of the electrical part (condition and fasteners of the wiring);
- inspection of the compressor for the integrity of the pipes, the quality of the fasteners, the presence of grease leaks;
- visual control over the condition of the fan unit.
List of quarterly maintenance work on precision air conditioners:
- cleaning the drainage system;
- washing or replacing the humidifier;
- control over isolation;
- testing the operation of the fan bearings;
- tightening the wiring connections;
- control over the contactor;
- electricity consumption testing;
- pressure testing;
- testing the state of the pressure switch valve.
Repair of precision air conditioners
Causes of breakdowns and subsequent repair of precision air conditioners:
- illiterate installation;
- neglect of regular technical inspections;
- violation of the rules of transportation;
- mechanical damage to external blocks by icicles or heavy objects.
If you notice a malfunction, do not try to repair the precision air conditioner yourself.
The longer the equipment works without technical inspections, the more expensive it will eventually cost to repair it.
Large firms provide equipment diagnostics at any time of the day, on weekends and holidays.
