Precision air conditioners are high-precision technology, so they require periodic preventive measures. The maintenance of precision air conditioners, carried out on time, guarantees uninterrupted operation for many years. The smallest faults can cause 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;
- replacing or flushing filters;
- suction line freon pressure measurement;
- measurement of freon discharge line;
- measurement of suction temperature;
- discharge temperature measurement;
- setting the optimal pressure of freon;
- washing the heat exchanger of outdoor units;
- monitoring and cleansing steam humidifiers.
The contract with the service company stipulates the types of work and the frequency of their implementation.
The list of monthly preventative maintenance of precision air conditioners:
- external inspection of the state of integrity and degree of contamination of the units;
- listening to the compressor and fans (in the absence of extraneous sounds);
- study of microprocessor data on temperature and humidity inside the blocks;
- analysis of data on malfunctions (based on microprocessor data);
- inspection of the electrical part (condition and wiring fasteners);
- inspection of the compressor for the integrity of the tubes, the quality of the fasteners, the presence of lubricant outflows;
- visual control over the condition of the fan unit.
The list of quarterly maintenance work for precision air conditioners:
- drainage system cleaning;
- washing or replacing a humidifier;
- isolation control;
- testing the operation of fan bearings;
- pulling up wiring connections;
- contactor control;
- electricity consumption testing;
- pressure testing;
- testing the state of the pressure switch valve.
Repair precision air conditioners
Causes of breakdowns and subsequent repair of precision air conditioners:
- illiterate installation;
- neglect of regular inspections;
- violation of the rules of transportation;
- mechanical damage to external blocks by icicles or heavy objects.
If malfunctions are noticed, you should not try to repair the precision air conditioner yourself.
The longer the equipment runs without inspection, the more expensive it will ultimately cost to repair.
Large firms provide equipment diagnostics at any time of the day, on weekends and holidays.
