The preparation of the combined air -conditioning unit before trial operation
Before the trial transportation of the combined air -conditioning unit, it is necessary to prepare well to prevent adverse effects on the air -conditioning system.Therefore, the fan cannot be started at will.
In terms of structure, combined air conditioners, in addition to heat exchanges, filters, and humidifiers, the main equipment is a fan.The combined air -conditioning unit and the fresh air unit should pay attention to the following matters before testing:
Before the trial movement, the environment of the internal and external and machine rooms of its unit must be cleaned. The internal air -conditioning air -conditioner that is used for air must be completely wiped to prevent the clean ducts from being polluted again.
The cleaning system combined air conditioner for cleaning systems with a high degree of cleanliness has a leakage requirements. First, check the leakage and then conduct trial transportation of the crew.
When the crew of the crew, the air -to -air return, and the new air outlet are installed with an electric regulating valve, it should be operated before the fan test operation. Each electric regulating valve should be flexibly switched and switched.
The humidifier must make corresponding preparations before the operation of the combined air -conditioning unit is running. The program and methods of the trial transportation must be correct. Otherwise, various faults will occur during the trial operation and cannot be humidified normally.The humidifier should be carried out in accordance with the corresponding rules during operation.
Corresponding preparations should be made before the running wheel heat exchanger. In addition to the normal operation of the group, the efficiency of the heating should also reach the requirements of the equipment technology file.
Pay attention to the following matters when trying the rotation of the turntable heat exchanger:
1. The air -conditioning systems air volume experiment adjustment has been completed, and the new air volume and exhaust volume should be equal.
2. When the full heat exchange is required for thermal recycling during the transition season, the exhaust volume must be bypass.
3. In order to prevent the exhaust volume from leaking into the fresh air system, it should be inspected and the wind pressure on the new wind side should be greater than the wind pressure on the exhaust side.
4. In order to protect the turntable and extend the service life, the rotor and the exhaust volume are chain.
5. Under the conditions of winter conditions, when the unit trial transportation, the operating status of the new wind preheating system should be checked to prevent frost or thawing on the surface of the turntable, resulting in reduced efficiency, plugging eye blocks, and even damaging the rotor.
Before using the combined air -conditioning unit, do a good job of trial operation of the combined air -conditioning unit, can find problems in time, solve problems in time, and effectively solve the various problems in the air conditioning unit.Ensure its quality.
The above is the preparation work before the trial movement of the combined air -conditioning unit and the matters that need to be paid attention to
