Ceiling air -conditioning crew is a common air -conditioning equipment that is usually installed in the ceiling mezzanine, which has the function of reducing indoor temperature and humidity.In order to ensure its normal operation and extension of the service life, daily maintenance and maintenance are needed.Here are some suggestions:
1. Make sure that the installation is correct: The ceiling air -conditioning unit should be installed horizontally in the ceiling mezzanine to ensure that the side of the condensed water pipe is allowed to be less than 5%, but it is not allowed to be higher than 5%to ensure the smooth discharge of condensate water.
2. Maintain the surrounding environment: There should be sufficient maintenance space around the unit to facilitate daily maintenance and maintenance.
3. Check condensate water emissions: The condensation water discharge connected to the unit must have water seal, and the water seal should have sufficient height to prevent water seal loss.
4. Check the water pipe connection: The water connection pipe of the surface cooler is in and out, and the water inlet should be installed with the deeper valve and filter.The water pipe connected to the crew should be connected to the winding. The torque should not be too large when taking off, so as not to lose the loss of the heat exchanger.
5. Check the power connection: The power supply of the unit is 380V, 50Hz.The power supply can be connected to the motor only when the power is met.After connecting the power, check whether the fan turns correctly.If reversal, stop and change the order of power.
6. Maintenance of wind motor: The fan motor should be well grounded, and there are reliable protection such as overloading, overheating, and defects.
7. Check the hot and cold medium: The hot and cold medium of the ceiling air conditioner should be pure soft water, and the work pressure must not exceed 1.6MPa.
8. Regular exhaust: The water outlet pipe is equipped with an exhaust valve.Before running and hot and cold conversion, the exhaust valve should be opened, and the air in the heat exchanger and the air in the pipeline should be discharged to avoid affecting the heat exchange effect.
9. Control temperature: Ceiling air -conditioning device for summer for cold water is not less than 5 ℃ Winter heating temperature should not be greater than 80 ° C to ensure the normal operation of the equipment.
10. Start in winter: When the cold area and the new air system ceiling air conditioner opens the system in the cold area and the new air system ceiling air conditioner, first turn on the electric heater for 5-10 minutes, and then re-start the ventilation to avoid a large amount of strong cold air produced in the heat exchanger.Ice plugs; the fresh air system valve should be turned off first when stopping, and the electric heating heater ceiling air conditioner is better turned off.
11. Long -term shutdown: Ceiling air -conditioner should not be used for air storage in the dish storage water in the dish storage in the pipe when it is not used for a long time in winter.If it is not running temporarily in winter for a period of time, there should be a hot water circulation in the tube to prevent rust prevention.
12. Regular cleaning the filter: The filter should be cleaned regularly to ensure the use of the unit.If the air volume is found, it is generally caused by too much dust in the filter.
The above is the steps and precautions for the running and maintenance of the ceiling air -conditioning unit. When the crew fails, it is timely to find a professional to repair the barrier to ensure that its normal operation and extend the service life.
