How to use central air-conditioning air-cooled water unit
One of the more prominent problems in the central air-conditioning water system is hydraulic imbalance. For some large-scale and more complex systems, there are usually many control loops. Due to the different sizes of loops and different lengths of pipelines, hydraulic imbalances will occur if you are not careful.
Central air-conditioning water chillers are frequently used in summer, so people can enjoy the coolness without leaving home. Then, how to use central air-conditioning air-cooled water chillers? Is the method you master correct? Let's look at the introduction.
Central air-conditioning air-cooled water unit
There is an outdoor unit condenser in the central air conditioner. When we use the central air conditioner, we must first ensure that there are no fallen leaves, lint, insects, slag shells and other pollutants in the condensation stage. The presence of these pollutants will cause power consumption Increase in volume and damage to the air conditioner. When removing dirt, use a vacuum cleaner.

Since the cooling (heating) water unit of the central air conditioner is generally used in summer, the manufacturer will require the unit to turn on the antifreeze device in the winter when designing, and the unit should be energized for a long time as required. It is generally safe. If there is a power failure In this case, the anti-freezing device is invalid. If the outdoor temperature reaches below zero at this time, the outdoor host should be kept warm in time. The moisture in the air conditioner should be drained. If the unit has been shut down for a long time before use, the unit should be energized first, so that the heating device of the compressor preheats the compressor, and the power-on time is not less than 6h (the power-on time in winter is longer) before the compressor can be started.
When the central air conditioner is used in summer, the temperature should be adjusted properly. Generally, it should not be too high or too low, as long as it is comfortable. It is recommended that the cooling is 23~28OC, and the heating is 18~23OC. The indoor fan-coil return air filter should be removed and cleaned regularly to ensure that the fan-coil is working properly. Frequently check whether the water supply and exhaust devices of the water system work, the power supply and electrical system of the unit, and whether they are normal to prevent air from entering the system and causing water circulation. The reduction or the difficulty of circulation, which affects the cooling and heating effect of the unit and the reliability of the unit.
