When using water-cooled chillers, what should be paid attention to when maintaining the air conditioner host?

(1) Ensure that the environment around the water-cooled chiller is clean, and regularly check whether the air-conditioning installation device, control center function is abnormal, whether the starter and relay are operating normally, and whether the compressor is in good operating condition, etc. Regularly check the condition of the shaft seal, check the water system of the chiller, the heat exchange effect, and the refrigerant charge of the unit. Check the airtightness of the unit and the condition of the interlocking device of the accessory components of the unit. When maintaining and inspecting the main unit of the air conditioner, first close the gate valves at both ends of the oil filter, and then use the air pipe to drain the air into the barrel. For the exhaust valve, slowly increase it.

(2) For the air-conditioning main unit of the water-cooled chiller, under normal circumstances, the temperature of the outer oil pipes of the two gate valves of the oil filter should be almost the same, or the temperature of the oil filter should be higher! After the air-conditioning main unit is exhausted, use special tools to carry out After disassembling, move the filter manually to check whether the pressure is completely relieved. 、During the process of disassembling and installing the filter element, you should not put your hands on the bottom. Place your hands on both sides correctly. Take out the original filter element, clean the filter case, and replace with a new filter element. Check the sealing ring, install the filter, and open the gate valve at the separator side for about 20 seconds. Keep the gate valves open at both ends to check the airtightness of the filter.

1. Water-cooled chiller explosion-proof units need to use water pumps and cooling towers, and water will be used. The high-pressure alarms of the unit are often due to water quality problems or when debris enters the unit during use, high and low-pressure alarms will appear. , How should we deal with the above problems? The basic reason for the high-pressure alarm of the water-cooled chiller is poor water quality. Impurities have entered the water supply hole and hindered the cooling effect of the cooling tower. We should remove impurities, check the water quality, and do a good job accordingly. The treatment work prevents impurities from entering the cooling water tower.
