What should be noticed in the operation of industrial chiller units?
Please check whether the LC -25°C ~ -5°C Low Temperature Chillers is damaged during installation and select a suitable place for installation and future maintenance.
The installation site of the unit must be the floor, installation pad or foundation, with its levelness within 6.4mm, and can bear the operating weight of the unit.
The unit shall be placed in the machine room with a room temperature of 4.4-43.3 ℃, and there shall be enough space around and above the unit for daily maintenance.
At one end of the unit, the extraction space for cleaning the condenser tube bundle shall be reserved, and the door hole or other suitable holes can also be used.
Select the water pipe with proper diameter, cooling system and cold water system when the unit operates at maximum power, and connect them correctly.
For ordinary applications, the water flow speed through the evaporator and condenser is allowed to be between 1.0-3.6m/s.
The water flow shall be stable under any load.
1. Maintenance of industrial water chillers.
Due to the high operating pressure of air-cooled units, they are generally installed outdoors, and the operating environment is relatively poor. They are not as good as water-cooled chillers in terms of maintainability and reliability.
If the machine has problems with alarm or convenient temperature control, engineers need to be sent to visit and repair it according to the site conditions. Therefore, the maintenance costs of water-cooled chillers and air-cooled chillers also depend on the specific situation.
Air-cooled water chillers and water-cooled water chillers are widely selected in the industrial refrigeration industry. When purchasing water chillers in the actual factory, it is still necessary to consider whether to choose air-cooled water chillers or water-cooled water chillers according to all factors such as different use environment, temperature control range, required cooling capacity, heat dissipation, etc.
2. How to maintain the industrial water chiller?
Check whether the voltage of the industrial water chiller is normal, whether there is phase loss, and record the unit operation data, including high pressure, low pressure, operating current, temperature control, etc.
Every month, check whether the oil level and temperature are normal, and whether the compressor has abnormal sound or vibration. (Note: the high pressure display is 11-17kg, and the low pressure display is normal within the range of 3-5 kg)
The condenser should be cleaned regularly every year, and the water-cooled industrial water chiller should also remember to clean the cooling water tower and the cooling water pipe, and check whether the water quality of the water source has become dirty or foreign matters.
If the water quality is too poor, the water should be treated first. In addition, industrial water chillers are equipped with drying filters and expansion valves, which should be replaced in a timely manner in case of blockage.
