Compressor installation precautions for screw chiller

次 Source: Shenzhen Simpson Refrigeration Technology Co., Ltd. Release time: 2019-03-05 Browse: 1022 times

Back to list
When the working system of the screw chiller is used to restrict the compressor to be installed in a small enclosed space, its ventilation environment must be considered. It must be equipped with extraction and exhaust equipment to facilitate air circulation. The capacity of the extraction and exhaust equipment must be greater than the capacity of the cooling fan of the compressor, and the location of the exhaust inlet must be suitable for the location of the hot exhaust outlet of the compressor. Note for compressor installation of screw chiller:


1. The compressor should use a unit with a large bearing capacity, and the operating speed and acceleration should be limited to the permitted range.


2. Try to install the compressor of the screw chiller in a cool, clean and well-ventilated place to ensure that the air around the compressor is clean and the moisture content is minimized.


3. Compressed air is not allowed to contain flammable gas and corrosive gas, otherwise it may cause built-in explosion or internal embroidery.


4. The air-cooled machine should preferably have an exhaust fan or air duct to lead the hot air out of the room, and avoid hot air circulating to the air inlet.


5. This machine uses three-phase AC power 380V, 50Hz. The power supply line of the guide compressor must match its power and be installed with safety devices such as air switches and fuses. To ensure the reliability and safety of electrical equipment, it must be reliably grounded.




The new machine commissioning of screw chiller should be commissioned by a commissioning technician designated or approved by the manufacturer. The compressor must not be operated at an exhaust pressure higher than that specified on the nameplate, otherwise the motor will be overloaded and burned out. When the screw chiller is running, strictly check the compressor's running direction. When it is found that the reversal should stop immediately, cut off the power, reverse any two phases of the three-phase line and restart the machine, otherwise the compressor of the screw chiller will be damaged ( Please pay attention to every factory power overhaul!)
