The operation of screw compressor unit
The standard operation of a screw compressor unit is an important step to ensure the unit works well and has a long service life. Below lists are the steps: 1. Refrigerant gas charged. The screw compressor unit needs to charge refrigerant on site. The refrigerant quantities and type must be in accordance with the regulations. Before charging, the quantities of refrigerant should be enough. In these cases, when the refrigerant charge is insufficient, it will lead to insufficient cooling capacity. When the refrigerant charge is too large, it will not only increase the cost but also have a negative impact on the operating energy consumption. 2. Operation of the screw compressor unit After the finished refrigerant is charged, we need to power on to operate and set the unit. During operation, bellows need to notice. (1) Check if all valve on the compressor unit is opened completely. Especially the discharged valve. (2) For water-cooled or water chiller unit, please open the conde...
