Water Cooled Screw Chiller Cleaning Process
- Oct 25, 2017 -

The selection of chillers should be considered according to the cold load and use. Water Cooled Screw Chiller For the low load operation time of the refrigeration system, it is advisable to choose the multi-head piston compressor Group or screw compressor group, easy to adjust and save energy.

The unit with higher performance coefficient is preferred when choosing chillers. Water Cooled Screw Chiller According to data statistics, the general chiller operating time of the year under 100% load accounted for about 1/4 of the total operating time. The running time of 100%, 75%, 50% and 25% load in total running time is approximately 2.3%, 41.5%, 46.1%, 10.1%. Therefore, Water Cooled Screw Chiller in the selection of chillers should be given priority to the efficiency curve relatively flat model. At the same time, the adjustment range of the water chiller load should be considered when designing and selecting. Multi-head screw chillers have good partial load performance and can be selected according to the actual situation.

Screw chillers because of its key components-compressors using screw-type so-called screw chillers, the unit by the evaporator out of the state of the gas refrigerant, after the compressor adiabatic compression, into a high-temperature high-pressure state. Compressed gas refrigerant, in the condenser, Water Cooled Screw Chiller such as pressure cooling condensation, after condensation changes into liquid refrigerant, and then through the throttle valve expansion to low pressure, into a mixture of gas and liquid. Water Cooled Screw Chiller In which low-temperature low pressure liquid refrigerant, Water Cooled Screw Chiller in the evaporator to absorb the heat of the cold matter, and then become gaseous refrigerant again. The gaseous refrigerant enters the compressor through the pipeline and begins a new cycle. Water Cooled Screw Chiller This is the four processes of a frozen cycle. It is also the main working principle of screw type chiller.

The cleaning process of the screw chiller is as follows: First, the cleaning agent is injected into the liquid tank, then the pump is started to run and the cleaning is started. The cleaning is carried out in a positive, reverse operation, until the cleaning agent does not show acid. For mild pollution, just circulate about 1 hours. And seriously polluted, it takes 3-4 hours. If a long time cleaning, cleaning agent has been dirty, filter also blocked dirty, should replace cleaning agent and dry filter after this operation. After cleaning the system, Water Cooled Screw Chiller cleaning agent has been dirty, the filter is also blocked dirty, in the liquid reservoir cleaning agent to be recovered from the liquid pipe.

Lubricating oil on the main function of the compressor is lubrication, cooling and capacity adjustment, it is recommended that every 3,000 hours in the cold water machine should be checked once the clean lubricating oil, each run 6,000 hours or every 1 years should replace lubricating oil. Water Cooled Screw Chiller When changing lubricating oil, the oil should be selected through quality certification.

Operators should always pay attention to the use of units, if the cold water machine abnormal sound or failure, must first turn off the machine in time to prevent two damage to the unit. And according to the Cold Water Machine Control Panel failure to troubleshoot, in the failure has not been ruled out, remember not to start chillers.
