How to recover the refrigerant from an industrial chiller to the receiver?

During the maintenance or servicing of industrial chillers, it is necessary to recover the refrigerant before proceeding with subsequent maintenance work. There are two common methods for recovering refrigerant from industrial chillers: one is to recover the refrigerant into a receiver, and the other is to recover it into a refrigerant cylinder. 1. How to recover the refrigerant from an industrial chiller into a receiver? Note: Our industrial chillers are equipped with high/low pressure controllers. When recovering refrigerant, the contacts of the high/low pressure controllers should be kept normally closed to prevent the machine from shutting down due to pressure issues during refrigerant recovery. The refrigerant of the industrial chiller should be...

How to recover the refrigerant from an industrial chiller to a receiver or cylinder?

1. How to recover the refrigerant of an industrial chiller into the receiver? The specific steps to recover the refrigerant of an industrial chiller into the receiver are: 1. Open all valves of the industrial chiller refrigeration system, and turn the suction shut-off valve counterclockwise to fully open it, then use a multi-purpose connector to connect the service valve with the suction shut-off valve. 2. Close the service valve and adjust the suction shut-off valve to the three-way position; 3. Turn clockwise to close the outlet shut-off valve of the receiver; 4. Start the refrigeration compressor of the industrial chiller, and the main refrigerant in the evaporator will be drawn into the condenser and receiver. 2. How to recover the industrial chiller

Precautions for the maintenance and repair of evaporators

Maintenance and Repair of Evaporators (1) Maintenance of Evaporators 1) Regularly perform leak detection on the evaporator. Leakage is a common fault in evaporators, so frequent leak checks should be conducted during use. When an ammonia evaporator leaks, there is a pungent odor, and the leak area does not frost. Phenolphthalein test paper can be used to check the leak because ammonia is alkaline and turns the test paper red. Visually, the leak point is usually where there is no frost on the evaporator. Soap water can also be used to find leaks. For Freon evaporators, leak detection can be done using a halogen lamp and halogen leak detector, or by using soap water to find leaks. During inspection, first visually check the evaporator

How a filter works

How a filter works

The working principle of the filter is: when the filter is operating, the water to be filtered enters through the nozzle, flows through the filter screen, and then exits through the outlet used for the process cycle into the pipeline required by the user. Particulate impurities in the water are trapped by the filter mesh. With this continuous cycle, more and more particles are captured, and the filtration speed gradually slows down.

The function of the filter

The function of the filter is to remove suspended solids and particles from the water, reduce turbidity, purify water quality, and decrease the formation of system dirt, bacteria, algae, and rust, thereby purifying the water and protecting other system equipment to operate normally.
