Chiller Condenser water system in District Cooling Hindi/ Urdu Part- 6

The condenser is collecting all the unwanted heat from the building and transferring it over into the condenser water loop where it will be rejected from the building via the cooling tower.
The refrigerant and water never meet or mix, they are always kept separated by a metal wall, only heat transfers between them.
Under the shell of the condenser, we have multiple tubes inside. These run from one end to the other. The tubes contain condenser water. On the outside of the tubes is the refrigerant which is coming from the compressor.
As the hot refrigerant comes into contact with the cooler surface of the condenser tubes, the refrigerant is going to condense into a liquid on the surface of the tube.
If the refrigerant is the same temperature as this return condenser water then the chiller will not be able to reject any heat that’s been picked up in the building, and so the building will be unable to cool down.
Equally if the cooling tower is unable to reject the heat that’s being sent up to it, then it’s going to return at the same temperature the water is just returning straight back down into the condenser, then you will not be able to reject any heat from the compressor and it will eventually cause the chiller to trip on high pressure.
Fouling occurring on the inside of the condenser water pipework and the condenser heat exchanger. Dirt and other particles will collect on the surfaces of the pipes and heat exchanger and will form a layer of insulation.
This build-up is basically small deposits of salt, scale, dirt, mineral build-up and also bacterial growth. As I said it insulates the pipe which reduces the chiller's efficiency and cooling capacity. This can be treated with a rigorous chemical dosing regime.

Well explained, waiting for next

Which chemical using for cleaning 🧼

Sir, How can you prevent surge?? Even though condenser entering temperature is on higher side.

If coling tower max speed you can reduce the percent load of your compressor,
