Great content, but a correction, the oil becomes low viscosity as it is heated, at low temperature oils have higher viscosity. For example water has a viscosity of around 1 centipoise, while table oils have viscosity in the dozens or hundreds of centipoises, while Tar has a viscosity in the billions.

Sir Thanks for videos.
(1) Can you explain lubricant system in screw chiller compressors.
(2) Can you explain how water chillers different with brine (minus degrees) chillers. Sir, you should also make a videos on minus degree chillers

Is there any chance that the oil gets mixed with the refrigerant and oil then circulates into the system with the refrigerant and probably, lower the efficiency? Kindly illustrate that point and what will happen then? Also, how to prevent it?

To take out refrigerant from oil sump one copper pipe is connected to the suction of the compressor. Since the suction in compressor occur at low pressure how the oil does not go along with refrigerant to the compressor?

Thanks for another great video! Any coming on economizers, flash tanks, etc? Using approach, water side piping/valving/bypass configurations?

Will the lubricant in contact with the refrigerant gas? Is it necessary to have a compatible lubricant type to cope with the refrigerant?

Sir, there are two gauges one for high pressure and other low pressure on chiller. What is this represents? Is this oil pressure

Can you please explain a reciprocating chiller in detail. That will help many people to pass MRO exam for NYC. Thank.

5: 20, why the oil return from compressor thrust bearing was not returned back to Oil sump for pressurisation?
