Propane screw refrigeration compressor
Thread Content
For a 100,000 m³ natural gas liquefaction plant, what impact does the oil supply temperature have on the refrigeration efficiency of the propane screw refrigeration compressor?
The oil supply temperature of propane screw refrigeration compressors affects the cooling performance. Excessively high temperatures can cause the viscosity of the lubricant to decrease, affecting the lubrication effect and the efficiency of the compressor ； Temperatures that are too low may increase the viscosity of the lubricating oil, thereby increasing energy consumption and reducing cooling efficiency. Therefore, properly controlling the oil temperature is important to ensure the efficient and stable operation of the refrigeration system. .
The instructions for use should be read carefully to understand the principles of the mechanical structure and the physical and chemical properties of the medium... for reference.
The oil temperature should be controlled primarily in accordance with the supplier’s guidelines; theoretically, it has no impact on the cooling efficiency. (There is an oil temperature interlock.) It is mainly related to the inlet and outlet pressures (throttle valve opening), as well as the cooler and the load
