Pipelines Sizes
Line size and layout of the cooling system should be done properly if the system will work correctly and efficiently.
Refrigerant piping shall be designed and installed so as to diat:
- Minimizes pressure losses in the piping. The pressure drops, happens every time when the liquid flows through the pipe, so it is inevitable. However, excessive pressure drops unnecessarily reduce the capacity and efficiency of the cooling system.
- Provides continuous oil return into the compressor crankcase. If the oil can't go back to the crankcase of the compressor will overheat and be destroyed.
- Prevent ingress of liquid refrigerant die compressor at start or exploitation. Liquid pools or collects in the system of pipelines and suddenly flies towards the compressor from moving pairs can damage valves and pistons or wash die lubrication of bearings.
- Avoid trapping oil in the suction or discharge lines. This slug lubrication can also cause damage to the components in the system.
- Ensures an adequate supply of refrigerant all evaporators.
If insufficient supply of refrigerant delivered to the evaporator, die temperature controlled space will increase.
Many operational problems encountered in refrigeration can be traced to improper design or installation of the system's pipelines. Therefore, the proper procedures used to minimize these problems are described in detail in the following subsections...
