Rotary Piston Compressor: Operation, Advantages, Disadvantages and Maintenance

Refrigeration is an important industry that includes many specialised products, including rolling piston compressors. This text will cover the operation, advantages, disadvantages and maintenance of rolling piston compressors.

Rotary Piston Compressor Function and Operation

A rolling piston compressor is a type of reciprocating compressor used in refrigeration systems and heat pumps. Unlike other types of compressors such as the scroll compressor or reciprocating compressor, the rolling piston compressor, also called a rotary compressor, uses two rotating elements to draw in and compress the refrigerant. The rolling pistons rotate in a sealed housing, creating a continuous compression cycle.

Rolling piston compressors can compress the refrigerant to low or medium condensing pressures and are therefore able to compress small amounts of gas in an energy-efficient manner.

Advantages and Disadvantages of Rotary Compressors

While rolling piston compressors have some advantages, they also have some disadvantages. One of the main disadvantages is the higher purchase price compared to other types of compressors. Maintenance costs can also be higher, as rotary piston compressors can be more sensitive to dirt and contamination. In contrast, however, the rotary piston compressor has a longer service life, which can lead to savings in total cost of ownership.

Double Rolling Piston Compressor

A further development of the rolling piston compressor is the twin rolling piston compressor. As the name suggests, this compressor has two rolling pistons that rotate in opposite directions. This achieves a higher pressure and improves efficiency. In this case too, the purchase costs are higher than for a conventional rotary lobe compressor, but the savings in operating costs can certainly outweigh the higher costs.

By using two rolling pistons rotating in opposite directions, a higher pressure is achieved. This means that the twin rolling piston compressor is able to compress more refrigerant than a conventional rolling piston compressor. The higher efficiency results in better efficiency and performance, which is particularly advantageous in applications with high cooling capacity requirements.

Another advantage of the double rotary piston compressor is the improved stability during operation. The counter-rotation of the rollers ensures better alignment and greater stability in operation. This is particularly advantageous in applications with high loads and frequent operation.

Service Life and Maintenance of Reciprocating Compressors

The service life of a reciprocating compressor depends on many factors, including the quality of the compressor, the operating conditions and maintenance. To maximise the service life of the compressor, it is important to carry out regular maintenance work.

Tips for Maintaining Rolling Piston Compressors to maximise service life

Regular maintenance can help extend the life of a rotary compressor. This includes cleaning filters, filter driers and heat exchangers, checking electrical connections and checking oil level and quality. It is also important to check the refrigerant regularly and replace it if necessary. Maintenance should be carried out according to the manufacturer's instructions.

Recommendations for Regular Maintenance Work

Regular maintenance of compressors usually includes the following steps:

  • Checking the electrical Connections and Components
  • Cleaning Filters and Heat Exchangers
  • Checking the Oil Level and Oil Quality
  • Check the Refrigerant and Replace if Necessary
  • Checking the Vibration and Noise Levels
  • Check Wear Parts and replace if Necessary

The exact Requirements and Intervals may vary depending on the Manufacturer and Model.
