So, there is no hassle of an oil change or oil-filter change.
On the other hand, scroll compressors completely exclude the need for lubrication. Hence, there is still a chance of oil seepage through the seals, causing contamination. Even though some reciprocating and rotary compressors claim to be oil-free, they usually use oil in the gearbox. This eliminates the risk of air contamination and gives you very clean air. Therefore scroll compressors can offer you a 100% oil-free operation. As the scrolls don’t need to touch, hence no lubrication is required. Scroll compressors have a rotary spiral design. Thus it ensures enhanced durability of the compressor.Ĭonsequently, scroll compressors are very low-maintenance, which saves your maintenance cost over the lifetime of its service. Therefore, the reliability for scroll compressors is significantly higher than that of reciprocating compressors.ĭue to orbital motion in scroll compressors, the rubbing velocity is 30%-50% less than piston rings or vane type. Because of having fewer moving parts, there are fewer chances of failure. Scroll compressors basically have two moving parts: a fixed scroll and an orbital scroll. So you can see, scroll compressors give you better flexibility to choose options for exactly what your application demands. On the contrary, reciprocating or rotary screw compressors work well at specific duty cycles. Moreover, scroll compressors can perform well in both high and low duty cycles. The modulation of capacity based on the necessity ensures efficient dehumidification, better air quality, and low utility cost. They run continuously and blow cold air at a steady stream.

Depending on the need of the house, they can either run at full capacity or a more efficient speed. Two-stage units can operate at two levels of speed: high and low.They run at full blast and usually used for cooling or heating homes efficiently. Single-stage units are simple, inexpensive, and operates at only one speed.They can be either single-stage, two-stage, or variable capacity units. Scroll compressors offer various designs and a wide range of operations.
If you consider your summer utility cost, that saves you a lot of money! The internal construction as well as the compression mechanism also contributes to lower power consumption.Īs they have fewer moving parts, they are more energy-efficient!Ī scroll compressor can reduce the consumption of electricity up to 30% compared to conventional compressors. Note that the cooling capacity was still 5% higher for the scroll compressor!Īs mentioned earlier, the scroll compressor’s ability to modulate capacity as necessary can save energy. A study reports that the power consumption is 25.3% lower for scroll compressors compared to the reciprocating type.When the operating speed increases, the efficacy may reduce, still the scroll compressor performs better than the rotary compressor. A report shows that a scroll compressor with optimum dimensions can have mechanical efficiency similar to a rotary compressor.This means the efficiency of the scroll compressor to compress gas is much higher than the reciprocating compressor (58%-66%). Across the full range of speeds, the volumetric efficiency of the scroll compressor can range from 89% to 94%.Its higher efficiency and cooling capacity make it a great option to use even in refrigerators!ĭon’t just take my word for it! Let’s look at some research statistics: The scroll compressor has a compact, yet a brilliant design that can cool a large amount of air much faster than most other compressors.
