The team spent that year meticulously inspecting the issues and eliminating the elements that gave rise to concerns, which allowed them to finally reach the launching stage. Extensive discussions were held within the project, and the company finally decided to extend the time allotted for development by one year. Although the prospect of commercialization was assured, the development deadline, which had been extended due to the inability to completely eliminate unstable elements relating to quality control, drew near once again, and the company was forced to decide whether or not to proceed with the launching of the product. World’s First Commercializationįive years had already passed since 1985, surpassing the period originally set aside for development. If it were not for this feat, we would not have been able to move forward with development we consider this mechanism to be the greatest invention that made the oil-free version possible. We also managed to add a mechanism that made the clearance of the rotating scroll easily adjustable. This was considered difficult to achieve with the oil-free methods that existed at that time, but we came up with the world’s first pin crank mechanism, and succeeded in creating a stable and highly accurate rotating motion. The most difficult issue was in creating the rotating motion typical of the scrolls. There was no rulebook regarding the development of an oil-free scroll compressor, since no one had done it before, so our team continued to grope in the dark for clues. We began developing oil-free scroll compressors in order to overcome these issues. ![]() ![]() With our continued attempts at refining our technology, we succeeded in developing an oil-free piston compressor, but as with other competing products, it required maintenance around the piston ring every 2,000 to 3,000 hours, which presented an obstacle in popularizing oil-free compressors. Oil-lubricated compressors were the norm in the 1980s, and our main products consisted of oil-lubricated piston compressors as well.

McDevitt Air has over 35 years of HVAC experience. You can sleep with no interruptions, and you can watch TV or talk to friends or family without struggling to hear over your HVAC system. You’ll notice a low hum when your scroll compressor is working, but it won’t be as loud as the sounds from a typical piston compressor. They don’t have any noisy valves, and they produce less vibration. Since scroll compressors have few moving parts, they’re much quieter than other heaters and air conditioners. If you forget to change your air filter, dust, dirt, and other pollutants won’t cause a malfunction as easily as they would with a conventional compressor. As the scrolls become worn, they fit together better and keep more air or refrigerant from escaping. Scroll compressors don’t have as many moving parts as other types of compressors, so breakdowns are less likely. Modulating capacity in small increments with a two-stage scroll compressor means you’ll enjoy more consistent temperatures throughout your house. A system that is 100% on or off will produce noticeably cool air when on and you may feel warm when it’s been off for a bit before it comes back on. Two-Stage Scroll CompressorsĪ two-stage scroll compressor allows your system to modulate the speed of the compressor from 25% to 100%. A small scroll compressor can produce the same amount of hot or cool air as a larger piston compressor so you can save valuable space as well. Department of Energy suggests that heat pumps with scroll compressors can produce air that is 10 to 15 degrees higher than air from standard piston compressors when in heating mode. A scroll compressor for your HVAC system can save more energy, last longer, and keep your home quiet.Ī heat pump or air conditioner with a scroll compressor can help you save energy and lower your utility bills. Scroll compressors are more efficient than standard compressors that use pistons. This compresses air or refrigerant for your HVAC system by pushing it toward the center of the scrolls. One scroll uses an electric motor to rotate around the other. Scroll compressors have two identical spiral-shaped or scroll-shaped parts. How can scroll compressors improve the performance of your Hilton Head, SC home’s HVAC system? Keep reading to understand more about the benefits of this type of compressor.
