Energy Savingsĭue to the ability to modulate speeds of the scroll compressor, there is a big energy saving for the homeowner. This results in better control over humidity. They can hold temperatures in a home well and match the exact need of the house. Two-stage and variable-capacity scroll compressors are known for their ability to control humidity well. This translates to a much smoother operation and less noise. This, of course, results in compression.Īgain playing into the fact that the compressor has a pretty simple motion, the compressor has less torque variation. The scroll is orbiting in a counterclockwise direction. Now, when the one scroll orbits in a small circle, it is narrowing the passageway in a circular motion from the outermost point to the center. While one scroll is quickly moving, the other scroll is staying stationary.ĭue to the geometry of the two scrolls, there is a passageway, or vane, that exists from the center to the outside – think of one of those maze games that appear on restaurants’ kid menus. The shaft will orbit quickly, making one of the scrolls also quickly orbit in a circle. There’s a small off-center shaft with a keyway in the middle of the assembly. These spirals are called scrolls, hence the name. If you can imagine two concentric spirals whose spirals are going in opposite directions, you’re off to a good start.

Scroll compressors are a mighty little invention.
Scroll compressor how to#
Let’s learn more about how they work, how to use them, some advantages of this compressor, top brands in the space, and how they benefit over the previous industry standard compressors. This novel motion lends itself to a lot of advantages over the previous industry standards, the reciprocating and rotary compressors. The big difference is the motion that the scroll compressor uses. It pressurizes, heats, and pumps air from one place to another. Scroll compressors are just another type of air compressor. They are becoming a good alternative to the previous industry standard compressors for HVAC applications. They are a type of compressor that has great use in industrial, manufacturing, and home use. Scroll compressors are also called spiral compressors, scroll vacuum pump, or scroll pump. NOTE: Refrigerant pressures are not typically used to verify the operation of the solenoid because the liquid pressure is very similar between low and high stage operation, so it should not be used for troubleshooting the solenoid.Īre you a homeowner or own a commercial property? Check out mybryantdealer.Check It Out What is a Scroll Compressor? If the coil resistance is infinite or grounded, the compressor must be replaced. The resistance should be approximately 330 or 1640 ohms depending on the unloader supplier. You can measure the internal compressor solenoid coil resistance. If you receive 24Vdc you may have a bad connection where the rectifier plugs into the compressor or the internal solenoid are defective. Verify there is 18 to 28Vac applied to the rectifier leads then check the output of the rectifier for 24 Vdc. If the expected result is not achieved, shut the compressor off and remove the rectifier from the compressor. There should be approximately 20 to 40% change in amperage. While it's running unloaded, measure the amperage of the compressor. Call for Y1 (unloaded) and let run for 15 minutes until the system is stabilized. If it is suspected that the unloader is not working, it can be verified by the following method.

When the compressor is operating in high stage (both Y1 and Y2) the 24Vdc solenoid coil is energized. When the compressor is operating in low stage (Y1 only) the 24Vdc compressor solenoid coil is de-energized. This unloading (Y1) and loading (Y2) process are accomplished by the use of an internal DC solenoid and rectifier.

The Copeland Scroll Ultra-Tech compressor has an internal bypass port, which allows the system to run at 67 percent part-load capacity and 100 percent full load. The compressor is an electrical (as well as mechanical) device, so use caution when working near compressors. Compressors are specifically designed to operate with designated refrigerant and cannot be interchanged.
