Following Injuries, Employers Must Remember to Fill Out the Paperwork

On-the-job injuries can be stressful for everyone who was involved or witnessed an accident. But no matter how upsetting or time-consuming the situation, employers must remember to fill out the paperwork afterwards for the Occupational Safety and Health Administration (OSHA).

Are You Shorting Your Employees on Overtime?

Despite revisions to the Fair Labor Standards Act in 2004, determining how to properly classify workers remains an ongoing struggle for many companies.

Reward Employees for Their Good Work

Rewards are a powerful method for encouraging good job performance. Good work may not be repeated and employees can upset customers when managers don’t recognize, encourage, and reward them for job performance that meets or exceeds customers’ expectations. But rewards must be used effectively.

Are You Safe From Your Company’s Drivers?

If your employee is involved in an accident while working, you can be held liable. Where a company knew or had a reason to know that a driver of its commercial vehicles could create a risk of harm to others, it creates a “negligent entrustment.” And the stakes can be high.

The Breakthrough of the Scroll Compressor

October 15, 2007



The first Copeland Scroll® rolled off the production line in 1987, and the cooling industry was changed in a way that would benefit contractors and their customers in many, many ways. The prime benefits have been efficiency and product reliability.

Many features of the Scroll focus on preventing compressor failures, but the Scroll’s primary design also improves efficiency and reliability thanks to its classic, concentric compression scroll, in which one spiral-shaped part fits into another; the space between the two parts contains crescent-shaped gas pockets.


CLASSIC SCROLL OPERATION

In operation, one Scroll is fixed in place while the other orbits within the first. The refrigerant gas is drawn in by the movement and forced toward the center of the scroll through successively smaller pockets, thereby increasing the gas pressure until it reaches its maximum pressure. Then it’s released through a discharge port in the fixed scroll.

Copeland Scroll compressors are unique in the industry because they feature both axial and radial compliance in their design, whereas other scroll models utilize a mechanically fixed design and scroll tip seals.

Axial compliance refers to the ability of the scrolls to separate in the axial — or vertical — direction remaining in continuous contact around an axis, in all normal operating conditions, ensuring minimal leakage without the use of tip seals. Radial compliance refers to the ability of the scroll flanks to separate. These features of the Scroll design allow the compressor to be more tolerant of liquid refrigerant or debris than other technologies, making for a compressor that is extremely durable and reliable.

The combination of axial and radial compliance means that Scroll compressors actually “wear in” rather than wearing out. Continuous flank contact, maintained by centrifugal force, also minimizes gas leakage and maximizes efficiency of the compressor.

Next month: Tech Tips will begin examining the Scroll’s improved reliability through its oil control system.
