Seven Tips for a Healthy Computer

DECATUR, Ga. — Whether we are part of a small business, a large corporation, or are just trying to find information online at home, we seem to spend just as much time fixing “issues” and “conflicts” on our computers as we do working on them. For the home user this is merely an inconvenience, but to a business it can add up to tens of thousands of dollars lost to decreased productivity or service/repairs.

Although the mere thought of trying to “fix” a computer would cause a cold sweat to break out in most of us, it is in fact the simple little things that even the most timid technophile could prevent, which cause the majority of our desktop woes.

“Malware, viruses, identity theft, and spyware account for about 80 percent of all computer issues resulting in downtime,” stated IT guru Chip Reaves. “It is estimated that the lost-productivity cost due to these alone is around $50 billion, and the associated IT costs of dealing with it has skyrocketed from $20 billion to $198 billion in the last five years.”

That is a lot of money and a lot of work-time lost. But Reaves, the national director of Computer Troubleshooters, explains that there are seven simple tips everyone could adhere to — businesses and individual computer users alike — that will keep our computers (and wallets) in tip-top shape.

1. Old Hardware: “Studies have shown that the likelihood of physical problems with computer equipment goes up significantly after 24 to 36 months,” said Reaves. “Consider replacing computer systems every three years — considering how inexpensive computers have become, one major repair bill could easily cost more than purchasing an entire new system.”

2. Power Protection: “Surges and power drops can cause data loss and are always damaging to sensitive components, reducing their lifespan. Most people do use surge protectors, but what many don’t realize is that surge protection wears off over time. For the best protection make sure that the surge protectors for all your computer equipment are replaced every two to three years.”

3. Illegal Software: “Many businesses don’t realize that they don’t ‘own’ software; just the licenses to use it on a specific number of PCs. Many software programs automatically report their usage via the Internet, and breach-of-license letters and audits from software manufacturers to businesses are on the rise.”

4. Training: “Having to spend money training your staff might sound like a waste, but most employees understand less than 20 percent of the software packages they use. The gain in productivity far outweighs the training costs,” Reaves said.

5. Firewall and Security: “The Internet is full of hackers who regularly try to access computers for nefarious purposes. If they get in (either directly, or with the help of exploits from malware or viruses) the list of problems they can cause is pretty big, including stealing files or customer records, and deleting important data. It’s important to be sure that all computers in your organization are updated with the latest security patches from Microsoft or Apple, and that firewalls are installed and maintained properly.”

6. Backup Data: “It sounds so obvious but most companies fail to keep 100 percent of their important data backed up 100 percent of the time — there are often gaps in what’s being backed up which are only discovered when it’s too late. The consequences of lost data can put a company out of business on the spot, and data retrieval is frighteningly expensive.”

7. Spam, Viruses, and Spyware: “Eighty percent of all Computer Troubleshooters’ service calls worldwide are from people with problems directly linked to these issues. You should consider good virus protection, spam filters, and anti-spyware programs as mandatory if you want a trouble-free computer.”

According to Reaves, with a small amount of common sense, weekly maintenance (much of which we can set our computers to do themselves), and some small financial outlays, we can have many more trouble-free workdays and spend far less on the IT repair man. This will allow us more uptime to complete our work and give us the chance to explore the myriad other technology opportunities that can help us improve our businesses, and our lives.

Chip Reaves is the national director of Computer Troubleshooters. To help pay for his studies in computer science at Georgia Tech, Reaves began fixing computers for local businesses in the late 1980s. The part-time work quickly became a full-time business, with Reaves establishing Chiptech in 1992. Reaves was surfing the web when he discovered Australia-based Computer Troubleshooters in 1998, and by 1999 he had negotiated the rights to operate CTS in the U.S., a move than has lead to over 230 CTS locations in North America today.

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.
