Screwfix 2

 I think professional aircon installers are going to have to undergo some form of reality Check, sooner or later, And as is often the case, sooner should be better than later. Until very recently, air conditioing was a luxury that people could never consider for their homes. The market was for quality commercial products, installed in a tailored manner by quality installers. But there is a whole new market opening up, and operates with different rules and with different value criteria. Installers who adopt the “it’s got to be a top-spec solution or it’s no solution at all” attitude will find themselves missing out on a very valuable and legitimate market to enter.  Let’s take an honest look at the product fitted. It’s not an inverter model, but it makes it cheaper, and the capital cost verses running cost equation is something people will have to decide for themselves, as is the noise level they can tolerate at on 37 decibels .  Overall I think installers are being too harshly dismissive.On a proffesional level they have virtualy no appeal or use.They are not made for that market.As a cheap domestic DIY system you could do worse, (but not much!)Not sure, I think you could probably do a lot worse. But more to the point, how much better could you do, and how much would that improvement cost? How long would it take to recoup the extra cost? If you go to Savile Row and have a suit made for £5K it will fit you perfectly and last a lifetime, but that doesn’t mean that millions of people aren’t happy enough with an off-the-peg one at a twentieth of that price from Marks and Spencer, nor does it mean that Marks and Spencer suits are cheap rubbish, far from it/ Britains manufacturing and service industry has a legacy of corpses of companies who dismissed low-cost, “upstart” products as being of little appeal or use. 

Think on.

Air Con Maintenance

Friday, March 7th, 2008

ROUTINE MAINTENANCE
Neglecting maintenance ensures will steady decline in the air conditioning performance while energy use steadily increases. Keeping the system properly maintained will lower energy and repair costs, prevent breakdowns and prolong the life of your unit. Some maintenance jobs should be left to the professionals, but there is much that you, as a homeowner, can do to prolong the life of your units, keeping it running at peak efficiency.

 FILTERS
The most important maintenance task that will ensure the efficiency of your unit is to replace or clean its filters. Clogged, dirty filters block airflow and reduce a system’s efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Filters are located somewhere along the return duct’s length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself.
Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house. If you use a disposable type filter, it’s always wise to keep several spares inside the house. 

BTU British Thermal Unit

Friday, March 7th, 2008

BTU (British Thermal Unit) - The standard of measurement used for measuring the amount of heat required to raise the temperature of one pound of water by one degree (Fahrenheit).

The British thermal unit (BTU or Btu) is a unit of energy used in the United States, particularly in the power, steam generation, and heating and air conditioning industries. Although it is still used ‘unofficially’ in metric English-speaking countries (such as Canada, the United Kingdom, and sometimes in New Zealand), it is increasingly an outmoded and outdated unit of measure. Elsewhere (and always in scientific use) the BTU has been replaced by the SI unit of energy, the joule (J).

In North America, the term “BTU” is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU per hour (BTU/h) is understood, though this is often confusingly abbreviated to just “BTU”. In the United Kingdom and other parts of the world it is written BTU.

The unit MBTU was defined as one thousand BTU presumably from the Roman numeral system where “M” stands for one thousand (1,000). This is easily confused with the SI Mega (M) prefix, which adds a factor of one million (1,000,000). To avoid confusion many companies and engineers use MMBTU to represent one million BTU. Alternatively a therm is used representing 100,000 or 105 BTU, and a quad as 1015 BTU.
