Room Air Conditioners – Energy Saver

News
Room or window air conditioners cool rooms rather than the entire home or business. If they provide cooling only where they're needed, room air conditioners are less expensive to operate than central units, even though their efficiency is generally lower than that of central air conditioners. For ways to save on cooling costs with a room air conditioner, check out our Energy Saver 101 Infographic: Home Cooling. Smaller room air conditioners (i.e., those drawing less than 7.5 amps of electricity) can be plugged into any 15- or 20-amp, 115-volt household circuit that is not shared with any other major appliances. Larger room air conditioners (i.e., those drawing more than 7.5 amps) need their own dedicated 115-volt circuit. The largest models require a dedicated 230-volt circuit.

Split system air conditioners

News
A split system air conditioner is a refrigerative air conditioner that splits its components into two parts: an indoor unit, which contains the evaporator component, and an outdoor unit which houses the compressor and condenser components. With a reverse cycle air conditioner, the condenser (which is responsible for expelling unwanted heat) is also located in the inside unit. The two units are connected by insulated tubes, which are typically piped through a small hole in the wall. Split system air conditioners are fairly quiet and can be easily installed (by a qualified installer), which helps account for their popularity in Australia. They are also convenient to operate, usually via an infra-red remote control. Where to install split system air conditioners It’s hard define a ‘best’ location in a house to…

Not so many years ago, air conditioning was a luxury vouchsafed only to the privileged few; now, though, it's the norm in many offices and public transport systems, so it's a part of our lives whether we want it or not.

Let's take a look at the pros and cons of keeping your cool:   Benefits: Extreme heat has a clear negative impact on the intellect and on physical activity and the use of air conditioning can go some way to rectifying this. It improves comfort levels at work and at leisure. It improves job performance. It can result in increased physical…
