Most UK homes need some form of air conditioning these days during the summer months. Central air conditioning is the type most homeowners choose, but portable and ductless air conditioning are also popular options. In hot, dry areas, evaporative air conditioners or swamp coolers are used. Not only do evaporative air conditioners cool the home, but they also humidify the air.
The Typical Central Air Conditioner
Central air conditioners are sometimes built into new homes during construction. They comprise an evaporator coil (situated in the furnace), a condenser unit (placed on a concrete slab or blocks outside the home), and the ductwork (the air distribution system).
But some residences do not need all this horsepower. There is no sense in investing in a large system in an area that only experiences a short, mild summer. There are some excellent alternatives if you are in this situation.
Window Air Conditioner Units
Window-mounted units are not easily portable, but they do a great job of cooling a single room or living area. When do they come in handy? One example is for a small flat. It is impossible and impractical to install a central unit in this case.
Another case is if you are refurbishing and adding a room. Whether hiring professional builders or doing it as a DIY project, the extra space may overwork the central system. Installing a window unit will keep the thermostat happy.
Portable Air Conditioning Units
Portable air conditioning units provide great value for money. They have the advantage of being easily moved from one room to the other. They are also environmentally friendly as minimum energy is used to implement a reasonable level of comfort.
These “windowless air conditioners” are also handy for areas where it is impractical to drain the water collected from the air. These units have a pan that fills with water. When the pan is close to full, a sensor shuts the aircon down to avoid spillage.
When to Use Evaporative Air Conditioners
Evaporative air conditioners are not the most popular choice in the UK as they are more suited to hot dry climates. If you live in such a climate, the one thing you do not want to do is remove more moisture from the air. In fact, evaporative air conditioners have the opposite effect. They add humidity to the air.
How do Evaporative Air Conditioners Work?
These units are quite simple. They are basically a box with blanket pads, often of a cellulose material, hanging inside. A water pump controls the water content in the pads. As a fan blows warmer air through the pads, the water evaporates.
The evaporation cools the air, up to about 20 degrees. It is pushed into the room by the fan. In this manner, a home is cooled and humidified.
What to Look for in a New Aircon Unit
Look for a guarantee and the availability of warranty and spare part suppliers. Many overlook this fact when buying new machinery. Although the home’s square footage determines the air conditioner’s capacity, the key is the unit’s energy efficiency. For central systems, look for the SEER rating (Seasonal Energy Efficiency Rating). Window units use the EER rating (Energy Efficiency Rating).
Most units range between a rating of 13 to 16, with 16 being more efficient. This is a good indication that a new system will help keep your utility bills down.1 comment
