While heat pumps are the most energy-efficient cooling system for our local climate, many homes in the Valley are equipped withThese units perform best when the outside humidity level isHere is some information to help you get the greatest comfort and efficiency from your evaporative cooler. An evaporative cooler is a box-shaped appliance with one or more porous surfaces that enable air toA fan inside the unit pulls outside air through the sides and into the house. cool air, each porous side is fitted with a pad of water-absorbing material. Water is stored in a pan at the bottom of the cooler and a small pump lifts the water to the top of each side. To effectively cool your home, each pad needs to remain damp, but not soaked. the most evaporation and, therefore, the most cooling. The amount of water the pump moves may need to be adjusted from time to time to properly dampen the pads. Climate control inside a home with an evaporative cooler depends on proper air balance.

humidity, you need to make sure that the same volume of air flows out of your home as is pumped in.size a window air conditioner You can attain balanced air flow by installing ducts in each room or opening windows when theare window ac units safe cooler is in use. green hvac unitsA window should be open just enough to allow air pressure inside a room to slowly and quietly close the door to that room. If the door closes forcefully, there is too little exhaust and the window should be opened wider. However, the window is open too far if the door doesn't move at all. To choose the right size evaporative cooler for your home, you need to determine how many cubic feet of air per minute (CFM) the unit can pump. If you can't locate the CFM number on your evaporative cooler or in the owner's

manual, the following formula will help you calculate it: Example: 1,625 sq. ft. x 8 ft. (ceiling height) = 6,500 CFM/2 Have your cooler serviced twice a year, prior to the cooling season and midwayRegular maintenance will help extend the life and efficiency of the equipment. Before starting up the unit, perform these simple maintenance steps: Evaporative cooler thermostats, available at many hardware stores, automatically turn off the cooler when the air reaches a desired temperature, making operation Most evaporative coolers without thermostats have separate switches for the fanIf your unit lacks a thermostat, allow your pump to run a few minutes before turning on the fan. This saturates the cooler pads. Evaporative coolers and central air conditioners both serve the same important purpose: keeping us cool. But these two systems operate very differently. Understanding the difference can help you get the most out of your system

and minimize wasted energy. Evaporative coolers cool air by filtering it through water, thus lowering itsEvaporative coolers produce humid air because the air absorbs water during the cooling process. These systems work best when a small amount of outside air circulates into the home while the cooler is on. Central air conditioners, on the other hand, work by taking humidity out of the home. These systems produce cold, dry air and work best in an airtight home. Regardless of what type of system you have, make sure it is operating properly. Systems that leak water, make unusual noise, or that don't produce cold air are probably not energy-efficient and can increase your energy bill. The major advantage of an evaporative cooler is that its operating costs are typically half those of a central air conditioner. Valley's monsoon season (between July and August) humidity often rises and, when combined with high temperatures, limits cooler effectiveness.

For that reason, few Valley homeowners rely exclusively on evaporative cooling. Lower original equipment cost than air conditioners Reduced control over temperature in house Air is not cleaned as well as with an air conditioner Need to open windows or vents to outside Damp air can cause doors and wood furniture drawers to swell Requires more maintenance than an air conditioner Air Coolers, Fans and Air Conditioners Air conditioning and fans Air coolers, fans & air conditioners - Argos buying guides Warm weather and high humidity levels can make your home or office hot, stuffy and uncomfortable. Why not consider an air cooler, fan or air conditioning unit to help you stay cool in the day and sleep easier at night? This guide takes you through the different air cooling appliances in our range and explains the benefits and key features you should look for when considering your purchase. Air coolers are portable units which can be easily moved around the house as required.

They work by using water, stored in an internal water tank, to supply a filter that the hot air is drawn through and subsequently cooled before being returned to the room. They perform at their best when the air temperature is hot and the humidity level is low. The humidity level will influence the level the air cooler can cool the room. Typically they will lower the room temperature by 2 to 3 degrees What are the Benefits of air coolers? Air coolers do not require a hose vent so it is not necessary to place them near an external window. Many have castors, making them easy to manoeuvre. Key features to look for Speed Settings - The number of settings on the air cooler, the greater the settings the more control you will have. Tank size - The size of the water tank in litres, which has to be kept filled. The larger the tank the longer the air cooler can run. Timer - Gives you control over the amount of time that the appliance is turned on. Remote control - Many air coolers are supplied with a remote control for ease of use.
