WHAT IS THE DIFFERENCE BETWEEN A CENTRAL AIR-CONDITIONING SYSTEM AND AN AIR COOLER?
A central air-conditioning system is a ‘closed’ system. The air flows through a filter and is circulated through a refrigeration cycle where the heat is removed. The air is then sent into the living space through the outlet registers. A clean filter and tightly closed exterior doors and windows help this type of system work most efficiently. In contrast an Air Cooler is an ‘open’ system. Air Cooler evaporates the water from cooling pad installed in the coolers to cool the circulating air. This cooling principle is similar to the perspiration system of our skin, which our body uses to keep us cool during summer.
WHAT IS THE RELEVANCE OF RPM IN AN AIR COOLER?
rpm (rotations per minute of fan) offers better cooling efficiency but is associated with higher air cutting sound / noise. It is therefore better to have bigger fan size and lesser rpm for a sound free operation of the cooler. All the present coolers in the market use electronic speed control switches against the earlier 3 step speed control regulators and are able to offer
multiple rpm adjustments and better speed/sound control.
DO AIR COOLERS ACTUALLY SAVE ENERGY?
An Air Cooler uses 70% less power than Air Conditioner. The annual energy savings make Air Cooler a cost effective alternative to Air Conditioner
WHAT IS RELIEF AIR AND WHAT IS THE MEANING OF UNRESTRICTED AIR RELIEF AREA?
As an Air Cooler draws fresh outside air through the cooler into the home, hot stale inside air is exhausted out of the home. This is referred to as relief air. Generally speaking, a good relief design (air relief area) exhausts
slightly more air out of the home than your cooler supplies.
HOW MANY WINDOWS AND DOORS MUST I LEAVE OPEN?
It’s all based on the unrestricted exhaust air openings your home requires. For every 00 square feet cooling area, allow 2 square feet of unrestricted air relief through windows or doors.
HOW COOLED AIR CAN BE DIRECTED INTO VARIOUS ROOMS?
Direct the air exhaust / air relief from primary room by opening windows or doors in second room. The second room should have an unrestricted / relief area on the
opposite wall for exhaust air (2 square feet for every 100 square feet).
