Choosing an air conditioning system
When choosing an air conditioning system, most people focus on how effective it will be in cooling a space as opposed to which filter pads to use how it actually does the job. What gets lost in the shuffle is the indoor air quality (IAQ), which can become an issue if the wrong type of system is put in place. China is a perfect example of how dangerous IAQ can be, with as many as 3 million children in the country dying for health issues caused by poor air quality indoors and out. An Australian company has come up with an invention that they believe will address the air quality problem, as well as the CO2 issues caused by air conditioning systems.
Cost and efficiency from fresh air
Most air conditioners today use evaporated or refrigerated air to cool the spaces they serve. Evaporative units used air conditioning filters that deliver a healthy moisture content designed to effectively cool the room. The spent air is then usually sent back outside via an open window. Gas is used to cool the air in refrigerated units, and it creates indoor air that is very dry, and which can cause coughs and skin irritation. The system that employs evaporative air conditioning filter pads is quickly becoming the more popular of the two because of cost and efficiency from fresh air.
There are still a couple of issues to be addressed.
Firstly where to find the information on this system. What preventative maintenance is involved and an evaporative cooling technician to perform this maintenance. Once purchased how available are the spare parts when required.
The problem is that air is often recycled, which means that the less than perfect air that gets drawn in from outside via a number of different methods get constantly send into the indoor space. The air conditioning filters designed to take out the impurities can only do so much, and the recycled air remains polluted after recycling, all of which leads to pretty awful indoor air quality. The systems that deliver the cool air have evolved over time, but the way in which they deliver the air has essentially remained the same. The air delivered should be 100% clean, and CO2 levels at 300-400 parts per million or less, but very few systems can come close to delivering that.
Cool air should be delivered low, and warm air extracted at ceiling height
The biggest issue is the way that cooled air is delivered, which is usually via window, ceiling, or wall mounted units. This makes it virtually impossible for quality air to be consistently sent into the space. SISACS have created a delivery system that delivers air at floor level, which is perfect since warm air rests on top of cool. For best delivery and extraction results, cool air should be delivered low, and warm air extracted at ceiling height, while the reverse is true for warm air delivery. This also allows for clean air to be constantly drawn into the space, killing all airborne germs in the process.
Finally, the new eco-friendly system also addresses the CO2 buildup issue that every air conditioning system has to face. The system essentially scrubs the air to remove as much as 60% of the CO2 buildup, which also helps create a level of indoor air quality that is second to none.
