Residential Air Conditioning
Real cost of fresh air
NUMEROUS STUDIES HAVE shown that increased outdoor venti- lation rates improve our health and productivity while reducing the transmission of germs such as airborne virus and bacteria.
One study concluded that doubling the ventilation rates in buildings has the same effect as the flu vaccination. Every time we double the outdoor ventilation rate, we reduce the concentration and therefore the transmission rate of all indoor contaminants by 40 to 50 per cent.
But the cost of introducing fresh air has usually meant that we have designed HVAC systems with the minimum outdoor air to comply with the standards.
However, the answer lies in energy recovery.
If the mandatory 10 litres/sec per person of fresh air costs $30.00 per annum, doubling this will consequently become $60.00 per person. But if energy recovery was installed, it is possible to introduce 20 litres/sec per person for a cost of $18.00 per annum.

Post-pandemic purification plans
WITH THE COVID-19 pandemic in 2020, de- mand for air purifiers has skyrocketed around the world as one of the preventive measures against infectious diseases.
Daikin, one of the leading Japanese air purifier manufacturers, also increased the cumulative number of overseas air purifier shipments dur- ing the period spanning April to October, 2020, to 3.7 times that of the same period in 2019.
“DAIKIN BEGAN PRODUCING AIR PURIFIERS AT ITS MALAYSIAN PLANT AT THE END OF 2020”
To meet this surge in demand, Daikin began producing air purifiers at its Malaysian plant at the end of 2020.
The company started with an annual produc- tion system of 150,000 units with plans to ex- pand later this year.
A new report by the Business Research Com- pany found the global air purifier market size is
expected to grow at a compound annual growth rate of 10.8 per cent to nearly $2.35 bil- lion by 2023.
The market is expected to reach nearly $2.88 billion by 2025 and $4.82 billion by 2030. North America accounts for the largest share in the global air purifiers market, the report said.
One product that has generated a lot of inter- est as a result of the pandemic is
‘wearable’ personal air purifiers.
sonal air purifiers are versatile, easy to maintain and are relatively quiet.” Most of the personal air purifiers in use today use ionic air purification technology.
They are ideal for small spaces such as ve- hicles with stale or smelly air, and other public spaces where the quality of air can- not be guaranteed.
The report said increasing res- piratory health awareness and the omnipresence of pollutants and viruses in the air, has led to consumers becoming more cau- tious about the type of atmos- phere they breathe.
“These small machines can ef- fectively eliminate common con- taminants like dust, smoke, odours, volatile organic com- pounds, and allergens within one’s personal breathing space,” the report said.
“They are lightweight and can be carried around easily using a neck strap, a clip, or a band. Per-
Consumers have become cautious about the air they breathe.
