With a rise in the temperature in the country, Central Public Works Department (CPWD) has issued a set of guidelines compiled by the Indian Society of Heating Refrigerating and Air Conditioner Engineers (ISHRAE) advising people about ideal temperature of an air-conditioner during the lockdown.
There has been an increase in the usage of air conditioners and desert coolers as the public has been spending more time at home under the lockdown in the bustling heat.
Due to this, there have been several concerns over the use of ACs and coolers over what temperature should we use the AC at this point of time.
As per the 18-page guideline, the temperature of the home-run AC should be between 24-30 degrees Celcius and the humidity should be between 40-70 per cent.
"Recirculation of cool air by room air conditioners must be accompanied by outdoor air intake through slightly open windows and exhaust by natural exfiltration," the advisory said.
“Too much humidity leads to higher levels of dust mites and fungi, two of the worst culprits for indoor allergy sufferers. Mold and fungi are known to exacerbate respiratory conditions such as asthma,” it added.
The centre also advised people to keep rooms ventilated when ACs are not in use, and to keep the windows partly kept open while using electric fans.
For commercial, industrial facilities, the government has suggested ventilation with outdoor air. “The mechanical exhaust air shall be 70-80 percent of the fresh air quantity to maintain necessary positive pressure in the space,” the advisory read.
