In accordance to the standards of the building air supply systems in Thailand, it is recommended that there should be no less than 2 ACH in the fresh air system. (2 ACH will not affect the operation or heat load of the air conditioner that was calculated in the first place, which normally calculates the cooling load within the normal building in Thailand. Without allowance for exhausting, it is calculated at 750-850 BTU per square meter.)

There is no specific standard for how many ACHs are required to recirculate indoor air in the event of the Covid-19 outbreak.

The customer agreed with Camfil’s proposal to base the design on the MOH’s guidelines for field hospitals.
