PTT GAS
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.)
RECIRCULATED AIR:
There is no specific standard for how many ACHs are required to recirculate indoor air in the event of the Covid-19 outbreak. Therefore, Camfil Thailand chose to follow Thailand Ministry of Health’s guidelines (MOH) of the minimum 6 ACH for field hospitals to apply to this project. The customer agreed with Camfil’s proposal to base the design on the MOH’s guidelines for field hospitals.
