Page 5: Application And Sizing
APPLICATION AND SIZING In the application and sizing of room air conditioners for cooling, it is most important to give full consideration to all factors which may contribute to the heat loss or gain of the space to be conditioned. It is therefore necessary to make a survey of the space to be conditioned and calculate the load requirements before a selection of the size of the equipment needed can be made. -
Page 6: Instructions For Using Cooling Load Estimate Form
INSTRUCTIONS FOR USING COOLING LOAD ESTIMATE FORM FOR ROOM AIR CONDITIONERS (AHAM PUB. NO. RAC-1) This cooling load estimate form is suitable for estimating the cooling load for comfort air conditioning installations which do not require specific conditions of inside temperature and humidity. The form is based on an outside design temperature of 95°F dry bulb and 75°F wet bulb. -
