ABSTRACT:
A portable in situ psychrometric test apparatus and method for determining, without the use of standard environmental test rooms, the capacity that an air conditioner would exhibit when operated under predetermined standard environmental test conditions. Mutually isolated air flow chambers are detachably mounted to the air intake and air discharge openings of the conditioner. Samples of air flowing through the chambers under normal operation of the conditioner are withdrawn and wet bulb/dry bulb measurements taken at the end of a predetermined operating period. Air velocity through the chambers and condenser environmental air dry bulb temperature are also measured. These measurements give in situ operating capacity which is then converted, using predetermined empirically derived correction factors, to operating capacity under standard environmental conditions.
