Description

The Psychrometric Test Chamber’s primary purpose is to evaluate the performance of split type central air conditioners and heat pumps in the cooling capacity range of 12,000 to 70,000 Btu/h (1 to 5 ½ rated tons). It consists of side-by-side indoor and outdoor chambers with temperature, humidity and air flow controlled independently. The Test Chamber is designed to maintain a single set of operating conditions and is able to maintain conditions within the following dry bulb and web bulb temperature ranges:  indoor = 45°F to 100°F DB; 43°F to 85°F WB; outdoor = 10°F to 120°F DB; 35°F to 90.5°F WB. The Balanced Ambient Calorimeter Test Chamber's primary purpose is to evaluate the performance of room air conditioners (split, window, or wall-type), packaged terminal air conditioners, and packaged terminal heat pumps in the cooling capacity range of 6,000 to 42,000 Btu/h (½ to 3 ½ rated tons). It consists of side-by-side indoor and outdoor chambers with temperature, humidity and air flow controlled independently. Both the indoor room and the outdoor room are surrounded by an annular space which independently maintains the same temperature and humidity as the rooms it surrounds. The Test Chamber is designed to maintain a single set of operating conditions and is able to maintain conditions within the following dry bulb and web bulb temperature ranges: indoor = 45°F to 100°F DB; 43°F to 79°F WB; outdoor = 10°F to 120°F DB; 40°F to 81°F WB.
