HVAC&R Equipment Environmental Chambers

Large "Truck" Chamber The conditioning equipment can remove up to 35 kW (120 000 Btu/h) of heat at a dry-bulb temperature of 35°C (95°F) and 50 % relative humidity. Full range dry-bulb temperature control of ± 1°C (2°F) with relative humidity control better than ± 2 % is possible. At ARI heating and cooling conditions, control of dry-bulb and dewpoint temperatures are better than 0.1 °C (0.2 °F).   Air-Conditioner and Heat Pump Test Chambers The outdoor chamber has a temperature range capability from -18°C (0 °F) to 60 °C (140 °F) with relative humidity controlled within ± 2%. At ARI heating and cooling conditions, control of dry-bulb and dewpoint temperatures are better than 0.1°C (0.2°F). Units with cooling capacities up to 35 kW (120 000 Btu/h) may be tested.   Small Appliance and Refrigerator Chamber Dry-bulb temperature may be controlled from -18°C (0°F) to 65°C (150°F) with relative humidity controlled within ± 2% of setpoint. At ARI heating and cooling conditions, control of dry-bulb and dewpoint temperatures are better than 0.1°C (0.2°F). Maximum heat removal from this chamber is 11.7 kW (40 000 Btu/h).
