At Angiotech, he installed the APR-E7 control on the lead 10-ton circuit of a 40-ton air conditioning system to extend runtime and minimize cycling. The device provided that lead circuit with the ability to modulate 70% in response to the temperature of the discharge air.
Reichenbach believed that setting up the system to hold a precise 55°F discharge air temperature would provide the most stable comfort level.
Humidity levels within the space were held at 45% to 50% all summer long within an office environment,” he said.
The customer was very pleased and expressed that the temperature setpoint was raised in most of the office zones as a result of the people within the space feeling more comfortable.
Most people usually lower the thermostat to feel cooler when the space has a humidity problem.”
