At AHR, Ruskin introduced a truly novel product, the AIRFLOW-IQ, which combines the features of the company’s TDP05K air flow and temperature measuring probes, with its CD50 control damper and the VAFB24-BAC RAMS Air Measurement BACnet actuator. The factory-assembled and calibrated unit provide effective setpoint airflow control from 0 to 5,000 FPM (0 to 25 m/s) using analog or BACnet interface. The ultra low-leak, class 1A-rated CD50 damper helps satisfy the requirements for minimum outside air as required by ASHRAE 62.1, 90.1 and 189.1, California Title 24, the Int’l Mechanical Code and the Int’l. Energy Conservation Code. According to the manufacturer, one of the ma

With four-way vane control, occupants can select two-, three- or four-way airflow patterns, and each vane can also be adjusted individually. The optional 3D i-see Sensor, which calculates room occupancy rate, adjusts conditioning accordingly with direct or indirect airflow settings, offering dozens of different comfort combinations and improved energy savings, with a SEER rating over 19.8 and even temperature distribution.Judge’s Comment: “Comfort made easy.”

The LG Multi V 5 with LGRED° heating technology provides savings and flexibility by offering more capacity in a single compact chassis.
