Thermal comfort sensor

Building Systems Division of Yamatake-Honeywell Co., has developed a new TY4700 Comfort Sensor that revolutionizes indoor comfort control. Thermal comfort depends on many factors-the new sensor's output temperature signal is a combination of air temperature, radiant temperature and air velocity. The comfort sensor consists of a sensor unit and a processor unit. The sensor unit has a compact, light but accurate compound sensing element which detects air temperature, radiant temperature and air velocity. The processor unit uses the input data to provide an output signal representing the room's thermal comfort/discomfort factor. Building automation (BA) systems can combine this output with humidity data and stored knowledge of tenant's clothing and physical activity to calculate the ISO7730 standard Predicted Mean Vote (PMV) thermal comfort index, which ensures maximum comfort for tenants and minimum energy expenditure for building operators.<
