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
