Mitsubishi Electric recently introduced its CITY MULTI® ceiling cassette indoor unit, featuring the new 3D i-see Sensor™. The 3D i-see Sensor is a small component mounted to the exterior panel of the ceiling cassette. The sensor continuously analyzes the thermal profile of a room, identifying cool and warm spots. To achieve an accurate thermal profile, it performs hundreds of circular scans, with multiple points per scan, continuously monitoring.
Cooking over a wood flame is hardly a novel concept, but as a popular trend in restaurants, it causes headaches and occasionally much worse from a life safety perspective. Survey a range of incidents and get reminded why creosote is a key enemy in this environment. Then finish with a look at what manufacturers, designers, and owners are (or should be) doing to win a new duel with an old fuel.
Sometimes it does pay to sweat the small stuff. Data availability might vary depending simply on where you’re accessing it. Not only selection but placement of your sensors and transmitters can influence their effectiveness and response time. Bearing down on such details on the BMS side can yield long-term results for your cooling goals.
Clarify the difference between pressure dependent and pressure independent systems, and then make a deep dive into this TAB process. There’s a lot of science involved, but in the end, steering and tweaking the process may seem more like an art.
Good IAQ management has become paramount in the construction industry, as study after study shows that employee productivity and health are directly related to the quality of air being delivered inside the workplace environment.
MEMSIC Inc. has created its MEMS based pressure sensor designed for VAV damper control as well as HVC applications such as room pressure monitoring, fume hood controls, furnace press switches, heat recovery systems, burner control, fan control, filter monitoring, and many others.
Distech Controls has introduced the EC-Smart-Air, the latest addition to its Allure™ communicating sensor series. Designed for projects that require precise environmental sensing, the EC-Smart-Air is a three-in-one sensor, combining temperature, humidity, and CO2. Distech Controls says its latest offering allows for time and cost savings with a single device to be mounted, wired, and commissioned.
Sensaphone® will introduce its Sentinel™ PRO remote monitoring system, an enhanced version of the Sentinel cloud-based system that provides 24/7 remote monitoring of unattended HVAC units, freezers, refrigerators, boilers, and chillers. The Sentinel PRO system supports the Modbus communications protocol and includes a second relay output — capabilities required to monitor and control complex networks.
Engineered Systems magazine’s May 2020 issue examines the revitalization of air-cooled chillers in data center facilities, the viability (or lack thereof) of duct systems, the impact the coronavirus is having on the built environment, and much more.
