System Sensor says it has fully redesigned its L-Series line of fire and life safety systems. According to the company, the enhanced and expanded L-Series features a lower current draw that is up to 35% more efficient, reducing the number of power supplies needed.
In this section of our post-AHR/ASHRAE coverage, your intrepid editor traverses the carpeted hallways of Las Vegas, taking copious notes at gatherings to discuss two specific standards past, present, and possibly future.
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.
Check out Engineered Systems magazine’s November 2019 issue continues the discussion of condensation on active chilled beams, examines the dynamic cooling solutions required in data center applications, the implications of USP 800 on pharmaceutical comfort, and much more.
