Low Flow Diffusers & Changing Energy Codes

Titus’s energy-saving TJD diffuser also satisfies comfort, functionality and aesthetics needs

 

Ventilation (outside) air has traditionally been delivered through the primary cooling system. Utilizing one set of ducts and air outlets to provide both comfort conditioning and ventilation. The state of Washington’s latest energy code revisions now specify Dedicated Outdoor Air Systems (DOAS) with parallel air distribution to the space for the majority of compliant systems. What does this mean for the construction community and building occupants? In conventional systems the ventilation air is a part of the overall supply air flow. The additional air provided adequate velocity to evenly distribute and mix the outside air over the entire space. Airflow rates of DOAS alone do not provide adequate velocity at the air outlets to distribute the outside air. The result is excessive vertical projection (dumping) from the air outlets.

 

The TJD (patent pending) distribution provides high mixing at low airflows to provide superior coverage and throw. While most air outlets typically work at 100 CFM, TJD performs at 20 to 50 CFM and throws air to 9 feet at 50 feet per minute. The high mixing increases the mass of the discharge isovel and its corresponding throw, providing both uniform temperatures throughout, while delivering outside air equally throughout the occupied space. This equates to ADPI of 97 for an airflow of 26 CFM in a 120 SQFT Room. The ADPI increase to 100 at 47 CFM. The TJD is capable of distributing outside air effectively down to as low as 0.06 CFM/SQFT Minimum Ventilation Rate per ASHRAE 62.1-2016.

That means engineers can both meet the latest codes and reduce air volume dependence, and building owners can achieve noticeable energy and operations savings while ensuring occupant comfort.

TJD is best suited in areas where low airflow codes are applicable such as smaller spaces with low equipment and external loads. TJD incorporates Titus’s popular architectural plaque diffuser, giving it a polished look. Mark Costello, Titus Product Manager stated "Forward-thinking customers can get ahead by using a solution specifically designed to meet industry codes and achieve functional, aesthetic and comfort needs."

TJD’s release comes on the heels of Titus’s 2017 AHR Innovation Award win in the Ventilation category for its Helios diffuser, the industry’s first ambient light-powered digital diffuser.

Learn At Your Own Pace - Titus eLearning Website

We live in a much different time now compared to when we were kids. Growing up, schools were the primary resource for learning and for the vast majority of us teachers only taught inside the classroom. Computers were big and bulky and never left the school either. Textbooks had bookcovers to protect them from the weather and sometimes your backpack weighed too much to carry home.

Fast forward to present day and learning has greatly changed. There are an abundance of options to conventional learning methods of the past. Many schools now rely exclusively on tablets to serve as their books of today. The creation of the internet allows information to be shared in an instance. Computers, laptops, tablets, and even smartphones are now portable and have the ability to stream and store video content. We are a more mobile and versatile society today - our schedules are more fluid than the ones our parents worked in the past. Our options to learning have to be just as adaptable as time is a precious commodity now and we utilize every second more efficiently.

The Titus eLearning Website - http://www.titus-elearning.com/ - allows any industry professional to learn at their own pace while earning PDH credits along the way. (Please note that requirements for credits may vary by state). The courses are prerecorded and the video segments range from 3-7 minutes in length. All you need to do to begin is go through the registration process. Once completed, simply select and watch a webinar for one the subject areas already loaded on the site and you are on your way to learning more about HVAC. Additionally, if you require additional time to watch because something comes up, stop watching and when you come back the video begins exactly where you left off.

Our Course Catalog has a wide array of subject matter to choose from too. Have an interest in Healthcare/Critical Environments or Terminal Units, we’ve got the course for you. Do you need a refresher in Basic HVAC Design or Underfloor, those courses are loaded as well. New classes are always in development and we hope to double the course selection by the end of 2017 with fresh new content.

One of the best features about the eLearning Website is that it applies to all industry professionals. It was designed as an enhanced learning tool for all to use and benefit from - length of service or experience in the field isn’t a factor. If you have 0-5 years of experience or 35-50 years of experience, the website has information designed to teach and inform as if you were sitting in a consulting engineering seminar session. To check for understanding, there are 10 question quizzes to assist in reinforcing what was presented. During the quiz, if an incorrect response is noted the system will display the video slide in which the correct reply was discussed and request the user to retake the quiz.   

We live in a 24/7 world and the eLearning Website is the 24/7 solution for HVAC training exactly how you need it - On Your Own Terms! Learn what you need, when you need and let us partner with you through the process. We hope you are as exited about it as we were to launch it.
