Summary

Russ King joins us to discuss simplifying duct design for residential contractors. We focus on using 3D software for duct modeling.

While computers are great tools for duct design, you must be careful with them. Computer technology doesn't correct your mistakes; it allows you to make mistakes more quickly. Russ made 3D software specifically for duct modeling, and its goal is to help technicians/contractors with duct designs and equipment sizing. The software is good for quick duct design, can determine flex duct design, and is ideal for broad usage in residential HVAC.

Russ has noticed that existing energy modeling and load calculation software ask for extremely specific inputs, which can confuse technicians. He was frustrated with the process and wanted to make software that could help technicians solve the problems that mattered in a way that made sense. With the help of his son, Russ came up with Kwik Model (of Coded Energy). They developed software that allows users to design ducts and adjust parameters easily. The goal is for Coded Energy to be a simple, straightforward duct design software that addresses the hardest duct design issue: making the ducts fit.

Coded Energy is written in Unity, which is used for video games and architecture/automotive design. The user essentially imports a floor plan, scales it, places boxes, and stretches the boxes to meet the design conditions. Once the user has built the house, the software can calculate the surface area automatically. Then, the user can use EnergyGauge for load calculations and equipment selection. The user can then draw ducts and have the software size the ducts for them.

Russ and Bryan also discuss:

Equipment selection for latent removal capacity
Oversizing issues
Designing ducts for building plans
Comfort diagnostics
2D vs 3D modeling
Getting feedback in the field post-design

0:00.0	This episode of the HVAC School Podcast is made possible by our great sponsors and I say that all the time but it's really true
0:10.4	Our first sponsors carrier and carrier. We're excited about the new
0:14.0	line of infinity equipment that carrier just came out with that you can actually do the
0:18.4	commissioning using a app on your phone and Bluetooth. I'm going to actually be trying it out tomorrow and I will
0:24.9	let you know how that goes to be putting up some videos on that we're excited
0:27.8	about the new product line very high efficiency also very high EER and great de-humidification, which is always one of the main things I look for in Florida.
0:37.0	Find out more carrier.com.
0:39.0	Also Blue On and Blue on energy.com. Blue on is the company that's focused on helping technicians do retrofits better.
0:47.0	So the training side, product manuals, all that.
0:50.0	Start by downloading the free Blue Onon app just go on your iPhone or on your
0:55.5	Android device download the blue-on app take the short training and learn all there
0:59.8	is to know about retrofitting and about high-glide refrigerants and everything you need to know about retrofitting and about high glide refrigerants and everything you need to know and
1:05.0	then you will be prepared to start to retrofit.
1:07.8	Blue Won is your partner and all of that.
1:09.3	Sure, they make a great refrigerant in TDX20, but they're excited to help technicians do retrofits better and to provide solutions across the board.
1:19.0	So find out more, Blue On Energy.com.
1:22.0	Also, Navac and Navac Global.com.
1:24.0	Navac makes incredible vacuum pumps.
1:26.0	They make vacuum pumps that are actually battery powered.
1:28.0	If you haven't seen their two and four CFM battery powered vacuum pumps all the way up to their really high capacity 12
1:35.5	CFM pumps that are great for commercial and industrial environments. They have a
1:38.8	full line. They also have several different recovery machines.
