5:40 and 14:51 - You’ll also notice here, guys, that the fins on all these coils are extremely thin. Notice the fins bend flat every time he punches his finger or fist into the coil. No heat will be exchanged at that exact point until they’re straightened back out!
Thanks again David, I have really learned a great deal from your videos and look forward to the day of your next training video. Keep up the great work
Looks like there was also some face and bypass dampers by the DX coils. I've worked on plenty of Munters units, never a 4 seasons. Cool video and explanation. A DOAS unit is also designed to keep a neutral temp not designed for comfort cooling/ heating
Good eye Jason, you nailed it these are not designed for comfort cooling/heating designed to maintain a target temp and humidity while supplying make-up air like you said. Thanks for spelling that out a little clearer than I did in the video, appreciate it !!
@David Harty how are those face and bypass dampers set up. Im assuming its taking outdoor ambient and enthaply. If conditions are correct, open the bypass/ snd or modulate and cool with ODA or keep discharge air temp at set point.
@@jasonjohnsonHVAC Target runs them with as much outdoor air as they can based on temp and humidity like you said during occupied hours year round They’re using them for dehumidified make air in the summer and heated / dehumidified make up air in the winter, for the grocery side of the store Bypass is only closed in night setback mode / unoccupied

Nice job. Thanks so much. Give us more info.......
Great video! Thanks for sharing!
Thanks for watching!
Great video thanks for sharing
You bet, Thanks for watching
Now I know who is bending the fins on the coils all the time.
I thought he was gonna poke a hole in it!!
Great great info
Glad it was helpful!, I was actually eating a bowl of rocky road ice cream when i was posting it last night :)
GREAT VIDEO DAVE love the detail
Thanks Chris, appreciate that
👍👍👍
Thank You !!
5:53 did that bother anyone else?😂 thought he was going to write his initials haha.
That was combed out after finishing the video, forgot how soft those reheat coils fins were while concentrating on the explanation of the video
Looks like a lot waste of energy
Good instructional video, treat your customers equipment with more care. Jeez…
That was combed out as soon as we finished the video
