Damn bro, that company or one of their competitors needs to hire you. You just gave away a fortune in research and development savings for them. But great experiment, excellent details and very smart design
Thanks for the video. Was looking for a personal cooling solution for people working on a food truck. What with a hot grill, fryer and the exhaust venting system, Rooftop air conditioners can't compete. Just physics. I have been looking at vest-type systems for personal temperature maintenance, like evaporative vests, Ice inserts, and PCM inserts, and a circulatory system like what you tested. This looks like it answered my questions!.
Howdy, had you considered a refrigerated cooler versus the issues with the ice? There are some out there that operate on 12V or even batteries that might keep the water cool enough consistently without the melting ice issues.
@@strings1955 I have another video where I tested a chiller by the same company. It works really well. They also offer the battery operated back pack systems. I haven’t tried the backpack system though.
Very good research. Thanks for all the effort. I am looking to buy it for motorcycle use. How hard are the tubes that run through the vest. Are they soft enough not to cause any serious injury to the ribs/spine in case of a crash?
The timer is hooked up inline with the power wires, prior to the power supply for the pump. The timer has 3 connections. There is a ground, 12v in and 12v out. The supply +12V positive connects to the +12V input of the timer. The +12V out on the timer connects to the +12V wire of the pump power supply. The ground from your input connects to the ground of the timer and the ground for the pump power supply.

Thanks for making this video! Great work! I'm a utility worker in the south. I decided to get the univest. I'm hoping it'll help through the summer.

I would have put a cup of salt in the water to lower the temp

Please provide us a "long term" dependability report . . Is the system still working well. Any issues with the pump or battery ?
great job! stay frosty!
get the KOOLGEL ice extender, it turns the ice to gel, get the powder form make your own ice blocks
I'll have to check that stuff out!

The tubes feel like thin silicone tubing. They are pretty flexible.
@@HeBeGB501Thank you!
How did you connect the variable device that alternates turning the pump on/off?
Fantastic video!

Too complicated 🫣
