cool project part five

  • Added:  2 months ago
  • Final test of the new Pepino swamp cooler. For this test the pump cycle was set to 29 seconds on / 100 seconds off. Total elapsed time was 5 1/2 minutes which is a little too long to stare at so I edited out a little. Still pretty swift cooling considering. Their was no edit from the beginning to the initial drop of the temperature. It happened fast because I had already run some water through the pad. A twenty degree drop is about the best you can do with a swamp cooler although I can max it out at about 25° on days when the humidity is below 10%. When this Pepino gets installed for the new owner, a second cooler will be used instead of my now famous bucket. Here is a basic parts list.

    95 to 79 deg hmmmmm i think you need to redue your math LOL 16 deg not 20

      I agree its not for everyone who maybe out on the road or land, you have survived out in the middle of hell for awhile, I applaud you for your survival skills, we need next gen solar panels

      I built the first Pepino before I had enough solar to run an AC...and because if its small size, it only brings the humidity up to a comfortable level...from 15% to about 50%. And it works quite well cooling down the hut after dark when running an AC would be a problem.

      no kidding silly was intentional, anyways since you have decent solar power and or battery storage no need to that type of system AND who want to add all that humidity into a house??

      I tell you what....watch the video very carefully and tell me again how I need to "redue" my math. Hmmmmm i think you need to redue your spelling LOL redo not redue

    Wish these things worked in East Texas (90% humidity). Our heat will make it tough to ever go all the way off the grid out here. Great series though. Amazing what can be DIY'd. My wife and I love this channel.

      I will have to talk to my wife about that curling iron! Wish me luck on that. I reckon when the time comes we would be looking at something under 450 sq ft. And darn good insulation. Hope those bunnies found some water today also.

      All depends on what size house you are trying to keep cool. It only takes about 1,000 watts of solar and an appropriately sized battery bank to to run a 10,000 BTU air conditioner. Just don't run your microwave, toaster oven, and curling iron at the same time...

    JW, your fabrication skills always amaze me.
    Very nice work.

    Nice! Amazing how fast those temperatures melted off at the point of measure. How long was it before the ambient temp in the enclosed room changed? I imagine the room felt the win pretty fast.

      During the hottest part of the summer out here, the humidity rarely gets above 10%.

      Please tell me that its a dry heat. I grew up in Sacramento. 120 degree summers. But a dry heat. In mid-adulthood I lived in New England 20+ years, and 100% humidity at 90 degrees is terrible. Swamp coolers don't do well in high humidity. So we just lived with the heat... In high humidity it feels like you are sleeping on a warm damp sponge.

      A cool night for sleeping is waaaay up there on the priorities list.

      It is actually a very slow process - and it depends on the size of the space and the amount of insulation. Pepino can only keep up if the outside temperature is below 100°...after that it is a loosing battle. The nice thing is it helps to cool down my hut after the sun goes down and the outside temperature starts to drop allowing for comfortable sleeping temperature.
