    The freon after it has gone through the cold coil then is dumped into the compressor can where it absorbs the heat from the compressor motor, when it is running. When it is off the compressor gets rather warm.
    The issue with the newer cheap dehumidifiers is that the compressor is all sealed up, no ventilation to allow for convective cooling. Unlike a refrigerator, chest freezer, window air conditioner, portable air conditioner, water coolers or central air conditioner where the compressor is out in the open allowing for convective cooling.
    I have a GE brand dehumidifier & I notice the room getting quite warm as it lowers the humidity level. Which is why it was shipped back to Amazon from another customer.

    wow somebody actually describes the process well most people get it completely wrong .I see so many people thinking the compressor puts out cold freon liquid rather than hot gas
    the only thing i would add is the heat from compressor actually makes air warmer coming out then when it went in through the condensing coil getting rid of the compressor heat

    Actually in addition to the compressor getting hot, the air coming out of the dehumidifier is about 10-15°F warmer than ambient temperature due to the release of latent heat. Evaporation absorbs latent heat energy, thus cooling things down. Therefore condensation, which is the opposite and what ends up dripping in the tank, releases it, thereby causing the temperature of a small room to rise significantly when running a dehumidifier.
    The effect on sensible heat energy (temperature) by the release of latent heat energy is about 970 BTU/lb of water collected in the tank. The heat produced by the compressor, and less so the fans is about 3400 BTU/kWh. If a dehumidifier removes 1 lb of water in one hour and pulls 400 W. (That’s 0.4 kWh). 3400 X 0.4. So there’s about 1,360 BTU of sensible heat from the compressor and fans and 970 BTU from latent heat release. In this case 41% of the sensible heat produced is actually from latent heat release.

    Awesom job explaining how a dehumidifier works. Last one we had stopped working, we moved, and I had to repurchase another one to help keep basement humidity low. Since we've had hot days and been running our heat pump, the humidity has jumped to 65'ish%. Would rather have it between 45-55%. Wasn't expecting the heat from the dehumidifier to warm our comfortable 69°/70° room to 77°! Unit has a Set setting, along with Continuous and Max. How is the exhaust (warm/cold) going to be during each of those settings? Which will keep humidity set at a specific % and limit heat? Thanks, in advance. Loved that you included a real-like example of the frosting of the coils and the melting of the ice.

    I have an idea, take the air conditioning unit from a old car. Run three fans on it. One for the compressor and hot coil. To blow heat. Separated by a insulated wall that holds another fan system to blow cold air/ keep drinks cold. Separate the drink compartment from the cold coil to allow the dehumidifier to act as a water generator for the car... this gives several benefits, a mild heat source when engine is off, cold storage, and water collection for the house... add a charge controller onto the orginal battery and run that to another seperate 12v marine battery with a decent reserve capacity. Or an entire battery bank if you want to go the extra mile. Add in a wind turbine to your car system and boom mobile power and water generator for simply running your car as you would anyhow (food delivery and commercial industries are missing out!!). Total cost would be miniscule. As low as 20 for the charge controller, 160 per battery, 50 for the inverter, 30-50 for the coils, and 0-150 for the air conditioning unit... another side note consider running the water reservoir to the underneath the hood, thermosyphoning the water for extra heat and hot water on the go. Plus water running under the hood will be smart to run alongside the heat system coils. Allowing additional cooling to the engine compartment and increased free heat and hot water to the system

    Ive always wanted to make an air-conditioner out of one of these just for fun just to see if it can be done. Place the warm coil on one side of a wall with a fan blowing out, and place the cool side on the other side of the wall with a fan blowing in, with a drainage tube for water of course. Seems feasible.

      @@ZachFields Im building a travel camper and dont really want to install an ac unit in the roof and dont really want a mini split (although that may end up being the best solution), but Id really like to build my own sort of heatpump with reversing valve using a fridge compressor or something smaller. I know they sell smaller compressors. But I could grab a vehicle fan shroud and an electric automotive fan for both exhausting the hot side, and another one to act as the blower for the cold side. I mostly just think it would be a fun project but I dont have any hvac experience so Im intimidated

  • @daniellapain1576
    @daniellapain1576 Год назад

    So I technically you could make a 12v-24v dehumidifier by just swapping out the compressor for a boat refrigerator compressor. My goal is to design one that uses the least energy but pumps out the most water so it can run from solar power. So I guess it would have to turn off after icing at 3 quarters of the way for the most water without damage. The knowledge of what the internals do is extremely helpful. With some solid state fans it could run with very little electricity in a slim case too.

    Nice video Zack thanks for showing the internal workings. I noticed my machine it seems to be dripping the parts at the edges for the copper coil winds around. Is that normal? I mean the part that's not covered by the aluminum fins. Also I noticed something strange in my collection bucket the water that comes out has this sort of blackish grayish residue when I pour out the water. I cleaned the bucket but it seems to be coming from the inside of the machine because I can see it on top of the drip tray where the hole is. It wipes off relatively easily with a paper towel and it almost seems more of like a sort of a graphite than it does actually seem like mold but I guess it could be some type of mold. I've had a few other dehumidifiers and they don't seem to have the same problem that this one does so I guess I need to open it up and give it sort of a deep cleaning but I'm not really mechanically inclined so I'm a little hesitant to get too far into it. I'm ready to open it up the next time the bucket is full and see if I can get some extra gunk out behind behind beyond what the filter is

    So if I have a dehumidifier and I bypass the air after it passes over the cooling coil and force back into the room
    And if I add an additional fan to draw outside air over the hot coil , and then exhaust it back outside , I would then cool the room and have an a/c ?

  • @Paragon_Reason
    @Paragon_Reason Год назад

    Great explanation.
    Me being novice and wanting to learn it leads me to a questions.
    Is there not a way to cool the air without using a compressor, bc there is heat made by compressor as well as it increased the temp of "coolant" to 200degrees in the example.
    Does it have to be liquid in order to disperse the coolant at a cold temperature?
    Is there no way to have a coolant that sits below room temp in a natural state and cycle that in front of the coils/fan to cool the air?
    Another question would be.
    Are there any systems that r designed in such a way that the would essentially put the Warn-Liquid compressor coil 'under' the Liquid misting cooling coil, which would drizzle the icey cold water, over the Warm coils to lower the temperature a tad, but keep coolant a liquid, but utilize the off-heat better. I know it sounds like the ramblings of a madman but my mind wanders when it's trying to figure things out.

    • @MuffinKingStudios
      @MuffinKingStudios 3 года назад

      Perhaps it only uses the cooling to condense the water onto the plate? Similar to the cold water bottle reference in the video. Or maybe it's one of those thermoelectric generators that produces a temperature difference on either side of a metal to condense the water?
      I'm no expert but I think you raised a great point.

  • @razordu30
    @razordu30 2 года назад

    This is a really great explanation. So this gives me an idea; maybe you could weigh in on it?
    In RVs and Vanlife, how to heat during the winter is often a tough decision. One of the heaters is a catalytic heater that uses propane. This has the advantage of being quiet, safe(ish), and energy efficient. The major drawback is that a byproduct of the process creates moisture, and in a smaller space this can get pretty uncomfortable. The solution is to provide enough outside air exchange to let fresh air in and moist air out, but obviously that's an inefficiency.
    So my question: based on how a dehumidifier works, does this mean I could essentially duct cold air from outside the RV through a pipe with fins and then back out again, and it would dehumidify the air? Or even have some kind of antifreeze stored outsidepiped through a copper baseboard contraption? Since this would also cool the RV a little, would this be less efficient than exchanging air?

    • @ZachFields
      @ZachFields  2 года назад

      @razordu30
      Brilliant idea! I've run into this same scenario on short weekend car camping trips. A few things that come to mind with this setup is that there would need to be a high exchange rate of air moving through that duct (as you mentioned), but also a high air flow across the inside coil. My guess would be that in order for this to work, the temps outside would have to be well below freezing.
      The thing about a dehumidifier is that there is no net thermal gain or loss across the coils. There is a net thermal gain in heat from the motor. With the setup you mentioned there IS a net loss in temp. That said, however, the only energy consumption is that of a few fans. Again, the lower the outside temperature the more efficient it would be but also the greater the need.
      There would be some bugs to work out, but you may well be onto something here. When running those catalytic heaters, is there a need for fresh air exchange to replenish oxygen?

    • @charliec.8303
      @charliec.8303 3 года назад

      I’m sorry, that sucks! I don’t believe dehumidifiers will kill mold spores. They will just lower the humidity to a level that makes it difficult for mold to grow. That will be important over the long run. In the meantime, killing mold where you see it with various cleaners is helpful, as well as using an air filter or good filter insert for your HVAC (air conditioner) system, if you are having allergies to the mold.
