He just built a marine AC unit…. Exactly how they work. And pretty sure if you use a large ground loop that’s how geothermal works too. The clever thing is to do this at house size and use a pool as the water source…. Then you have a pool heater as well.
My AC runs a lot colder since you showed me this trick. I rigged up a water jug to drip right on the radiator, just gotta refill it every 4 hours during the day.
We used portable AC units for interior rooms in a university which were hooked up to sinks for cold water sources. They worked great and used about 1/4 gal of water per mins
Are the fluids travelling through the block in opposite directions? That is supposed to help with heat transfer/efficiency. Also- you can use electronic duster “canned air” as a coolant (R152) vs R134, and you can use less of it (2/3 by weight of 134 iirc)
@@ianbuilder What is your math on that? All you have eliminated power-wise was the condenser fan. You are still running the compressor and you still need a blower for the evap coil. Condenser fans usually only make up about 10-20% of the power consumed in an AC unit. Supply fan motors are also about 10-20% and the compressor is about 70-80%. And, you are either going to waste a ton of water on an open loop, or you still need a way to cool the water on a closed loop. So you will need a fan/radiator setup somewhere to reject the heat from the water. All you did was make this unit a little quieter.
I want to convert a portable AC into water cooled like this , but i dont have the knowledge about air conditioner and the welding of copper tube, this video is great for me
@@racerdude7149 Not everyone shares your IQ. Most people assume that one way or another the water will have enough cooling surface to maintain temperature. This is a way of using water cooling without cutting the refrigerant pipe.
Sizing a Water-Cooled Heat Exchanger for 12,000 BTUs Understanding the Basics Before diving into calculations, it's essential to understand the key parameters: * Heat Load: The amount of heat to be removed, which is 12,000 BTUs in your case. * Inlet and Outlet Temperatures: The temperature of the water entering and leaving the heat exchanger. * Water Flow Rate: The volume of water passing through the heat exchanger per unit time. * Heat Transfer Coefficient: A measure of how efficiently heat is transferred between the two fluids. Steps Involved: * Determine Inlet and Outlet Water Temperatures: * This depends on your application. For example, if cooling a machine, you'd want to determine the maximum allowable outlet water temperature. * A typical range might be 70°F to 90°F. * Calculate Required Water Flow Rate: * Use the following formula: * Q = m_dot * Cp * ΔT * Where: * Q = heat transfer rate (BTU/hr) * m_dot = mass flow rate of water (lbm/hr) * Cp = specific heat of water (BTU/lbm°F) * ΔT = temperature difference between inlet and outlet water (°F) * Rearrange the formula to solve for m_dot. * Estimate Heat Transfer Coefficient: * This depends on the heat exchanger type (shell-and-tube, plate, etc.), materials, and flow conditions. * Typical values can range from 100 to 1000 BTU/hr-ft²-°F. * Calculate Required Heat Transfer Area: * Use the following formula: * Q = U * A * LMTD * Where: * Q = heat transfer rate (BTU/hr) * U = overall heat transfer coefficient (BTU/hr-ft²-°F) * A = heat transfer area (ft²) * LMTD = log mean temperature difference (°F) * Calculate LMTD based on inlet and outlet temperatures of both fluids. * Rearrange the formula to solve for A. * Select a Heat Exchanger: * Use the calculated heat transfer area to select a heat exchanger from manufacturer catalogs or consult with a heat exchanger specialist. * Consider factors like pressure drop, materials compatibility, and cost. Additional Considerations: * Fouling: Over time, deposits can form on the heat exchanger surfaces, reducing efficiency. Consider fouling factors when calculating the heat transfer coefficient. * Pressure Drop: Ensure the selected heat exchanger has an acceptable pressure drop for your system. * Material Compatibility: Choose materials compatible with the fluids involved. * Cost: Balance performance requirements with budget constraints. Example: Assuming: * Inlet water temperature = 70°F * Outlet water temperature = 90°F * Desired water flow rate = 10 gallons per minute (gpm) * Estimated heat transfer coefficient = 300 BTU/hr-ft²-°F You can calculate the required heat transfer area and select a suitable heat exchanger. Note: This is a simplified overview. Accurate heat exchanger sizing often requires detailed calculations and consideration of various factors. Consulting with a heat exchanger expert is recommended for complex applications. Would you like to provide more specific information about your application, such as the type of fluid being cooled, desired temperature, and available water supply? This would help in providing a more accurate sizing recommendation.
Nice modification. I think you can cool the water using a high efficient radiator or use the radiator used on the AC so that you can extend the heat away. This way, no window rooms can have AC now. I have a batch freezer used to make ice cream and it is water cooled which water is wasted to drain, was thinking on using a radiator to cool the water and place it outside/different location.
How to use water to cool if i have no water tap? Can i use a water pump instead? How to get cool water if i have no water tap? Do i need to add coolant liquid to the water ?
Bro, when people want to water cool AC units...this is just the start. Once you get some cooper tubes on that thing it'll be sick, however, be careful with refrigerants, compressors can be oicky about what thyley want to oump.
@@ianbuilder Please tell us where we could see that you used "butane". At 6:39 we can clearly see you used a can of 134a with a chemical formula of C2H2F4. No where in this video do we see a can of R600a with a chemical formula of C4H10 (butane / isobutane) For the ignorant, the main difference between these two refrigerants, 134a is nonflammable while R600a is flammable. Also, why wouldn't you use propane rather than butane? R600a (C4H10) costs $0.65 / oz, while propane (C3H8) costs $0.01 / oz

whats the difference in watt? is it more efficient in power consumption?
yes, it was close to 80% more efficient

Ok now we got it working 😂😂
so true
Did you ever use the hot side to heat your pool?
Pre cool the water with ground loop geothermal.
9:39 been a year, did you abandon the split unit project?
Or something to look forward to next summer?
It would be easier to put the condenser heat exchanger in a tank of water even if you have to make the tank out of plywood and J B weld.
And then when the water tank gets warm?? Are you going to make a water chiller for that tank?

Sizing a Water-Cooled Heat Exchanger for 12,000 BTUs
Understanding the Basics
Before diving into calculations, it's essential to understand the key parameters:
* Heat Load: The amount of heat to be removed, which is 12,000 BTUs in your case.
* Inlet and Outlet Temperatures: The temperature of the water entering and leaving the heat exchanger.
* Water Flow Rate: The volume of water passing through the heat exchanger per unit time.
* Heat Transfer Coefficient: A measure of how efficiently heat is transferred between the two fluids.
Steps Involved:
* Determine Inlet and Outlet Water Temperatures:
* This depends on your application. For example, if cooling a machine, you'd want to determine the maximum allowable outlet water temperature.
* A typical range might be 70°F to 90°F.
* Calculate Required Water Flow Rate:
* Use the following formula:
* Q = m_dot * Cp * ΔT
* Where:
* Q = heat transfer rate (BTU/hr)
* m_dot = mass flow rate of water (lbm/hr)
* Cp = specific heat of water (BTU/lbm°F)
* ΔT = temperature difference between inlet and outlet water (°F)
* Rearrange the formula to solve for m_dot.
* Estimate Heat Transfer Coefficient:
* This depends on the heat exchanger type (shell-and-tube, plate, etc.), materials, and flow conditions.
* Typical values can range from 100 to 1000 BTU/hr-ft²-°F.
* Calculate Required Heat Transfer Area:
* Use the following formula:
* Q = U * A * LMTD
* Where:
* Q = heat transfer rate (BTU/hr)
* U = overall heat transfer coefficient (BTU/hr-ft²-°F)
* A = heat transfer area (ft²)
* LMTD = log mean temperature difference (°F)
* Calculate LMTD based on inlet and outlet temperatures of both fluids.
* Rearrange the formula to solve for A.
* Select a Heat Exchanger:
* Use the calculated heat transfer area to select a heat exchanger from manufacturer catalogs or consult with a heat exchanger specialist.
* Consider factors like pressure drop, materials compatibility, and cost.
Additional Considerations:
* Fouling: Over time, deposits can form on the heat exchanger surfaces, reducing efficiency. Consider fouling factors when calculating the heat transfer coefficient.
* Pressure Drop: Ensure the selected heat exchanger has an acceptable pressure drop for your system.
* Material Compatibility: Choose materials compatible with the fluids involved.
* Cost: Balance performance requirements with budget constraints.

* Inlet water temperature = 70°F
* Outlet water temperature = 90°F
* Desired water flow rate = 10 gallons per minute (gpm)
* Estimated heat transfer coefficient = 300 BTU/hr-ft²-°F
You can calculate the required heat transfer area and select a suitable heat exchanger.

Me: randomly searching aircon and im here now +1 Subscribe
Would it work, if you just place the condenser in a container, then used a pump to pump the water around, with tubing??
yep
@@ianbuilder What if you used a coaxial tube heat exchanger coil as condenser on a portable a/c, & used a radiator to watercool it
Nice job. very cool
can you make an ac like that that runs on 12v only?
Yes, it's the same machine, but yours use 12v DC to rum the compressor, it's the only diference.

as you could see i used butane instead
