Where Should You Put Your Walk In Coolers?

The location of your walk in cooler is crucial if you are building one that will stand up to the elements. This is especially important if you live near a hot climate.

Your commercial cooler will be happier in direct sunlight, just as you are more comfortable in the shade during summer. This is crucial for energy savings. Direct sunlight cools coolers at 70% less than those in the shade.

To get the best performance, keep your cooler in a protected place.

  • In an existing building
  • Under a tree
  • To the north of a barn
  • An existing structure has an overhang.

You should make sure that your cooler has an open-vent roof if you have an overhang.

A small cooler with a flat roof may be structurally sound, but they are not designed to protect the sun. A standard peaked roof that has ventilation above the cooler ceiling can shade it and provide passive ventilation. This will help to keep the coolant circulating and save you money.

Notice: Heat rises. This is why we place twice the spray foam insulation on the roof of a house than the walls. Cold air sinks, so keep your own cooler roof from direct sunlight. You can still put spray foam insulation on the roof just like you did on the walls. This will help you save money on both construction costs and ongoing operating expenses.

Let it hang free, but make sure it’s not making contact with any metal and is not in the direct pathway of the cold air coming from the A/C. Place the wire labeled “FIN Sensor” into the front cooling fins of the A/C window unit. Gently place the sensor as low as possible, but ABOVE the first horizontal cooling tube.

CoolBot provides many guides to help you build a well insulated room, trailer, or other space. CoolBot does the rest. If you already have a through-wall unit, don’t hesitate to use it. But if you’re purchasing a new A/C, you’d be better off with a window unit or a mini-split.
