Hay Bale Walls Make Great Veggie Cooler
Hay bales and an old air conditioner were used to make a low-cost cooler for Ted and JoAnne Dawson, market garden farmers who use a refurbished school bus to deliver produce to customers (seen in Vol. 35, No. 6) and operate a farm stand at the end of their driveway. The cooler is used to keep their produce cool and fresh.
“I wanted a walk-in cooler, but they are expensive,” says Dawson. “Then I heard about the CoolBot (Vol. 32, No. 5) and how it could trick an air conditioner to cool a room down to 48 to 50 degrees.”
Dawson had an old air conditioner. The CoolBot micro controller would adjust the air conditioner fan and compressors to provide the cold temperatures. He still needed a room to cool.
Since they offer pony and carriage rides at their agritourism farm, they have plenty of hay bales. Knowing their insulation value, Dawson decided to use them to build a cold room inside a shed.
With the help of a buddy, Myrl Stone, Dawson cut a hole in an outside wall of the shed to hang the air conditioner, covering that wall with bales. He built the other three walls with more bales, enclosing an old door and doorframe in one wall for an entrance. Dawson dropped 2 by 4’s down from the rafters and tied bales to them. More 2 by 4’s became rafters for the cold room roof.
“We covered them with some 1/2-in. rigid insulation left from another project and covered that with more hay bales,” says Dawson. “When we were finished, we had a 6 by 7-ft. interior.”
The Dawsons used the cold room successfully in 2014 and plan to use it again this summer. He says it has worked well. Best of all, it was low cost. “I think we may have about $230 in the whole thing,” he says.
