The system will be constructed on an existing building on the MRS property that will ultimately be used as a pre-cooling station. Once the harvested crops are in the building, observations will take place to review the efficiency of the Geothermal vs. the current traditional HVAC system in regards to the speed and quality of pre-cooling efforts.<br />

The Geothermal expert guest speaker will discuss the characteristics, development, and utilization of Geothermal Resources and their many benefits.<br />
<br />
We encourage anyone in Western NC to join us for the presentation, wether industry professionals, those in the agriculture industry, educators, and all other interested in the topic of Geothermal Resources. These types of HVAC systems can offer impressive savings on energy and money. The info sessions will explain in depth the benefits and how it works, and will be followed by a question and answer portion open to attendees.<br />
<br />
Farmers of Western North Carolina can benefit greatly from Geothermal Systems as a way to pre-cool their crops, which can significantly extend the shelf life of their products in comparison with traditional HVAC systems that are currently being used in commercial buildings to remove the ground heat from crops.<br />

<br />
Geothermal or ground source heat pumps are typically used to condition room air for the comfort of its inhabitants. This temperature is always near 70 degrees. In order to bring a crop to a ideal temperature for storage the room temperature of the precooling area needs to be much less then 70 degrees.<br />
<br />
There are several things that will contribute to the interior temperature of the Precooling area before it is conditioned. The walls must also be super insulated to maintain the temperatures we are trying to reach. The crop that is brought into the area will be at the exterior temperature. Large quantities of product will certainly add to the load for the cooling equipment. This temperature will be near 80 degrees or higher for most of the crops that are harvested in the summer months.<br />
<br />
Bringing large quantities of 80 degree crop to 40 degrees demands quite a lot from the cooling equipment.<br />
<br />

<br />
If the gray building is the Precooling Room we are much better to draw temperature change from the ground temperature than from the air temperature.<br />
The high air temperature (80)during harvest time for most WNC crops would certainly be more costly to cool than the constant ground temperature(57).<br />

Geothermal Technologies are not new...</h1>
<br />
The challenges of making geothermal a mainstream technology center around education. The technology is a guaranteed energy reduction if installed correctly. The challenge lies in educating prospective clients and contractors in its use. This is one of the things that we are focusing on at Haywood Community College. We will give the public answers to the questions that they ask. We can teach probable contractors what they need to know. <br />

<br />
For those of you who are experts in this area forgive me if you are reading:<br />
<br />
Crops that use Precooling in WNC, or Postharvest Precooling Methods<br />
<br />
Apples<br />
Berries<br />
Peppers<br />
Cabbage<br />
Broccoli<br />
Onions <br />
Blueberries<br />
Green Beans<br />
Field peas<br />
Tomatoes<br />
<br />
Methods of Precooling, We can use forced air, hydrocooling, or still air. Each of these methods is different and applies to different crops. For example: Apples respond well to hydrocooling but tomatoes need room cooling. Tomatoes are very sensitive to chilling. A geothermal unit can assist in each of these areas because it simple allows the owner to bring a the temperature of the cooling fluid, air or water in this case to a temperature needed by the commodity (crop). Each crop needs a different temperature but the temperature change needed of the cooling fluid will always be less when using geothermal. This temperature difference is referred to as the DELTA T. Delta T from 58 to 50 requires less energy than Delta T from 82 to 50. The temperature of the earth is constant (for the most part) at depths fro 50 to 200 feet. We utilize this in any type of ground source heat pump.<br />
<br />
The challenge at this point is to create equipment that will accomplish this precooling in a method that is cost effective and accessible to people in WNC. We are currently using ground source heat pumps for residences and commercial buildings but people prefer to be at 70 degrees and tomatoes like it more near 40-50 degrees depending on their maturity. This being one of the challenges of the progress,<br />
