Dec 29, 2015 · The heat loss for a greenhouse is estimated by multiplying the surface area, a heat transfer coefficient and the air temperature difference between inside and outside. This equation assumes no solar gain and is used to calculate the size of the heating system needed for the coldest night. HL = A x U T Where:HL = Heat loss (Btu/hr).

The air passing through the tubes is warmed by the soil that has a higher temperature than the air. During the summer the system can be used to cool building space by drawing the heated air in the greenhouse through the buried tubes and then returning it to the building. The heat is absorbed by the cooler earth. Greenhouse & Floriculture:Greenhouse Heat Distribution Heat from water can be distributed by bare steel pipe, fin radiation, root zone heat or water to air unit heaters. Bare steel pipe is rarely used in U.S. designed greenhouse heating. Its low heat output, large volume of water and space requirements are disadvantages. It has been replaced by fin pipe. Fin pipe is best located along the perimeter
systems which are applied to greenhouses:1. Finned pipe 2. Standard unit heaters 3. Low-temp. unit heaters 4. Fan coil units 5. Soil heating 6. Bare tube.
