A plastic greenhouse with a circulating path for heating and cooling in which a cold wind and hot wind are selectively supplied to heat and cool the interior of a plastic greenhouse is provided to prevent the collapse of the plastic greenhouse and the buildup of snow as well as frost from being formed on the surface by thawing snow accumulated on the surface during the winter. In a plastic greenhouse comprising a plurality of vertical support rods(1) and horizontal support rods(2) and vinyl film(3) for covering the exterior of them, a circulating path(10) for heating and cooling the interior of the plastic greenhouse is formed inside the vinyl film which covers the exterior of the plastic greenhouse. The circulating path is hollow, welded by high frequency and in communicated with each other in zigzag form. |
