METHOD FOR LAYING WARM WATER PIPING IN ISOLATED BED CULTIVATION FOR AGRICULTURE

摘要

PPROBLEM TO BE SOLVED: To provide a method for laying warm water piping in an isolated bed for agriculture by which a coefficient of utilization of heat is improved, and air vent is facilitated. PSOLUTION: The whole of a sending pipe 2, a returning pipe 3 and branch pipes 4, constituting the piping in an installation for cultivating a flower or a vegetable are formed aboveground in the hot water-circulating installation 1 in the isolating bed for the agriculture. The positions of both the sending and returning pipes are higher than those of the branch pipes in the isolating bed 7, and regulated so as to have the height not disturbing the passage of an operator. As a result, the hot water piping based on the method has a shape as if the branch pipes 4 are suspended by both main pipes at side faces of the piping. PCOPYRIGHT: (C)2003,JPO
