Then, the atmosphere around the outer tube 1 is heated or cooled, but at this time, the inner tube 3
The cooling / heating medium has a high temperature (low temperature in cooling) on the supply side and is radiated to a low temperature (high temperature in cooling) on the discharge opening end side, but conversely the heat medium flowing direction in the outer tube 1 is reversed. So
The heat medium in the inner pipe 3 and the heat medium in the distribution space 7 mutually radiate and absorb heat, so that the heat energy released from the outer periphery of the outer pipe 1 becomes substantially uniform over the entire length of the pipe, and in the case of cooling and heating, it becomes The atmospheric temperature difference on the discharge side is reduced or almost disappeared, and the temperature of the entire cold / greenhouse becomes uniform.

端（イ）側より供給される。The tip (b) side of the inner tube 3 is opened to form a discharge port 4, and the end of the outer tube 1 on the same side is a closed end 6. As a result, the cooling / heating medium (refrigerant or heating medium) supplied from the base end portion (a) side of the inner pipe 3 is discharged from the discharge port 4 side into the closed end of the outer pipe 1 and the outer periphery of the inner pipe 3. It flows through the space 7 formed between the inner circumference of the outer tube 1 and the inner circumference of the outer tube 1, flows in the direction opposite to the flow at the time of supply, and is sent to the base end portion (a) side of the outer tube 1 for heating or It is heated or cooled in a cooling unit (neither is shown) and is again supplied from the supply end (a) side of the inner pipe 3.

行い、栽培室内の温度は均一になる。When the cooling / heating medium is circulated, for example, in the case of the heating medium, the heating medium of the inner tube 3 has a high temperature at the base end (a) side and a low temperature at the tip end (b) side, but has a space part. The temperature of the heat medium flowing through 7 is opposite on both sides (a) and (b). As a result, the temperature of the heat medium on the outer circumference of the inner pipe 3 becomes a temperature that is substantially balanced between both ends (a) and (b) due to the heat exchange with the heat medium of the inner pipe 3, and the temperature difference becomes extremely small. Then, the outer tube 1 radiates heat (or cools) substantially uniformly over the entire length, and the temperature in the cultivation room becomes uniform.

イルム製なので上記熱交換も効率よく行われる。At this time, since the temperature gradients of the inner pipe 3 and the outer pipe 1 on the base end (a) side and the tip end (b) side of the duct are opposite, the inside of the inner pipe 3 and the inside of the space 7 are inclining. As a result of heat exchange of the cooling / heating medium, the temperatures of the cooling / heating medium discharged from the discharge holes 8 of the outer tube 1 are substantially equal to each other over the entire length or there is almost no temperature difference. Further, since the outer pipe 1 and the inner pipe 3 are both made of a thin plastic film, the heat exchange can be efficiently performed.
