きず、加湿器による加湿効率も損なわれていた。That is, when the temperature of the supplied water is lower than the dry-bulb temperature in the growing chamber, the heat of the air in the growing chamber is removed by the spray water of the humidifier, and the temperature in the growing chamber falls.
The temperature control in the growth chamber by the air conditioner is disturbed, the accuracy of the temperature control is impaired, and further cooling dehumidification is caused, and the air in the growth chamber cannot be humidified to a desired humidity. Humidification efficiency due to was also impaired.

のである。Although the specific construction of each method of the humidifier 30 is well known and its detailed description is omitted, the features of each method will be briefly described below. In other words, the water spray method is a method in which water is atomized and evaporated in the air to be humidified, and the humidification also has an effect of cooling, and the spray amount is large even with a small electric power. The steam type is
It is a humidifier that blows out steam and can perform aseptic and clean humidification, highly accurate humidification, and does not lower the temperature of air. In the vaporization method, air is applied to a wet humidifying material to humidify it by evaporation, and it is possible to prevent a low humidity due to a gradual change in humidity and to perform clean humidification.

The water for humidifying the air in the growing room 12 is supplied by the water supply pipe 40.
The supply water is supplied to the humidifier 30 by means of the heat exchanger 50, which is first introduced into the heat exchanger 50 provided in the middle of the water supply pipe 40. Then, the supply water for humidification is heat-exchanged with the air on the side of the growing chamber 12 by the heat exchanger 50. Since the heat exchanger 50 is installed near the suction port 18 and the air on the side of the growing chamber 12 is just blown against the heat exchanger 50, the supply water is in the core 53 of the heat exchanger 50. When passing through a tube or the like, the heat exchange between the supply water and the air on the side of the growing chamber 12 is performed quickly and smoothly.

できる。As shown in FIG. 2, the heat exchanger 50 according to the present embodiment does not require dedicated energy for heat exchange, so that the structure can be simplified and the installation space and cost can be increased. Absent. Further, since the heat exchanger 50 has the amount of water held in the first tank 51 and the second tank 52 thereof, which is commensurate with the amount of humidification required in the humidifier 30,
The heat-exchanged supply water can be stably sent to the humidifier 30.

態が生じることもない。During heat exchange in the heat exchanger 50, when the temperature of the supply water is lower than the temperature of the air on the growth chamber 12 side, the heat of the air on the growth chamber 12 side is transferred to the supply water, and conversely. When the temperature is higher, the heat of the supply water is transferred to the air on the growth chamber 12 side, and in any case, the temperature of the supply water approaches the temperature of the air on the growth chamber 12 side. As a result, the difference between the temperature of the air on the side of the growing chamber 12 and the temperature of the water supplied to the humidifier 30 is reduced as much as possible.
The temperature of the inside of the growth chamber 12 does not drop due to the heat of the side air being taken away, and therefore cooling dehumidification does not occur. Further, the humidifier 30 does not cause a situation in which the temperature inside the growing chamber 12 rises.

(t W in FIG. 4), such supply water is used. (10 ° C.) is considerably lower than the dry-bulb temperature (25 ° C.) of the air on the growth chamber 12 side, the state change on the air diagram becomes as shown by the straight line L 2 , and cooling dehumidification occurs. . When the feed water is heated to 40 ° C. with an electric heater or the like, the state change on the psychrometric chart becomes as indicated by the straight line L 3, and the dry-bulb temperature of the air in the growing chamber 12 rises. Therefore, the temperature control in the growth chamber by the air conditioner 20 is disturbed and the accuracy of temperature control is impaired.
