。The stored silica gel is 250 ky, and the heat pump is 2
A heating system with an output of 4000 kcal/h and an air flow rate of 14 m7 m1n was installed in a greenhouse, and when the indoor temperature reached 20'C or higher during the day, the heat pump was operated to store heat. It took about 5 hours of driving. A heat pump heat collector 7 is placed in the greenhouse, and heat is collected from the air in the greenhouse, and the heat pump heat radiator 3 heats the introduced air to approximately 0°C; The moisture released from the silica gel 4 is released into the greenhouse, but in principle, the water dispersed in the heat pump collector 7 condenses, so the change in humidity in the greenhouse due to the operation of this system is At night, the heating temperature setting was set to 8°C, and when the temperature inside the greenhouse reached 8°C, fan 5 was turned on and the heat pump was stopped.) Heat dissipation operation was performed.

After 9 hours, the temperature was about 11°C and the relative humidity was about 60%. The amount of heat radiated into the greenhouse was approximately 12,000 kcal from measurements of the temperature difference between the entrance and exit of the heat storage tank and the air volume during this period. The amount of water absorbed by the silica gel was calculated to be approximately 227, confirming the moisture-proofing effect.

定するものではない。As described above, the heating device of the present invention is characterized in that it stores heat by operating a heat pump using surplus solar energy in the greenhouse during the day as a heat source, and has a dehumidifying effect as well as a heating effect at night. Compared to nighttime operation using air conditioners, the heat source is the hot greenhouse air during the day, which increases efficiency and saves energy, while at the same time making it possible to reduce high humidity at night through dehumidification. In the example, the heating system was tested using only air suction ports from inside the greenhouse, but it is also possible to take in air from outside the greenhouse if necessary. Furthermore, in this example, experiments were conducted in a humid greenhouse during tomato cultivation; however, in the case of use in a dry greenhouse, humidification means may be provided at the inlet of the heat storage tank during heat dissipation operation.
It is effective to humidify the intake air and then introduce it to the heat storage tank. Further, in this embodiment, granular silica gel was used as the moisture absorbing material, but the moisture absorbing material is not limited to silica gel and may be any material that can be dried and regenerated at the output temperature of the heat pump. The shape of the moisture absorbing material, the structure of the heat storage tank, etc. do not limit the gist of the present invention.
