Document Type and Number:
Japanese Patent JP6120585
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device having the following features: a hot air heater proposed by the applicants is utilized as a relay base for supplying supply CO2 and conditioned cold or hot air to a greenhouse in which a hot air heater, a carbon dioxide gas generator and a heat pump are utilized so as to create an optimal growth environment for crops in the greenhouse; a complex agricultural machine is utilized effectively; a construction of hot air heater in the machine is further developed in the invention and effectively utilized; in both of the cases where the hot air heater is operated and stopped, a passage, a fan and a duct arranged at the outlet of the passage are effectively utilized so that CO2 and mixed air is efficiently supplied to crop.SOLUTION: The invention provides a device for improving crop environment in which a hot air heater is utilized. In a greenhouse, a hot air heater, a carbon dioxide gas generator and a heat pump are arranged. Each of tubes from the carbon dioxide gas generator and heat pump is connected to an inlet port of the hot air heater. CO2 and/or hot or cold air from each of the tubes is sent to the hot air heater. A fan of the hot air heater, an inner passage and an outlet are utilized. From the duct connected to the outlet, the CO2 and/or hot or cold air is supplied to the greenhouse.
