TEMPERATURE CONTROL SYSTEM FOR PLANT FACTORIES, PLANT FACTORY, TEMPERATURE CONTROL METHOD, TEMPERATURE CONTROL PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

Disclosed is a temperature control system for plant factories, which comprises: a temperature control device (8) which controls the temperature of a cultivation room (2); a temperature/humidity sensor (4) which measures the temperature and the humidity within the cultivation room (2); a temperature sensor (5) which measures the temperature of a plant (7) that is cultivated in the cultivation room (2); a dew condensation determination unit (642) which determines whether dew condensation occurs on the plant (7), which is cultivated in the cultivation room (2), or not on the basis of the temperature and the humidity within the cultivation room (2) measured by the temperature/humidity sensor (4) and the temperature of the plant (7) measured by the temperature sensor (5); and an indoor temperature increase instruction unit (646) which has the temperature control device (8) increase the temperature of the cultivation room (2) when the dew condensation determination unit (642) has determined that dew condensation had not occurred on the plant (7), which is cultivated in the cultivation room (2). Consequently, the temperature of the cultivation room is increased, while surely preventing the occurrence of dew condensation.
