摘要:
A control unit 65 is added to the environmental tester 10 including a thermostat-humidistat container 1, an air conditioner 8, a first temperature and humidity sensor 9 for measuring temperature and humidity in the thermostat-humidistat container 1, a controller 6 for receiving a first signal from the first temperature and humidity sensor 9 to control the air conditioner 8. The control unit 65 includes a second temperature and humidity sensor 5 configured to measure the temperature and humidity distribution in the thermostat-humidistat container 1, and an additional unit 60 configured to receive the first signal and set values for the temperature and the humidity from the controller 6, and receive a second signal from the second temperature and humidity sensor 5, compute a correction value from the received first signal, second signal, and set values, and send the correction value to the controller 6.
摘要:
A controlling section 41 receives determined temperature and humidity values, set temperature and humidity values, a heating electric power value, and a humidifying electric power value from a body controller 30. A comparison and determination section 46 compares the heating electric power value and the humidifying electric power value with respective predetermined reference electric power values, and when at least one of the heating electric power value or the humidifying electric power value is less than a corresponding one of the reference electric power values, the comparison and determination section 46 outputs an anomaly signal indicating that the cooling capacity of a refrigeration apparatus 22 has been reduced.
