    摘要: A control unit is added to the environmental tester including a thermostat-humidistat container, an air conditioner, a first temperature and humidity sensor for measuring temperature and humidity in the thermostat-humidistat container, a controller for receiving a first signal from the first temperature and humidity sensor to control the air conditioner. The control unit includes a second temperature and humidity sensor configured to measure the temperature and humidity distribution in the thermostat-humidistat container, and an additional unit configured to receive the first signal and set values for the temperature and the humidity from the controller, and receive a second signal from the second temperature and humidity sensor, compute a correction value from the received first signal, second signal, and set values, and send the correction value to the controller.

    摘要: A temperature characteristic evaluation method includes the steps of acquiring temperature data, ambient temperature data, and internal temperature data are acquired. By changing at least one of the set temperature and the ambient temperature, a plurality of combinations of the set temperature data, the ambient temperature data, and the internal temperature data is obtained as a plurality of temperature data groups. A difference between the ambient temperature data and the set temperature data in each of the plurality of temperature data groups is calculated as the first difference. A difference between the internal temperature data and the set temperature data is calculated as the second difference. The combinations of the first and second differences are obtained as difference groups. The plurality of difference groups for the plurality of temperature data groups is approximated in a linear function, and the linear function is obtained as a temperature function.

    摘要: An example control method is a method for controlling an air conditioner to turn a state in closed space to a predetermined target state. The control method includes: setting a target value for controlling a physical quantity; measuring the physical quantity at different positions in the closed space, and calculating a moving average of measurements of the physical quantity measured at each of the different positions; and controlling the air conditioner in such a manner that a median between the maximum value and the minimum value of the plurality of calculated moving averages is the target value.

    摘要: A plurality of fluorescent lamps 30 are in a decentered layout so as to be placed in a peripheral part of an upper space of an environmental test chamber 11 above a sample loading surface 21. The irradiance distribution of light from the fluorescent lamps 30 over the sample loading surface 21 is in the range of ±25% relative to the irradiance at the center of the sample loading surface 21.
