<p>PURPOSE: To save energy by performing controls in such a way that the heating capacity is determined corresponding to output values of humidifying signals so that the heating capacity becomes low when output values of humidifying signals are large. CONSTITUTION: A temperature sensor 7 and a humidity sensor 8 are installed at the entrance of a test room 1. Signals detected by the temperature and humidity sensors 7 and 8 are input to temperature and humidity controllers 10 and 11 of an environment test device. The controllers 10 and 11 send humidifying and heating outputs to a humidifier 3 and a heater 5 so that electric power to be applied is regulated and the humidifying and heating amounts are controlled. Thus, the temperature and humidity of air to be sent to the test room 1 are controlled. As the heating capacity of a dehumidifier 9 is controlled corresponding to the humidifying outputs, the regeneration temperature is lowered to reduce the dehumidifying capacity when the humidifying capacity is high, resulting in a reduction of the heating amount. As a result, energy saving of the environment, device can be attained.</p> |
