The condenser in the refrigeration circuit is cooled by air.
A device which prevents the humidifying heater from overheating when
humidifying water is low or empty.
A control method which keeps temperature and humidity inside the
chamber constant.
A phenomenon whereby moisture in the air forms a dew. Dew forms on
an object if its temperature is below the dew point determined by air tem-
perature and humidity. For example, the dew point for an air temperature
of 85°C and a humidity of 85%RH is 81°C.
The air temperature measured by a dry-bulb temperature sensor.
The area inside the test area up to 1/6 the distance from walls in all driec-
tions.
A terminal which outputs a signal when the chamber is stopped by trou-
ble. The terminal is designed to set off a buzzer or bell in the area around
the chamber or to send an alarm signal to a remote point.
The heat generated by specimens inside the chamber. The name comes
from the fact that this heat acts as a load on the chamber.
Water used to humidify the test area. Water is kept in the humidifying
tray. The humidifying heater evaporates it to humidify the test area.
The variation between the mean maximum humidity around the geomet-
ric center of the chamber. Not the same as the difference from the true
humidity.
The range of humidity that can be reproduced inside the chamber.
The difference in humidity between the geometric center of the chamber
and any arbitrary point in the effective area.
The lowest temperature that can be reproduced inside the chamber.
The maximum amount of electric current supplied to the chamber
through the power cable when the chamber is running within the temper-
ature and temperature-humidity control range. With a 3-phase power
supply, the maximum current is that which flows through any one of the
wires. Maximum current is measured in amperes (A).
A device for preventing temperature inside the chamber from rising
abnormally high because of chamber trouble or heat generated by speci-
mens.
A terminal to charge specimens, which is interlocked with the chamber
power circuit so that power to specimens is shut OFF in the event of
chamber trouble.
The variation between the team maximum temperature and mean mini-
mum temperature around the geometric center of the chamber. Not the
same as the difference from the true temperature.
