Abstract: A electromagnetic wave test device includes: a reverberation chamber; a first antenna installed inside the chamber and radiating electromagnetic waves of a frequency lower than the chamber's first resonance frequency; a second antenna installed inside the chamber and radiating electromagnetic waves of a frequency equal to or higher than first resonance frequency; a power supply device connected between a grounding member and first antenna and feeding power to the first antenna; a dummy load connected between the grounding member and first antenna; a first power loss inhibiting unit having an impedance corresponding to an allowed value for power loss according to first antenna in a case wherein electromagnetic waves are radiated from the second antenna; and a switching unit including a first switching unit that switches a connection destination of first antenna to one of the dummy load and the first power loss inhibiting unit.

Abstract: A reverberation chamber capable of performing an EMS test having high accuracy in a wider frequency band is provided. There is provided a reverberation chamber including an electromagnetic stirrer, in which the electromagnetic stirrer includes: a first stirring blade; and a holding body disposed on a first wall face of the reverberation chamber, extending in a first direction intersecting with the first wall face, and configured to hold the first stirring blade, and the first stirring blade is electrically insulated from the first wall face.

Abstract: An air conditioning machine has a unit main body having an inlet port and an outlet port. The unit main body includes a cross flow fan, having a circular cross section, for introducing indoor air into the unit main body through the inlet port and blowing the air into the room. A heat exchanger is arranged on an indoor air introducing side of the cross flow fan and bent at a portion along a longitudinal direction of the heat exchanger at an acute angle. The heat exchanger has a front side heat exchanger located on a front side of the air conditioning machine and curved along the circular cross section of the cross flow fan and a rear side heat exchanger located on a rear side thereof.

Abstract: The air conditioning apparatus operable in heating and cooling operation modes for air conditioning a room has an external unit, an inner unit, and a control device. The external unit includes an external heat exchanger. The inner unit disposed in the room includes an inner heat exchanger which functions as an evaporator in the cooling operation mode whereas the external heat exchanger functions as a condenser. The control device has a thermistor disposed on the inner heat exchangers for detecting temperature of the inner heat exchanger, bias means for energizing the thermistor with a predetermined bias potential and term setting means responsive to the operation mode for setting first and second terms for allowing The energization of the thermistor. The the first term is longer than the second term when the inner heat exchanger functions as an evaporator. The control device also has a room temperature sensor disposed in the room for detecting room temperature.
