An exterior machine room is provided for outside-the-room machine environmant tests, while an interior machine room is used for internal in-room machine environment testing.The test chamber enables weather resistance and endurance testing for each enbironmental condition.Outside-the-room machines in particular are tested for water spray, icing and thermal efficiency.
The Satake Acoustic Test Chamber reduces sound reflection for a required noise value, by attaching an "acoustic wedge" sound-absorbing material to the chamber's inner wall surface.The chamber enables measurement of sound characteristics such as volume, strength, and direction of noise issued from the equipment to be tested with environmental temperature(humidity) control performed by the air conditioner installed with a noise suppressor.
Satake provides comfort level measurement devices(housing environment test units), comprised of a model house and an external environment chamber for performing comprehensive air conditioner testing.By using a housing environment test device, it is possible to calculate the PMV(predicted mean vote) and PPD(predicted percentage of dissatisfied) comfort indicator values, to obtain the air flow distribution curve from the traverse air velocity, and to determine the temperature distribution curve from multiple thermoelectric measurements.The external environment simulator can simulatevarious atmospheric phenomena, such as sunshine, rain, wind and snow, enabling air conditioners to be tested under a variety of complex environmental conditions.
