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 simulate various atmospheric phenomena, such as sunshine, rain, wind and snow, enabling air conditioners to be tested under a variety of complex environmental conditions.
