Fig. 4 is a vertical sectional view showing a specific example, Fig. 5 is a block diagram showing an example in which an outside air cooling means and a conventional forced cooling means are incorporated into one device, and Fig. 6 is a block diagram of the same. A vertical cross-sectional view showing a specific example, Figure 7 is a diagram showing the relationship between the detected temperature and the opening/closing of the damper for introducing outside air and the damper for introducing indoor air, and Figure 8 is a diagram showing the relationship between the detected temperature and the opening and closing of the damper for introducing outside air and the damper for introducing indoor air. It is a figure which illustrates the specific structure which controls a damper and the damper for indoor air introduction. In the figure, Q is a heat load such as a computer, C is a mixing chamber, DoA is a damper for adjusting the intake outside air amount, DRA is a damper for adjusting the indoor return air intake amount, F is a blower,
S, S, ~S3 are temperature detectors, 3 is air filters, 7
is a cooler, and 8 is a heating device.

Claims

[Scope of utility model registration request]

In a device that cools a room by introducing outside air into the room when the outside air temperature is lower than the indoor temperature, there is a mixing chamber that introduces and mixes outside air and indoor return air, and the amount of outside air introduced into the mixing chamber. means for adjusting the amount of indoor return air introduced into the mixing chamber; a blower for guiding the air mixed in the mixing chamber to the heat load; An outside air cooling device comprising means for detecting a change in air temperature and controlling drive sources for the outside air amount adjusting means and the indoor return air amount adjusting means.
