A breathing type storage housing is exposed night and day to fluxuating outdoor air temperature. The housing defines a substantially sealed container of air that is alternately warmed and cooled by heat transferred through the housing due to daytime solar warming and nighttime cooling of the housing. Pressure responsive valves connect the container to the outside of the housing and are operable in response to temperature and pressure fluxuations inside the container for exhalation of warmed air from the container and for inhalation of cooled air into the container from outside the housing. Cooling of the air inside the container is purposely retarded whereby the operation of the valve for connecting the container to the outside of the housing for inhalation is delayed until the outdoor air temperature has decreased sufficiently to condense water vapor out of the outside air.

Respiratory housing means subjected to natural warming and cooling of ambient air and water vapor; said housing means defining a substantially sealed volume containing an air and water vapor mixture that is warmed by ambient air and expanded during daytime and cooled by ambient air and contracted during nighttime in response to heat transfer through said housing means; pressure responsive outlet and inlet valve means connecting said volume with ambient air and water vapor; said outlet valve being operable in response to warming and expansion of said mixture to exhale the same from said volume; said inlet valve being operable in response to cooling and contraction of said mixture to inhale ambient air and water vapor into said volume; and, means for delaying operation of said inlet valve until ambient water vapor is condensed by natural cooling.
