<p>A convection space heater/cooler has a front panel separated by a gap from a rear panel through which air passes driven by a fan and air baffles. During low-temperature operation the lower and upright sides are closed, as is most of the upper side. The residual opening in the upper side discharges cool air. The gap further has a number of baffle plates separating the heated panels and convection panels. In the cooling mode cold water is introduced via the hot panel return pipe.</p> |
