(57) Equipment for cooling and heating spaces in buildings, in whose housing (14), furnished
with an entry for the intake of circulating air and an exhaust for conditioned air,
there is a heat exchanger (1) unit with fan (4), where that fan (4) is positioned
on the outlet side of the heat exchanger (1), whilst under the heat transfer surface
of the heat exchanger (1) there is a condensate tank (2). The heat transfer surface
of the heat exchanger (1) is tightly closed at both ends by the housing (14), which
is furnished with a tightly fitting service lid (7). The heat transfer surface of
the heat exchanger (1) consists of a cylindrical annular segment with axis perpendicular
to the direction of the horizontal flow of the incoming circulating air, and the unclosed
part of the cylinder fits tightly for its whole height against the vertical closing
wall of the housing (14). Inside that cylindrical heat transfer surface there is a
suction fan (4) whose exhaust passes sealingly through the vertical closing wall of
the housing (14) in the location of the unclosed part of the cylinder of the heat
transfer surface of the heat exchanger (1), and is connected by a distribution duct
(9), through a diffuser (8), to an air distribution element (10).
