(57) An air-conditioning apparatus includes upper and lower chambers (21, 22), and first
and second heat exchange units (3, 4) respectively disposed in the upper and lower
chambers (21, 22) and respectively having first and second working fluids (30, 40).
The first heat exchange unit (3) has a condenser (31) and a first fan (32) adapted
to draw air into the upper chamber (21) for exchange of heat with the condenser (31)
. The second heat exchange unit (4) has an evaporator (41) and a second fan (42) adapted
to draw air into the lower chamber (22) for exchange of heat with the evaporator (41).
First and second tubing units (6, 7) are respectively connected to the condenser (31)
and the evaporator (41) and each has a heat exchange tube section (61, 71). The heat
exchange tube sections (61, 71) of the first and tubing units (6, 7) are associated
with each other such that the second working fluid (40) transfers heat to the first
working fluid (30).
