Abstract (en)

[origin: EP1923641A2] 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).
