Presently considered to be arranged and in the open unit for the same

摘要

A presently contains a unit arranged in the open (6) with a heat exchanger (14), in which a refrigerant heat from outside air through passage of heat exchange with ambient air absorbs. A drainage trough (61) is provided on the second heat exchanger (14) developing condensed water. In the presently is a drainage line (63) to a drainage hole (62) of the drainage trough (61) and extends in the ground (72), so that a front end of the drainage line (63) in the constructional component (72) is embedded. Alternatively, a heater (5) for heating of the condensed water in the drainage line (63) is arranged. Accordingly, a freezing of the condensed water onto the surface of the ground (72) under which, in the free arranged unit (6) are avoided.
