Ÿ As a rule, heat pumps should be installed outdoors. However by varying the design of
air intake and outlet ducts, the heat pump can be used to condition cold air in the
room.
Ÿ It is recommended to install the unit by only air outlet with duct (Scheme 2 ) in
summer that could charge fresh cold air into room. ( The heat pump is installed
outdoor ).
Ÿ Scheme 3 is preferable in winter where there is other heat source in the room. ( The
heat pump is installed outdoor ).
