Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
Heat-pump air conditioners heat your entire
room by recirculating air throughout the room,
with the result that some time may be required
after first starting the air conditioner until the
room is heated.
room by recirculating air throughout the room,
with the result that some time may be required
after first starting the air conditioner until the
room is heated.
This air conditioner operates on the heat-pump
principle, absorbing heat from outdoor air and
transferring that heat indoors. As a result, the
operating performance is reduced as outdoor air
temperature drops. If you feel that insufficient
heating perfomance is being produced, we
recommend you use this air conditioner in
conjunction with another kind of heating
appliance.
