Layout-free Refrigererant Piping
The branch type piping makes the system flexible enough to satisfy
any layout plan on the floor or in a room.
Rapid Temperature Response and High Stability
An intake temperature sensor automatically controls both the existing and
set temperature based on a "fuzzy logic". With a speed of response and
stability previously not possible, the system powerfully performs to
provide you with a high level of comfort.
*E.E.V.pulse keeps the unit operating at the optimim condition. The system uses an
electronic expansion valve in indoor units to control the flow rate of refrigerant according
to the load.

MHI's High Technology Achieves a
Quietness for Both People and the
Environment
Large diameter fan developed by MHI operates efficiently. Very little
resistance to air flow assures extremely quiet operation. Even
at low speed,

is only 34dB.
Eliminating Thermal Unevenness with
ON-OFF Control
An air-conditioned temperature tends to be uneven when the air-
conditioning system is simply controlled on or off. This problem has
remained unsolved until today. Now, MHI's new temperature sensor
eliminates this problem by swifty checking for any thermal
unevenness. Other effects of an indoor unit on-off operations are also
suppressed to the minimum level possible. Thus, the system conditions
the air and maintains the room temperature at a comfortable, constant
level. A sophisticated design for sophisticated users.
