*1 90m [295ft] is available. When the piping length exceeds 40m [131ft], use one size larger liquid pipe starting
with the section of piping where 40m [131ft] is exceeded and all piping after that point.
*2 90m [295ft] is available depending on the model and installation conditions. For more detailed information, contact your local distributor.
*3 60m [196ft] is available depending on the model and installation conditions. For more detailed information, contact your local distributor.
*4 30m [98ft] is available. If the height difference between indoor units exceeds 15m [49ft] (but does not exceed 30m [98ft] ), use one size larger pipes for indoor unit liquid pipes.

changeover from cooling to heating, ensuring that a constant indoor climate is maintained in all zones. The compact
outdoor unit utilizes an inverter-driven compressor for effective energy use.
With a wide lineup of indoor units connected to a flexible piping system, the CITY MULTI Series can be configured to suit
diverse applications. Up to 50 (Y-Series) indoor units can be connected with up to 130% connected capacity to maximize
engineering design options. This feature allows easy air conditioning in each area with convenient individual controllers.

The world’s first* two-pipe system that
simultaneously cools and heats
The CITY MULTI R2-Series offers the ultimate in freedom and flexibility. Cool one zone while heating another. Our
exclusive BC controller makes two-pipe simultaneous cooling and heating possible. It is the technological heart of the
CITY MULTI R2-Series. It houses a liquid and gas separator, allowing the outdoor unit to deliver a mixture of hot gas for
heating and liquid for cooling, all through the same pipe.
This innovation results in virtually no energy wasted by being expelled outdoors. Depending on capacity, up to 50 indoor
units can be connected with up to 150% connected capacity.

Compared to previous models, all the single modules (Y-series) in YNW-Series have improved EER and COP. For
example, EER of the 14HP model (PUHY-EP350YNW-A1) is higher by about 12%. All these models ensure high
energy saving.

*In the low noise mode, the capacity will reduce.
Energy Saving
The low-noise mode, which conventionally only had one pattern, has been increased to four patterns. Including the
rated pattern, a mode can be selected from a total of five patterns. The low-noise mode has four patterns (85%,
70%, 60% and 50%) in respect to the fan speed. This can be set with the outdoor unit’s dip switch. The pattern can
be selected according to the customer’s requests when low-noise operation is required.

supported with no extra-cost options.
This increases design flexibility and facilitates
installation of these units even in high-rise
buildings.

The concave-shaped blade of the propeller fan enables air to flow along the outer circumference of the blade while reducing a
disturbance of air flow that occurs in the upstream and downstream of conventional propeller fans. This helps reduce power
consumption as well as minimises sound levels.
Furthermore, the change of the orientation of the fan blade from the outer circumference direction to the inner circumference
direction reduces air leakage from the outer circumference and sends more air to the upstream of the fan.

The compressor, known as the heart of the air conditioner, has been improved. A centrifugal force canceling mechanism and
a multi-port mechanism have been developed. In addition, we have mounted a high-efficiency motor. The synergetic effect of
these latest technologies increases the compressor performance and efficiency, and also helps to improve the performance
of the outdoor unit.
The structure of the scroll compressor causes a centrifugal force during operation. Conventionally, that centrifugal force is applied onto the scroll section.
This causes refrigerant to leak, and restricts the increase in rotational speed to a maximum of 120rps.
With the latest compressor, the latest structure (centrifugal force canceling mechanism) has been mounted to suppress the centrifugal force. This mecha-
nism successfully suppresses the centrifugal force generated at the scroll section, reduces refrigerant leakage losses, and increases the compressor
efficiency. The maximum rotational speed has been increased from the conventional 120rps to 140rps.
This mechanism also speeds up the start of operation, and enables operations such as preheat defrost operation and the smooth auto-shift startup mode.

Centrifugal force canceling mechanism (8 to 14HP)
The insulator section that traditionally created a
dead space is eliminated by insulating the motor’s
stator film. Since winding can be set in that
section, the winding area can be increased by
approx. 9%. The wire diameter has also been
increased by two ranks, so the resistance between
terminals is reduced, and the insulation distance
is shorter. This improves the motor’s operation
performance and contributes to high-efficiency
operation of the compressor.

The sub-port is opened during partial load
operation to discharge the over-compressed gas.
Multi-port
When the target discharge pressure is
reached, the multiport opens, and the gas
refrigerant is discharged. This reduces drive
losses caused by over-compression.
Conventional model
Conventionally, gas refrigerant is compressed
to a set pressure, and then lowered to the
target discharge pressure at which it is
discharged. This causes drive losses from
over-compression.
The motor can be wound in the section where the
insulator was, and a larger wire diameter can be used.
The insulator section is large, and the
area where the copper wire can be wound
is small.

Efficient partial load operation is realised by avoiding over-
compression. With the scroll compressor, the distance of
the compression process in the scroll is usually fixed, so
over-compression occurs during low loads and low rotation.
The latest compressor is equipped with two sub-ports in
addition to the conventional discharge port to reduce this
over-compression loss during low loads. In operating
conditions with a low compression rate, the distance in the
compression process is kept short by successfully avoiding
unnecessary compression, and contributing to efficient
partial load operation.

Centrifugal force canceling mechanism (8 to 14HP)
The insulator section that traditionally created a
dead space is eliminated by insulating the motor’s
stator film. Since winding can be set in that
section, the winding area can be increased by
approx. 9%. The wire diameter has also been
increased by two ranks, so the resistance between
terminals is reduced, and the insulation distance
is shorter. This improves the motor’s operation
performance and contributes to high-efficiency
operation of the compressor.

The sub-port is opened during partial load
operation to discharge the over-compressed gas.
Multi-port
When the target discharge pressure is
reached, the multiport opens, and the gas
refrigerant is discharged. This reduces drive
losses caused by over-compression.
Conventional model
Conventionally, gas refrigerant is compressed
to a set pressure, and then lowered to the
target discharge pressure at which it is
discharged. This causes drive losses from
over-compression.
The motor can be wound in the section where the
insulator was, and a larger wire diameter can be used.
The insulator section is large, and the
area where the copper wire can be wound
is small.

Efficient partial load operation is realised by avoiding over-
compression. With the scroll compressor, the distance of
the compression process in the scroll is usually fixed, so
over-compression occurs during low loads and low rotation.
The latest compressor is equipped with two sub-ports in
addition to the conventional discharge port to reduce this
over-compression loss during low loads. In operating
conditions with a low compression rate, the distance in the
compression process is kept short by successfully avoiding
unnecessary compression, and contributing to efficient
partial load operation.
