Cycle function parts
8-3. A description of cycle function parts
No Cycle parts Functions
1
DVI compressor
(Digital Vapor Injection)
DVI compressor coupled with vapor injection controls the capacity 10 to 100% of its
capacity.
It enhances cooling and heating performance and COP with using vapor injection.
2
FVI compressor
(Fixed Vapor Injection)
FVI compressor coupled with vapor injection is fixed compressor. It enhances cooling,
heating performance and COP with using vapor injection.
3 PWM valve
|t is used for variation of digital compressor’s capacity. When the valve is open, the DVI
compressor keeps the unloading state, otherwise loading state.
4 Discharge temp. sensor
It measures the temperature of compressor outlet. The main function of it is to protect
compressor from overheating.
5 Oil separator
It separates oil and refrigerant discharged from the compressor and returns the oil into
compressor again.
6 High pressure switch It protects the system from abnormal high pressure. (Open : 4.1Mpa, Close : 3.5 Mpa)
7 Hot gas bypass valve
When the suction pressure becomes abnormal low pressure, it opens.
During the oil balance operation, it makes high pressure for the shell of compressor
8 High pressure sensor
The main function of it controls the capacity of compressor in pursuit of target of high
pressure in heating operation by measuring the value of the system.
9 4way valve It enables to change operating mode into cooling and heating mode.
10 Ambient air temp. sensor It measures the temperature of ambient.
11 Cond_out temp. sensor It has application to know subcooling and the complete point of defrost.
12 Main EEV 1, 2
It controls the amount of refrigerant entering outdoor’s heat exchanger in heating
operation.
13 Liquid bypass valve When the compressor is overheating, it opens to make discharge temperature low.
14 EVI EEV
It enables to secure sufficient subcooling and control the amount of vapor entering into
vapor port of compressor.
15 Turbo intercooler
Through turbo intercooler, heat is exchanged each other between saturated liquid
refrigerant and a little expanded refrigerant.
16 EVI_in temp. sensor
These temperature sensors enable to control EVI EEV’s step to secure superheat.
17 EVI_out temp. sensor
18 Liquid tube temp. sensor
It is used to know subcooling.
(Subcooling = The saturated temp. of high pressure - Liquid tube temp.)
19 EVI bypass valve This valve closes during application of vapor injection.
20 Suction temp. sensor This is applied to know superheat in heating mode with the low pressure sensor.
21 Accumulator Ambient air temperature sensor (Tair)
22 Oil valve When oil balance operation happens, this valve opens.
23 Low pressure sensor
The main function of it is to control the capacity of compressor in pursuit of target of low
pressure in cooling operation by measuring the low pressure.
24 Sump(Base) temp. sensor
With checking sump temperature of compressor, it prevents the compressor from liquid
back and overheating.
25 Oil temp. sensor While the oil balance is operating, it make a self-diagnosis of the oil valve.
26 Outdoor EEV valve
In order to prevent outdoor heat exchanger from refrigerant accumulation in main cooling
operation, this valve closes, otherwise Main EEV controls the amount of refrigerant.

The installation space mentioned above is minimum suggested clearance.
To secure enough service space and performance of system, take account of more sufficient space.
The required minimum space between outdoor units for service and performance of system is at least
100mm(4in).

Space requirements
2-3. Installing duct for horizontal exhaust discharge
It is necessary to install an air-discharge duct (field supply) to direct exhaust from the fan horizontally if it is difficult to provide a
minimum space of 2m(6.6 ft) between the air-discharge duct outlet and a nearby obstacle.
2-4. Installing the outdoor unit in harsh environments
In abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to guard against excessive wind
and snow should be taken to ensure the unit's correct operation. Snow-proof duct (field supply) should be fitted to the unit and
direct exposure to the wind should be avoided as much as possible. When the unit is expected to operate in cooling mode in
condition under 10°C(50°F), in snowy areas, in environments subject to strong winds or rain, install air inlet and outlet ducting as
shown in the below example
Discharged air
Louver
Suction air
Upper floor
Discharged air
Ex) Balcony
Ex) Mechanical room
The frame/foundation should be higher than expected snowfall.
The foundation must be solid and the unit must be secured with anchor bolts.
Be sure to install unit in a place strong enough to withstand its weight.
When installing on a roof subject to strong wind, countermeasures must be taken to prevent the unit form being
overturned.
Any lack of strength may cause unit to fall down, resulting in a personal injury.
For more detailed information about installation, refer to installation manual.

Cautions Correct piping work Wrong piping work
The refrigerant piping
should be the same level or
lower than connecting
position of piping to
outdoor units.
Piping work should be run
with side direction for
better uniform distribution
of refrigarant and oil like
next diagram.
Outdoor joint kits should
be installed in a horizontal
direction, even it is a low
pressure pipe.
When the piping length
between outdoor and
branch joints is 2m(6.6 ft)
or more, a vertical trap has
to be installed like right
diagram.
