2. Features of Product
Gree JKF Series Air-cooled Closed Control Unit is specially designed for the room where
communication equipment, computer, and precise instruments are placed. Applying
components with high performance, wide and touchable screen, advanced system design as
well as powerful control logic, the unit can efficiently control ambient humidity and keep stable
and long-term operation. The unit has been thoroughly tested with high standard and has been
under strict production control. All units have reserved remote monitoring function. Cooling
capacity of a single unit is between 5kW～40kW and can be expanded by combination of
modules.
◆Powerful control function
Touchable screen control: with 5.6’ touch screen to achieve easy, swift and convenient
control and operation.
All-sided monitoring: inspect the operation of the unit in all sides, including ambient temp
and humidity, temperature of evaporator, status of each component of the unit. (such as indoor
or outdoor fan, compressor, electric heater, etc), voltage, current, etc)
Multi functions display: use value, phrases, and curves to display data regarding operation
of the unit or environmental phenomenon.
Human-friendly control: each parameter or warning can be set according to the demand of
user. If malfunction occurs, the unit will give warning and, at the same time, it will keep running
or stop, which is selected according to the type of the malfunction.
Operation without watch: the unit can automatically operate according to set time of
starting or turning off. If the unit stops due to power failure, the unit will automatically operate at
previous status after power recovery. The operation of the unit can be remotely monitored and
at any time, the unit can be set from long distance.
◆High performance and high reliability
High performance: using brandname scroll compressor, female screw thread copper pipe,
Hyrophilic film aluminum fin, condensate fan with stepless regulation, the unit can reach high
efficiency and be energy-saving.
High reliability: All components are brandname products and be inspected by IQC of Gree.
The unit is strictly tested and can stably operate for long-term.
Operation under ultra low temperature: the unit can reliably operate even though outdoor
temperature is -35℃. The room temperature and humidity can be stable under all kinds of
rough conditions.
High sensible heat: it is designed for work condition with high sensible heat and can reduce
repeated humidifying as well as avoid condensate.
Huge air volume: use high efficient centrifugal fan which produces huge circulated air
volume to rapidly make temperature and humidity in the room even and clear local heat
generation.
ТОО "Everest climate", Р. К., г.Алматы | Телефон: [phone] | www.aircon.kz, e-mail: [email protected]

Rapid dry: the evaporator has two-stage. In dry mode, by reducing heat exchange area of
evaporator and evaporating temperature, the unit can rapidly dry and precisely control ambient
temperature and humidity.
◆Modular Design
High Precision: High precision: each module can be individually controlled. The cooling
capacity can also be individually controlled to flexibly adapt to environment and decrease
fluctuation of temperature and humidity.
Alternate operation: According to accumulated operation time, the unit which has less
operation time will start operation firstly while the unit which has more operation time will stop
firstly. Each module can alternately operate and be evenly controlled. If any module has
malfunction, others will automatically operate.
Convenient expanding of capacity: max. 253 master modules can be connected so the
problem of increasing heat load of the room can be flexibly handled and cost of further capacity
expanding by customer can be reduced.
Flexible installation: Single module can be casually installed according to layout of the
room, which makes the humidity and temperature of the room more even.
Convenient transportation: the single module is separately packaged so transportation and
installation are more convenient.
◆Structure Features
Separate electric control: electric control cabinet is totally separate with cold air circulation
system so there is no incipient fault caused by condensate and short circuit.
Convenient disassembly: main front panelAssy is fixed by clasp so the disassembly is very
convenient and the appearance is also nice.
High efficient filtering: There is G4 grade wide air filter in air return inlet of indoor unit to
guarantee cleanness and reduce loss of air pressure.
Snow-proof design: for outdoor unit, the air returned from the bottom and supplied from the
top to prevent the vent from being blocked by snow.
◆Multi products
Wide cooling range: GREE JKF series air-cooled closed control units include 5kW, 7kW,
13kW, 19kW, 25kW and 40kW units. And also, with combination of modules, customers can
easily select proper units according to their demand.
Various air outlet ways: Each kind of unit has three ways of air outlet, including free air
outlet (with cap), front air inlet and top air outlet (connecting to duct type), top air inlet and
bottom air outlet (air supplied from floor). Customers can freely select the units according to
specific conditions.

3.2 Description of the System
Structural features and system layout of JKF Series Air-cooled Closed Control Air
Conditioner are illustrated as above.
By compressor used for cooling and dehumidifying, electric heater for heating and
temperature adjustment, electrode humidifier for humidifying and logical program to control the
even running of every functional part, the unit adjusts the ambient temperature and humidity so
that it can meet the requirement of maintaining the precise temperature and humidity.
When the unit is running, the flowchart of refrigerant system is as below :

Notes:
1. This unit was designed, manufactured and tested according to National Standard GB/T
19413-2010.
2. Ambient temperature when testing cooling capacity：dry-bulb temperature indoors is
24℃and wet-bulb temperature is 17℃; dry-bulb temperature of outdoor side: 35℃.
3. The noise value was tested in the semi-anechoic chamber but the actual value will be a
little higher for the change of ambient temperature.
4. Refer to nameplate on the unit for parameters of the unit. And the unit is Subject to
change without further notice.
5. The temperature range of running environment is between：-35℃～48℃。
6.All models above can realize modular operation.
7. If there is any special requirement, please contact us.
5. Rformance correctlon
5.1 Correction of Cooling Capacity
Under different indoor or outdoor ambient temperatures, the cooling capacity of the unit will
be different. The below diagram can be reference when customer select models.
