|Description|| ||You can select an external electric heater box according to the
required heating capacity. For specifications|
of external electric heater boxes, see P22.
■ The rated cooling capacity is measured in the following
condition: The indoor air dry bulb reads 27°C, the wet bulb reads
19°C, and the
outdoor dry bulb reads 35°C. The condition for the rated heating
capacity is as follows: The indoor air dry bulb reads 20°C, the
bulb reads 7°C, and the wet bulb reads 6°C. The cooling capacity
and heating capacity change according to the conditions. During
selection, you need to select a proper model based on local
■ External static pressure indicates the static pressure under the
nominal air flow. The static pressure may change depending on
requirements. For the specific value, see the reading on the
■ The unit input power and current are based on the standard
external static pressure. If the customer requires a different
pressure, check the nameplate on the unit for the power and current
■ The specifications may suffer change due to product update. The
readings on the nameplate of the unit prevail.
■ The preceding data is based on the condition that the connection
pipe between indoor and outdoor units is 7.5m.
■ For details about on-site power distribution and wiring for unit
installation, see the nameplate or installation manual of the unit.
■ No refrigerant is filled into any unit upon factory delivery.
1, Outstanding fans, motors and other components specially designed
for air conditioners ensure that the unit operates smoothly.
2, Brand-new dustproof and rustproof painting makes sure that the
outdoor unit looks new after many years of operation.
3, The outdoor unit adopts modular design and stepped startup,
efficiently reducing shock on the grid.
4, Multiple levels of cooling are provided, allowing differential
energy regulation under different load conditions and reducing the
5, The compressors support even wear, prolonging the lifecycle
6, Featuring a high static pressure design, the indoor unit can
supply conditioned air over a long distance, enabling customers to
select the installation site as required. To service any component
of the unit, you only need to remove several screws on either side
of the unit.
7, The connection pipe between indoor and outdoor units reaches up
to 50 m, and the height difference can reach 20 m.
8, The outdoor unit adopts top air supply, allowing combined
installation of multiple outdoor units for pleasant appearance.
9, The indoor unit features an efficient and low-noise centrifugal
fan as well as sound-absorbing and thermal insulation inner walls
to ensure silent operation.
10, The indoor unit can be mounted on a far-away ceiling to make
the conditioned room more silent.
11, Unique insulation design for compressors ensures an outstanding
12, The outdoor unit uses new spiral fans, which have smooth an air
suction structure, greatly reduce turbulent flows, and lower the
air flow noise.
13, The smart microcomputer controller supports four operation
modes: cooling, heating, fan, and auto control. It also provides
timed ON/OFF, auto-defrosting, and fault display functions.
14, The unit uses a brand efficient volute compressor, which
consumes less electricity while providing the same cooling/ heating
capacity. The compressor features a small volume and stable
running. The unit uses advanced thermal expansion valve control
technology to accurately control tributary flows.
15, During operation, if the power fails, the unit can
automatically start once the power resumes no matter how long the
power failure lasts. After starting from an exceptional power
failure, the unit automatically resumes the running status before
the power failure. This function is not enabled upon factory
delivery. It needs to be set through DIP switches on site.
16, The unit has strong adaptability to the environment. It can
normally perform cooling when the outdoor temperature is between
18°C and 48°C. It can normally perform heating when the outdoor
temperature is between -10°C and 27°C.
17, The outdoor unit of the low-temperature cooling unit uses a
brushless DC motor to control the rotation speed of the condensing
fan, efficiently expanding the operating range of the unit and
allowing it to normally perform cooling when the outdoor ambient
temperature is between -10°C and 48°C.
18, Multiple types of units with electric heater boxes or hot water
coil boxes are available.
19, The outdoor unit produces a low noise. The system is optimized
to suppress vibration and noise during operation, achieving quiet
and stable unit running.
20, The unit normally runs within ±10% of the rated voltage
21,The shell of the outdoor unit is sprayed with anti-UV and pure
polyester mineral highlighter on dual sides, effectively prolonging
the lifecycle of the unit.
The EKDB high static pressure duct type air conditioning unit meets
customer requirements for product efficiency, performance, safety,
and intelligence. Flexible combination and intelligent control
