■ Working conditions for nominal cooling capacity test: water flow
rate 0.172m3/(h.kw); temperature of outlet water 7°C;
outdoor ambient temperature 35°C.
■ Working conditions for nominal heating capacity test: water flow
rate 0.172m3/(h.kw); temperature of outlet water 45°C;
temperature of outdoor dry/wet bulb 7°C/6°C.
■ The sound level is tested before the unit leaves factory.
Practically, due to environment noise and other factors, the sound
level tested might
be different from those listed in the above table.
■ Please refer to the User Manual for specific operation ranges.
1. Units of this series feature a classic European air conditioner
design (chilled water/heat pump + indoor terminals) for precise
temperature control. The units can provide you with a comfortable,
healthy and graceful working/living environment. The uni ts feature
a heat sink mechanism using circulatory air and needs no cooling
tower. This not only saves the cost of the cooling tower, but also
saves precious building space. Units of this series feature various
models and dimensions to meet different installation requirements.
2. Units of this series are equipped with fully hermetic
compressors which are stable, advanced and reliable. All components
have undergone strict integration and compatibility test to ensure
optimized performance and efficient/energy-saving operation all
year round. The EKAC120B integrated units perfectly unify the
parallel compressor technology and electronic throttle technology
to quickly modulate the cooling capacity to the set value, thereby
making sure that the units are most energy efficient. The EER is
even higher with partial workload. For example, for EKAC120B unit,
the EER is 6% higher with 75% of workload, 11% higher with 50% of
workload, and 16% higher with 25% of workload. The solenoid
interlock control function can shut down the master unit and water
pump automatically when all fans have stopped working, making the
unit more energy saving.
3. The EKAC120B integrated unit features a 500-step PMV electronic
expansion valve for precise PID flow control, dynamic and real-time
adjustment of the cooling capacity and accurate water temperature
control. An electronic expansion valve with a large flow modulation
range helps optimize the performance of various parts of the
system, and makes the system work reliably under any workload. The
units can automatically adapt to changing ambient temperatures,
completely eliminating cooling system vibration during the capacity
4. Long and strict tests prove the unit can work reliably in an
environment as hot as 48°C (cooling) or as cold as -10°C (heating).
With a smart split design, all water pipes can be installed indoor
to prevent freezing during cold winters. The units can work with
boilers to meet heating requirements in areas which are extremely
cold in winter. The units feature built-in high/low pressure
protection, cooling freezing protection, winter freezing
protection, compressor overload protection, water pressure-drop
switch etc. to maximize reliability. In case of any failure, the
micro-computer controller provides alarms using sound and
indicators on a real-time basis. Besides unconditional manual
defrosting, the controller also supports efficient auto defrosting
based on multiple parameters during heating operations.
5. The units feature a strengthened vibration isolation case and
multi-grade sound dampening. Thanks to a fully hermetic scroll
compressor and a low-rev high-efficiency heat-sink fan, the
operation sound and vibration of the units are brought down to an
industry leading level. With an innovative auto silence feature for
night time, the EKAC120B unit are more quiet at night.
6. The integrated series units feature top air supply, compact
design, low height, small footprint and a fashionable and elegant
7. The units are small and easy to move, and can be flexibly
installed on rooftops, balconies and other suitable outdoor places
to save precious building space. There is no need to design or
installed a cooling tower, boiler, cooling pump or relevant pipes.
All ten major accessories of the water system are self contained,
including horizontal multi-grade pump, plate heat exchanger, water
tank, hermetic expansion water tank, differential water pressure
switch, water filter, relief valve, auto air discharge valve, auto
water refill valve and sewage discharge valve. The whole central
air conditioner is very easy to install as you just need to connect
some water pipes. In addition, an optional 30Pa static pressure air
discharge through air ducts makes theEKAC120B integrated units more
flexible to install.
8. The units are equipped with a smart micro-computer control
system to provide various control functions, such as function
settings, parameter viewing, group control, etc. The controller has
three levels of password protection to provide convenient and
reliable operation management. Workload is automatically averaged
among compressors to improve the durability of the entire system.
Auto startup/shutdown can be configured for the central air
conditioner on a weekly basis. All-round safety features make sure
that the units are safe and reliable. With a terminal (indoor unit)
interlock control function, the master unit can start up
automatically as long as one terminal (indoor unit) is running.
EKAC small residential air-cooled cold/hot water units are a new
generation of residential air conditioners
manufactured for the Chinese market based on leadingedge European
design concepts to fit well with various graceful upholsteries.
Units of this series require no cooling tower or special equipment
room. All accessories of the water system are self contained and
can be connected to various indoor terminals through the master
unit. Equipped with a smart controller, units of this series can
bring you all the comfort that a residential central air
conditioner could possibly provide. EKAC small residential
air-cooled cold/hot water units feature various merits such as
smart control, high efficiency, low operation sound, flexible
structure, convenient operation, safe running and easy installation
and maintenance. Units of this series can be widely used in houses,
villas, stores, top-grade apartments, office buildings and other
commercial areas which require separate air conditioning.
