Ultra High-Efficiency Screw-Type Air-Cooled Chilled Water (Heat Pump) Unit R134a Refrigerant
Overview
Over half a century of innovation and development, EK air conditioning air-cooled heat-pump technology has become the leading technology in the global industry. EKAS screwtype air-cooled chilled water (heat pump) unit originates from the air-cooling kingdom, Italy, and inherits the Europeleading large-scale air-cooled unit design achievements, and adopts the new-generation R134a special screw technology. The unit optimizes system configuration and delivers stable and reliable performance, providing the highest energy efficiency (EER3.48) in the industry.
Features
1. Patent dual screw compressor delivering high efficiency at low noise
The latest generation HFC-134a dedicated dual-screw compressors developed by EK Italy are adopted, and brand new gap and oil injection design is used to fully improve full-load and load-drop running efficiency. The patent slider design helps improve the running efficiency at partial load by up to 15%. The unit has passed various certification tests such as EU security regulation certification CE mark, EU pressure container certification PED, US lab national certification UL, and CRAA certification, and provides guaranteed long-term high-efficiency safe and reliable running.
2.High-efficiency heat exchanger with outstanding performance
■ The heat exchanger for EKAS screw-type air-cooled chilled water
(heat pump) unit adopts patent refrigerant distribution design and
passes strict certification of EU and US ASME.
The internal heat exchange pipe uses high-efficiency internal
threaded heat exchange copper tube to strengthen thermal conduction
at the water side and refrigerant side, maximizing thermal
conduction efficiency, reducing energy consumption of the unit, and
reducing customer running expenses.
■ The standard piping mode provided by the heat exchanger is trough
coupling connection (with short tube), facilitating field
installation. Each evaporator and condenser is equipped with
independent air exhaust and water drainage devices.
■ The heat exchanger facilitates compressor oil return design for
simple oil return without an oil pump, eliminating the risks of a
frozen heat exchange pipe. The heat exchanger requires a
refrigerant filling amount that is only 1/3 compared with an
ordinary heat exchanger, and does not leak, making it
environment-friendly and reliable.
3.New economizer
The unit adopts a brand new economizer circulation design.
The electronic expansion valve implements precision
control,increasing the over-cooling degree of the unit, and greatly
improving the cooling capacity and cooling efficiency of the unit.
4.Stable and precise control through electronic expansion valves
The full series units adopt electronic expansion valve control
technology with independent power supply. The design of dual power
supply implements optimal control for superheating and ensures
high-performance running of the unit. The precise PID flow control
through electronic expansion valves
allows stable refrigerant control, protects the compressors, and
monitors air exhausted by compressors, avoiding faults of
compressors.
5.Patent aerofoil screw fan providing large air flow and low noise
■ The unit fan adopts aerofoil low-noise fan design to
control air interference, produce a large air flow, and efficiently
reduce the fan noise.
■ Optimized bent impeller front-end design suppressesair eddy at
the edge of the fan impellers, improves the rotation efficiency,
and reduces the noise.
■ Idle running of the motor is eliminated, and overheat protection
is implemented, prolonging the lifecycle.
■ It is directly driven by the motor, which eliminates transmission
loss and reduces vibration.
■ A high-static-pressure fan motor is optional, meeting
requirements of various scenarios for static pressure.
6. Environment-friendly
■ The environment-friendly R134a refrigerant delivers outstanding
performance, saves electricity, contains no chlorine, does no harm
to the atmospheric ozone layer, and therefore has an unrestricted
term of use.
■ The emission of CO2 is efficiently reduced, alleviating the
increasingly severe urban heat island effect and enabling green
buildings .
7.Wide running range and long lifecycle
■ The shell of the unit adopts electro-galvanized sheet and is
electrostatic sprayed with anti-erosive coating, which effectively
prevents rust and adapts to various harsh outdoor conditions.
■ The unit adapts to a wide atmospheric temperature range from -10
ºC to 50 ºC.
■ Efficient automatic precise defrosting is implemented, prolonging
the lifecycle of the unit.
■ The unit directly exchanges heat with the atmosphere, producing
no pollution
8. Centralized Control
EK centralized control system adopts the industry-leading control
solution. The product configuration is applicable to the chilled
pump control system solution. Multiple persons are allowed to
control and monitor the unit on the homepage of a Microsoft-based
web browser.
The international general RS485 standard serial communication
interface is adopted. Joint connection with other building access
systems (BASs) is supported through the communication protocol
conversion module (optional) provided by EK to implement group
control on multiple units. The standard protocols include BacNet,
Modbus, and Lonwork.
