8 tons Total Heat Recovery Air-cooled Heat Pump Unit with max dosmesitc hot water temperature 60 C

Unit Features

Air-cooled heat pump units of the full heat recovery model feature a brand new European design and R&D technology. They are a perfect combination of air-cooled chilled/hot water unit and air source heat pump hot water unit. Besides providing cooling in summer and heating in winter for buildings, units of this series can also provide hot water of 45°C - 60°C. Therefore, they can completely replace boilers and save customers a sum of investment. This is not only cost effective but also environment friendly. In addition, absorbing heat discharged by air conditioners can also avoid "urban heat island effect".

0.172 m3/(h·kw); outdoor dry/web bulb temperature 7°C/6°C.
2. Cooling + Hot WaterTest conditions for nominal capacity: Hot water side: Outlet water temp. 45°C; nominal water flow for
hot water mode.
Air conditioning side: Outlet water temp. 7°C; nominal water
flow for heating mode.
3. Hot water mode: Test conditions for nominal water flow: Temp. of outdoor dry/wet bulb: 20°C/15°C; temp. of inlet/outlet
water: 50°C/55°C.
4. Water resistance includes water pressure drop of the unit and the attached Y-shaped filter; Water resistance at the hot
water side includes water pressure drop of the unit and does not include the pressure drop at the Y-shaped filter and
other components.
5. Total heat recovery units can be combined with units of the same model or different models. A maximum of 16 units can
be combined to form an array.

Providing Free Hot Water and Saving Investment

In addition to air conditioning, the total heat recovery air-cooled heat pump unit also works as a boiler to
recycle condensate heat and provide hot water at 45°C - 60°C free of charge. This saves investment and
installation space for a boiler.

Efficient, Environment-Friendly, Energy-Saving, and Leading Edge Design, Saving up to 60% of Energy

Based on its leading-edge design for air-cooled and heat pump units in Europe as well as the wide use of
its air-cooled heat pump units in China, EK has launched this series of innovative modular total heat
recovery air-cooled heat pump units. Compared with common modular air-cooled heat pump units +
boilers, units of this series saves energy by as mush as 60%.

Comfortable and Cost Effective

By running a total heat recovery unit in the cooling + hot water mode, a customer can enjoy comfortable air conditioning as well as free hot water, especially during transitional seasons. This makes the unit energy saving and environment friendly.

Reliable Operation

The unit has undergone strict and long-duration tests according to the most stringent standards, and can
work reliably to providing cooling when the ambient temperature is as high as 48°C and heating when the
ambient temperature is as low as -20°C.The system features built-in high/low pressure protection, cooling freezing protection, winter freezing protection, compressor overload protection and water pressure-drop switch etc. to maximize the safety of the unit. In case of any failure, the controller provides alarms on a real-time basis.

Precise Water Temperature Control

The unit uses a 500-step PMV electronic expansion valve for precise PID control, dynamic and real-time
adjustment of the system, and higher-precision water temperature control. This helps optimize the
performance of each and every part
