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

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.
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 of the system. The unit can work reliably under any load and
automatically adapt to changing ambient temperatures, completely eliminating cooling system vibration.
Silent and Comfortable The entire unit features vibration isolation design and multiple noise reduction processes. Both noise level and vibration level of the unit take the lead in the industry thanks to its name-brand quite hermetic volute compressors and two-gear quiet fans. The noise level of the unit is significantly reduced using professional noise reduction practices, such as comparing, choosing and improving fans, motors, structures and pipelines based on noise spectrum analysis results. Innovative smart silencing mode can automatically adjust the fan rev (high/low) according to outdoor temperature and the operation status of the unit. This makes the unit even quieter in operation mode.
Smart Control and Simple Operation
The unit uses a micro-computer controller with a large LCD screen to facilitate operation. The master unit can be used to control slave units in a smart, simple, easy, and convenient way.
Flexible Installation, No Need for Equipment Room
The unit needs no additional equipment room, and can be mounted on the floor, building roof, etc. Modular design makes each unit small in dimension and suitable for transportation by cargo elevator, thus saving hoist cost during construction. The unit can also be installed step by step to shorten the construction period. Each unit has a separate refrigerant circuit. This reduces the probability of refrigerant leakage which could damage the ozonosphere.
