■ Air conditioning mode: Test conditions for nominal cooling capacity: outlet water temperature 7°C; water flow: 0.172 m3/(h·kW); outdoor ambient temperature
35°C. Test conditions for nominal heating capacity: outlet water temperature: 45°C; water flow: 0.172 m3/(h·kW); temperature of outdoor dry/wet bulb: 7°C/6°C.
■ Cooling + Heat recovery mode Test conditions for nominal cooling capacity: Hot water side: temperature of outlet water 45°C, water flow 0.215 m3/(h·kW); Air
conditioning side: temperature of outlet water 7°C, water flow 0.172 m3/(h·kW);
■ Hot water mode: Test conditions for nominal water flow: Ambient temp: 20/15°C; outlet water temp: 45°C; water flow of cooling + heat recovery mode.
■ Water resistance at the air conditioner side 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
■ Pipes outside the unit need to be customized and installed on site. The diameter of the pipes must meet design requirements. EK does not provide the pipes.
■ Full heat recovery units and other units can be combined to form partial heat recovery modular system. Full heat recovery units can also be combined to form a
total heat recovery system. Modular units can be formed using the 1~16 basic modules. The above table lists the parameters for common module combinations.
■ For on-site electric wiring, see the name plate or installation menu of the unit.
Total heat recovery Air-cooled chiller/heat pump 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 around-the-clock hot water of 40°C -55°C no matter in what climate. 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 modular total heat recovery air-cooled chiller/heat pump also works as a boiler to recycle waste heat and provide hot water at 40°C - 55°C free of charge. This saves investment and installation space for a boiler.
Industry-Leading Hybrid Connection Technology
As an industry pioneer, EK launched units that support hybrid modular connection with common air cooled heat pump units. Total heat recovery units can be networked with standard modular units to form a partial heat recovery modular system, and can also be networked with total heat recovery units to form a Total heat recovery system to meet different heat recovery requirements.
Efficient and Environment Friendly,Saving More Than 60% of Energy
The unit recycles waste heat generated during condensation to improve the COP up to 8.32, saving more than 60% of energy compared with common modular units.Recycling heat is also environment friendly, and helps to avoid the "Heat Island Effect".
Comfortable and Cost Effective
By running a total heat recovery modular 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.
Units of this series are widely used in places where hot water is required, such as hotels, hospitals, schools, villas and bathing centers.
Five running modes for choosing
When cooling is required but hot water is not required, a customer can choose the cooling mode.In this case, the unit works in cooling only mode, the same as a common air-cooled heat pump unit.
When heating is required but hot water is not required, a customer can choose the heating mode.In this case, the unit works in heating only mode,the same as a common air-cooled heat pump unit.
Cooling + Hot Water
When both cooling and hot water are required, a customer can choose the cooling + hot water mode.In this case, the unit automatically starts the air conditioning module to provide chilled water for the air conditioner, and starts the hot water module to generate hot water.
Heating + Hot Water
When both heating and hot water are required, a customer can choose the heating + hot water mode.In this case, the unit takes air conditioning as the first priority, and generates hot water in idle periods to meet hot water requirement. A customer can also specified a time period when the unit works in hot water mode.
Hot Water Mode
When hot water is required and air conditioning is not required, a customer can choose the hot water mode. In this case, the unit only provides hot water, and works as a common air source heat pump hot water unit.
