■ Rated cooling work conditions: outdoor dry bulb: 35°C; outlet water temperature: 7°C; water flow 0.172m3/(h·kW).
■ Rated heating work conditions: outdoor dry/wet bulb: 7°C/6°C; outlet water temperature: 45°C; water flow 0.172m3/(h·kW).
■ Rated working conditions for total heat recovery units: inlet/outlet water temperature of chilled water: 12°C/7°C; inlet/outlet temperature of
hot water 40°C/45°C.
■ For on-site electric wiring, see the name plate or installation menu of the unit.

 

 

More Energy Saving

 

The heat recovery technology improves cooling efficiency, reduces power consumption, and extends the service life of a unit. The total heat recovery technology recovers all condensate heat, saves power consumed by the fan of the heat exchanger at the air side, and reduces energy consumption by more than 15%.

 

One Unit for Three Purposes

 

One unit can be used for three purposes: cooling, heating, and free hot water. The unit can provide hot water with a temperature up to 65°C to meet guest house showering, kitchen cleaning, and factory hot water consumption requirements, thus saving investment in hot water equipment.

 

Less CO2 and More Environment Friendly

 

EK air conditioners feature a leading-edge total heat recovery technology to use waste heat, greatly save energy, and effectively mitigate the heat island effect in cities due to waste heat dissipation.

 

Easy Installation

 

The unit can be easily installed outside and requires no dedicated equipment room or operator. Free hot water is available as long as you connect the hot water pipes.
