Note:
Working conditions for nominal cooling capacity test: water flow rate 0.172m3/(h.kw); temperature of outlet water 7°C;
outdoor ambient temperature 35°C.
Working conditions for nominal heating capacity test: water flow rate 0.172m3/(h.kw); temperature of outlet water 45°C;
temperature of outdoor dry/wet bulb 7°C/6°C.
The sound level is tested before the unit leaves factory. Practically, due to environment noise and other factors, the sound level tested might
be different from those listed in the above table.

Description
1. Units of this series feature a classic European air conditioner design (chilled water/heat pump + indoor terminals) for precise temperature control. The units can provide you with a comfortable, healthy and graceful working/living environment. The uni ts feature a heat sink mechanism using circulatory air and needs no cooling tower. This not only saves the cost of the cooling tower, but also saves precious building space. Units of this series feature various models and dimensions to meet different installation requirements.
2. Units of this series are equipped with fully hermetic compressors which are stable, advanced and reliable. All components have undergone strict integration and compatibility test to ensure optimized performance and efficient/energy-saving operation all year round. The EKAC120B integrated units perfectly unify the parallel compressor technology and electronic throttle technology to quickly modulate the cooling capacity to the set value, thereby making sure that the units are most energy efficient. The EER is even higher with partial workload. For example, for EKAC120B unit, the EER is 6% higher with 75% of workload, 11% higher with 50% of workload, and 16% higher with 25% of workload. The solenoid interlock control function can shut down the master unit and water pump automatically when all fans have stopped working, making the unit more energy saving.
3. The EKAC120B integrated unit features a 500-step PMV electronic expansion valve for precise PID flow control, dynamic and real-time adjustment of the cooling capacity and accurate water temperature control. An electronic expansion valve with a large flow modulation range helps optimize the performance of various parts of the system, and makes the system work reliably under any workload. The units can automatically adapt to changing ambient temperatures, completely eliminating cooling system vibration during the capacity modulation process.
4. Long and strict tests prove the unit can work reliably in an environment as hot as 48°C (cooling) or a
