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 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. Long and strict tests prove that units of this series can work reliably in an environment as hot as 48°C (cooling) or as cold as -10°C (heating). With a smart split design, all water pipes can be installed indoor to prevent freezing during cold winters. The units can work with boilers to meet heating requirements in areas which are extremely cold in winter. The units feature built-in high/low pressure protection, cooling freezing protection, winter freezing protection, compressor overload protection, water pressure-drop switch etc. to maximize reliability. In case of any failure, the micro-computer controller provides alarms using sound and indicators on a real-time basis. Besides unconditional manual defrosting, the controller also supports efficient auto defrosting based on multiple parameters during heating operations.
4. The units feature a strengthened vibration isolation case and multi-grade sound dampening. Thanks to a fully hermetic scroll compressor and a low-rev high-efficiency heat-sink fan, the operation sound and vibration of the units are brought down to an industry leading level. With an innovative
