2·New flooded of heat exchange tubes for heat transfer enhancement and optimization of the design refrigerant distributor, the heat transfer coefficient is three times the conventional dry-type evaporator, and improve the unit cooling capacity and energy efficiency;

3· Unit with seven security protection, real-time monitoring control high& low pressure, discharge temperature, water temperature , ensuring the safe operation of the unit;

4· Unit according to changes in water temperature ,using the fuzzy theory to adjust the compressor capacity to match the actual air-conditioning load stepless, significant energy saving effect.
