求翻译：河水冷却系统是个新型系统，利用温度较低的河水作为建筑空调系统的冷却剂。这个系统可以降低建筑的总电能消耗以及二氧化碳排放量，从而可观地降低能源费用。是什么意思？

Water cooling system is a new system, the use of low water temperature of air conditioning system as the coolant. This system can reduce the building's total energy consumption and carbon dioxide emissions, thereby considerably reducing energy costs.

river water cooling system is a new system using a lower temperature, the river water as a coolant in air-conditioning systems architecture. This system can reduce the overall power consumption as well as building 2 carbon dioxide emissions, thereby substantially lower energy costs.

The river water cooling system is a new system, takes the construction air-conditioning system using the temperature low river water the cooling agent.This system may reduce the construction the total electrical energy consumption as well as the carbon dioxide withdrawal, thus reduces the energy exp
