双风机空调系统采用可变新风比的焓值控制方法,通过调节新风量的大小以最大限度的利用新风作为冷源来达到节能的目的。本文对比3种不同空调工况下新风的2种不同控制方式以定性分析采用焓值控制方式的节能性,利用海南地区某一实际工程项目计算对比采用焓值控制和不采用焓值控制的能耗差异,得出采用焓值控制能够节省8%的全年冷量和16%的机组运行时间,体现其节能优势。
Dual-fan air-conditioning system uses a variable fresh air enthalpy control method, by adjusting the size of the new air volume to maximize the use of fresh air as a source of energy to achieve the purpose of saving. This paper compares two different control methods of fresh air under three different air conditioning conditions to qualitative analysis of the energy-saving control method using the enthalpy, the use of an actual project in Hainan compared with the calculation of enthalpy control and not using the enthalpy control Consumption differences, come to the use of enthalpy control can save 8% of the annual cooling capacity and 16% of the unit running time, reflecting its energy-saving advantages.
