本文在深入分析大空间VAV空调系统室内温度控制方法的基础上，得出由于室内垂直温度梯度的影响，传统的通过检测室内回风管温度作为室内温度的控制依据的控制方法具有一定的不合理性。本文利用PHOENICS软件对一大空间商场VAV空调系统进行了模拟，依据模拟结果，通过采用温度修正的优化方法对回风温度检测值进行优化，使得温度检测值与实际需求温度值更贴近，降低了VAV空调系统的运行能耗，达到节能的目的，风机可节能25.4%。
本文在深入分析大空間VAV空調繫統室內溫度控製方法的基礎上，得齣由于室內垂直溫度梯度的影響，傳統的通過檢測室內迴風管溫度作為室內溫度的控製依據的控製方法具有一定的不閤理性。本文利用PHOENICS軟件對一大空間商場VAV空調繫統進行瞭模擬，依據模擬結果，通過採用溫度脩正的優化方法對迴風溫度檢測值進行優化，使得溫度檢測值與實際需求溫度值更貼近，降低瞭VAV空調繫統的運行能耗，達到節能的目的，風機可節能25.4%。

Based on t he in-depth analysis of temperature control method of VAV air-conditioning system for large-scale rooms, the ordinary control method by using the return air temperature as the control basis has certain rationality for the influence of the indoor vertical temperature gradient. This article uses PHOENICS software to simulate a VAV air-conditioning system of a large space mall. According to the simulation results, using the temperature correction opti-mization method to optimize the testing value of return air temperature can make the testing value more close to the actual de-mand temperature value. The energy consumption of the VAV air-conditioning system operation is decreased. It can achieve the goal of energy saving and the fan can be energy-saving 25.4%.
