Abstract： Since the traditional air supply system of air conditioner can't supply the air better in large temperature difference environment， a new optimization design scheme of air supply system for air conditioner in large temperature difference environment is put forward. The dew point unit of the machine is effectively optimized to change the sensitivity of the traditional dew point unit for humidity and temperature， and reduce the temperature difference of the internal friction to the minimum. The enthalpy and indoor air supply are reset， and effectively controlled and calculated by means of the sensitive chip in large temperature difference environment， which is convenient for self?reset according to temperature difference in different environments. The temperature rising systems of draught fan and air duct are optimized to maintain the low power consumption while ensuring the regulation ability in large temperature difference environment. In order to verify the validity of the optimization scheme for the air conditioner′s air supply system in large temperature difference environment， the contract simulation experiment was designed. The experimental data shows that the optimization scheme can adjust the large temperature difference effectively.

随着气候的变化，温室效应、厄尔尼诺效应等效应突发的概率越来越多，加上现代城市中的绿植面积的减少，城市的温差变得越来越大[1?2]。室内外的温差较大造成普通的空调设备出现超负荷的工作环境，虽然空调的调节能力很强但是依然无法满足在大温差环境下室内温度的调节[3?5]，特别是在高温的环境下，由于温差较大同时送风功率的极限值是一个定值，因此需要对空调的送风系统进行有效的优化，这样才能满足在大温差环境下的室内温度的调节[6?8]。针对上述问题，提出一种大温差环境下空调送风系统优化方案，为了验证本文设计的大温差环境下空调送风系统优化方案的有效性，设计了对比仿真试验，通过实验数据有效的证明了本文设计的优化方案有效性。……
