辅助电加热设备的投入使用可以有效提高柜式空调的制热舒适性。本文实验研究了辅助电加热设备工作模式下，不同工况及风挡等参数对柜式空调各温度参数的影响。研究结果表明，在空调一般制热过程中室内换热器管温稍高于空调出风温度，开启辅助电加热之后，室内换热器管温变化不明显，出风口温度升高明显，并且高于室内换热器管温；在空调进行除霜模式时，空调室内感温包测量温度降低程度明显高于出风口处温度；随着空调出风速度提高，空调的出风温度降低，室内换热器管温也降低；室内环境温度上升速度随室外环境温度降低而降低。

The application of electric auxiliary heating equipment in packaged air conditioner can efficiently improve the heating comfort. The variations of parameters such as tube temperature, outlet air temperature, environment temperature were experimentally studied under different operating conditions in this paper. The results show that the tube temperature is slightly higher than the outlet air temperature without electric auxiliary heating equipment under the heating model, and it turns opposite with the using of electric auxiliary heating equipment. The value of indoor thermometer bulb is lower obviously than the true value of outlet air temperature under the defrost mode of air conditioner. The tube temperature and outlet air temperature decrease as the increasing of the outlet air speed of air conditioner. The increase rate of indoor temperature decreases with the decrease of outdoor temperature.
