摘要
结合陶瓷PTC辅助电加热器的原理,介绍在风管式送风空调机组中采用陶瓷PTC辅助电加热器的开发背景,通过对陶瓷PTC辅助电加热器的一系列试验,分析其性能和特征,确定其结构、安装位置以及保护器件等选型依据,并阐述在风管机中风量、静压等对其的影响。
Combined the principle of porcelainous PTC（positive temperature coefficient） heater,illustrates the application background of the PTC as the assistant heater to duct air conditioner.With a series of experiments,analyzes PTC＇s performance and characteriticts,determines its selection basis such as configuration,position in the air conditioner and so on,describes the influence of air flow rate and static pressure.
