In this projet ,we should control the temperature and humidity of blowing-in ,the temperature diffenence between cooling water in and out,and the turnning on or off sequence of the devices. We decide the logical relation based on the physical condition,then have acquaintance with those devices.make sure the equipment have be connected in correct way.we programme the LAD and download it to the PLC.at the last finish the loop,and regard the contronl performance. As an example, at the second section we describe the temperature contorl of the blowing-in.at the first,introduce theworking theroy and picture it .secondly,each device has been explained.with the help of HMI software,it show thecontrol peformance on the PC. In the end,some deficiency is listed down,and it¡¯s also couid be useful for the reader. Keywords: HVAC automation PLC
