济南空调回收中央空调的自动控制系统主要包括温度传感器、自动化控制电路和微电脑等。利用温度差的变化量作为反馈信号，选用温度传感器采集温度模拟信号，通过转换后提供给控制电路进行数据处理。由控制电路完成对各个电器部件的运行进行控制。

　　Automatic control system of Ji'nan air conditioning recovery of central air conditioner including temperature sensor, automatic control circuit and a microcomputer. As the feedback signal by using the variation of temperature difference, the temperature sensor to collect temperature signal, through the converted supplied to the control circuit for data processing. Completed by the control circuit to control the operation of the various electrical components.

　　Ji'nan air conditioning recovery of central air conditioning system according to the difference between the change of controller set temperature and the controlled object is the temperature, using computer technology and related control circuit, electrical components on the central air conditioning system, thereby indirectly control the difference variation, the difference is minimal. In the central air conditioning system with variable frequency compressor as an example, in the central air conditioning system operation process, due to some reasons to increase the central air conditioning room load, temperature sensors to collect the indoor temperature change, the change of temperature sampling signal to the indoor microcomputer through the electronic circuit. The indoor computer will receive the electrical signal that indicates the temperature of Ji'nan air conditioning recycling box digital processing into digital signal is sent to the outdoor microcomputer. An outdoor microcomputer accept serial signal indoor microcomputer according to the communication protocol, adjustment of the running state of the compressor, refrigerant circulation to improve the unit time, the change of load output capacity and indoor central air conditioning system to adapt.

　　空气冷却器是利用制冷剂在管内沸腾吸热，由液体变成气体，使管外被迫流动的空气被冷却。寄来自冷凝高压制冷剂液体经液体分配器分液后，流经各自的毛细管节流、降压、降温后进入蛇形传热管，在管内沸腾吸收外空气的热量，最后经集气管汇总被压缩机吸走。由于翅片管表面的温度很低，当湿空气流过翅片管时，空气中的水蒸汽将凝结成水析出，因此中央空调器在工作时有凝结水排出。蒸发器翅片管一班为纯铜，翅片为铝质，其厚度和节距以不同生产厂家及不太难过设备规格而定。
