如此循环往复,不断地将热源的热能传递给冷凝水。根据热力学定律,有:Qg=Qd+A,根据热力学第二定律,压缩机所消耗的电功A起到补偿作用,使得制冷剂能够不断地从低温环境吸热(Q,并向高温环境放热(Qg),周而复始地进行循环。压缩机的能耗是一个重要的技术经济指标,一般用性能系数(coefficientofperformance,简称COP)来衡量装置的能量效率,其定义为:COP=Qg/A=(Qd+A)/A=1+Qd/A显然,热泵COP永远大于1。

运转环境的检查。
⑴PLC运转环境温度在0~60℃。温度过高将使得PLC内部元件功能恶化和毛病添加,尤其是CPU会因“电子搬迁”表象的加快而下降PLC的寿数。温度偏低,模仿回路的安全系数也会变小,超低温时能够致使操控体系动作不正常。处置的方法是在操控柜装置适宜的轴流电扇或许加装空调,并留意常常检查。
⑵环境相对湿度在5%~95%之间。在湿度较大的环境中,水分简单通过模块上的IC的金属表面的缺点侵入内部,致使内部元件功能的恶化,使内部绝缘功能下降,会因高压或浪涌电压而致使短路;在极端枯燥的环境下,MOS集成电路会因静电而致使击穿。
⑶定时吹扫内部尘埃,以确保风道的疏通和元件的绝缘。
⑷检查PLC的装置状态。各PLC单元固定是不是结实,各种I/O模块端子是不是松动,PLC通讯电缆的子母连接器是不是刺进并旋紧,外部连接线有无损害。
⑸检查PLC的程序存储器的电池是不是需求替换。
