具体调整步骤：1)拆下膨胀阀的防护盖；2)转动调整螺杆2—4圈；(专业空调的膨胀阀一般采用压杆式和散型齿轮式，散型齿轮式是用一个小齿轮带动一个大齿轮，调节的圈数比较多，一般可以调2~4圈；压杆式可调圈数比较少，每次调1/4圈；O65空调的膨胀阀采用散型齿轮式)3)等10分钟后，从新测量过热度，是否在正常范围，不是的话，重复上述操作。调节过程必须小心仔细。(如果膨胀阀油堵严重，应用无水乙醇进行清洗，再从重新装上；失去调节功能的膨胀阀应更换；更换时，注意安装位置和做好保温)三、制冷系统的冷凝压力1.空调冷凝器脏机房空调一般采用风冷式冷凝器，

它由多组盘管组成，在盘管外加肋片，以增加空气侧的传热面积，同时，采用风机加速空气的流动，以增加空气侧的传热效果。因片距较小，加上机房空调连续长时间使用，飞虫杂物及尘埃粘在冷凝器翅片上，致使空气不能大流量通过冷凝器，热阻增大，影响传热效果，导致冷凝效果下降，高压侧压力升高，制冷效果降低的同时，消耗了更多的电力，冷凝压力每升高1 kg/cm2，耗电量增加6～8%。对策：结合空调使用环境，根据结灰情况，定期对空调外机进行冲洗，具体方法是用水或压缩空气，由内向外冲洗空调冷凝器，清除附在冷凝器上的杂物和灰尘，现在杭州电信分公司每年两次对机房空调外机进行冲洗，保证良好的散热效果的同时，节约了大量的能源。
