1.空调制冷效果随着气温上升和使用时间延伸有明显下降。这是目前制冷工较头痛的问题之一,往往在同一天内早晚冷气效果可以,中午却不行。有的冷车可以,热车就不行。造成这个问题原因是多方面的,但主要是冷凝条件,它常涉及到发动机散热性能、水箱散热性能、发动机风叶拔风能力等等。用岐管表测量高压往往在196.2 kPa左右,低压也随之上升到39.2kPa左右。
1. Air conditioning and cooling effect with the temperature rise and the use of time significantly decreased. This is one of the most troublesome problems for refrigeration workers at present. In the same day, the effect of air-conditioning may be better in the morning and evening, but not in the noon. Some cold cars can, hot cars will not work. This problem is caused by many reasons, but mainly condensation conditions, it often involves the engine cooling performance, tank cooling performance, the engine blades pull the wind capacity and so on. With the manifold gauge to measure high pressure is often around 196.2kPa, low pressure also will rise to 39.2kPa or so.
