风冷型立柜式空调机组的性能试验方法,如采用室内侧空气值法与室外侧空气(?)值法时,则对于室外侧空气焓值法的测试装置,必须在正式进行试验前,附加一个“预备性试验(即‘预试’)”。本文对“预试”的意义、要求、“预试”中存在的主要问题及解决方法都作了详细论述,这对当前有关制造工厂正确进行风冷型立柜式空调机组的性能试验及提高产品质量,有参考价值。 Air-cooled cabinet air-conditioning unit performance test methods, such as the use of indoor air value method and outdoor side air (?) Value method, then the outdoor side of the air enthalpy method test device, must be formally tested before, attached A “preparatory test (ie,” pre-test “). This paper discusses the significance and requirements of ”pre-test“, the main problems and solutions in the ”pre-test", and expounds on the current performance test and improvement of the air-cooled vertical cabinet type air conditioner unit in the manufacturing plant Quality, a reference value.
