对五大卷烟厂７台组合式空调机组的质量进行检查和检测，发现存在机组风量、风压偏低，表冷器排数偏多，风量与冷量不匹配，表冷器后带水，机组结构不合理等问题，提出了改进意见。认为工业用机组存在的上述问题与一般组合式空调机组具有共性。 Examined and inspected the quality of the 7 combined air-conditioning units in the five major cigarette factories and found that the air volume and the air pressure of the unit were low, the number of coolers was too much, the air volume and the cooling capacity did not match, and the water cooler was behind the units. Unreasonable structure and other issues have raised suggestions for improvement. It is believed that the aforementioned problems existing in industrial units are common to general combined air-conditioning units.
