由清华大学热能工程系与广州市胜风电子机械工业公司共同协作研制的两种矿用空调机:DFD—52顶置式防振空调机组和ZQFR_s—35重型汽车空调机组,于1991年3月7日在北京通过由国务院重大技术装备露天矿办公室和国家教委主持的鉴定验收。这两种空调机是按照由清华大学承担的国家“七五”攻关项目“矿用防振式空调设备研制”的要求进行研制的。DFD—52顶置式防振空调机组主要用于牙轮钻机、电
Two types of mine air conditioners jointly developed by the Department of Thermal Engineering of Tsinghua University and Guangzhou Shengfeng Electronic Machinery Industry Co., Ltd.: DFD-52 top-mounted anti-vibration air conditioning unit and ZQFR_s-35 heavy-duty automotive air-conditioning unit, in March 1991. 7 Japan passed the appraisal and acceptance presided over by the State Council’s major technical equipment open-pit mine office and the State Education Commission in Beijing. The two types of air conditioners were developed in accordance with the requirements of the national “Seventh Five-Year Plan” research project “Development of Vibration-proof Air Conditioning Equipment for Mines” undertaken by Tsinghua University. DFD-52 top-mounted anti-vibration air-conditioning unit is mainly used for roller rigs and electric
