1.前言在检定和验证运输制冷设备时使用大型量热室,由电热器来平衡冷负荷。这需要精确地测定输入电能和量热器的获热量及热耗。这是目前塞英金(Thermo·King)公司、其它制造单位和一些独立的实验站成功的使用方法。最近塞英金公司已扩充和完善它在明尼阿波利斯市的工程测试设备,设置更多的具有较大能力的试验间。大的房间能更真实地模拟拖车、汽车或集装箱的内部。此外,在量热器内由自动数据记录仪表测定热量,这比以前不用量热器而测定空气容量和焓值是一种改进。 2.试验间的介绍 1号试验间是一个5m×26m的独立式房间,具有加热和制冷能力。2号试验间具
1. INTRODUCTION In the verification and verification of transport refrigeration equipment, a large amount of heat chamber is used to balance the cooling load by an electric heater. This requires accurate determination of heat input and calorific power and heat loss. This is the current successful use of Thermo King, other manufacturing units and a few independent experimental stations. Cefid has recently expanded and improved its engineering test facility in Minneapolis, setting up more test rooms with greater capabilities. Larger rooms can more truly simulate the interior of a trailer, car or container. In addition, measuring calorie by automatic data loggers in a calorimeter is an improvement over the previous determination of air volume and enthalpy without a calorimeter. 2. Introduction of test room 1 test room is a 5m × 26m free-standing room, with heating and cooling capacity. 2 test room with
