THE DESIGN AND PERFORMANCE ANALYSIS OF SINGLE-STAGE COMPRESSION REGENERATIVE REFRIGERATION CYCLE USING MIXED REFRIGERANTS Study on Characteristics of the Ejector in Quasi Two-Stage Compression Heat Pump Coupled with Ejector 混合工质单级压缩回热制冷系统的设计与性能分析准二级压缩&喷射复合热泵系统用喷射器的性能研究
Third, set up two kinds fire pool regenerative three-dimensional model: without and with the water distribution. Used for simulation of the ground source heat pump units for heat storage of various factors on the thermal efficiency of the storage effect. 第三,建立两类消防水池蓄热三维模型:不加布水器的和添加布水器的,用于模拟地源热泵机组进行蓄热时的各种因素对于蓄热效率的影响。
The regenerative braking system of the hydraulic hybrid vehicle ( HHV) is made up of pump/ motor, accumulators, feedback components and control system. 液压混合动力车(HydraulicHybridVehicle,简称HHV)再生制动系统由液压泵/马达、蓄能器、反馈元件以及控制系统组成。
It is easy to control and carry out energy recovery and release because the energy regenerative system of hydraulic hybrid vehicle adopts constant displacement secondary component ( pump/ motor), but there still exists some technical defects. 在已有的液压混合动力汽车能量再生系统中,选用定量式二次元件(泵/马达)作为能量转换装置,具有控制方法简单,易于实现能量回收与释放等特点,但仍存在一些技术上不足。
