高效率的机械冷藏车应保证在低能耗下货物的经济运输。在这方面,加热系统中蕴藏着巨大的潜力。目前,加热系统的全部热量是通过使用由柴油发电机组产生的电能供电的电阻器获得的。利用建筑物采暖的热泵原理将会节省电能。机冷车的方便之点在于,制冷装置的大部分部件也可以用于热泵装置。德累斯顿交通学院有人对这一课题进行了理论研究。计算结果表明,在机冷车上采用热泵,与使用电阻器加热相比较,可以节省柴油5～16％。德骚车辆工厂建造的试验台可以获得制冷装置-热泵装置工作的数据,也可以验证理论研究的结果。试验台为了进行试验,将批量生产的FAL056/7型机冷车的制冷装置改造成热泵式装置。采用标准部件的试验台可以完全保证热泵式装置的工作。该热泵式装置的系统简图如图
High-efficiency mechanical refrigerated trucks should ensure the economical transportation of goods under low energy consumption. There is tremendous potential in the heating system in this regard. Currently, the entire heat of the heating system is obtained by using a resistor powered by the electrical energy generated by the diesel generator. Heat pumps that use building heating will save energy. The convenience of a chiller is that most of the components of the chiller can also be used in heat pump installations. Dresden Institute of Transportation Someone on the subject of a theoretical study. The calculation results show that the use of heat pump in the cold machine, compared with the use of resistor heating, can save 5-16% of diesel. Test rigs built in the Dessau Vehicle Factory receive data on the operation of the refrigeration unit, the heat pump unit, as well as the results of theoretical studies. Test bench In order to carry out the test, the mass production of the FAL056 / 7 machine-type refrigeratory refrigeration unit into a heat pump device. The use of standard components of the test bench can fully guarantee the heat pump device. The heat pump system diagram shown in Figure
