随着新款B系列发动机的应用,宝马在装备B48、B58的4缸和6缸发动机的新款车型上逐渐也开始使用新型空调制冷系统,新型系统优化了空调系统功率消耗,在同等制冷功率的前提下,新型系统能够降低压缩机功率,并在启停装置MSA熄火状态下延长制冷时间,进一步降低了油耗,也算作是宝马一项附加高效动力措施。我们先来了解一下传统空调系统制冷原理,空调系统制冷剂循环示意图,如图1所示。所有空调系统并不能产生冷气,而是将吸收车内的热量排到车外,是个热量的搬运工。制冷剂循
With the new B Series engine application, BMW has gradually begun to use the new air conditioning and refrigeration system on the new models equipped with the B48 and B58 4-cylinder and 6-cylinder engines. The new system optimizes the air conditioning system power consumption. In the same premise of cooling power Under the new system can reduce the compressor power, and start and stop device MSA stalling state extend the cooling time, to further reduce fuel consumption, can be considered as an additional BMW high efficiency power measures. Let us first understand the traditional air conditioning system cooling principle, air conditioning system refrigerant cycle diagram, shown in Figure 1. All air-conditioning system does not produce air-conditioning, but will absorb the car’s heat discharged to the car, is a heat porter. Refrigerant circulation
