A truck air conditioning device belongs to the technical field of mining truck air conditioners. A main shaft (13) of the compressor (1) is simultaneously connected with an output shaft of the driving motor (12) and a truck engine through a transmission mechanism, a refrigerant outlet of the compressor (1) is communicated with a refrigerant inlet of the four-way valve (2), and the other three ports of the four-way valve (2) are respectively connected with the refrigerant inlet of the compressor (1), a refrigerant inlet of the condenser (10) and one port of the switching valve (4). A refrigerant outlet of the condenser (10) is connected with the expansion valve (8) in series and then communicated with a refrigerant inlet of the indoor unit (3) and a refrigerant inlet of the evaporator (5) at the same time through the reversing valve (7), and a refrigerant outlet of the evaporator (5) and a refrigerant outlet of the indoor unit (3) are connected with the other two ports of the switching valve (4) respectively. The truck air conditioning device is used on a mining truck, switching between a driving mode and a parking mode can be achieved through one compressor, and the installation and maintenance cost of the compressor is reduced.
一种货车空调装置,属于矿用汽车空调技术领域。压缩机(1)的主轴(13)通过传动机构同时与驱动电机(12)的输出轴和货车发动机连接,压缩机(1)的冷媒出口与四通阀(2)的冷媒入口连通,四通阀(2)的其余三个端口分别与压缩机(1)的冷媒入口、冷凝器(10)的冷媒入口以及切换阀(4)的一个端口连接,冷凝器(10)的冷媒出口串联膨胀阀(8)后通过换向阀(7)同时与内机(3)的冷媒入口和蒸发器(5)的冷媒入口连通,蒸发器(5)的冷媒出口和内机(3)的冷媒出口分别连接切换阀(4)的其余两个端口。本货车空调装置用于矿用货车上,依靠一个压缩机即可实现行车和驻车两种模式的切换,降低了压缩机的安装和维护成本。
