The invention provides a method of operating a cooling system having dual independent refrigerant loops. A method of operating a cooling system for a vehicle including providing a cooling system including a coolant loop having a coolant valve, a first refrigerant loop having a first compressor and a first chiller configured to exchange heat with the coolant loop, a second refrigerant loop having a second compressor and a second chiller configured to exchange heat with the coolant loop, and a cooling system controller operably coupled to the first compressor, the second compressor, and the coolant valve. The coolant valve is configured to selectively direct or prevent the flow of coolant between the battery and each of the first chiller and the second chiller. The method further includes operating the cooling system in one of a second chiller only mode, a first chiller only mode, an air conditioning (AC) only mode, a first refrigerant loop only mode, and a dual refrigerant loop mode.
本公开提供“操作具有双独立制冷剂回路的冷却系统的方法”。一种操作车辆的冷却系统的方法包括提供冷却系统,冷却系统包括:冷却剂回路,其具有冷却剂阀;第一制冷剂回路,其具有第一压缩机和被配置为与冷却剂回路交换热量的第一冷却器;第二制冷剂回路,其具有第二压缩机和被配置为与冷却剂回路交换热量的第二冷却器;以及冷却系统控制器,其可操作地联接到第一压缩机、第二压缩机和冷却剂阀。冷却剂阀被配置为选择性地引导或防止冷却剂在电池与第一冷却器和第二冷却器中的每一者之间流动。方法还包括以仅第二冷却器模式、仅第一冷却器模式、仅空调(AC)模式、仅第一制冷剂回路模式和双制冷剂回路模式中的一者操作冷却系统。
