Abstract: A cooling system is disclosed so that an operator cabin can be cooled even if the engine is off. An accumulator can be used to store high-pressure refrigerant until its release. When the compressor is off, the accumulator can release the high pressure refrigerant through the pressure reducer and to the evaporator where heat in the operator cabin can be removed by the refrigerant. An absorption bed with activated carbon can be used to adsorb the refrigerant from the evaporator in order to create a pressure gradient in A/C system. The refrigerant in the accumulator can also be used to subcool a refrigerant in the condenser through a heat exchanger. This allows the operator cabin to be cooled faster up on engine start up. The adsorption bed can also be used to create a pressure gradient in the cooling system.
Abstract translation: 公开了一种冷却系统，使得即使发动机关闭，也可以冷却操作员舱。 蓄能器可用于储存高压制冷剂直到其释放。 当压缩机关闭时，蓄能器可以通过减压器和蒸发器释放高压制冷剂，在蒸发器中，操作员舱内的热量可以被制冷剂除去。 可以使用具有活性炭的吸收床来吸附来自蒸发器的制冷剂，以便在A / C系统中产生压力梯度。 蓄能器中的制冷剂也可用于通过热交换器对冷凝器中的制冷剂进行过冷。 这样就可以在发动机起动时使操作员舱被更快地冷却。 吸附床也可用于在冷却系统中产生压力梯度。
