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: An air-conditioning system including a primary circuit and a secondary circuit is provided. The primary circuit includes a flow of refrigerant, an evaporator and a chiller configured to exchange heat between a coolant and the refrigerant. The secondary circuit includes a heat exchanger in fluid communication with the chiller to receive the coolant. The heat exchanger includes a phase change material in heat exchange relationship with the coolant, such that the coolant exchanges heat with the phase change material to store thermal energy in the phase change material. The air-conditioning system is implemented in a machine in which during an idle-off state, the stored energy in the heat exchanger is discharged to provide an air-conditioning effect.

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。

Abstract: An idle reduction engine shutdown and restart system for a machine is disclosed. The machine can include an engine operably connected to a drivetrain including ground engaging propulsion members. The drivetrain can be configured to transmit mechanical energy between the engine and the ground engaging propulsion members. The idle reduction engine shutdown and restart system for the machine can include a starter operatively associated with the engine and configured to effectuate ignition of the engine. The idle reduction engine shutdown and restart system for the machine can further include an idle reduction engine shutdown and restart controller electronically and controllably connected to the engine and configured to shut down the engine in an engine shutdown mode. The idle reduction engine shutdown and restart controller can additionally be electronically and controllably connected and configured to actuate the engine and the starter to start the engine in one or more of an initial engine start mode and one or more engine restart modes.
