Ejector Cycle® development has been under way to improve refrigeration cycle performance and increase its efficiency in light of global environmental conservation. Ejector Cycle® can be applied to cool boxes that cool drinks using the refrigeration cycle of the vehicle air-conditioning system. We commenced deliberating Ejector Cycle® application to improve cool box system performance. Difficulties associated with the cool box include the decline in cabin air-conditioning performance due to simultaneous operation of the cabin air conditioning and cool box. We have solved this problem by using an ejector to achieve continuous operation with two evaporator temperatures in the same system. Furthermore, we have configured the cycle to be suitable for vehicle air-conditioning systems, designed a high-efficiency two-stage variable ejector, and addressed various system problems. The result is successful commercialization of the Ejector system (hereafter, it is shown EJECS®(EJEctor Cycle System) cool box, which provides substantial performance improvements at a level unachievable using a conventional system (Cabin air conditioning: +15% in performance; Refrigeration: 20% reduction in cooling time). The development is outlined below.
