Abstract: An ejector (200; 300; 400; 600) has a primary inlet (40), a secondary inlet (42), and an outlet (44). A primary flowpath extends from the primary inlet to the outlet. A secondary flowpath extends from the secondary inlet to the outlet. A mixer convergent section (114) is downstream of the secondary inlet. A motive nozzle (100) surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle has an exit (110). The mixer has a downstream divergent section downstream of the convergent section and having a divergence half angle of 0.1-2.0 over a first span of at least 3.0 times a minimum diameter of the mixer.

Abstract: A refrigeration system for a mobile unit includes a refrigeration loop (32), an air duct (70), a sensor (34) and a shock absorption unit (36). The refrigeration loop includes a compressor, a condenser, a refrigerant regulator and an evaporator (64). The air duct directs air from an air inlet to the evaporator, which air duct is defined by first and second panels. The sensor is disposed in the air duct. The shock absorption unit mounts the sensor to and provides a limited thermal conduction path between the sensor and the first panel (22).
