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).
