REFRIGERATION DEVICE FOR TRAILER

摘要

A refrigeration unit body ( 31 ) is mounted to a trailer ( 20 ). The refrigeration unit body ( 31 ) includes a refrigerant circuit ( 40 ), an engine ( 50 ) and an electric generator ( 51 ). The refrigeration unit body ( 31 ) has a condensation side passage ( 70 ) formed from the front surface of the refrigeration unit body ( 31 ) to the top thereof. In the condensation side passage ( 70 ), a condenser ( 42 ) and an electrical component box ( 54 ) are disposed in series with condenser fans ( 44 ) for the condenser ( 42 ) and a radiator ( 55 ) in order from upstream to downstream of air flow. In addition, the refrigeration unit body ( 31 ) has an evaporation side passage ( 71 ) formed therein. The condenser fans ( 44 ) in the condensation side passage ( 70 ) and evaporation fans in the evaporation side passage are disposed alternately in the width direction of the refrigeration unit body ( 31 ).
