Abstract: 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).

Abstract: A trailer refrigeration system comprising: an electricity generator (22); an electricity-generator engine (21) for driving the electricity generator (22); a converter (23) for converting ac electric power generated by the electricity generator (22) into dc electric power; an inverter (24, 25, 26) including inverters (24), (25), (26) each for converting dc electric power from the converter (23) into ac electric power; a refrigerant circuit (30) having an electric compressor (31) and a fan (35, 36) including fans (35), (36), the electric compressor (31), the fan (35), and the fan (36) being driven respectively by ac electric power from inverters (24), (25), (26); and a control means (40) for individually controlling the speed of rotation of the electric compressor (31), the fan (35), and the fan (36).

Abstract: An engine unit (U1) containing an electricity generator (22), an electricity-generator engine (21), and a console panel (29) is mounted in the lower part of a trailer. A refrigeration equipment unit (U2) containing a converter (23), inverters (24, 25, 26), and a refrigerant circuit (30) is mounted in the ceiling part of a refrigeration storage compartment (C). The engine unit (U1) and the refrigeration equipment unit (U2) are connected together by electric wiring.
