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.

Abstract: An air inlet 16 is formed in a rear surface side vertical wall section 10b, or a single surface of an apparatus main body 10, and an air stream path that extends from the air inlet 16 of the rear surface side vertical wall section 10b to air outlets 14a and 14b formed upwardly aslant in an inclined surface section 13 that is also the single surface provided in the opposite direction. In this air stream path are arranged an air-cooling absorber 17, an air-cooling condenser 19 and fans 15a and 15b provided with their fan axes arranged upwardly aslant in correspondence with the air outlets 14a and 14b. With this arrangement, the air-cooling absorption type refrigerating apparatus is made to have an integrated air intake space and a reduced installation area, and an air stream path extending from the air inlet to the air outlets is made to have a reduced draft loss to allow the flow velocity distribution of the air stream of the heat exchange section to be uniformed.
