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

Trailer refrigeration system

An outdoor unit (,), a parent unit (,), a plurality of child freezers, and a plurality of child refrigerators are provided. The child freezers are disposed in individual frozen display cases, while the child refrigerators are disposed in individual refrigerated display cases. A refrigerant heat exchanger (,) is disposed in only the parent unit (,). The outdoor unit (,) and the refrigerant heat exchanger (,) form a primary refrigerant circuit. A secondary refrigerant circuit is provided in the parent unit (,). Refrigerant circulates through the secondary refrigerant circuit, passing through the refrigerant heat exchanger (,). Each child freezer is provided with a refrigeration utilization side heat exchanger (,) and the heat exchanger (,) and the refrigerant heat exchanger (,) form a secondary refrigerant circuit through which refrigerant circulates. Together with the outdoor unit (,), a heat exchanger which is disposed in each of the child refrigerators forms a secondary refrigerant circuit of a unary refrigeration cycle.
