But the time available for delivery before the cold plate solution thaws typically limits vehicle use to single-shift operations, although the time available can be extended by the opportunistic plug-in and operation of on-board refrigeration compressors on the way in transit

Embodiment Construction

[0021] figure 1 A vehicle 101 is shown having a body 102 , a chassis 103 and an insulated body 104 . figure 1 An insulated body 104 attached to a vehicle 101 as shown in FIG. 1 is provided with a conventional separately powered refrigeration unit 105 .

[0022] figure 2 A vehicle 101 is shown having a body 102 , a chassis 103 and an insulated body 104 . The vehicle 101 has an engine 106 for propulsion with a direct current (DC) generator 107 attached to the engine 106 . The DC generator 107 is driven by the engine 106 via a belt drive, although it is within the scope of the invention for the DC generator 107 to be driven by the engine 106 via other means such as gears or hydraulic pumps and electric motors. The DC power generated by the DC generator 107 is then conducted to a power converter / inverter 109 for converting the DC power to alternating current (AC) power. As previously described in this specification, the DC generator 107 may generate direct current in the 8 to...

Description

[0001] Citations and Priority Claims to Related Applications [0002] This application is a continuation-in-part of co-pending application Ser. No. 11 / 372,506, filed March 10, 2006, and claims priority thereto. Background technique [0003] Industrial motor vehicles, such as medium or heavy duty trucks, are often used to carry perishable goods such as food and are often provided with an insulated bodywork for this purpose. There are various methods for cooling the interior of an insulated vehicle body, such as using the vehicle's prime mover engine to drive a refrigeration compressor, or by using a separately powered refrigeration unit. Typically, split powered refrigeration unit type systems contain a small auxiliary diesel engine for autonomous operation, and electric motors for loading and unloading positions where there is utility power available. The actual cooling of the interior of the insulated body is achieved by conventional evaporator-to-air heat exchangers. The p...
