A system for controlling a temperature a within an interior volume of a cargo trailer adapted to transport perishable goods is described herein. The system includes a fluid distribution assembly and a monitoring system. The fluid distribution assembly is configured to selectively channel a flow of cryogenic cooling fluid into the cargo trailer interior volume to facilitate adjusting a temperature within the interior volume. The monitoring system includes at least one sensor for sensing an environmental parameter of the cargo trailer, and a controller coupled to the sensor and to the fluid distribution assembly. The controller is configured to receive a monitoring signal indicative of the sensed environmental parameter, determine an environmental condition of the cargo trailer as a function of the environmental parameter, and provide a notification signal if the determined environmental condition is different than a predefined environmental condition.

A heat exchanger device provides refrigeration in refrigerated vehicles operated by liquefied natural gas (LNG) which must first be regasified. The great temperature difference between heat-discharging cooling chamber air and heat-absorbing LNG evaporating at up to −161° C. conducts the heat flow via an introduced intermediate medium circulating in a closed circuit to avert the risk of combustible natural gas leaking. The intermediate medium is non-combustible, environmentally-benign liquid heat exchange media having low viscosity. The liquid heat exchange media operating temperature is kept above −85° C. using an additional thermal resistance in the heat exchanger which evaporates the LNG, so that the heat flow flows with sufficient temperature drop. A thin protective dry gas layer formed using sheathing tubes enclosing a tubular heat exchanger's tubes coaxially serves as this thermal resistance. Possibly escaping natural gas is determined by monitoring pressure in the layer, and the LNG supply interrupted.

A method for controlling a power system that powers a load is provided.
