Abstract: A method of operating a hybrid temperature control system. The method provides an evaporator, which has a discharge line, a supply line, and a evaporator coil. The evaporator coil is in fluid communication with the discharge line and the supply line. The method also provides a microprocessor, which regulates a supply of a heat absorbing fluid to the evaporator. The method further couples a sensor module to the microprocessor. The sensor module is near the evaporator, senses a temperature of a gas exiting the evaporator, and sends a temperature to the microprocessor. The method also turns off the supply of the heat absorbing fluid to the evaporator when the microprocessor determines that the temperature of the gas exiting the evaporator reaches a predetermined temperature.

Abstract: A temperature control system for a motor vehicle includes a housing having an air inlet and an air outlet, both of which are in fluid communication with an air-conditioned space of the vehicle. An evaporator coil is mounted within the housing and provides a pathway for a heat-absorbing fluid between a heat-absorbing fluid tank and the atmosphere. A blower mounted within the housing between the air inlet and the evaporator coil is driven by the motor vehicle engine, and blows air to be conditioned over the evaporator coil. A heating coil is positioned adjacent to the evaporator coil, and provides a heating flow path for engine coolant such that hot engine coolant flows from the engine, through the evaporator coil, and back to the engine. The heating coil is used to thaw out moisture that has frozen onto the outer surface of the evaporator coil.

Abstract: An apparatus to refrigerate the cargo space of delivery vehicles. It provides an environmentally friendly alternative to conventional mechanical a/c and refrigeration units. Cooling is provided by controlled evaporation of a liquefied gas such as CO2 or nitrogen. Defrost and heating requirements, if needed, are provided by hot engine coolant or by electric heaters powered from the vehicle electrical system. Airflow for the evaporator and for circulation in the temperature controlled space is provided by a blower which is mechanically or electrically driven from vehicle power. This invention can also be applied to multi-temperature control applications. The apparatus is compact and is particularly suited for small inner city delivery vehicles.
