A vehicle that includes a frame, a prime mover, an alternator, a cabin, a HVAC system, and a power source. The prime mover is operable in a first mode that is configured for driving the vehicle and a second mode that is configured for standby operation of the vehicle. The cabin includes walls that define a space and that have insulation to insulate the space. The HVAC system is in communication with the cabin to condition the space, and includes a cooling system, a heating system, and a sorption system that dehumidifies air provided to the space. The power source has a battery that is in electrical communication with the alternator and the HVAC system to supply power to the HVAC system from the battery when the prime mover is in the first mode and when the prime mover is in the second mode.

A refrigeration system for providing conditioned air to a space includes a compressor operable to compress a refrigerant, a condenser configured to receive the refrigerant from the compressor, an expansion device configured to receive the refrigerant from the condenser, a desiccant operable to adsorb moisture from an airflow flowing through the desiccant such that the airflow is substantially dehumidified, and an evaporator assembly configured to receive the refrigerant from the expansion device and the airflow from the desiccant. The evaporator assembly is operable to condition the airflow prior to discharge from the evaporator assembly. The refrigeration system also includes a heat exchanger configured to selectively receive the refrigerant from at least one of the compressor and the condenser. The heat exchanger is in communication with the desiccant such that the refrigerant in the heat exchanger desorbs moisture from the desiccant.

An enclosure for storing temperature sensitive goods. The enclosure includes a wall that has an interior wall member and an exterior wall member that is spaced apart from the interior wall member to define a gap. The interior wall member partially defines the conditioned space. The enclosure also includes an insulation member that is disposed between the interior wall member and the exterior wall member within the gap. The insulation member has a vacuum insulation panel and foam insulation that is positioned on both sides of the vacuum insulation panel to separate the vacuum insulation panel from the interior wall member and the exterior wall member. The vacuum insulation panel and the foam insulation cooperate to insulate the conditioned space.

A rotary vane motor for efficiently extracting mechanical energy from an expanding gas at low rotational speeds is provided. The motor includes a housing having a cylindrical enclosure, a rotor having a plurality of radially oriented slots, a plurality of vanes slidably movable in the slots, a shaft for rotatably mounting the rotor in an eccentric position within the housing enclosure, and a slidable connection between the rotor and the shaft for equilibrating close clearances between the rotor and the side edges of the vanes and the inner surfaces of the housing to minimize inefficiencies due to blow-by and friction. Additionally, the materials forming the rotor, the vanes, and the housing are all selected to have the same thermal coefficient of expansion so that the vanes tightly interfit within their respective slots and the sealing surfaces of the housing over a temperature range spanning the cryogenic temperatures associated with the prefeffed drive gas, and maximum ambient temperatures. Finally, gas conducting structures in either the rotor or the vanes are provided for admitting a portion of the drive gas to the inner edges of the vanes to radially push the outer edges into tight sealing engagement with the inner surfaces of the housing.

A refrigeration system, which conditions the air of a conditioned space via heating and cooling cycles, includes a heat exchanger and, in a first embodiment, heat pipes. A cryogen is circulated through the heat exchanger during a cooling cycle. During a heating cycle the flow of cryogen is terminated and heat is transferred into the heat exchanger via the heat pipes. In another embodiment, the temperature of evaporation of a liquid cryogen in the heat exchanger is selected according to the desired temperature of the conditioned space, via selectable cryogen flow paths which provide different pressures and thus different evaporation temperatures. Vaporized cryogen drives a motor connected to a fan which circulates air between the conditioned space and heat exchanger. In still another embodiment, the mass flow rate of liquid cryogen is controlled as a function of the degree of superheat in evaporated cryogen exiting the heat exchanger, and as a function of a predetermined floor temperature of conditioned air discharged into the conditioned space.
摘要:
A refrigeration system associated with a conditioned space to be controlled to a predetermined set point temperature via heating and cooling cycles. The refrigeration system includes a fluid flow path through which a predetermined fluid is circulated. The fluid flow path includes first, second and third heat exchangers. The first heat exchanger is disposed to condition air of the conditioned space, the second heat exchanger is in heat exchange relation with cryogenic cooling apparatus, and the third heat exchanger is in heat exchange relation with heating apparatus. The first and second heat exchangers are interconnected when the conditioned space requires a cooling cycle, and the first and third heat exchangers are interconnected when the conditioned space requires a heating cycle. Cryogen of the cryogenic cooling apparatus is thus not expended to heat the conditioned space, nor used for defrosting purposes.
