  • Patent number: 5052191
    Abstract: A method and apparatus for defrosting the outside heat exchanger of a reversible vapor compression refrigeration (heat pump) system. The method and apparatus are particularly suited for use with smaller systems that employ a single fan motor to drive both the inside and outside heat exchanger fans. A heat storage apparatus is mounted in heat exchange relationship with the refrigerant piping between the system flow reversing valve and the inside heat exchanger. During operation in the heating mode, heat from the refrigerant is transferred to and stored in the heat storage apparatus. During operation in the defrosting mode, the refrigerant flow in the system is aligned as in the cooling mode but both fans are shut off. Heat stored in the heat storage apparatus is transferred to and used for defrosting the outside heat exchanger. The apparatus has little or no effect on system operation in the cooling mode.

  • Patent number: 5050403
    Abstract: Disclosed is a cooling container for use in a sorption apparatus. The cooling container is adapted for containing a liquid operating medium, which, during the adsorption phase of operation of the adsorption apparatus, cools off by partial evaporation and solidifies into a solidifying layer starting from the surface of liquid operating medium. In general, the cooling container comprises a vessel and a heat exchanger. The vessel is provided for containing the operating medium, which during the adsorption phase, cools off by partial evaporation and forms the solidifying layer which grows from the surface downwardly into the vessel until the solidifying layer obtains a maximum thickness. The heat exchanger on the other hand is provided for adsorbing heat from a liquid passing through the heat exchanger, and is positioned in the vessel and within the liquid (e.g.

  • Patent number: 5050387
    Abstract: A method and apparatus for maintaining an intended temperature at or close to 0.degree. C. in products affected by variations in temperature, during transport and storage at an ambient temperature deviating from 0.degree. C., while using a container which holds the products and whose walls render heat transfer difficult. The method includes the steps of arranging adjacent the container walls, bottom, lid and the like compartments receiving water or a water mixture so as to provide a water-containing confinement enclosing the product-receiving space in the container from all sides. The container and the water in its wall compartments are then cooled so as to freeze the water. The products are then inserted in the container after it has been moved to a room having a temperature adapted to the products. The container is then closed and used for the transportation and/or subsequent storage of the products.

  • Patent number: 5050402
    Abstract: The invention is directed to a container for environmentally controlled and temperature-regulated transport of perishable goods, the environment-controlling unit being arranged in the essentially cuboid container in the region of the one end face thereof as a component, which is to be allocated to the container and to be separated from it. The environment-controlling unit is broken up into functionally connected components, or is composed of components, which are functionally connected with one another, the components being allocated to the region or regions between the temperature-regulating unit and a container corner post at the side of the temperature-regulating unit. In this way, space within the container is utilized, which previously was unused and was filled with foam, as were the container side walls, in order to avoid heat bridges.

  • Patent number: 5050391
    Abstract: A low energy consumption apparatus and method for treating a gas in which a main gas stream is cooled and heat is transferred by convection to a liquid and a secondary gas stream across a heat transfer surface. Liquid bearing the heat evaporates into the secondary stream. A total gas stream is subjected to initial cooling along a moisture impervious surface of a heat exchange element to cause dry or sensible cooling. A secondary gas stream is diverted from the total discharge from the dry cooling stage and is directed counterflow to the total stream at the opposite surface of the heat exchange element which is an absorbent surface to cause heating and humidification of the secondary stream. The remaining cooled stream which is the primary stream is subjected to sorbent treatment to heat and dehumidify the same by flowing it through an absorbent media. The primary gas flow is then subjected to a final heat exchange treatment stage similar to the initial heat exchange treatment.

  • Patent number: 5046329
    Abstract: Two versions of a portable air conditioning unit (10, 100) are provided. The larger unit (10) is separable into two halves (12, 14) which contain three cold objects (32, 34, 36) such as freezable gels. A series of aluminum baffles (22-30) define a torturous air flow passage through the unit where air passes over each one of the cold objects sequentially to significantly cool the air flow through the unit. The air flow is generated by a fan (38) which can be powered by batteries, AC power, solar power or the like. The second embodiment of the air conditioning unit (100) can be actually carried by the user with a strap to cool the face of the user.

  • Patent number: 5046551
    Abstract: Disclosed is a long term thermal energy production, storage and reclaim system that benefits the electric utility and its customers by shifting electricity usage from a spiked, high power, direct acting basis operated largely during seasonal peak demand periods to a long term level load at a significantly lower power level. The electricity usage shift is achieved by long term storage of thermal energy generated by a continuously operated low power level prime mover and the use of the stored energy on demand to satisfy the seasonal thermal load. The initial cost of the long term thermal energy production, storage and reclaim system is cost competitive with that of direct acting systems for satisfying the same loads. By using the system, the customer saves significantly on energy charges during the life of the system due to a rate structure that provides favorable rates for customers who do not adversely impact the utility's annual load factor.

  • Patent number: 5044166
    Abstract: A refrigeration process including a refrigeration cycle, and refrigerant purge and recovery operations is disclosed. The refrigeration cycle may be a vapor compression cycle or an absorption cycle, for example. A purge stream is withdrawn from the refrigeration cycle and subjected to treatment by means of a membrane separation unit. The purge-stream treatment operation produces an essentially pure refrigerant stream, suitable for return to the refrigeration cycle, and an air stream, clean enough for direct discharge to the atmosphere. The process is applicable to most refrigerants, but is particularly useful in minimizing atmospheric emissions of chlorofluorocarbons, such as CFC-11 and CFC-12.
