Abstract: A fuel cell power generation system includes a fuel cell generating electric power with a fuel, a condenser extracting mixed gas of hydrogen and carbon dioxide contained in water vapor discharged from the fuel cell, a component separator separating the hydrogen and the carbon dioxide from the mixed gas extracted by the condenser, a hydrogen supply path supplying the hydrogen separated by the component separator to the fuel cell, and a carbon dioxide liquefier liquefying the carbon dioxide separated by the component separator.

Abstract: A pallet for the cold storage or transportation of goods consists virtually of a single framework molded from a plastics material, and having a hollow interior filled with a refrigerant without the aid of any bag.

Abstract: A method for storing horticultural plants and an apparatus therefor are disclosed. The method of the present invention comprises placing the live horticultural plants in a container for transportation, wherein the temperature and the humidity in the container are kept at conditions suited for the horticultural plants within the range of 10.degree.-25.degree. C. and 60-90% RH, volatile gas generated by the horticultural plants are removed, the air inside the container is circulated, and the horticultural plants are irradiated with a light mainly composed of red light and blue light.

Abstract: The low temperature food storage equipment of the present invention is provided with an icehouse and a food storeroom each surrounded by a heat insulator. The icehouse and the storeroom are connected by a detachable heat exchanger disposed therebetween. In the icehouse there is stored water which is frozen into ice when the outside air grows cold. In the storeroom there are kept in cold storage a large amount of shippable food, for example, potatoes. In the case of shipping the food, the heat exchanger is removed and the food is transported on a truck or the like while being kept in cold storage in the storeroom.

Abstract: A ventilation apparatus for a container for transporting goods by truck or ship. The walls of the container are provided with an inlet opening and an outlet opening, and an inlet unit is connected to the inlet opening and an outlet unit is connected to the outlet opening. The outlet unit is provided with a battery-operated fan for a forced ventilation of the container, temperature sensors are provided for detecting the inner wall temperature and inner air temperature, and a degree of change in the wall temperature per unit of time is calculated for operating the fan when the degree of change in the wall temperature is larger than a predetermined value. Furthermore, the difference between the inner air temperature and the wall temperature is calculated, and the fan is operated when that difference is larger than a predetermined value.

Abstract: A refrigerating and humidity-regulating system for a container is disclosed, which comprises a refrigerating unit having a humidity-regulating apparatus assembled therein. This humidity-regulating apparatus includes a solid adsorptive material, an air heater, an air blowing means, and an air circulation route for circulating inside and outside air through the air heater and the solid adsorptive material, in that sequence. The solid adsorptive material may be formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed. In one preferred embodiment, the above-mentioned humidity-regulating apparatus is assembled in multiple in the refrigerating unit, wherein in each of the humidity-regulating apparatuses the solid adsorptive material is formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed in each humidity-regulating apparatus.

Abstract: A refrigeration apparatus including a hot gas bypass pipe provided in a refrigeration circuit is constructed by connecting a compressor, a condenser, an expansion valve and an evaporator, a humidifier for humidifying the inside of a chamber, a heat exchanger located between a feed pipe for supplying water to said humidifier and said hot gas bypass pipe. This apparatus prevents freezing of water inside the pipes.
