Abstract: A container refrigeration apparatus includes: a casing which forms an external storage space communicating with the exterior of the container and an internal storage space communicating with the interior of the container; a refrigerant circuit; an external fan; an internal fan; and an inside air control system including an exhaust passage which allows a space on a blowout side of the internal fan in the internal storage space to communicate with the external storage space, and controls composition of the inside air in the container. An external end of the exhaust passage is open on a suction side of the external fan in the external storage space.

Abstract: A refrigerator may include a refrigerator cabinet and at least one compartment disposed within the refrigerator cabinet, an ice maker for making wet ice disposed within the refrigerator cabinet, a bucket for storing the ice, the bucket positioned to receive the wet ice from the ice maker, and a drain in the bucket for draining water from the bucket. A method of making ice in a refrigerator includes making ice using an ice maker of the refrigerator, conveying the ice from the ice maker to a bucket having a drain, maintaining the ice in the bucket at a temperature above freezing to allow the ice to melt to water, and draining the water from the bucket.

Abstract: The present invention discloses an improved air conditioning system which can supply fresh air prepared separately. A first preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit installed in a ceiling, and means connected to the indoor unit for supplying fresh air stored separately to the indoor unit. A second preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit, air supply and air discharge ducts, and means connected to the air supply duct for supplying fresh air stored separately to the indoor unit. In the second embodiment, the indoor unit includes a fan, an indoor heat exchanger, and a guide duct for guiding flow passages of the external air and room air, and, if necessary, further including a preheat exchanger arranged to surround the guide duct for indirect heat exchange between the external air and the indoor air.

Abstract: A portable cooling or heating system suitable for use on a vehicle such as a car, plane or boat, that does not have its own air conditioning system. The system is intended to be combined with a portable cooler chest and includes an electric fan unit that can be powered from the power supply on a vehicle. The cooling is provided by ice and the like. The system can also be used to heat a confined space by placing a hot material in the chest.

Abstract: A portable air conditioner/beverage container includes a container having top and bottom ends, a side wall, an air intake opening, and a cool air outlet. Within the container, there is a separation wall. A first space between the separation wall and the side wall defines an air intake region. The air intake region is in fluid communication with the air intake opening. A second space between the side wall and the separation wall defines a cold substance chamber. A blower is in fluid communication with the cool air outlet. A power supply is coupled to the blower. The blower pulls air in through the air intake opening, down through the air intake region, and around the separation wall. Air flows up through the cold substance chamber, through the cool air outlet, where it is expelled onto a user.
