Abstract: A refrigerator with at least one openable door has a hinge at a pivoting edge of the door allowing the door to open about the pivoting edge. A water dispenser, positioned on the door, has a paddle which is moved horizontally by a user to cause water to be dispensed.

As the refrigerant gas passes through the exhaust manifold, it is superheated by the surrounding hot exhaust gases thereby increasing the refrigerant gas pressure to reduce the amount of work done by the compressor.

Abstract: A ground-based system and method of supplying electrical power and temperature-controlled air to an aircraft environmental control system during ground support operations uses a throttle valve to control the flow of compressed air flowing through a heat exchanger. An air conditioner module mounted on a wheeled cart removes heat from the compressed air that is supplied to it from an auxiliary power unit (APU), and supplies cooled compressed air at a desired temperature. The temperature of the cooled compressed air is controlled by selectively positioning a throttle valve, which regulates compressed air flow from the compressed air source. The throttle valve position is controlled in response to one or more ambient meteorological conditions and/or the amount of electrical power being supplied from the system.
