Abstract: The liquid galley refrigeration system for cooling food carts for aircraft employs an intermediate working fluid to transfer heat from one or more food carts to one or more remote chillers, allowing the carts and chillers to be advantageously distributed in the aircraft. While the chiller working fluid undergoes a phase change in order to transfer heat from the intermediate working fluid to the cooling air, the intermediate working fluid remains in its liquid phase throughout its circulation. A recirculation pump circulates the intermediate working fluid through a distribution system that may link a plurality of chillers to a plurality of food carts, and the temperature of the food carts is regulated by a combination of controls.

Abstract: A thermally actuated valve employs a plunger and bore valve configuration. A thermally expansible wax actuator has an axial length that changes in response to the temperature in a cavity of the valve. At temperatures above a predetermined set point, the actuator produces axial force sufficient to extend the length of the actuator against a return bias and project the plunger and seal into the bore, closing the valve. The plunger defines a pressure relief fluid flow path from the valve cavity to the valve outlet. A pressure relief valve is arranged in the plunger and is responsive to pressure in the valve. The pressure relief valve opens to relieve pressure above a pre-determined level. The thermally actuated valve and the pressure relief valve are coaxial and employ a common outlet.

Abstract: A heating/cooling system includes a closed circuit refrigeration system including an evaporator. Water circulating through a closed water circuit exchanges heat with refrigerant in the evaporator, cooling the water for a cooling application. The water can also be heated by a boiler, and the heated water is used to heat a space. A water pump flows the water through the water circuit. When a current sensing relay detects a power failure, a boiler control algorithm is initiated to “trick” a motor of the compressor into believing the heating/cooling system is operating in a heating mode. Therefore, a compressor failure alarm is not generated. The water pump is powered by a battery pack during the power failure. Water continues to flow through the water circuit, preventing the water from freezing.

Abstract: An ice level detection device of a refrigerator includes an ice level detection arm and an ice storage container detection arm, the ice level detection arm operatively connected to a mechanical motor for movement between an ice sensing position with the ice level detection arm extending at least partially into the ice storage container and an ice harvest position with the ice level detection arm being clear of the ice storage container, the ice storage container detection arm abutting the ice storage container while the ice storage container is mounted at the door. The ice level detection arm transitions from the ice sensing position to the ice harvest position for ice harvest by the ice maker. Opening the door disables ice harvest by the ice maker. Upon removal of the ice storage container the ice level detection arm transitions to the ice harvest position and disables ice harvest.

Abstract: A thermostatic valve control structure mainly has an axial movement element movable axially to control opening size of a hot water inlet and a cold water inlet. The axial movement element has a ceramic layer which has a smooth surface to reduce friction with a sealing ring. The ceramic layer provides advantages of resisting acid and alkali, less likely to accumulate water dregs, simpler structure and longer life span. Thus the total life span and durability of the thermostatic valve control structure can be enhanced.

Abstract: A refrigerant system is provided with a suction pulse width modulation valve, and a pulse width modulation control for controlling this valve. System pressures, such as the pressure on the evaporator and the condenser are monitored. The measured system pressures are maintained within a band of acceptable lower and upper limits. As the pulse width modulation control cycles the valve, the refrigerant pressures in the evaporator and the condenser tend to fluctuate. The control ensures those fluctuations are within the limits by controlling the duty cycle of the valve.
