  • Patent number: 7841206
    Abstract: A refrigerator having a main body includes a refrigerating chamber and a freezing chamber provided for storing foods. A cool air-generating device provided in the body generates cool air and a cool air-supplying device including at least one opening for discharging the cool air, is used to circulate the cool air through the freezing chamber, the refrigerating chamber, and the cool air-generating device. A separator provided adjacent to the opening acts to uniformly diffuse the cool air in the freezing chamber and the refrigerating chamber. The separator acts to separate two flows that are then brought back together. The collision and mixing of the two flows create a turbulent flow of air that is directed into the refrigerating and freezing chambers.

  • Patent number: 7832217
    Abstract: A control system measures the pressure/temperature of the refrigerant within a Thermal Energy Module having a heat exchanger and calculates the thickness of ice within the Thermal Energy Module. A controller calculates an integral starting from the moment when ice accumulation begins: I(t)=?Tr(?)*d? where Tr is the refrigerant saturation temperature changing with time t. The thickness of the ice on one side of the heat exchanger can be calculated using the following formula: X=?(2*I*K*Ui/?i/ci) where Ui is the thermal conductance of ice ?i is the density of the ice Ci is the latent heat of the ice K is a correction coefficient associated with the type of the heat exchanger.

  • Patent number: 7832214
    Abstract: An air-conditioning device includes a pump for sending a thermal medium, a thermoelectric conversion unit for absorbing heat from the thermal medium, a target setting unit for setting a target cooling value, and a controlling unit. The controlling unit increases a flow amount of the thermal medium to be larger than a predetermined amount and stops the thermoelectric conversion unit from absorbing heat, when the target cooling value is smaller than a predetermined value. The controlling unit increases a heat-absorbing amount of the element and keeps the flow amount of the thermal medium to be larger than the predetermined amount, when the target cooling value is equal to or larger than the predetermined value.

  • Patent number: 7827807
    Abstract: Disclosed is a method and device to increase the cooling load that can be provided by a refrigerant-based thermal energy storage and cooling system with an improved arrangement of heat exchangers. This load increase is accomplished by circulating cold water surrounding a block of ice, used as the thermal energy storage medium, through a secondary heat exchanger where it condenses refrigerant vapor returning from a load. The refrigerant is then circulated through a primary heat exchanger within the block of ice where it is further cooled and condensed. This system is known as an internal/external melt system because the thermal energy, stored in the form of ice, is melted internally by a primary heat exchanger and externally by circulating cold water from the periphery of the block through a secondary heat exchanger.

  • Patent number: 7810353
    Abstract: A multi-compressor heat pump system configured to provide heating and cooling over a range of ambient temperatures. The compressors can be operated independently and alone or together in series for maximum output. Heat exchangers are selectively fluidically connected to the compressors to enable refrigerant flow between the compressors and at least two heat exchangers in a manner that enables the heat pump system to be selectively operable in various modes. Preferred aspects include selectively operating the compressors based on the ratio of the evaporating and condensing pressures of the refrigerant within the heat pump system, a mixing chamber between the compressors, and a lubricant management system to prevent the accumulation of a lubricant in one of the compressors.
