A refrigeration system of a household appliance including a compressor, a drip pan configured to collect evaporator condensate, and a pre-condenser. The pre-condenser includes a coil extending from the compressor and having a deformable section and a nondeformable section, wherein the deformable section is disposed between the drip pan and the compressor, and at least a portion of the nondeformable section is disposed in the drip pan such that heat from the coil aids in evaporation of the condensate.

This refrigeration device is provided with: an evaporator configuring a refrigeration circuit; a cascade condenser configuring the refrigeration circuit; and a thermal insulation board arranged between the evaporator and the cascade condenser.

Cold storage unit apparatuses designed for high energy efficiency are provided, which may include: a refrigeration system; a box enclosing an interior space, the box formed by a plurality of insulated sides; an entry into the interior space including a plurality of openable barriers facilitating preventing entry of heat or moisture into the interior space; and a power system connected to the refrigeration system, the power system facilitating independent operation of the refrigeration system when not connected to a power grid, and further facilitating a net energy use of zero from a power grid when connected to a power grid. Cold storage units may further include systems for using the refrigerant of the refrigeration system to defrost one or more components of the cold storage unit, and for using the refrigerant to facilitate maintaining a desired internal temperature of the interior space of the cold storage unit.

The present disclosure relates to a storehouse. In one aspect of the present disclosure, a storehouse may include a first storage space configured to provide a space in which goods are stored within a predetermined temperature or a predetermined temperature range and a second storage space configured to provide a space in which a first heat exchanger is accommodated. The storehouse may include a third storage space configured to provide a space in which a second heat exchanger is accommodated.

A refrigeration appliance includes a refrigeration circuit having a condenser and a heat circulation system for heating an element of the refrigeration appliance. The heat circulation system includes a heat conducting region. A heat exchanging element includes the condenser and the heat conducting region. The condenser and the heat conducting region in the heat exchanger element are thermally coupled in order to output heat from the refrigeration circuit to the heat conducting region of the heat circulation system.

A preferred embodiment utilizes the waste heat from a refrigerant cycle to aid in the removal of condensate from a refrigerated case used primarily by grocery stores. Certain embodiments use a heating element to boil off condensate or a pump to remove the condensate. Another embodiment utilizes a wicking element and a shroud that directs hot air from the condenser through the wick thereby increasing the condensate evaporation rate. Yet another embodiment utilizes the hot gas tube from the refrigeration system routed through the bottom of the condensate tray to pre-heat the condensate to accelerate evaporation. Alternative embodiments combine certain features to create even more efficient system such as a heating element used with the wick system or the hot gas system used with the wick system. In some embodiments, a mold and mildew inhibitor is added to the condensate to maintain cleanliness.

The present invention relates to a refrigerator and/or freezer with at least one body and with at least one cooled interior space arranged in the body, wherein the appliance includes at least one refrigerant circuit that serves for cooling the interior space, wherein the refrigerant circuit includes at least one condenser, wherein at least one heat pipe is provided that is in direct or indirect thermal contact with the condenser and that is arranged such that it forms at least a part of a frame heater of the appliance and/or is in thermal contact with the outer skin of the appliance.

A refrigerator and an anti-condensation method for the refrigerator. The refrigerator includes a first storage compartment, a second storage compartment adjacent the first storage compartment, a separation wall separating the first storage compartment and the second storage compartment, and a heater in the separation wall. The first storage compartment is adapted to be set at a refrigerating temperature, and the second storage compartment is adapted to be set at a freezing temperature. In the anti-condensation method, the heater is controlled to work in an anti-condensation mode when a refrigeration system stops cooling the first storage compartment, to heat a surface of the separation wall facing the first storage compartment, which can significantly reduce the probability of condensation on the surface and is beneficial to reduce the impact of the working of the heater on the refrigeration system.
