Abstract:
The present invention refers to a cooling and/or freezing apparatus, particularly to a cooling apparatus having at least two compartments that can be closed with one door only, and a cooling system comprising at least one compressor, at least one condenser, at least one evaporator, at least one blower for circulating air in said compartments, and at least one means for regulation of refrigerant flow. Spaced from a rear side (5) of said apparatus there is arranged a vertical partition wall (6) extending through said compartments (2, 3). Evaporators (8, 9) are arranged vertically with regard to said apparatus, one above the other, in a spacing (7) between said rear side (5) and said wall (6). Each compartment (2, 3) is provided with at least one shelf (10, 12) and/or at least one pull-out drawer (11) to receive and store goods.
Abstract:
Disclosed is a method and device for a thermal energy storage liquid-suction heat exchanger (TES-LSHX) for air conditioning and refrigeration (AC/R) applications. The disclosed embodiments allow energy to be stored and aggregated over one period of time, and dispatched at a later period of time, to improve AC/R system efficiency during desired conditions. Not only are the benefits of LSHX stored and aggregated for later use, but when dispatched, the discharge rate can exceed the charge rate thereby further enhancing the benefit of demand reduction to utilities. The disclosed embodiments allow great flexibility and can be incorporated into original equipment manufacturer AC/R system designs, and/or bundled with condensing units or evaporator coils. These TES-LSHX systems can be retrofit with existing systems by installing the product at any point along the existing AC/R system's line set.
Abstract:
The present invention relates to a method for controlling a refrigerator in which unnecessary operation of a compressor is prevented for saving power consumption of the refrigerator. The refrigerator includes a compressor, a refrigerating chamber evaporator and a freezing chamber evaporator connected to the compressor, a refrigerant valve (30) for guiding refrigerant to the refrigerating chamber evaporator or the freezing chamber evaporator, and a control unit for controlling the refrigerant valve (30) such that the refrigerant valve (30) blocks or introduces the refrigerant to cause an inside pressure of the freezing chamber evaporator to be elevated higher than an inside pressure of the refrigerating chamber evaporator during evaporation at the refrigerating chamber evaporator for the compressor to draw in the refrigerant remained in the freezing chamber evaporator which did not evaporate.
Abstract:
Kälteanlage zur Kühlung des Innenraumes eines mobilen Kühlraumes, zum Beispiel eines Kühlcontainers, mit 2 drehzahlgeregelten Verdichtern, die über je eine steuerbare Bypassleitung pro Verdichter und eine Steuerbare Ventileinrichtung zwischen Druck- und Saugseite von zwei Verdichtern Verdichters parallel einstufig oder hintereinander zweistufig betrieben werden könrien. Die Ventileinrichtungen erhalten Signale aus einer Steuerung mit AlgoritHmen in die Nutz- und Umgebungstemperatur als Soll- beziehungsweise Messwert eingehen. Aus dem Anforderungsprofil der Containerkühlung resultieren die energieeffizientesten Betriebsarten und die Drehzahlen der Verdichter.

Abstract:
A refrigerated transport system includes a prioritizing algorithm to limit the maximum amount of refrigerant flow available to at least one limited cooling compartment by holding a delta T (difference between the supply air temperature and return air temperature) instead of a setpoint temperature in the at least one limited cooling compartment when the available cooling capacity is insufficient to hold a substantially constant temperature in all compartments. A method for creating multiple refrigerated compartment spaces having precision temperature control includes the steps of: prioritizing the compartments by identifying at least one priority compartment to be held at a setpoint temperature; and limiting refrigerant flow to all but the priority compartment when there is insufficient cooling capacity to maintain all compartments at their respective setpoint temperatures.
Abstract:
A comb-like insert having a body and plurality of tapered fingers is installed with its fingers disposed within respective minichannels. The fingers and their respective minichannels are so sized as to restrict the channels and frictionally hold the insert in place in one dimension while providing for gaps in another dimension such that the flow of refrigerant is somewhat obstructed but allowed to pass through the gaps between the insert fingers and the minichannel walls and then expand as it passes along the tapered fingers to thereby provide a more homogenous mixture to the individual minichannels. A provision is also made to hold the insert in its installed position by way of internal structure within the inlet manifold. In one embodiment, an internal plate is provided for that purpose, and the plate has openings formed therein for the equalization of pressure on either side thereof.
Abstract:
An apparatus for controlling the temperature of an electronic device. The apparatus comprises a refrigeration system including a compressor and a multi-pass heat exchanger. The refrigeration system is operative to circulate a refrigerant fluid through a fluid flow loop such that the refrigerant fluid will change between gaseous and liquid states to alternately absorb and release thermal energy. The refrigerant fluid is pre-cooled in the heat exchanger by a pre-cooling refrigerant stream. A thermal head is connected into the fluid flow loop and has a temperature controlled surface.
Abstract:
A compressor assembly, including a compressor, at least one pipe having ends and an intermediate portion between the ends, the at least one pipe being connected to the compressor at the ends, and at least one support member for supporting the intermediate portion of the at least one pipe relative to the compressor.
