Abstract:
A refrigerator that is capable cf achieving smooth flow of cool air therein and improving cooling efficiency of a cooled evaporator and a control method of the same that is capable of controlling operation time of an evaporator and a fan, thereby improving cooling efficiency of the refrigerator are disclosed.
Abstract:
Die Erfindung geht aus von einem Kältegerät (1) mit einem Innenraum der in wenigstens zwei Kältezonen (3, 4) unterteilt ist, wobei jede Kältezone (3, 4) durch einen Verdampfer (5, 6) gekühlt wird und wobei wenigstens zwei Verdichter (7, 8) für die Versorgung der Verdampfer (5, 6) mit einem Kältemittel vorgesehen sind, mit einer Steuerung (2) zum Betreiben der Verdichter (7, 8). Erfindungsgemäß ist die Steuerung (2) in Abhängigkeit von vorbestimmten Bedingungen in unterschiedlichen Arbeitsmoden betreibbar. Es ist ein Normalmodus vorgesehen, in dem die wenigstens zwei Verdichter (7, 8) ausschließlich zeitlich getrennt betrieben werden.
Abstract:
Disclosed is an apparatus and a method for controlling a driving of a fan motor for a refrigerator. In a normal driving mode that a temperature of the inside of the refrigerator is higher than a predetermined temperature, the fan motor is driven in a normal speed, and in a waiting mode that the temperature of the inside of the refrigerator is lower than the predetermined temperature, the fan motor is driven in a driving speed very lower than that of the normal driving mode, without stopping of the fan motor, accordingly it is capable of preventing moisture introduced into the fan motor from being frozen, thereby preventing the fan motor from being locked.
Abstract:
Eine Kältemaschine für ein Haushalts-Kältegerät umfasst einen Verdichter (1), einen Verflüssiger (2) und einen Verdampfer (5), die in einem Kältemittelkreislauf verbunden sind. In einem Kältemittelweg vom Verflüssiger (2) zum Verdampfer (5) ist ein Stoppventil (3) angeordnet.
Abstract:
A refrigerant system is provided with tandem compressors. As is known, tandem compressors operate in parallel to provide a refrigerant system designer with the ability to achieve a stepped capacity control of the refrigerant system. At least one of the tandem compressors is provided with a variable speed drive. Further, at least one of the tandem compressors may be provided with the economizer and/or unloader functions. System configurations with multiple compression stages and multiple injection ports are disclosed. In this manner, the stepless capacity control can be achieved.
Abstract:
A control system (12) for controlling a refrigeration system (17) comprising two or more compressors (13a, 13b) (e.g. a twin compressor system) . Each compressor (13a, 13b) is connected to an electronic unit (14a, 14b) , and the electronic units (14a, 14b) are adapted to communicate appropriate signals to each other when the corresponding compressor (13a, 13b) starts or stops operation. The electronics units (14a, 14b) are further adapted to control the operation of the corresponding compressor (13a, 13b) in response to a signal received from the other electronic unit (14a, 14b) . Thereby the control system (12) is adapted to control the operation of the two or more compressors (13a, 13b) in a mutually dependent manner.
Abstract:
A method and device for controlling the inside temperature of a refrigeration compartment, wherein control means are controlled by a thermostat; a temperature sensor is located far away from the refrigerating means and in a specific portion of the inside volume of the refrigeration compartment, e.g. on a lighting fixture; and the specific portion of the inside volume of the refrigeration compartment is selected with the exclusion of a first top portion of the volume of the refrigeration compartment having a volume equal to 8-10% of the total inside volume of the refrigeration compartment, with the exclusion of a second front portion of a depth equal to at least 10% of the total inside depth of the refrigeration compartment, and preferably also with the exclusion of a bottom portion of the refrigeration compartment.
Abstract:
A method of operating a water chiller (10) having a water tank (12), a cold water tap, and a condenser and fan (18). The chiller avoids freezing of the water in the tank (l2) by switching between `normal' and `protection' operating modes. The switching is initially triggered by checking the length of time since the cold water tap was last operated.
