Abstract:
A heat pump system includes a refrigerant circuit, at least one compressor, an evaporator, and a controller programmed to defrost the evaporator in a defrost mode, wherein in the defrost mode the controller is programmed to monitor the evaporator to detect frost creation thereon, and reduce the speed of the at least one compressor and/or reduce the number of some, but not all operating compressors of the at least one compressor, if frost creation is detected on the evaporator. In some embodiments, the controller is programmed to defrost the evaporator in a second defrost mode. In the second defrost mode the controller is programmed to monitor the evaporator to detect frost creation thereon, turn off the at least one compressor when frost is detected on the evaporator, and operate a fan to force ambient air over the evaporator to defrost the evaporator.
Abstract:
Un système de détection du givre sur une surface (18), comprend un élément résistif (12) au contact de la surface (18), un générateur de courant (22) connecté à l'élément résistif (12), un capteur (28) mesurant la température de l'élément résistif (12), et une unité de calcul (38) apte à déterminer la présence de glace sur la surface (18) en fonction de la mesure délivrée par le capteur. Le générateur (22) injecte un courant électrique dans l'élément (12) pour porter celui-ci à une température supérieure à celle de la fusion de la glace. L'unité de calcul (38) détermine un écart entre la température mesurée pendant le chauffage de l'élément et une fonction de croissance exponentielle, et détecte du givre sur la surface (18) si l'écart est supérieur à un seuil de détection prédéterminé.
Abstract:
A system, apparatus, and method for determining when an amount of ice formed on an evaporator or evaporator grid has reached a predetermined size are illustrated. An acoustic transmitter an acoustic transmitter positioned proximate to the evaporator channels acoustic signals emanating from the evaporator or evaporator grid to an acoustic sensor, which generates an electronic signal indicative of the acoustic signal. A receiver module coupled to the acoustic sensor is configured to receive the electronic signal and determine that ice formed on the evaporator has reached a predetermined size based on the electronic signal.
Abstract:
The present invention relates to a control method of a refrigerator which operates a cooling cycle including two storage compartments, a compressor, a condenser, a valve, fans, and evaporators for cooling the respective storage compartments, with one of the fans corresponding to the storage compartment for storing items at relatively low temperatures being activated for a set amount of time even after the compressor is deactivated at the completion of cooling of the storage compartment for storing items at relatively low temperatures. In a refrigerator comprising a first storage compartment for storing an item, a second storage compartment for storing an item at a lower temperature than the first storage compartment, a cooling cycle including a compressor, a condenser for condensing a refrigerant from the compressor, a valve for directing the refrigerant from the condenser to first and second evaporators, with the first and second evaporators evaporating supplied refrigerants to cool the first and second storage compartments, respectively, and first and second fans for circulating cool air from the first and second evaporators, respectively, and a controller for controlling the first and second fans, the valve and the compressor, a control method of the refrigerator comprising: a first step of the controller activating the compressor if cooling of the second storage compartment is required and activating the second fan; and a second step of the controller deactivating the operation of the compressor, if the cooling of the second storage compartment is completed, and deactivating the operation of the second fan after the operation of the compressor is deactivated.
