  • Publication number: 20150096318
    Abstract: An indoor unit of an air-conditioning apparatus includes a controller that controls a refrigeration cycle, an up/down air flow direction plate, and a left/right air flow direction plate, based on information of a person whose image is captured by an imaging device. When the refrigeration cycle is stopped, in a case where the face of the person detected by the imaging device remains stationarily facing the imaging device for a preset recognition time, the controller recognizes the person as one wishing the refrigeration cycle to be activated, and activates the refrigeration cycle.

  • Patent number: 8997517
    Abstract: A storage compartment assembly is located within the interior of a compartment of a refrigerator such as a fresh food compartment of a refrigerator. The storage compartment assembly includes a storage container the temperature of which can be controlled independently of the temperature in the fresh food compartment. At least one of the sides of the storage container can be spaced away from a respective interior side of the refrigerator compartment and a housing located in the space between the side of the storage container and the interior side of the refrigerator compartment. The housing can contain components that are configured to function in the operation of the refrigerator, including the storage compartment assembly. The refrigerator can comprise a bottom-mount refrigerator and the fresh food compartment can be provided with double-doors for closing and opening the interior of the fresh food compartment.

  • Patent number: 8997515
    Abstract: An auxiliary device is tended and adapted to be accommodated in an air conduit forming part of an air conditioning device, to which air conduit first flow components, such as a fan, are connected for the purpose of bringing about a main airflow through the air conduit such that the whole main airflow flows through the auxiliary device. The auxiliary device has an arrangement of a number of air conditioning modules which in an active state of the relevant air conditioning module, each allow passage of a partial flow of the airflow and together allow passage of the whole main flow. Control components adjust each of the air conditioning modules between an active state, in which passage of the relevant partial flow is allowed, and a passive state in which a partial flow substantially amounts to zero or flows in opposite direction.

  • Publication number: 20150068226
    Abstract: An apparatus and method for controlling the heating of an airflow. According to certain embodiments, the temperature of an outdoor heat exchanger and the speed of a compressor are used to determine a blower speed for a variable speed indoor air blower. The selected blower speed may facilitate a flow of air across a second, indoor heat exchanger at an indoor volumetric flow rate that heats the airflow to a leaving air temperature. The leaving air temperature may at least seek to attain the temperature of a variable target leaving air temperature that is adjusted based on changes in outdoor ambient temperatures. Additionally, according to certain embodiments, the blower speed may be based on an indoor volumetric airflow rate that is determined, at least in part, on a determined system heating capacity and a temperature at the outdoor heat exchanger.

  • Patent number: 8973383
    Abstract: A humidity control apparatus has a humidity control apparatus having a humidifying part for humidifying air and a dehumidifying part for dehumidifying to control humidity of a humidity control space. The dehumidifying part has: a main body part that is configured to encapsulate a working fluid therein and to cause a heat-pipe phenomenon. A heat-insulating part fits externally to the main body part and a heat absorption part absorbs heat from a base side part located on one side of the main body part in relation to the heat-insulating part and thereby condenses the working fluid that evaporated into gas in a front side part located on the other side of the main body part in relation to the heat-insulating part. The dehumidifying part dehumidifies the air by means of the front side part of the main body part where the working fluid in liquid form evaporates.
