20090038325 | Outdoor Unit of Air Conditioner and Its Control Method - An outdoor unit includes an outdoor unit control circuit, an inverter substrate and a compressor. Periodic communication showing the operating condition of the inverter substrate is set from the inverter substrate to the outdoor unit control circuit. Thus, when the communication is performed-normally, the drive of the compressor is changed to a power saving process according to the necessity of the power consumption and the operating condition of the inverter substrate. When the communication is defective, the power-on reset is done to the inverter substrate. | 02-12-2009 |
20090066508 | Electric Device and Method of Normality Determination for Communication Function in Such an Electric Device - A normality determination unit determines that a communication function for an outdoor unit of its own is normal when receiving a signal from one of indoor units, and writes a normality flag into an EEPROM. Further, the normality determination unit determines that it is not asserted that the communication function for the outdoor unit of its own is normal when not receiving a signal from any of the indoor units for a predetermined time period, and deletes the normality flag in the EEPROM. | 03-12-2009 |
20090118867 | Air Conditioner and Address Setting Method in Air Conditioner - A serial number detection portion simultaneously transmits a detection command for requesting a first digit of a serial number to plurality of indoor units, and the serial number detection portion simultaneously transmits a detection command for requesting a second digit immediately preceding the first digit to the indoor units when a response to the detection command is absent. That is, the address setting is performed again from the immediately preceding digit without returning to an initial digit of the serial number, so that the time necessary for the address setting can be shortened. When the address setting is performed again from the immediately preceding digit, the address setting can be performed more securely by changing a method of recognizing the detection command in the indoor units. | 05-07-2009 |
20100036532 | REFRIGERANT CYCLE AND METHOD OF CONTROLLING THE SAME - An object of the present invention is to reduce electrical noise in accordance with the necessity of a countermeasure taken against electrical noise without changing a structure of an expansion valve. In a case where a judgment result as to whether or not the countermeasure against electrical noise is taken is affirmative, a drive timing (interval) of an expansion valve ( | 02-11-2010 |
20100070087 | AIR CONDITIONING SYSTEM - A remote controller includes a display part and an operation part. Since the display part switches plural kinds of specifications to display behavior and setting conditions of an air conditioner, plural kinds of specifications are prepared in the display part. From a central controller a communication part receives a command for air conditioning behavior of an air conditioner and switching of the display specification. The command includes packet for storing information which indicates switching of the display specification. As a result, the central controller can centrally and individually control both the air conditioning behavior of the air conditioner and switching of the display specification in the display part without operating the display part for each of the air conditioners from a distance. | 03-18-2010 |
20100107019 | REMOTE CONTROL UNIT OF AIR CONDITIONING APPARATUS - A remote control unit of an air conditioning apparatus includes a display unit, a cursor-moving member, a confirmation member, and a controller. The display unit displays a menu and a cursor that indicates an item among a plurality of items inside the menu and is moved by the cursor-moving member when operated by a user. The confirmation member is configured to decide that the item is to be executed. The controller controls the display unit in response to the cursor-moving member or confirmation member being operated. The controller positions an item corresponding to a predetermined input at the top of the menu upon receiving the predetermined input. | 04-29-2010 |
20100121492 | AIR-CONDITIONING CONTROLLER - An air-conditioning controller is configured to receive an operation input for an air-conditioning apparatus capable of being set to a plurality of airflow direction settings. The air-conditioning controller includes a switching button, a determination unit and a display unit. The switching button is for switching between the airflow direction settings. The determination unit is configured to determine a currently selected airflow direction setting based on an operation input inputted via the switching button. The display unit is configured to simultaneously display an image and a character corresponding to the airflow direction setting determined to be currently selected by the determination unit. | 05-13-2010 |
20100325570 | AIR CONDITIONING CONTROLLER - An air conditioning controller includes a storage component, a data receiving component configured to receive set numeric data, a display component configured to display data, and a control component. The storage component has stored operation explanation data, relationship explanation data, and setting layout display data stored therein. The stored operation explanation data defines operations of functions executed in the air conditioner. The relationship explanation data defines relationships between explanations of operations of functions and values that are set. The setting display layout data includes setting display region data and explanation display region data. The control component is configured to cause the set numeric data that the data receiving component has received to be displayed in a setting display region while causing the operation explanation data and the relationship explanation data to be displayed in an explanation display region in accordance with the setting display layout data. | 12-23-2010 |
20100325580 | REMOTE CONTROL UNIT OF AIR CONDITIONING APPARATUS - A remote control unit of an air conditioning apparatus includes a display unit, a cursor-moving member, a confirmation member, and a controller. The display unit displays a menu and a cursor that indicates an item among a plurality of items inside the menu and is moved by the cursor-moving member when operated by a user. The confirmation member is configured to decide that the item is to be executed. The controller controls the display unit in response to the cursor-moving member or confirmation member being operated, and stores screen display modes displayed on the display unit. Upon receiving a predetermined input from the confirmation member, the controller causes items allowing selection of the display modes to be displayed on the menu. | 12-23-2010 |
