Title:
【発明の名称】空気調和装置の運転制御装置
Document Type and Number:
Japanese Patent JP2531264
Kind Code:
B2
Abstract:
PURPOSE:To contrive enlargement of a capacity regulation possibility range correspondent with the decrease of a load by allowing the operation controller to perform drooping control reducing an invertor frequency when the load of a room heat exchanger is reduced to be at equal to or less than a set value while permitting the operation controller to perform a gas bypass and further allowing the operation controller to reduce an air flow of an outdoor fan when the load thereof is equal to or less than a set value. CONSTITUTION:When the loads of room indoor heat exchangers 7a-7c are equal to or less than a set value during operation of a device with the use of an operation control means 51, the output frequency of an invertor 18 is allowed to perform drooping control down to lower limit capable of control with the use of a frequency decrease means 52 and a closing means 17 of a bypass passage 9a is allowed to open with the use of a circulation flow reduce means 54 to make it a gas bypass to reduce the refrigerant circulation flow of a refrigerant circuit 12 so as to perform capacity regulation when the load thereof is not increase more than the set value. When the load thereof is equal to or less than the set value, the air flow of an outdoor fan 3a is changed to the side of a flow air low with the use of an air flow reduce means 53 to correspond to the load so as to make possible the single operation of the indoor heat exchangers.
