Benefits of technology

[0020] Therefore, an object of the present invention is to provide a driving controlling apparatus for an air conditioner having a plurality of compressors capable of preventing increase of consumption power and decrease of a driving efficiency of a system due to an excessive refrigerant amount even if the compressors of the air conditioner having a maximum refrigerant amount are driven in a minimum capacity driving mode, in which a refrigerant cooled by an expansion is partially heat-exchanged by a condensing unit thus to lower a condensation temperature, and a method thereof.

Problems solved by technology

However, when the system is driven in a minimum capacity driving mode (driving of only one compressor), the refrigerant amount to be introduced into the compressor having a capacity of 100% increases a consumption power due to an excessive refrigerant amount thereby to lower a driving efficiency of the system.

Abstract

A driving controlling apparatus for an air conditioner having a plurality of compressors, and a method thereof. The apparatus comprises a flow amount distribution resistor installed at an outlet of an expansion valve, for passing a certain amount of refrigerant; and a controlling unit for detecting a current load and outputting a control signal so as to introduce a certain amount of refrigerant into the flow amount distribution resistor based on a driving mode corresponding to the detected load.

Description

RELATED APPLICATION [0001] The present disclosure relates to subject matter contained in priority Korean Application No. 10-2005-0073499, filed on Aug. 10, 2005, which is herein expressly incorporated by reference in its entirely. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a driving controlling apparatus for an air conditioner having a plurality of compressors, and a method thereof, and more particularly, to a driving controlling apparatus for an air conditioner having a is plurality of compressors capable of preventing increase of consumption power and decrease of a driving efficiency of a system due to an excessive refrigerant flow, and a method thereof. [0004] 2. Description of the Background Art [0005] Generally, an air conditioner serves to lower an indoor temperature by using a refrigerating cycle of a refrigerant compressed into a high temperature and a high pressure by a compressor. [0006] When the air conditioner is ...
