Title:
AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/002008
Kind Code:
A1
Abstract:
An air conditioning system according to the present invention includes one or more air conditioner groups (1) and a central control device (100). The air conditioner group (1) has a refrigerant circuit formed by connecting, by pipe, an outdoor unit (10) having a compressor (12), of which the operating frequency can be adjusted as desired, and an indoor unit (20) for air-conditioning of a space to be air-conditioned. The central control device (100) includes: a storage unit (120) for storing, as data, the operating frequency of the compressor (12) included in the outdoor unit (10) in each air conditioner group (1); and a control unit (110) for determining the outdoor unit (10) to be stopped such that the operating frequency of the compressor (12) included in the outdoor unit (10) of the air conditioner group (1) being operated approaches the maximum efficiency, on the basis of the data stored in the storage unit (120), and the relationship between the operating frequency of the compressor (12) included in the outdoor unit (10) in each air conditioner group (1) and the energy efficiency thereof. With the above-mentioned arrangement, since the control unit of the central control device determines the outdoor unit to be stopped, loads on air conditioning can be dispersed, so that a compressor being driven at an operating frequency lower than the operating frequency for the maximum efficiency can be driven at the operating frequency for the maximum efficiency or at an operating frequency close thereto, thereby enabling efficient operation of the entire air conditioning system.
