Benefits of technology
The present invention provides an operation control method for a unitary air conditioner that improves the load response capabilities of compressors by operating the compressors in the three-stage operation mode upon driving one or more compressors. This method also improves energy efficiency and amenity by checking the previous operation status of the compressors and determining the operation mode of the compressors based on the previous operation status. The technical effects of this invention include improved load response capabilities and energy efficiency.
Problems solved by technology
Therefore, the conventional unitary air conditioner has the defect of decreasing the load response capabilities of the compressors and of increasing of power consumption by operating the compressors only in the two-stage operation mode.

The present invention discloses an operation control method for a unitary air conditioner. The present invention improves the load response capabilities of compressors by operating them at three-stages of the maximum operation, minimum operation and intermediate operation using one or more compressors, and improves the energy efficiency and the amenity by determining the three-stage operation mode based on the previous operation status.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a unitary air conditioner, and more particularly, to an operation control method for a unitary air conditioner which improves the load response capabilities of compressors and improves energy efficiency and amenity. [0003] 2. Description of the Background Art [0004] Generally, a unitary air conditioning system is a kind of centralized cooling and heating system which creates a hot air or hot air in one place using a cooling and heating system and supplies it to an individual space through a duct. [0005]FIG. 1 is a schematic view illustrating a conventional unitary air conditioner of heat pump type using a cooling cycle. [0006]FIG. 2 is a system view of the conventional unitary air conditioner of FIG. 1. [0007] As shown in FIGS. 1 and 2, the conventional unitary air conditioner comprises one outdoor unit 1 fixedly disposed outside a building, a cold and hot air unit 2 connected to a f...
