Problems solved by technology

[0009] However, if the above-mentioned conventional air conditioner is used in a building such as a large building, the capacity that must be provided by the variable capacity compressor will inevitably become large
It is difficult to manufacture such high-capacity compressors, such as variable-capacity compressors, as stand-alone units
Moreover, even if it can be manufactured as a stand-alone unit, the cost of this high-capacity compressor is very expensive, thereby causing an economic burden due to an increase in the cost of the compressor

Embodiment Construction

[0025] The present invention will now be described in detail with reference to its preferred embodiment, examples of which are shown in the accompanying drawings, wherein like reference numerals indicate like elements.

[0026] Figure 3A and 3B A structure of an air conditioner according to an embodiment of the present invention is shown in which an inverter type compressor and a two-stage variable capacity compressor are connected in parallel to each other. like Figure 3A As shown, the air conditioning device of the present invention comprises two compressors 30 and 40 connected in parallel to each other. Compressors 30 and 40 may be used in multi-unit air conditioning installations in which multiple indoor units 90 are connected to one outdoor unit 80 (see Figure 3B ). The illustrated compressors 30 and 40 are installed in an outdoor unit 80 and their capacities are controlled by the outdoor unit microcomputer 60 .

[0027] The outdoor unit microcomputer 60 controls ...

Abstract

An air conditioning apparatus and control method thereof includes an inverter-type compressor and a two-stage variable-capacity compressor connected in parallel with their respective capacities controlled according to indoor air conditioning loads. Thus, the present invention is cost-competitive due to a capacity of the inverter-type compressor being lower than that of the two-stage variable-capacity compressor.

Description

[0001] Refer to related documents [0002] This application claims priority from Korean Patent Application No. 2002-33221 filed in the Korean Intellectual Property Office on June 14, 2002, the disclosure of which will be incorporated herein by reference. technical field [0003] The present invention relates to an air conditioner having an inverter-type compressor and a two-stage variable capacity compressor and a control method thereof. Background technique [0004] Generally, a single air conditioner having an indoor unit and an outdoor unit connected to each other does not have a large indoor air conditioning load (required capacity), so in the single air conditioner, a fixed capacity compressor is installed on the outdoor unit. [0005] On the contrary, a multi-unit air-conditioning device having a plurality of indoor units connected to one outdoor unit is designed so that each indoor unit can independently provide an air-conditioning load for a corresponding indoor spac...
