Problems solved by technology

[0010] However, if a building such as a large building adopts a conventional air conditioning unit, the capacity that must be provided by the variable capacity compressor will inevitably become larger
Moreover, it is difficult and expensive to produce such a high-capacity compressor as a stand-alone unit, and even if a stand-alone unit could be produced, it would cause an economic burden due to an increase in the cost of the compressor

Embodiment Construction

[0026] Preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, examples of which are shown in the accompanying drawings, wherein like reference numerals indicate like elements. Hereinafter, in order to disclose the present invention, embodiments will be described with reference to the drawings.

[0027] image 3 is a view showing the structure of an air conditioner according to an embodiment of the present invention, in which two-stage variable capacity compressors are connected to each other in parallel.

[0028] Such as image 3 As shown, the air conditioning device comprises two compressors 30 and 40 connected in parallel to each other. Such as Figure 7 As shown, compressors 30 and 40 may be used in a multi-unit air conditioning installation in which multiple indoor units 60 are connected to one outdoor unit 80 . At this time, the compressors 30 and 40 are installed in the outdoor unit 80, and the capaci...

Abstract

Provided are an air conditioner and a control method thereof, wherein two-stage variable capacity compressors are connected in parallel to each other, thereby controlling capacities of the two-stage variable capacity compressors according to indoor air-conditioning loads. The use of a pair of two-stage variable capacity compressors in an air-conditioning unit reduces costs and achieves the effect that the control of the two two-stage variable capacity compressors The linear control is the same as that of a large variable capacity compressor of the same capacity.

Description

[0001] Refer to related documents [0002] This application claims the priority of Korean Patent Application No. 2002-33223 filed in the Korean Intellectual Property Office on June 14, 2002, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to an air conditioner and its control method, wherein two stages of variable capacity compressors are connected to each other in parallel. 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 a fixed-capacity compressor is installed in the outdoor unit. [0005] On the contrary, a multi-unit air-conditioning device with multiple indoor units connected to one outdoor unit is designed so that each indoor unit can independently solve the air-conditioning load of the corresponding indoor space. In this multi-unit air-conditio...
