Problems solved by technology

[0005] At present, most air-conditioning systems use the above method to increase the unit cooling capacity and cooling coefficient. However, when the multi-connected air-conditioning system has multiple outdoor units, each outdoor unit needs to be independently equipped with a subcooler, expansion valve and corresponding piping, which increases the cost

Abstract

The invention provides a multi-split air conditioning system. The multi-split air conditioning system comprises an indoor unit, multiple outdoor units and super-cooling devices, wherein the multiple outdoor units are communicated with the indoor unit through pipelines after being connected in parallel, the super-cooling devices are detachably arranged on the pipelines, and the super-cooling devices are communicated with the indoor unit and the multiple outdoor units which are connected in parallel. The multi-split air conditioning system provided by the invention is provided with the multiple outdoor units which are connected in parallel, the super-cooling devices are detachably arranged on the pipelines, whether the super-cooling devices need to be arranged or not can be selected by a user according to self needs, and the super-cooling devices can be arranged in any positions on the pipelines; compared with a mode of arranging the super-cooling devices in the outdoor units in the prior art, the super-cooling devices are detachably arranged on the pipelines, on one hand, the using amount of the super-cooling devices is effectively reduced, the problem of resource waste is avoided, and thus the production cost of the multi-split air conditioning system is effectively reduced; on the other hand, the size of the outdoor units is effectively reduced, thus the conveying amount of the outdoor units is increased, and the conveying cost is reduced.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a multi-connected air conditioning system. Background technique [0002] The multi-connected air-conditioning system has a high energy efficiency ratio, and the cold (heat) is directly transported by the refrigerant, reducing heat exchange links, and is suitable for various load-changing places. [0003] For multi-connected air conditioning systems, in order to prevent the refrigerant from flashing before entering the evaporator, a subcooling device is usually added in the outdoor unit to increase the degree of subcooling, so that the refrigerant is in a supercooled state when it enters the throttle part of the indoor unit. [0004] In the vapor compression refrigeration system, affected by the temperature of the cooling medium, the condenser has a limited subcooling capacity for the refrigerant, and generally the subcooling degree is small. In order to increase the u...
