Switching device used for multi-split air conditioner and multi-split air conditioner with switching device

Abstract

The invention discloses a switching device used for a multi-split air conditioner and the multi-split air conditioner with the switching device. The switching device used for the multi-split air conditioner comprises a base, a water receiving disc, a plurality of vibration reduction pads and a plurality of fixing parts; the base comprises a bottom wall and side walls, the side walls surround the bottom wall and extend from the edge of the bottom wall upwards, the water receiving disc is arranged in the base, and the bottom face of the water receiving disc and the bottom wall of the base are vertically spaced, and the vibration reduction pads are arranged on the water receiving disc and arranged in the circumferential direction of the water receiving discs at intervals; the fixing parts are arranged on the vibration reduction pads and are connected with the side walls of the base, and the fixing parts are spaced from the water receiving disc. According to the switching device used for the multi-split air conditioner, the phenomenon that noise generated by flowing of refrigerants over a heat exchange system is spread to the base through the water receiving disc is effectively avoided, and therefore the noise of the air conditioner with the switching device is greatly reduced; the use occasion and the mounting position of the air conditioner are expanded, and the comfort of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a switching device for a multi-connected air conditioner and a multi-connected air conditioner having the same. Background technique [0002] In the related art, in the switching device of the air conditioner, the water receiving tray is usually arranged inside the base, and the heat exchange components are installed above the water receiving tray, so that the water receiving tray collects the condensed water generated by the heat exchange components. However, the noise generated when the refrigerant flows through the heat exchange system will be transmitted to the base through the water receiving tray, making the air conditioner noisy, thereby greatly limiting the use occasions and installation locations of the air conditioner. [0003] In addition, the air conditioner switching device can realize separate cooling and heating of different indoor units through the valve ...

AI Technical Summary

Problems solved by technology

However, the noise generated when the refrigerant flows through the heat exchange system will be transmitted to the base through the water tray, making the air conditioner noisy, which greatly limits the use and installation location of the air conditioner

[0003] In addition, the air conditioner switching device can realize separate cooling and heating of different indoor units through the valve body and related controls. However, due to the limitation of system settings and structural space, the number of connected indoor units is relatively limited, generally less than six interfaces. That is, the capacity is not large enough, and if the box size of the switching device is increased proportionally on the existing basis, the entire device will be too large, affecting the use occasion and installation location

In addition, many of the existing small switching devices are foamed inside the box, making the entire refrigeration component unable to be repaired
