Abstract

The invention discloses a noise reduction control method for a VRV (Varied Refrigerant Volume) system. The VRV system comprises an outdoor unit and a plurality of indoor units, wherein every indoor unit comprises an indoor heat exchanger and an electric expansion valve. The noise reduction control method comprises the following steps of obtaining the condensate depression of the indoor units which are in stand by states; controlling the opening of the electric expansion valves which are corresponding to the indoor units which are in the stand by states according to the condensate depression of the indoor units which are in the stand by states to reduce the noise of the indoor units which are in the stand by states. The VRV system can reduce the noise of the standby indoor units and improves the user experience during heating. The invention also discloses a VRF system.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a noise reduction control method for a multi-connection system and a multi-connection system. Background technique [0002] When the multi-split air conditioner is running in the heating mode, the electronic expansion valves of some unopened indoor units generally keep a partial opening to prevent the accumulation of refrigerant and refrigerating oil in the heat exchanger of the unopened indoor units, but it also causes Refrigerant flows through the unopened indoor unit, which is usually accompanied by the sound of refrigerant flow. In severe cases, it will make a hissing sound and form a certain noise, which will cause trouble to users and affect the use of users. Contents of the invention [0003] The object of the present invention is to solve at least one of the above-mentioned technical drawbacks. [0004] Therefore, an object of the present invention is to provi...
