Abstract

The invention discloses an air conditioner and a control method, and belongs to the technical field of air conditioners. The air conditioner comprises a controller, a temperature sensor, an electric control component and a capacity-variable compressor assembly, wherein the electric control component is arranged on an outdoor unit of the air conditioner. The capacity-variable compressor assembly comprises a capacity-variable compressor. The air conditioner further comprises a heat-dissipating pipe set, wherein the heat-dissipating pipe set is connected to a refrigerant circulation pipeline and used for conducting heat dissipation on the electric control component. The controller is used for acquiring the outdoor environment temperature, controlling the capacity-variable compressor to work in a double-cylinder mode and controlling the flow of the refrigerant flowing through the heat-dissipating pipe set to be increased when the value of the outdoor environment temperature is greater than or equal to the preset temperature threshold. According to the air conditioner, the capacity-variable compressor and the heat-dissipating pipe set which is used for conducting heat dissipation on the electric control component are adopted, the operation modes of the capacity-variable compressor are switched according to the outdoor temperature conditions, the heat dissipation pipe set is controlled to conduct heat dissipation on the electric control component so as to enable the refrigerant outputted by the compressor to meet the requirements for indoor heat exchange and heat dissipation of the electric control component, and therefore the overall operation energy efficiency of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method. Background technique [0002] Conventional air conditioners mostly use mechanical compressors to increase the temperature and pressure of the refrigerant, such as piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. According to the number of compression cylinders inside the compressor, It can be divided into single-cylinder compressors, double-cylinder compressors and multi-cylinder compressors. Among them, for double-cylinder and multi-cylinder compressors with not less than one cylinder, the compression process is based on the connection between multiple cylinders. In order, the refrigerant is compressed in multiple stages in sequence. When the air conditioner is in normal operation, the compressor can only increase the temperature and pressure of the refrigerant according to a fixed single ...
