Problems solved by technology

Air-injection enthalpy-enhancing compressors generally use a single rotor. When the compressor is running, the rotor is stressed in one direction, resulting in large vibration and noise.
Moreover, due to the limitation of noise, the maximum operating frequency of the compressor should not be too high, which undoubtedly limits the output capacity of the compressor, resulting in that the cooling and heating speed of the air conditioner is still not fast enough, and the effect is not good enough.
However, for ordinary air conditioners using dual-rotor air-jet enthalpy-increasing compressors, the compressor consumes more electric energy. Air conditioner energy efficiency ratio

Abstract

The invention discloses an air conditioner and a control method thereof. The air conditioner comprises a variable capacitance enthalpy increasing compressor device, an acquisition module, a temperature detector and a controller. The work modes of the variable capacitance enthalpy increasing compressor device include an ordinary compression mode, a single-cylinder enhanced vapor injection mode and a double-cylinder enhanced vapor injection mode. The acquisition module is used for acquiring the running mode of the air conditioner. The temperature detector is used for detecting the indoor environment temperature. The controller is connected with the variable capacitance enthalpy increasing compressor device, the acquisition module and the temperature detector. The controller controls the work modes of the variable capacitance enthalpy increasing compressor device according to the running mode of the air conditioner and the indoor environment temperature. According to the air conditioner in the embodiment, the refrigerating or heating speed can be increased, the refrigerating or heating effect can be improved, the running noise can be lowered, and meanwhile the energy efficiency ratio can be increased when the load is low.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for quality of life are also getting higher and higher. Among them, the popularity of air conditioners is an important part of improving the comfort of life. [0003] At present, in the related art, the cooling or heating effect of the air conditioner is improved by using an air injection enthalpy increasing compressor. The air-injection enthalpy-increasing compressor generally adopts a single rotor, and the rotor is under unidirectional force during operation of the compressor, resulting in relatively large vibration and noise. Moreover, due to the limitation of noise, the maximum operating frequency of the compressor should not be too high, which undoubtedly limits the output capacity of the compressor, resulting in t...
