Problems solved by technology

Ordinary inverter air conditioners mostly use single-stage compressors due to cost reasons. Due to the unidirectional force on the rotor, the vibration and noise are relatively large, and high-temperature refrigeration and low-temperature heating cannot meet the needs of special users; Under low frequency operation, the system stability is too poor

Abstract

The invention discloses an air conditioning system and a control method thereof. The air conditioning system comprises an enhanced vapor injection compressor, a reversing component, two heat exchangers, a flash evaporator and a control device. The enhanced vapor injection compressor comprises a shell, a first-stage compression component and a second-stage compression component. The shell is provided with an exhaust port, an air supply port and two air suction ports, the two air suction ports are connected with air suction passages of the first-stage compression component and the second-stage compression component respectively, and an exhaust passage of the first-stage compression component is connected with the air suction passage of the second-stage compression component. A fourth valve port is respectively connected with the two air suction ports through a three-way division valve. The control device is used for acquiring an operating frequency of the enhanced vapor injection compressor and controlling operating conditions of the three-way division valve according to the operating frequency of the enhanced vapor injection compressor to select an operating mode of the enhanced vapor injection compressor. The air conditioning system has the advantages that a dual-stage compression mode is adopted in medium and high frequencies to increase refrigeration and heating speeds; a single-stage compression mode is adopted in low frequency, and accordingly energy saving and comfort are realized.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-conditioning system and a control method for the air-conditioning system. Background technique [0002] With the improvement of living standards, people's requirements for household air conditioners are also getting higher and higher. For example, household air conditioners are required to not only provide strong cooling at high temperatures and strong heating at low temperatures, but also save energy and electricity. Ordinary inverter air conditioners mostly use single-stage compressors due to cost reasons. Due to the unidirectional force on the rotor, the vibration and noise are relatively large, and high-temperature refrigeration and low-temperature heating cannot meet the needs of special users; Under low-frequency operation, the system stability is too poor. Contents of the invention [0003] The present invention aims to solve at least one of the ...
