AI Technical Summary

Technical Problem

When the indoor temperature is close to the set temperature, the existing air conditioners frequently stop at the temperature, resulting in large temperature fluctuations, high noise and affecting the service life of the compressor, reducing the reliability and user experience of the air conditioner.

Method used

An air conditioner is designed, including an indoor heat exchanger and a bypass heat exchanger. The flow path control device makes both work at the same time or only the indoor heat exchanger work, adjust the refrigerant flow rate, and avoid the phenomenon of temperature shutdown.

Benefits of technology

It effectively avoids frequent start and stop of the compressor, reduces noise, extends the compressor service life, improves the reliability and user experience of the air conditioner, and reduces indoor temperature fluctuations.

Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioner and a control method thereof. The air conditioner comprises an indoor heat exchanger, a flow path control device and a bypass heat exchanger located outdoors, and the indoor heat exchanger and the bypass heat exchanger are both used for refrigerating or heating. The flow path control device is configured to enable the indoor heat exchanger and the bypass heat exchanger to operate at the same time or only enable the indoor heat exchanger to operate. The purpose that the air conditioner does not stop when reaching the temperature can be achieved, frequent starting and stopping of the compressor are avoided, the problem of loud noise caused by discontinuity of sound emitted by the air conditioner is avoided, the service life of the compressor is prolonged, the reliability and safety of the air conditioner are improved, indoor environment temperature fluctuation is reduced, and the indoor environment temperature fluctuation is reduced. The sudden change of the indoor environment temperature is avoided, and the user experience is improved.
