Condenser flow path structure, condenser flow path control method and air conditioner

Abstract

The invention discloses a condenser flow path structure, a condenser flow path control method and an air conditioner, and relates to the field of air conditioners. The condenser flow path structure comprises a first flow path, a second flow path and a four-way valve assembly a, the four-way valve assembly a comprises a first valve pipe, a second valve pipe, a third valve pipe and a fourth valve pipe, and the first valve pipe is in communication with the third valve pipe; a first control valve is arranged on the first valve pipe, the second valve pipe is in communication with the fourth valve pipe, and a second control valve is arranged on the fourth valve pipe; the first valve pipe is in communication with the fourth valve pipe through a first connecting pipe, a third control valve is arranged on the first connecting pipe, the first valve pipe and the second valve pipe communicate with the first flow path, and the third valve pipe and the fourth valve pipe communicate with the second flow path. The number of branches of an internal pipeline of a condenser and flow of each branch are controlled through a control valve, so that the temperature value of each branch is balanced, and the heat exchange performance is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a condenser flow path structure, a control method and an air conditioner. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . [0003] For air conditioner condensers, the flow state of the refrigerant is an important factor affecting the performance of the heat exchanger. Uneven flow distribution can easily lead to a significant decrease in the total heat transfer of the heat exchanger. At the same time, in the heating mode, due to the decrease of the external ambient temperature, the pressure drop increases when the refrigeran...

Uneven flow distribution can easily lead to a significant decrease in the total heat transfer of the heat exchanger

At the same time, in the heating mode, due to the decrease of the external ambient temperature, the pressure drop increases when the refrigerant evaporates, and the improvement of heating performance is limited.
