AI Technical Summary

Technical Problem

Existing heat exchangers cannot maintain high efficiency under different loads simultaneously, resulting in poor air conditioning efficiency at low and high loads.

Method used

Design a variable flow heat exchanger that, by adjusting the on or off state of the valve assembly under different loads, allows the heat exchange branches to form different numbers of flow paths to meet different load requirements.

Benefits of technology

This enables the heat exchanger to maintain efficient operation under both high and low loads, thereby improving the overall performance of the air conditioner.

Abstract

This application relates to the field of air conditioning equipment technology and discloses a variable flow heat exchanger, including a first manifold and a second manifold, a first heat exchange branch, a second heat exchange branch, and a third heat exchange branch. The first, third, and fifth heat exchange connection ends constitute a first main connection end, and the second, fourth, and sixth heat exchange connection ends constitute a second main connection end. The first main connection end is provided with a first valve body assembly, and the second main connection end is provided with a second valve body assembly, allowing the first and second valve body assemblies to be open or closed. When the air conditioner operates at a first load, the number of refrigerant flow paths formed by the three heat exchange branches is n1; when the air conditioner operates at a second load, the number of refrigerant flow paths formed by the three heat exchange branches is n2. The first load is greater than the second load, and n1 is greater than n2. This application also discloses an air conditioner.
