Problems solved by technology

Since the heat exchanger with refrigerant flow shares a fan system with the rest of the heat exchangers, part of the air volume of the fan system passes through the rest of the heat exchangers without refrigerant flow, which reduces the utilization of the heat exchange area
Moreover, the multiple heat exchangers of multi-refrigeration system air conditioners also have the problem of uneven outlet temperature, so there is a need for improvement

Abstract

The invention discloses a heat exchanger and a multi-refrigeration system air-conditioning unit. The heat exchanger according to the embodiment of the invention includes a first header, a second header, a third header, a fourth header, heat exchange tubes and fins, the heat exchange tubes include first heat exchange tubes and second heat exchange tubes, the first heat exchange tubes and the second heat exchange tubes are arranged alternately along the length direction of the header, the first heat exchange tubes The tube and / or the second heat exchange tube has a bent section and includes a first section, a middle section and a second section, the heat exchanger includes a first part, a middle part and a second part, and the middle part of the heat exchanger Including the middle section and the fins, the first part of the heat exchanger includes the first section, and the airflow flowing through the heat exchanger passes through the middle part of the heat exchanger and the heat exchanger successively. the first part of the heat exchanger, or successively pass through the first part of the heat exchanger and the middle part of the heat exchanger. The heat exchanger of the invention improves the utilization rate of the heat exchange area.

Description

technical field [0001] The invention relates to the technical field of heat exchange, and more specifically, to a heat exchanger and a multi-refrigeration system air-conditioning unit with the heat exchanger. Background technique [0002] Multiple refrigeration system air conditioners use multiple separate refrigerant circuits. In order to adapt to multi-refrigeration system air conditioners, the heat exchanger in the refrigerant circuit is a multi-system heat exchanger. [0003] In the related art, multiple refrigeration system air conditioners use multiple independent refrigerant circuits, and multiple heat exchangers in the multiple refrigerant circuits usually share one fan system and one ventilation surface. [0004] During partial load operation, refrigerant flows in the heat exchangers of a part of the refrigerant circuit in the multi-refrigeration system air conditioner, and no refrigerant flows in the rest of the heat exchangers. Since the heat exchanger with refr...
