Abstract

The invention discloses a heat exchanger assembly, a design method thereof and an air conditioner. The heat exchanger assembly comprises a first heat exchanger (1) and a second heat exchanger (2) which are connected in series through a cold carrying medium pipe (3); the first heat exchanger (1) is arranged on the leeward side of the second heat exchanger (2); and cold carrying media sequentially flow through the first heat exchanger (1) and the second heat exchanger (2), and return air sequentially flows through the second heat exchanger (2) and the first heat exchanger (1) so that the cold carrying media can perform cooling layer by layer along the first heat exchanger (1) and the second heat exchanger (2), and the and return air can perform cooling layer by layer along the second heat exchanger (2) and the first heat exchanger (1). According to the heat exchanger assembly, the sensible heat factor is increased while sufficient cold amount is guaranteed, and the dehumidifying amount is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger assembly, a design method thereof, and an air conditioner. Background technique [0002] In the chilled water machine room air conditioner, the sensible heat ratio of the air conditioner is very high, and the area of ​​the heat exchanger is relatively large. The air conditioner with a lower sensible heat ratio has a large dehumidification capacity and high energy consumption, which is a great challenge for energy saving. At present, most users use to reduce dehumidification and increase the sensible heat ratio by increasing the inlet water temperature, but this method will affect the cooling speed and reduce the heat exchange. Contents of the invention [0003] Embodiments of the present invention provide a heat exchanger assembly and its design method, and an air conditioner, which can increase sensible heat ratio and reduce dehumidification while ens...
