Air inlet structure provided with double centrifugal fans and air conditioner comprising air inlet structure

Abstract

The invention provides an air inlet structure provided with double centrifugal fans and an air conditioner. The air inlet structure comprises a main air duct and the two centrifugal fans, wherein air outlets of air outlet channels of volutes of the two centrifugal fans communicate with an inlet end of the main air duct; the air outlet channels of the volutes of the two centrifugal fans gradually become parallel towards the direction of the air outlets and are in the parallel state at the air outlets; the air conditioner comprises a cabinet shell, a heat exchanger arranged in the cabinet shell and the air inlet structure, air flow in the main air duct of the air inlet structure is subjected to heat exchange by the heat exchanger and then is guided out through air outlet holes in the side wall of the cabinet wall. On the premise that the size of the air conditioner is reduced, the air conditioner has the advantages that the internal circulating air volume is increased, the heat exchange capacity is improved, and energy consumption and noise are reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air intake structure with double centrifugal fans and an air conditioner thereof. Background technique [0002] The traditional indoor air-conditioning cabinet includes a cabinet casing, an air inlet structure arranged in the cabinet casing, and a heat exchanger, wherein the air inlet structure is a centrifugal fan, and the centrifugal fan pumps the air outside the cabinet casing to the heat exchanger. At the heater, the heat is exchanged through the heat exchanger and discharged out of the cabinet shell to realize heat exchange. In order to increase the heat exchange rate of traditional indoor air-conditioning cabinets, it is often achieved by increasing the diameter of the blades of the fan and increasing the size of the heat exchanger, which easily leads to a larger shell size of the air-conditioning cabinet. However, in modern society, family residences, especially small-s...

Problems solved by technology

[0004] Therefore, the technical problem to be solved in the present invention is to overcome the fan in the air inlet structure of the air conditioner of the prior art is only a simple increase in number, so that the two streams coming out from the outlet passages of the two fans merge into a single airflow. There will be collision interference in the air duct, which will lead to a large loss of pressure head and low energy efficiency. It provides a dual-centrifugal fan with high energy efficiency.
