Mixed flow air conditioner

Abstract

The invention relates to a mixed flow air conditioner. The mixed flow air conditioner comprises a shell body provided with an air inlet and an air outlet, a draught fan arranged in the shell body, a heat exchange device, a straight-through path, a first heat exchange air channel and a second heat exchange air channel. The straight-through path is configured into an upstream for communicating the heat exchange device and a downstream of the heat exchange device, so as to allow air at the upstream of the heat exchange device to directly pass through the downstream of the heat exchange device through the straight-through path. The first heat exchange air channel is configured to allow part of air subjected to heat exchange of the heat exchange device to flow to the air outlet through the first heat exchange air channel, and the air is mixed with air from the straight-through path and then is blown to an environment space. The second heat exchange air channel is configured to allow part of the air subjected to the heat exchange of the heat exchange device to flow to the air outlet through the second heat exchange air channel and then the air is directly blown to the environment space. The opening degrees of air inlet ends of the straight-through path, the first heat exchange air channel and the second heat exchange air channel are adjustable, so that the quantity of the air flowing into the straight-through path, the first heat exchange air channel and the second heat exchange air channel can be adjusted according to actual requirements, and a ratio of the mixed air to the heat exchange air is adjusted.

Description

technical field [0001] The invention relates to household appliances, in particular to a mixed-flow air conditioner. Background technique [0002] The air duct structure of a common air conditioner in the existing market is generally composed of an air inlet, a centrifugal fan, an evaporator and an air outlet. Indoor air enters the interior of the air conditioner from the air inlet, and after being centrifugally accelerated by the centrifugal fan, the air passes through the evaporator for heat exchange, and the air after heat exchange is blown into the room through the air outlet. However, the temperature of the cool air blown out from the air outlet is too low and not soft enough, and it will cause discomfort to the user when blown on the body. [0003] In order to solve the above technical problems, a drainage air conditioner has appeared in the prior art, which introduces a little indoor air at the air outlet of the air conditioner, and mixes it with the cool air after h...

Problems solved by technology

However, the effect of this air-drawing air conditioner to relieve the overall temperature in the room is not obvious, and the cooling and / or heating speed is relatively slow

At the same time, this kind of drainage air conditioner also requires a comprehensive transformation of the air duct structure and air outlet of the air conditioner, resulting in an oversized air conditioner and high air conditioning costs
