As the further improvement of technique scheme, this has the air channel at least one fillet and turns round between its inlet and the outlet, make that air-flow enters into inside the air channel from cross flow fan output after, the outlet in the air channel can form and be the advection that blows straight up.
As the further improvement of technique scheme, said shell integral body is rectangular shape.
As the further improvement of technique scheme, the width of said cuboid is the thickness of shell, and said thickness is less than 150mm.
The invention has the beneficial effects as follows: the present invention adopts cross flow fan as blowing device, because the blower fan volume has dwindled with respect to the traditional centrifugal blower fan greatly, so the integral thickness of shell can be done very thinly, and then has dwindled the volume of fan coil complete machine; Simultaneously, cross flow fan can be exported air-flow stably, and noise is low, has improved the comfort level of people when using fan coil.
In addition; The present invention has designed the structure of air channel and heat exchanger especially; The advection of from the air channel, seeing off is the heat exchanger coils face through being obliquely installed to greatest extent, thereby obtains maximum rate of heat exchange, simultaneously; The heat exchanger that tilts has been saved more space, has guaranteed that shell can do thinner lighter small-sizedly.
Thin thickness of the present invention save to be installed and to be taken up room, and the unit noise is low, and comfort is high, is the fan coil of a comfortable, durable, fashion.
