For solving the problems of the technologies described above, realize inventive problem, the technical solution used in the present invention is as follows:
The invention discloses a kind of pair of air port cabinet type air conditioner indoor set, indoor set partly includes cabinet, air outlet, upper return air inlet, lower return air inlet, blower fan, cross valve, single-chip microcomputer, reversal valve or motor-driven valve, blower fan includes motor, fan blade and air channel, and described fan blade is centrifugation blade.Blower fan is containing air inlet and two air ports of air outlet.Described blower fan is positioned at the middle and lower part of cabinet, and air inlet is communicated with upper return air inlet and the lower return air inlet of air-conditioner simultaneously, and the air outlet of blower fan is communicated with the air outlet of air-conditioner.Described connection is all communicated with air channel.On air inlet and air-conditioner return air inlet be connected to upper air duct, under air inlet and air-conditioner, return air inlet is lower air duct.The air outlet of described blower fan is provided with reversal valve to the place, public air channel of upper lower air duct, for winter summer condition, switches, and switches return air inlet and increases disturbance to reach the uniform object of indoor temperature.Or on upper and lower air channel, motor-driven valve is installed respectively, by switch valve or the aperture that changes valve, is achieved the goal.In order to realize intelligent control, the cross valve of reversal valve and cabinet air conditioner can be interlocked, or the motor-driven valve on upper and lower air channel is connected with single-chip microcomputer respectively.
The present invention is by arranging upper and lower two return air inlets, its obvious effect: the one, and indoor temperature field trend is even, optimization airflow tissue.The 2nd, improved the result of use of air-conditioning, have more energy-saving effect.During cooling condition, air outlet is sent cold wind, and cold wind sinks naturally, and the top of air outlet does not just reach the effect of refrigeration.Now open top return air inlet, extract the hot blast on top out, the thin bottom cold wind that will make of upper air, very naturally to top diffusion, has increased the disturbance between air like this, can make whole room reach faster design temperature.Whole room temperature is consistent, and the people that will solve near cabinet air-conditioner feels colder, away from the people of air-conditioning, feels hotter problem.Indoor air temperature in air conditioned building is consistent, the consistent expression here be that in sustained height direction, temperature is basic identical, on vertical direction, still have the temperature difference but be more or less the same, but still can substantially meet the requirement of human body comfort.Under heating condition, open lower return air inlet, principle and summer are basic identical.For the result of use that improves air-conditioning, now only take winter as example: during conventional cabinet air-conditioner air-supply, forms the separate layer that above air outlet is boundary, the above region of separate layer upper cold and lower heat, separate layer is with lower area upper heat and lower cold, therefore, although the temperature in room is higher than ambient temperature, separate layer with the mean temperature of lower area than low many of the mean temperature in the above region of separate layer.For making the temperature of bottom, room reach design temperature, will continue heating, so just caused the waste of the energy.Winter condition in the present invention is opened lower return air inlet increase disturbance can make hot-air more than air port move down preferably, reaches and makes room temperature in the effect that does not continue to reach unanimity under the condition of heating, has improved the result of use of air-conditioning.
