In the air-conditioning air return device in the prior art, return air uniformly returns to the front end of the condensing coil to cause overlarge air volume, and water drops on the condensing coil are brought into a pipeline again to enter a dust-free workshop to cause the humidity to exceed the standard; the air conditioner consumes too much energy because the heating system is completely started due to the excessive humidity of the workshop.
In the invention, especially in winter, part of the treated hot air in the workshop (dust-free room) returns to the front end of the centrifugal fan and directly returns to the workshop again without passing through the condensing coil, thereby reducing the running number of the heating pipes. The secondary return air can reduce the air volume of the main return air pipeline and prevent spray of the condensing coil from splashing, so that the secondary return air cannot be brought into a workshop through the air pipe again. After the secondary return air technology is improved, about 14 thousands of electricity charges are saved each month.
According to fig. 1, an air conditioner return air recycling device, including air conditioning system 4, main return air pipe 1, main return air pipe return air end 17 communicates with air conditioning system's condensing coil 6 front end, the air inlet end intercommunication dust free chamber of main return air pipe, the both ends of main return air pipe are main return air pipe return air end, main return air pipe air inlet end respectively, still include the secondary return air pipe 2 that branches from main return air pipe, secondary return air pipe 2 communicates with air conditioning system's fan front end (for example centrifugal fan 9 front end, also can be other fans). The return air of the secondary return air pipe does not pass through the condensing coil. That is, the return air end 18 of the secondary return air pipe is communicated with the front end of the fan, and the secondary return air enters the front end of the fan, flows through the fan, the air inlet pipe 13 and the like and then enters the dust-free room.
The core innovation point of the invention is that a secondary air return pipe is branched from a main air return pipe, so that secondary air return does not pass through a condensing coil, and the energy consumption is reduced. Other alternatives (e.g., different air conditioning system configurations and variations in relative positions of components) are within the scope of the invention, so long as the objectives of the invention are achieved.
In a preferred embodiment, the secondary air return pipe is provided with an adjusting valve 3 for adjusting the secondary air return amount, namely, the adjusting valve can adjust the air return amount of the secondary air return pipe, and the total air return amount = the secondary air return amount + the air return amount of the main air return pipe, so that the air amount of the main air return pipe can be reduced and the splash of the condensing coil pipe can not splash after the secondary air return pipe is arranged. Specifically, the secondary air return pipe is communicated with the front end of the centrifugal fan through a secondary air return end 18 of the secondary air return pipe.

Preferably, the front end of the fan refers to a position between the centrifugal fan and the electric humidifier.
The communication position of the secondary air return pipe and the main air return pipe is positioned at the non-end part of the main air return pipe.
In the preferred embodiment, the main return duct return air end is in communication with the primary-to-intermediate filter front end of the air conditioning system, in which case the main return duct return air end would still be understood to be in communication with the condenser coil front end. The primary and intermediate filters are available in the prior art, are formed by combining a primary filter and an intermediate filter, are commercially available, and refer to Chinese patent ZL201721465264.X, Chinese patent ZL201720674771.8 and the like.
