The aperture of the air returning valve 3111.If indoor air quality is better, the aperture of the air inlet valve 3211 is smaller, the exhaust valve 3121
Aperture is smaller, the aperture of the mixer selector valve 3112 is bigger.At this point, first switching valve 331, the second switching valve 332 are turned off, it should
Heat recovery apparatus 33 works normally.
While it is working, the flow direction of wind is formed by 3：
Fresh air successively passes through the air inlet valve 3211, the filter 3212, the heat recovery apparatus 33, mixes air duct 323 and return air at this
Mixing is sent into air-line system by the air-treatment cylinder 324, the air funnel 325, the blow valve 3251.
Indoor exhaust wind is successively passed through air returning valve 3111, the exhaust tube 312, the return air cylinder 311, the heat recovery apparatus 33, is somebody's turn to do
Outdoor is discharged in exhaust valve 3121.
Indoor return air successively passes through the air returning valve 3111, the exhaust tube 312, the return air cylinder 311, the mixed air duct 323, the sky
Gas disposal cylinder 324, the air funnel 325, the blow valve 3251 are sent into air-line system.
In the air-conditioner set 30 refrigeration, if outdoor air enthalpy is less than room air enthalpy, 10 basis of controller
The temperature difference of room air and outdoor air controls the aperture of the air inlet valve 3211, the exhaust valve 3121, the air returning valve 3111.
Aperture state is design maximum opening state at this time for the air inlet valve 3211 and exhaust valve 3121.When outside air temperature is less than interior
When air themperature, the temperature difference of outdoor air and outdoor air is bigger, then the aperture of air inlet valve 3211 is smaller, the exhaust valve
3121 aperture is smaller, the aperture of the mixer selector valve 3112 is bigger.At this point, first switching valve 331, the second switching valve 332 are opened
It opens, which does not work.
In the air-conditioner set 30 heating, result which detect according to indoor air quality detection device 23 with
It is required that controlling the aperture of the air inlet valve 3211, the exhaust valve 3121, the air returning valve 3111.Indoor air quality is poorer, then should be into
3211 aperture of air-valve is bigger, and 3121 aperture of exhaust valve is bigger, 3111 aperture of air returning valve is smaller.Conversely, air quality is better,
Then 3211 aperture of air inlet valve is smaller, and 3121 aperture of exhaust valve is smaller, 3111 aperture of air returning valve is bigger.At this point, this first
Switching valve 331, the second switching valve 332 are turned off, which works normally.
