It is connected to drying shed；Extraneous fresh air is entered by the channel B of the heat exchanger in the lower layer air duct.
The beneficial effects of the present invention are, using above-mentioned technical proposal, differentiated processing is carried out to levels air, in conjunction with
Other technologies means can effectively improve dry materials quality and drying efficiency；It is supplied to the hot wind entirety wind-warm syndrome of drying shed equal
Even, the temperature difference in upper down space is no more than 5 DEG C；Drying shed temperature can control 55 DEG C or less operations, precisely heat pump Energy Efficiency Ratio
Highest running section；Heat pump " frosting " phenomenon can be avoided to occur simultaneously.
In order to realize the high-effect integrated of major-minor evaporator, fresh air chamber, condenser, hydrofuge channel etc., effectively carry
High thermal efficiency.Preferably, which includes rectangular housing, and rectangular housing side is return side, and the lower return air is arranged in return side
Mouthful, the sides adjacent device condenser of return side, lower rectangular housing inner cavity between return air inlet and condenser is the lower layer air duct；
The upper layer air duct is set to the top in the lower layer air duct；
The opposite side device main evaporator of return side, the rectangular housing inner cavity between main evaporator and lower layer air duct are fresh air
Chamber, the connection of fresh air chamber are extraneous；
The A channel import of the heat exchanger leads to upper layer air duct and constitutes the moisture exhausting port, and the outlet pair of A channel is steamed
Device air inlet is sent out, secondary evaporator air outlet leads to fresh air chamber；Fresh air chamber is led in channel B import, and lower layer's wind is led in the outlet of channel B
Road.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
