As shown in figure 5, ventilation equipment further include the second hole 33 and the 4th on the basis of above-mentioned embodiment illustrated in fig. 4
Valve 74.Region of second hole 33 between heat exchanger 60 and air processor 34 and with the bottom plate of hollow structure 11
Inside connection, the 4th valve 74 is covered on the second hole 33.The setting of second hole hole 33 and the 4th valve 74 is used for root
The opening and closing of interior circulatory function are realized according to demand.
In natural climate season in transition, when outdoor temperature is more comfortable than indoor temperature, the first valve 71 is
Opening state, the second valve 72 are in off state, and third valve 73 is in an open state, and the 4th valve 74 is in off state, and first
Blower 91 and the second blower 92 are operating status；So indoor at this time uncomfortable foul atmosphere will be in the work of the first blower 91
It is sucked under from return air inlet 41 and enters return air chamber 42, successively entered by third valve 73 and third hole 43 hollow
In the interlayer of bottom plate 11, air draft chamber 52 is entered using the first hole 53, outdoor is finally expelled to by the first blower 91.So
It can be found that indoor uncomfortable foul atmosphere has bypassed heat exchanger 60, the air of indoor and outdoor does not carry out energy exchange；Together
When room outside air sucked under the action of the second blower 92 from air inlet 21 and enter air-inlet cavity 22, successively by air
Manage device 24, heat exchanger 60 and air processor 34, interior be finally sent by the second blower 92, the advantage that be room
The wind of outer comfort temperature directly introduces interior, realizes the function of bypass (bypass).
It is indoor if the recovery efficiency of heat exchanger 60 is not sufficiently high in extremely cold seasonal climate
Temperature and humidity can be not suitable for the needs of human body, and the first valve 71 is in off state at this time, and the second valve 72 is in off state, third valve
Door 73 is in an open state, and the 4th valve 74 is in an open state, and the first blower 91 stops, and the second blower 92 is operating status；So
Indoor air will suck from return air inlet 41 and enter return air chamber 42 at this time, successively pass through third valve 73 and third hole
43 enter in the interlayer of hollow bottom plate 11, enter wind pushing cavity 32 using the second hole 33 and the 4th valve 74, pass through
The processing of air processor 34, is finally sent into interior by the second blower 92；So it can be found that air-flow at this time is interior circulation shape
State, it is therefore prevented that the loss of indoor temperature and humidity, while indoor air can be made to be purified again.
In season in energy regenerating in need, the first valve 71 is in an open state at this time, and the second valve 72 is to open
State, third valve 73 are in off state, and the 4th valve 74 is in off state, and the first blower 91 and the second blower 92 are operation shape
State；After so indoor air and outdoor air will be by 60 positive energy exchanges of heat exchanger at this time, foul atmosphere is expelled to
It is outdoor that outdoor fresh air is sent into interior simultaneously.
In another embodiment, bottom plate is that the ventilation equipment of hollow structure can also be as shown in Figure 6, comprising: the second hole 33, the
Three holes 43 and the 4th valve 74.Second hole 33 is located at air processor 34 and heat exchanger 60 in 32 region of wind pushing cavity
Between bottom plate 11 on, and be connected to inside bottom plate 11.
Third hole 43 is located on the bottom plate 11 between the return air inlet 41 and heat exchanger 60 in 42 region of return air chamber, and with
The inside of bottom plate 11 is connected to.
When the first valve 71 is closed, the 4th valve 74 is opened, and the first blower 91 is halted state, and the second blower 92 is operation
When state；The room air entered from return air inlet 41 passes sequentially through third hole 43 and enters inside hollow bottom plate 11, then passes through
It crosses the second hole 33 and the 4th valve 74 enters wind pushing cavity 32, and after the processing of air processor 34, in the second blower 92
Under the action of entered the room by air outlet 31, realize in circulatory function.
