Introduce the operation principle of the cold and hot exchange ventilation fan of the present embodiment below in detail.
After user opens the power supply of cold and hot exchange ventilation fan, the alternating current of external power supply is converted to direct current by the direct-current switch power supply transformer 35 on direct-current switch power supply plate 33, and supply is to DC frequency-changing fan 42, and DC frequency-changing fan 42 is started working.Ventilation fan is when dispatching from the factory, certain control program has been write in its wireless module control panel 32, wireless module control panel 32 is according to the control program of its inside, the exhaust event controlling the air inlet and scheduled time length that ventilation fan realizes scheduled time length by outdoor section 20, indoor section 30 and wall inside portion 40 hockets, this scheduled time length sets in a control program, such as, in the present embodiment, scheduled time length is 70 seconds, namely, after ventilation fan carries out air inlet action in 70 seconds, switch to and carry out 70 seconds exhaust event.When air-flow passes through the elementary filter screen 22 of outdoor section 20, carried out first time filtration, purification, the impurity that in elimination air-flow, particle is larger by elementary filter screen 22; When air-flow arrives secondary filter screen 45 after DC frequency-changing fan 42, air-flow is purified further by secondary filter screen 45, thus realizes the double purified effect of environmental protection.When thermal current is through cool-heat-exchanger 43, cool-heat-exchanger 43 absorbs the heat in thermal current, and is stored by heat, when cold airflow is through cool-heat-exchanger 43, cool-heat-exchanger 43 is by the thermal release of storage and be delivered in cold airflow, realizes the exchange heat of hot and cold air, environmental protection and energy saving.
Remote control panel 10 is provided with multiple function button, as common air-conditioning, switch switch can be provided with, the adjusting key regulating ventilation fan state can also be set.The air inlet of ventilation fan or exhaust condition can be set as automatic transmission, air inlet in 70 seconds as mentioned above and exhaust in 70 seconds hocket, also user's free adjustment shelves can be set as, user can regulate the state of ventilation fan by the adjustment button on remote controller 10, such as, when regulating, wireless module control panel 32 and the remote controller 10 of indoor section 30 send signal simultaneously, and two signals utilize coding rule mutually to mate and realize just can controlling after pairing completes to use.
Visible, the utility model can pass through a ventilation fan, make the air-flow of indoor and outdoor alternately through outdoor section, indoor section and wall inside portion to realize the cold and hot exchange of air-flow and alternately exhaust or air inlet, the air of indoor and outdoor is made to realize continual alternate cycles, make the maintenance balance of indoor energy and air pressure, not only having achieved Intelligent cold-hot exchanges but also energy-conserving and environment-protective.
These are only a kind of mode of operation of the cold and hot exchange ventilation fan that the utility model relates to, certainly, also has other mode of operation, such as, wherein in a kind of mode of operation, plural cold and hot exchange ventilation fan forms cold and hot exchange ventilation fan group, one of them cold and hot exchange ventilation fan is main frame, at least one cold and hot exchange ventilation fan is in addition subsidiary engine, and main frame is used for independent air inlet or is vented separately, and the signal that subsidiary engine is used for sending according to main frame makes the exhaust contrary with main frame or intake operation.Such as, when main frame works with air-suction state, the signal that subsidiary engine can send according to the wireless module control panel of main frame, does the operation be vented, and to realize continual exhaust and air inlet, ensures heat and the air pressure balance of indoor and outdoor, energy-conserving and environment-protective.It is pointed out that the selection setting of main and auxiliaries can be realized by the control program of the wireless module control panel of ventilation fan, and wireless module control panel is also for setting the state of main frame, such as air inlet or exhaust.The selection of main and auxiliaries and the setting of Host Status can set when ventilation fan dispatches from the factory, and also can be set by remote controller by user.
Under the second mode of operation of the cold and hot exchange ventilation fan that the utility model relates to, the air-flow of indoor and outdoor can be made equally alternately through outdoor section, indoor section and wall inside portion to realize the cold and hot exchange of air-flow and alternately exhaust or air inlet by cold and hot exchange ventilation fan group, the air of indoor and outdoor is made to realize continual alternate cycles, make the maintenance balance of indoor energy and air pressure, not only having achieved Intelligent cold-hot exchanges but also energy-conserving and environment-protective.
In addition, no matter which kind of mode of operation cold and hot exchange ventilation fan is in, DC frequency-changing fan and cool-heat-exchanger are all arranged in the connection outdoor section of wall inside portion and the outer tube of indoor section, the space in body of wall can be made full use of, reduce the number of components of indoor section and outdoor section, thus reduce the taking up room at indoor and outdoors of whole cold and hot exchange ventilation fan.
It will be understood by those skilled in the art that; these are only the embodiment of the utility model optimum; can be improved according to the above description or be converted, do not made the improvement made under the prerequisite of creative work and conversion and all should belong to the protection domain of the utility model claims.
