The technical scheme of the utility model technology is achieved in that and a kind ofly can regulates with indoor and outdoor temperature the mixed ventilation device of air quantity, it is characterized in that: comprise solar energy heat absorbing box main body, blower fan and exhaust duct, the outlet on described solar energy heat absorbing box main body top is directly communicated with outside atmosphere, the import of described solar energy heat absorbing box main body bottom is communicated with exhaust duct one end, the described exhaust duct other end is communicated with the air outlet of blower fan, described blower fan air inlet by valvular pipeline is set, be communicated with room internal upper part.
Described in the utility modelly can with indoor and outdoor temperature, regulate the mixed ventilation device of air quantity, it is respectively arranged with temperature sensor inside and outside described room, and described temperature sensor is connected with controller, and described controller is connected with the switch of controlling blower fan start and stop.
Described in the utility modelly can regulate with indoor and outdoor temperature the mixed ventilation device of air quantity, described in it, the start and stop of blower fan are controlled by the temperature inside and outside room, when summer, when outdoor temperature is during lower than indoor temperature, fan operation, otherwise do not move, control the temperature of blower fan start and stop and utilize copper constantan resistance to measure.
Described in the utility modelly can with indoor and outdoor temperature, regulate the mixed ventilation device of air quantity, it is provided with solar energy heat collector on described solar energy heat absorbing box main body, and the stainless steel that described solar energy heat collector is painted black forms.
The utility model utilizes the difference of indoor and outdoor temperature, according to actual conditions, control the start and stop of blower fan, when outside air temperature is during lower than indoor air temperature, by blower fan, strengthen indoor ventilation amount, to indoor carry out aeration-cooling, when outside air temperature is during higher than indoor air temperature, close blower fan, only utilize hot pressing effect to guarantee the requirement of the basic resh air requirement of indoor occupant, and in the winter time time by valve by whole device shutdown, like this, by being used in conjunction with of gravity-flow ventilation and force ventilation, reaching and improve indoor air quality and energy-conservation object.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
Mark in figure: 1 is solar energy heat absorbing box main body, 2 is blower fan, and 3 is exhaust duct, and 4 is outlet, and 5 is import, and 6 is valve, and 7 is room, and 8 is solar energy heat collector.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model technology is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind ofly can regulate with indoor and outdoor temperature the mixed ventilation device of air quantity, comprise and be arranged on outdoor solar energy heat absorbing box main body 1, blower fan 2 and exhaust duct 3, described solar energy heat absorbing box main body is hollow translucent construction, the outlet 4 on described solar energy heat absorbing box main body 1 top is directly communicated with outside atmosphere, the import 5 of described solar energy heat absorbing box main body 1 bottom is communicated with exhaust duct 3 one end, described exhaust duct 3 other ends are communicated with the air outlet of blower fan 2, the air inlet of described blower fan 2 is communicated with room 7 internal upper parts by being provided with the pipeline of valve 6, on described solar energy heat absorbing box main body 1, be also provided with solar energy heat collector 8, the stainless steel that described solar energy heat collector 8 is painted black forms, the temperature that can raise fast in solar energy heat absorbing box main body.
Wherein, inside and outside described room 7, be respectively arranged with temperature sensor, described temperature sensor is connected with controller, and described controller is connected with the switch of controlling blower fan 2 start and stop, the start and stop of described blower fan 2 are controlled by the temperature inside and outside room, when summer, when outdoor temperature is during lower than indoor temperature, fan operation, by blower fan, strengthen indoor ventilation amount, to indoor, carry out aeration-coolingly, otherwise do not move, control the temperature of blower fan 2 start and stop and utilize copper constantan resistance to measure; In the time of in the winter time, thereby valve closing is by whole device shutdown.Wherein said controller is to adopt existing equipment, and it is only to adopt this existing equipment to realize signal to accept the control with blower fan start and stop, in this application for controller itself without any improvement.
Operation principle of the present utility model:
In transition season and the period that need to lower the temperature summer, when outside air temperature is during lower than indoor air temperature, fan starting, indoor hot-air is discharged into outside atmosphere by blower fan, exhaust duct, solar energy heat absorbing box main body successively from room, indoorly like this will form negative pressure, outdoor cold air enters indoor by door and window etc., play the effect of cooling.In the time of in the winter time, do not need to utilize outdoor air to lower the temperature to indoor, therefore utilize the whole equipment of valve closing.
When outside air temperature is during higher than indoor air temperature, blower fan cuts out, can not be room temperature lowering by outdoor temperature, need to reduce outdoor air toward indoor moveable (all windows, Men Junhui close) as far as possible, but must guarantee the requirement of the basic resh air requirement of indoor occupant.Now, the hot pressing forming in the solar energy heat absorbing box main body of hollow printing opacity meets the minimum rate of ventilation requirement of thermal comfort in can drive chamber.
To sum up, whether the utility model is considered transition season and can be used summer outdoor air to automatically switch in aeration-cooling situation to indoor carrying out.When outside air temperature is during lower than indoor air temperature, by blower fan, strengthen indoor ventilation amount, to indoor carry out aeration-cooling; When outside air temperature is during higher than indoor air temperature, close blower fan, only utilize hot pressing effect to guarantee the requirement of the basic resh air requirement of indoor occupant.This device has reached the efficient utilization to solar energy, and construction and operation maintenance are comparatively simple, convenient.
