Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.To those skilled in the art, it can understand that above-mentioned term exists as the case may be
Concrete meaning in the present invention.
As shown in Figure 1, fresh air conditioner system of the invention mainly includes fresh air pipeline 1, heating device 2 and air conditioner indoor unit
3.Wherein, outdoor is led in 1 one end of fresh air pipeline, and the other end leads to interior, specifically leads to the inside of air conditioner indoor unit 3.Heating
Device 2 is arranged in fresh air pipeline 1, for heating the air for flowing through fresh air pipeline 1.
Although not showing that in figure, fresh air conditioner system of the invention further includes blower, blower and 1 phase of fresh air pipeline
Connection, for outdoor air to be introduced into fresh air pipeline 1.Preferably, blower is arranged in fresh air pipeline 1 close to air conditioner indoor unit
3 one end.Alternatively, those skilled in the art can also root under the premise of outdoor air can be introduced into fresh air pipeline 1
According to needs, blower is arranged in any position of fresh air pipeline 1, such as the air inlet of fresh air pipeline 1 is set.
With continued reference to Fig. 1, there is evaporator 4, fan 5 and carbon dioxide sensor 6 in air conditioner indoor unit 3.Wherein, dioxy
Change the concentration that carbon sensor 6 is used to detect indoor Carbon Dioxide in Air.Although not showed that in figure, air conditioner indoor unit 3
On be provided with for detect it is indoor whether there is people existing for personnel to feel detection module, the people feels detection module and is preferably infrared inspection
Survey sensor.It should be noted that it is attached it is shown in fig. 1 be only air conditioning system part-structure related to the present invention, due to
Air conditioning system is system well-known to those skilled in the art, so no longer say to structure unrelated to the invention herein
It is bright.
With continued reference to Fig. 1, fresh air pipeline 1 includes main line 11 and bye-pass 12, and the both ends of main line 11 respectively lead to room
Outer and indoor, the both ends of bye-pass 12 are connected to main line 11 respectively, and heating device 2 is arranged in bye-pass 12.In order to improve
Heating efficiency, heating device 2 of the invention are preferably electric heater unit.Electric heater unit leaks electricity in order to prevent, the electric heating
Device is preferably the heating wire for being enclosed with insulating layer.
With continued reference to Fig. 1, air conditioning system of the invention further includes the control valve 7 being arranged on main line 11, control
Main line 11 is in parallel with bye-pass 12 when valve 7 is opened, and outdoor air can enter main line 11 and bye-pass 12 simultaneously, control
Main line 11 is connected with bye-pass 12 when valve 7 is closed, and outdoor air is all had to across bye-pass 12.
Further, although not showing that in figure, air conditioning system of the invention further includes controller, is arranged in room
The second temperature sensor of outer the first temperature sensor and setting indoors, the controller and heating device 2, the wind
Machine, control valve 7, first temperature sensor and the second temperature sensor are respectively connected with.
When air conditioning system of the invention executes inletting fresh air program in winter:
Controller starts turning the blower, and outdoor fresh air is introduced interior by fresh air pipeline 1.At the same time,
Before or after, controller first passes through the first temperature sensor and obtains outdoor environment temperature T0, passes through second temperature sensor
Indoor environment temperature T1 is obtained, value of delta T=T1-T0 between the two is then calculated.Subsequent controller by δ T with prestore the
One threshold value is compared.When δ T is lower than the first threshold, it is electric that controller will not be such that heating device 2 obtains, and makes at control valve 7
In open state, it is just able to enter interior so that fresh air can be not passed through bye-pass 12, is avoided in bye-pass 12 due to heating
The presence of device 2 and hinder fresh air, generate wind pressure, waste of energy；When δ T is higher than the first threshold, controller fills heating
Setting 2 must be electric, and control valve 7 is made to be switched to closed state, is added with guaranteeing that fresh air all has to pass through bye-pass 12 by heating device 2
Heat.Preferably, the heating power of heating device 2 and δ T be higher than the first threshold number it is related, specifically, δ T is than described the
As soon as threshold value is bigger, the heating power of heating device 2 is bigger, on the contrary then smaller.To guarantee the fresh air entered the room and interior
Environment temperature it is close, prevent room temperature from declining the too fast comfort level for influencing user.
It should be noted that the first threshold can be any feasible numerical value, such as 1 DEG C, 3 DEG C, 5 DEG C etc..
Alternatively, those skilled in the art can also be as needed, by adjusting the revolving speed of blower, entered the room newly to change
The rate of wind is sufficiently heated the fresh air in fresh air pipeline 1.
In addition, those skilled in the art also can according to need, the outdoor ring only detected by the first temperature sensor
Border temperature T0 is to determine whether open heating device 2.Specifically, when second threshold of the T0 lower than setting, heating can be opened
Device 2.What the second threshold indicated is human body sensory to cold environment temperature, such as 18 DEG C, 20 DEG C, 12 DEG C etc..
Certainly, those skilled in the art also can according to need, and set one for fresh air pipeline 1, and selectively will
The outside or inside of a fresh air pipeline 1 is arranged in heating device 2.
Based on description above, it will be appreciated to those of skill in the art that by setting heating device 2 to fresh air pipeline
Air in 1 is heated, and when so that air conditioning system of the invention executing inletting fresh air operation in winter, can pass through heating
Device 2 heats fresh air, improves the temperature of fresh air, so as to make fresh air enter after interior with indoor environment temperature phase
It is close, it ensure that the comfort of user.
In addition, in another feasible embodiment of the invention, unlike above-mentioned preferred embodiment, heating dress
It is multiple for setting 2.The power of multiple heating device 2 can be identical, so that multiple heating device 2 can be applied in combination, thus
Generate different heating powers；The power of multiple heating device 2 can also be different, so that multiple heating device 2 individually makes
Used time also can produce different heating powers.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
