Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart of an implementation of a method for controlling a passive room ventilator according to an embodiment of the present invention, and for convenience of description, only parts related to the embodiment of the present invention are shown. The execution main body of the embodiment of the invention can be terminal equipment.
In the embodiment of the invention, the fresh air fan can comprise a heat exchange module, an air inlet channel and an air exhaust channel, and the heat exchange module is used for carrying out heat exchange on the air inlet channel and the air exhaust channel.
The air inlet channel is used for introducing fresh air from the outside to each room in the passive room, and the air outlet channel is used for exhausting foul air from each room in the passive room to the outside. When the air inlet channel is used for feeding fresh air and the air exhaust channel is used for exhausting turbid air, heat exchange can be carried out through the heat exchange module. When the temperature in the air exhaust channel is higher than that in the air inlet channel, the temperature of the air inlet channel can be increased through the heat exchange module; when the temperature in the exhaust channel is lower than the temperature in the air inlet channel, the temperature of the air inlet channel can be reduced through the heat exchange module.
As shown in fig. 1, the method for controlling a passive room ventilator may include the following steps:
s101: monitoring whether the carbon dioxide concentration of each room of the passive room is larger than a first preset carbon dioxide concentration threshold value.
In the embodiment of the invention, whether the carbon dioxide concentration of each room in the passive room is greater than a first preset carbon dioxide concentration threshold value is monitored in real time; and if not, continuously monitoring whether the carbon dioxide concentration of each room in the passive room is greater than a first preset carbon dioxide concentration threshold value.
The first preset carbon dioxide concentration threshold is the upper limit value of the carbon dioxide concentration, when the indoor carbon dioxide concentration is larger than the first preset carbon dioxide concentration threshold, a person is in an uncomfortable environment, and a fresh air fan needs to be started to reduce the indoor carbon dioxide concentration. The first preset carbon dioxide concentration threshold value can be set according to actual conditions.
S102: if the first target room with the carbon dioxide concentration larger than the first preset carbon dioxide concentration threshold exists, the new fan is controlled to be started, a ventilation opening of the first target room is controlled to be opened, and whether the current temperature of the first target room is within a preset temperature range or not is monitored.
The first target room is a room with the carbon dioxide concentration in the passive room being greater than a first preset carbon dioxide concentration threshold. The number of the first target rooms is not limited, and may be one or more.
The air vent of the first target room is an air port which is connected with an air inlet channel and an air exhaust channel of the fresh air machine and can be used for air inlet and air exhaust. The ventilation opening can be a wind opening, and can be used for wind inlet and wind exhaust; the ventilation opening can also be two air openings, wherein one air opening is connected with an air inlet channel of the fresh air machine and used for air inlet, and the other air opening is connected with an air exhaust channel of the fresh air machine and used for air exhaust.
If the passive room has the first target room, the new fan is controlled to be started, the ventilation opening of the first target room is controlled to be opened, meanwhile, whether the current temperature of the first target room is within a preset temperature range is monitored, and if the current temperature of the first target room is within the preset temperature range, whether the current temperature of the first target room is within the preset temperature range is continuously monitored.
Optionally, before controlling the fresh air machine to start, the method may further include:
detecting whether a new fan is started;
if the new fan is started, the step of controlling the start of the new fan is not required to be executed, and the step of controlling the opening of the ventilation opening of the first target room is continuously executed;
and if the new fan is not started, continuing executing the step of controlling the start of the new fan.
S103: and if the current temperature of the first target room is not within the preset temperature range, controlling the air conditioner of the first target room to be started, and adjusting the water temperature value of the air conditioner of the first target room according to the heat exchange efficiency of the heat exchange module, wherein the water temperature value is used for slowly adjusting the temperature of the first target room to be within the preset temperature range.
In the embodiment of the invention, if the current temperature of the first target room is not monitored to be within the preset temperature range, the air conditioner of the first target room is controlled to be started. The air conditioner adjusts the indoor temperature through the water temperature, and adjusts the water temperature to a higher temperature value when the temperature needs to be raised; when the temperature needs to be reduced, the water temperature is adjusted to a lower temperature value.
After the air conditioner is started, the water temperature value of the air conditioner in the first target room can be adjusted according to the heat exchange efficiency of the heat exchange module, so that the temperature of the first target room is slowly adjusted to a preset temperature range instead of being greatly adjusted in a short time, and the comfort can be improved.
As can be seen from the above description, the fresh air fan according to the embodiment of the present invention includes the heat exchange module, which can perform heat exchange between the air intake channel and the air exhaust channel, and determine whether to start the fresh air fan and whether to start the ventilation openings of the rooms by monitoring the concentration of carbon dioxide in the rooms; after the new fan is started and the ventilation opening of the first target room is opened, whether the temperature of the first target room is within a preset temperature range or not is monitored, if not, the air conditioner is started, the water temperature value of the air conditioner is adjusted according to the heat exchange efficiency of the heat exchange module, so that the temperature of the first target room is slowly adjusted to be within the preset temperature range, the comfort of people can be improved, the water temperature value of the air conditioner can be adjusted to be within the preset temperature range without being adjusted by a large margin through the heat exchange module, energy can be saved, and the air conditioner is more environment-friendly.
In an embodiment of the present invention, after "controlling the new blower to start and control the vent opening of the first target room" in S102, the passive room blower control method may further include the following steps:
determining the number of adults and the number of children in the first target room;
and adjusting the operating power of the fresh air machine according to the number of adults and the number of children.
In an embodiment of the present invention, the adjusting the operating power of the fresh air machine according to the number of adults and the number of children may include:
calculating the percentage P of increased operating power of the fresh air fan according to the ratio of P to (R1 xv 1+ R2 xv 2)/V; wherein, R1 is adult's quantity, and V1 is the new trend demand that adult corresponds, and R2 is children's quantity, and V2 is the new trend demand that children correspond, and V is the biggest new trend air output of new trend fan.
In the embodiment of the invention, the fresh air volume required by adults and children is different, so that the running power of the fresh air fan can be adjusted according to the number of adults and the number of children in a room. Specifically, the calculation can be performed by the above formula. Wherein V1 may be 30m3V2 may be 15 to 20m3H; the percentage of the operating power increased by the fresh air fan is the percentage of the operating power increased by the fresh air fan in the maximum operating power of the fresh air fan. The percentage of the increased operating power of the new fan and the percentage of the current operating power of the new fan to the maximum operating power of the new fan are added to obtain the percentage of the operating power of the new fan to the maximum operating power of the new fan after adjustment, and the operating power of the new fan is adjusted according to the percentage of the operating power of the new fan to the maximum operating power of the new fan after adjustment. And if the percentage of the adjusted operating power of the fresh air machine in the maximum operating power of the fresh air machine is more than 100%, adjusting the operating power of the fresh air machine to the maximum operating power.
For example, assuming the passive room is a two-room and one-hall room, the maximum fresh air output can be selected to be 250m3A fresh air machine of/h. The fresh air volume in the bedroom is considered by 2 adults and one child, and is more than or equal to 75m3H; the fresh air quantity in the living room is more than or equal to 120m according to the consideration of 3 adults and 2 children3H is used as the reference value. Thus, the percentage of operating power added by the fresh air machine when the bedroom is ventilated is calculated to be approximately 30%, and the percentage of operating power added by the fresh air machine when the living room is ventilated is calculated to be approximately 48%.
Optionally, the passive rooms of different house types can select different fresh air fans with different maximum fresh air output volumes. Exemplarily, the 1-room 1 hall can select the maximum fresh air outlet volume to be 150m3Novel method ofA fan unit; the 2-room 1 hall can select the maximum fresh air outlet volume to be 250m3A fresh air handling unit of/h; the 3-room 1 hall can select the maximum fresh air outlet volume to be 350m3A fresh air handling unit of/h; the 4 rooms and 1 hall can select the maximum fresh air output of 500m3A fresh air handling unit,/h, etc.
Alternatively, the number of adults and the number of children in the first target room may be determined by an infrared detection device or the like.
In an embodiment of the present invention, the method for controlling a passive room ventilator may further include the following steps:
monitoring whether a second target room with an electric air outlet opened exists in the passive room;
and if the passive room has a second target room, controlling the ventilation opening of the second target room to be opened.
The second target room is a room with an electric air outlet in the passive room and the electric air outlet is opened. The electric exhaust outlet may be an electric exhaust fan.
When the electric air outlet is opened, the air is exhausted from the room to the outside, if the air is exhausted for a long time, the phenomenon of slight negative pressure in the room can be caused, and slight discomfort is brought to people. At this point, the vent of the second target room can be opened without starting a new blower. Because the vent is connected with the air inlet channel of the fresh air fan, and the air inlet channel is communicated with the outside, when the vent of a room is opened, outdoor air can enter a second target room through the air inlet channel and the vent without starting the fresh air fan due to the negative pressure phenomenon in the room, so that the negative pressure phenomenon in the room is improved, and people are under normal pressure.
In an embodiment of the present invention, the adjusting the water temperature value of the air conditioner of the first target room according to the heat exchange efficiency of the heat exchange module in S103 may include:
according to Tk1＝β(Tf0-(Tf1+(Tf2-Tf1)η))+Tk2Determining a water temperature value T of an air conditioner of a first target roomk1(ii) a Wherein eta is the heat exchange efficiency of the heat exchange module, beta is a preset coefficient, and Tf0Is the temperature of the first target roomSet value, Tf1Is the outdoor temperature, Tf2Is the current temperature, T, of the first target roomk2Is the current water temperature value of the air conditioner of the first target room.
The temperature set value of the first target room may be a temperature value within a preset temperature range determined according to the preset temperature range, or may be a temperature value set manually.
The higher the heat exchange efficiency of the heat exchange module is, the smaller the adjustment range of the water temperature value of the air conditioner is.
In an embodiment of the present invention, after "adjusting the water temperature value of the air conditioner of the first target room according to the heat exchange efficiency of the heat exchange module" in S103, the passive room air conditioner control method may further include:
when the temperature of the first target room is monitored to be within a preset temperature range, controlling an air conditioner of the first target room to be closed;
when the carbon dioxide concentration of the first target room is monitored to be less than or equal to a second preset carbon dioxide concentration threshold value, controlling a ventilation opening of the first target room to be closed;
and when the carbon dioxide concentrations of all rooms of the passive room are monitored to be less than or equal to a second preset carbon dioxide concentration threshold value, controlling the fresh air fan to be closed.
In the embodiment of the invention, when the temperature of the first target room is monitored to be within the preset temperature range, the air conditioner of the first target room is closed, and the step of monitoring whether the current temperature of the first target room is within the preset temperature range is skipped to be executed circularly.
And controlling the ventilation opening of the first target room to be closed when the carbon dioxide concentration of the first target room is monitored to be less than or equal to the second preset carbon dioxide concentration threshold value. When the ventilation openings of all rooms are closed, the fresh air machine can be controlled to be closed. The second preset carbon dioxide concentration threshold is a lower limit value of the carbon dioxide concentration, and when the indoor carbon dioxide concentration is lower than the second preset carbon dioxide concentration threshold, a person is in an uncomfortable environment, and the ventilation opening in the room needs to be closed to prevent the indoor carbon dioxide concentration from being further reduced.
And when the carbon dioxide concentration of all rooms of the passive room is monitored to be less than or equal to the second preset carbon dioxide concentration threshold, controlling the new fan to be closed, and skipping to the step of monitoring whether the carbon dioxide concentration of each room of the passive room is greater than the first preset carbon dioxide concentration threshold to be executed in a circulating mode.
