Problems solved by technology

There are also some all-in-one fresh air conditioners that also use a fan to inhale fresh air, but because they also absorb indoor air when controlling the fresh air system to inhale fresh air, in order to increase the amount of fresh air intake, it is necessary to increase the speed of the fan. increase negative pressure
[0004] The use of two fans has the following defects. First, since the fresh air system and the air conditioner form an integrated machine, the fans of the fresh air system will not be far away from the area where people rest, so the noise generated by the fresh air fan will directly affect people’s rest. Second, the use of two fans will lead to an increase in the overall energy consumption of the fresh air air conditioner, which in turn increases the cost of use
[0005] The use of one fan has the following defects. First, by increasing the fan speed to increase the air intake of the fan, the utilization rate of the fan is low.
The second point is that increasing the speed of the fan will inevitably increase the noise of the fan and affect the rest of the indoor personnel.

Embodiment 1

[0050] see figure 1 , figure 1 A schematic structural view of the integrated fresh air air conditioner provided by the present invention is shown.

[0051] The all-in-one fresh air conditioner includes a housing 110 , a wind mechanism 120 , a temperature adjustment mechanism 130 and a fresh air mechanism 140 . The wind force mechanism 120, the fresh air mechanism 140 and the temperature adjustment mechanism 130 are all fixedly arranged in the housing 110; the air inlet of the fresh air mechanism 140 communicates with the outdoor fresh air; the air outlet of the fresh air mechanism 140 is arranged in the The negative pressure zone generated by the rotation of the wind force mechanism 120 is suitable for sucking the outdoor fresh air communicated with the fresh air mechanism 140 into the wind force mechanism 120 through the negative pressure generated by the negative pressure zone; the temperature adjustment mechanism 130 is arranged in the negative pressure zone, And it is su...

Embodiment 2

[0065] see Figure 7 , Figure 7 This embodiment provides a block diagram of the circuit structure of the control device of the all-in-one fresh air conditioner as provided in Embodiment 1.

[0066] The control device of the all-in-one fresh air conditioner includes: a control module, a detection module, a refrigeration module, a heating module, a wind power module, a drive module, and a signal receiving module. The detection module, the cooling module, the heating module, the wind power module, the driving module, and the signal receiving module are respectively electrically connected to the control module.

[0067] The control module is suitable for controlling the refrigeration module, the heating module, the wind module and the driving module to work according to the instructions received by the signal receiving module.

[0068] The signal receiving module is used for receiving instructions.

[0069] The cooling module is used to cool the air.

[0070] The heating modu...

Embodiment 3

[0078] see Figure 8 , the present invention also provides a control flow of the integrated fresh air air conditioner as provided in Embodiment 1 or Embodiment 2, as follows:

[0079] S1: Receive control instructions;

[0080] S2: Determine the type of the control command. If the type of the control command is not related to the fresh air system, go to S3. If the control command is related to the fresh air system, go to S4.

[0081] S3: According to the control instruction, adjust the air conditioner part, go to S7.

[0082] S4: Determine whether the control instruction is to turn on or turn off the fresh air system.

[0083] S5: If the judgment result is to open the fresh air system, then control the drive module to make the motor in the drive assembly 114 rotate forward, lower the push rod 114b, close the air inlet deflector 111b, and check whether the wind power module is working at the same time, if so, go to S7 , if not, control the wind power module to drive the wind ...

Abstract

The invention provides a fresh air conditioner all-in-one machine, a working condition detection method and a switching method, and belongs to the field of heating and ventilation. A fresh air mechanism can suck external fresh air into the fresh air conditioner all-in-one machine through negative pressure generated in a negative pressure area, and meanwhile, the fresh air and indoor air are switched through an air admission guide plate, and when the fresh air needs to be replaced, all the negative pressure generated by a wind power mechanism is used for sucking the fresh air. On one hand, thenumber of fans is reduced, so that noise generated during operation of the fans is reduced; on the other hand, due to the fact that the fresh air mechanism is not provided with the fans, the size of the fresh air mechanism can be further reduced, the overall size of the fresh air conditioner all-in-one machine is reduced, and the fresh air conditioner all-in-one machine is more compact in structure; and meanwhile, when the air conditioner function of the fresh air conditioner all-in-one machine operates, the fresh air and the indoor air are switched through the air admission guide plate, the fresh air is replaced through the fresh air mechanism at the moment, the negative pressure generated by the wind power mechanism does not need to be increased, energy consumption of the fresh air mechanism is avoided, and energy is saved.

Description

technical field [0001] The invention relates to the field of heating and ventilation, in particular to an integrated fresh air air conditioner, a working condition detection method and a switching method. Background technique [0002] Fresh air system and air conditioner are two kinds of indoor HVAC equipment that are indispensable at present. Purchasing the two kinds of equipment at the same time will increase the purchase cost on the one hand. On the other hand, when the fresh air system is designed and installed, the air intake duct will It is not convenient to install fresh air in houses that have been decorated. [0003] In the prior art, some all-in-one fresh air conditioners simply combine the fresh air system and the air conditioner to form an all-in-one fresh air conditioner. When the all-in-one fresh air conditioner is working, the fresh air is introduced into the room from the outside, and the air conditioner still performs internal circulation, that is Both the ...
