In this embodiment, the condensation generating condition is that there is a temperature difference in the space, and therefore, the pipe wall temperature of the fresh air pipe and the indoor dew point temperature can be used as a condition for judging the generation of condensation, wherein the dew point temperature is defined as the temperature when the air is cooled to saturation under the condition that the water vapor content and the air pressure are not changed, that is, the temperature when the water vapor in the air becomes dew.
In this embodiment, after the fresh air conditioner is started, according to an operation instruction of a user, the fresh air conditioner opens the fresh air mode and performs heating operation at the same time. Optionally, a first temperature sensor is arranged in the fresh air duct, and the first temperature sensor can be used for detecting the real-time temperature of the wall position of the fresh air duct. Therefore, the wall temperature of the fresh air duct acquired in step S201 may be the real-time temperature of the fresh air duct wall position detected by the first temperature sensor. The first temperature sensor transmits the detected pipe wall temperature to the processor 100 through wireless communication or wired communication. Alternatively, the first temperature acquisition frequency may set an acquisition period or an acquisition at irregular intervals.
In this embodiment, a dew point temperature sensor is provided at the indoor side, and the dew point temperature sensor is used for detecting the real-time dew point temperature in the room. The dew point temperature sensor sends the detected real-time dew point temperature to the processor 100 through wireless communication or wired communication; the processor 100 compares the pipe wall temperature with the indoor dew point temperature, and then controls the running state of the fresh air conditioner, so that the fresh air conditioner keeps the best running state, and meanwhile, the pipe wall of the fresh air pipe is prevented from generating condensation. Alternatively, the dew point temperature acquisition frequency may set the acquisition period or acquisition at irregular times.
Optionally, in the above embodiment, the tube wall temperature is an inner wall temperature or an outer wall temperature.
In the embodiment, the temperature sensor acquires the temperature of the inner wall of the fresh air pipe. The inner wall of the fresh air pipe is the air outlet part and is also the position communicated with the indoor space. Therefore, condensation is most likely to occur on the inner wall of the fresh air duct. The inner wall temperature of gathering the fresh air pipe is close to the holistic intraductal temperature of fresh air pipe more, and treater 100 contrast pipe wall temperature and indoor dew point temperature, control fresh air conditioner's that can be more accurate running state.

When the temperature sensor is insensitive and needs to be replaced and maintained, the temperature sensor is arranged on the outer wall of the fresh air pipe and is easy to replace and maintain.
Optionally, as shown in fig. 3, determining the indoor dew point temperature includes:
s301, detecting indoor temperature and indoor humidity;
s302, calculating the indoor dew point temperature according to the indoor temperature and the indoor humidity.
In this embodiment, in order to obtain the indoor dew point temperature more accurately, the indoor dew point temperature can be obtained by calculating the indoor temperature and the indoor humidity. A second temperature sensor and a humidity sensor are arranged on the indoor side, and the second temperature sensor and the humidity sensor can also be temperature and humidity sensors. Here, taking an example that a second temperature sensor and a humidity sensor are disposed at an indoor side, the second temperature sensor detects and acquires an indoor temperature, the humidity sensor detects and acquires an indoor humidity, and sends the detected indoor temperature and the detected indoor humidity to the processor 100 through wireless communication or wired communication, in a temperature value interval where the indoor temperature is [0 ℃, 60 ℃), and the indoor relative humidity is a humidity percentage value interval of [ 0%, 100% ], the processor 100 obtains an indoor dew point temperature according to the following formula:
Figure BDA0003567439800000061
Figure BDA0003567439800000062
wherein T and the dew point temperature TdThe unit is the temperature, relative humidity RH is percentage, ln is the natural logarithm, and the constant a is 17.27; the constant b is 237.7 ℃.

In this embodiment, the first temperature sensor, the second temperature sensor and the humidity sensor are used to obtain various temperature parameters, and finally obtain the indoor dew point temperature and the pipe wall temperature. Here, processor 100 compares the room dew point temperature to the tube wall temperature. If the indoor dew point temperature is higher than the temperature of the pipe wall, the indoor air enters the fresh air pipe; the temperature of the pipe wall is low, condensation is easy to generate, and then the processor controls the fresh air conditioner to increase the running frequency of the compressor and reduce the rotating speed of the indoor fan. The temperature of the refrigerant in the on-line pipe is increased, so that the temperature in the fresh air pipe is increased, particularly the temperature of the wall of the fresh air pipe is increased, and condensation in the fresh air pipe is prevented.
Optionally, the operating frequency of the compressor is increased, so that the temperature of the refrigerant can be increased. For a smoother compressor operation, for example, each increase of 5hz, 10hz, 15hz, etc. may be set in conjunction with the actual demand.
Optionally, the rotating speed of the indoor fan is reduced, so that the heat exchange rate between the indoor heat exchanger and the indoor environment can be reduced, and more heat can be reserved in the refrigerant. In order not to affect the user feeling, for example, the set rotation speed may be reduced by 50rpm, 100rpm, 150rpm, etc. each time, and may be set in combination with the actual demand.

In this embodiment, the preset time period is a critical time period for determining whether condensation is generated on the wall of the fresh air duct. Namely, when the indoor dew point temperature is continuously higher than the pipe wall temperature and does not reach the preset time length, the pipe wall of the fresh air pipe has no risk of generating condensation; at the moment, the fresh air conditioner keeps the current running state to run; when the indoor dew point temperature is continuously higher than the pipe wall temperature and reaches the preset time length, the pipe wall of the fresh air pipe has the risk of generating condensation, and the fresh air conditioner needs to perform condensation prevention control. The fresh air machine of the fresh air conditioner is controlled to stop running in time, and condensation generated in the fresh air pipe is prevented from blowing indoors.
