Embodiment 1

[0033] figure 1 It is a flowchart of the fresh air machine anti-condensation control method according to Embodiment 1 of the present invention, as figure 1 As shown, the method includes the following steps:

[0034] Step S101, determining the outdoor dew point temperature in the current environment;

[0035] Among them, an organic external temperature and humidity detector is installed on the outside of the fresh air machine. After starting up, start the external temperature and humidity detector at a preset interval (for example, 60s) to detect the ambient temperature and air humidity in the current environment; The line graph determines the dew point temperature. figure 2 is a condensation line graph according to an embodiment of the present invention, such as figure 2 Shown is the relationship between the ambient temperature and air humidity and the dew point temperature. The controller in the fresh air machine combines the condensation line graph to directly determine...

Embodiment 2

[0045] This embodiment provides a new fan, image 3 is a structural schematic diagram of a new fan according to an embodiment of the present invention, such as image 3 As shown, one or more moisture-proof boards are arranged on the fresh air machine: the moisture-proof boards are arranged in the air duct and located between the core body and the air inlet. The moisture-proof board can be a flat plate, or a board structure with a preset angle. On the side of the outdoor air inlet, an organic external temperature and humidity detector is installed, and an organic internal temperature and humidity detector is installed inside the fresh fan. There are at least two moisture-proof boards, and multiple moisture-proof boards can be arranged side by side. image 3 The moisture-proof boards in 3 are illustrated as an example, and they are arranged side by side under the core. After the moisture-proof board is raised, it can filter the fresh air, reduce the air humidity and avoid con...

Embodiment 3

[0047] When the present invention is actually implemented, when the fresh air blower is turned on, the temperature and humidity of the outdoor air are detected, and the real-time dew point temperature is calculated according to the condensation line graph. When the temperature of the core reaches the temperature required for the dew point, the moisture-proof plate is started to rise , according to the range where the detected humidity is located, the moisture-proof boards are raised correspondingly to filter the fresh air, so that the air humidity is reduced until the temperature of the core body cannot produce condensation.

[0048] Figure 4 It is a flow chart of the fresh air machine anti-condensation control method according to Embodiment 2 of the present invention, as Figure 4 As shown, the method includes the following steps:

[0049] After starting up, turn on the outside air temperature and humidity detector with a delay of 60 seconds, and send the detected outside a...

Abstract

The invention discloses a fresh air fan anti-condensation control method, device and air conditioner. Wherein, the method includes: determining the outdoor dew point temperature in the current environment; detecting the core body temperature of the fresh air machine, and judging whether the core body temperature is within the preset range of the dew point temperature; if so, controlling the moisture-proof plate of the fresh air machine Raise, if not, keep the moisture barrier still. The invention controls the rise and fall of the moisture-proof plate of the fresh air machine through the comparison of the dew point temperature and the temperature of the core body, thereby avoiding condensation in the fresh air machine, protecting the heat exchange membrane of the core body, and ensuring the heat exchange efficiency of the heat exchange film.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an anti-condensation control method and device for fresh air fans, and an air conditioner. Background technique [0002] The heat exchange membrane used in the core of the current fresh air fan is not anti-condensation. Once the temperature and humidity of the air in the environment reach the dew point, the heat exchange membrane of the core will produce condensation. Moreover, there is no water receiving tray on the existing fresh air blower at all, and the condensation generated cannot be discharged. However, even if there is a water tray, the water generated by condensation has already affected the heat exchange membrane and affected the heat exchange efficiency. [0003] For the problem in the prior art that the condensation generated by the fresh air fan affects the heat exchange membrane, no effective solution has been proposed so far. Contents of the in...
