The fresh air exchange system that is popular in the Chinese market uses fresh air ducts, air outlets, and related accessories to realize two-way ventilation indoors and outdoors, and sends outdoor fresh air into the room at the same time. , and also discharge indoor dirty air to the outside, but because the fresh air system needs to arrange and install pipes, it is very inconvenient for the houses that have already moved in, so it is difficult to popularize. In recent years, a variety of wall-mounted fresh air fans have appeared, such as the air intake and exhaust systems produced by Guangdong Panasonic, which pair the air intake and exhaust, install them separately, and control them separately. These fresh air fans do not need ducts, but they have a unique function: they are only designed to remove indoor pollution. The fresh air system or fresh air blower mentioned above does not take into account the linkage with the existing indoor air conditioner, that is, while realizing the fresh air function, it is completely possible to use the fresh air whose outdoor night temperature has dropped significantly to cool the room in summer. In fact, in many parts of our country, the temperature difference between day and night in summer is about 10°C. As a family room is mainly used at night, fresh air can be introduced to cool down, which greatly reduces the workload of the air conditioner and saves electricity. "Air-conditioning disease" troubles, life is healthier.

Here are some examples:

1. Fresh air function: Set the system to the "fresh air" function through the setting key set on the remote control 7 or the fresh air outlet 2, and set the air volume and select whether to set the timing. The grille is opened, and the outdoor fresh air enters from the ventilation hole and is filtered by the purification unit 4, then flows out from the air grille and enters the 1# bedroom. At the same time, the exhauster 6 discharges the dirty air in the bedroom 1 to the outside. It circulates continuously inside, and its function is exactly the same as that of the current fresh air system, which can be used in four seasons.

2. Energy saving and cooling function: In summer, the temperature difference between day and night is about 10°C. In summer night, the system can be set to "energy saving and cooling" function by setting the key set, and set the stop temperature value of the air conditioner and the start temperature value of the intake fan and exhaust fan. Generally, the door 16 is closed when we sleep. If the set temperature of the air conditioner is 26°C when falling asleep, the temperature value can also be set to 26°C when the air conditioner of the present utility model is shut down. The temperature value is 27°C. The control module 3 analyzes the temperatures detected by the indoor temperature sensor 13 and the outdoor temperature sensor 14 respectively through the microcomputer chip and compares them with the set air-conditioning shutdown temperature value and the start-up temperature value of the air inlet fan and the air exhauster. When the outdoor temperature drops to 26 °C, the control module 3 controls the air conditioner to enter the shutdown state through the AC contactor of the air conditioner switch circuit. The indoor temperature rises gradually due to the shutdown of the air conditioner. When the indoor temperature rises to 27°C, the control module 3 starts the intake fan 1 and the exhauster 6 and simultaneously opens the air grille. The outdoor fresh air enters through the ventilation hole and is filtered by the purification unit 4. It flows out from the air grid and enters the 1# bedroom. At the same time, the air exhauster 6 discharges the air in the bedroom 1 to the outside. In this way, a large amount of fresh air circulates continuously in the bedroom, and the circulation and exchange of indoor and outdoor air make Cool down the room.

3. Safe pollution discharge function: The gas probe set 15 continuously detects indoor harmful gases by itself. Once the indoor harmful gas pollution exceeds the standard, the control module 3 will start the intake fan 1, the exhaust device 6, and open the air grille to introduce fresh air at the same time The indoor harmful air is exhausted through the exhaust device, which ensures the safety of the indoor air environment.
