Problems solved by technology
[0004] After the fresh air device is introduced into the current air conditioner indoor unit, when the fresh air function is used, the amount of air for heat exchange will increase. Under the premise that the cooling / heating capacity of the air conditioner remains unchanged, it will take longer for the air conditioner to reach the user's setting when it is running. The temperature will make the cooling / heating effect worse, thus affecting the user experience

Embodiment Construction
[0043] figure 1 It is an overall schematic diagram of the fresh air conditioner indoor unit 10 according to an embodiment of the present invention. from figure 1 It can be seen from the figure that the fresh air conditioner indoor unit 10 provided by the present invention includes a fresh air device 200 in addition to the indoor unit 10 having the same appearance and performance as in the prior art. Specifically, the indoor unit 10 includes a casing 100, a blower fan (not shown in the figure) and a main heat exchanger (not shown in the figure) are arranged inside the casing 100, and a The air inlet 110, the lower part of the casing 100 forms an air outlet (not shown in the figure). Indoor air is introduced into the interior of the indoor unit 10 from the air inlet 110 through the air supply fan, and after heat exchange (cooling or heating) by the main heat exchanger, the heat-exchanged air is then introduced into the room from the air supply port, and the circulation in this...

The present invention provides a fresh air air conditioner indoor unit, which includes a casing and a fresh air device, the fresh air device is arranged at one end of the casing, and includes an air inlet module and a fan module connected to the air inlet module; the inside of the air inlet module defines In the air inlet chamber, there is an air inlet at the lower and rear of the air inlet module, which is used to introduce outdoor air into the air inlet chamber; the fan module sends the outdoor fresh air introduced by the air inlet module into the room, and the inside of the air outlet of the fan module is equipped with a purification module. The lower part of the purification module is provided with a secondary heat exchanger. The fan module of the fresh air device of the present invention is provided with a secondary heat exchanger. After the fresh air function runs, the amount of air that needs to be exchanged by the air conditioner during heating / heating increases, and it takes longer to reach the set temperature. The auxiliary heat exchanger is installed in the device to cool / heat the fresh air entering the room in advance, which can effectively improve the heat exchange effect of the air conditioner and improve the comfort of users when using it.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a fresh air air conditioner indoor unit. Background technique [0002] An air conditioner is a widely used household appliance. It generally has heating and cooling functions. When the ambient temperature is too low or too high, it can adjust the temperature of the indoor air to provide users with a suitable indoor environment and effectively improve the air conditioner. Quality of life of users. [0003] However, because the current air conditioners only circulate the indoor air to heat or cool down when heating or cooling, and the user will close the door of the living room at the same time in order to maintain the indoor temperature, so that the indoor air quality will be reduced. It will gradually deteriorate, which will adversely affect the user's health. In particular, in recent years, air pollution has been increasing day by day, especially in the winter heating season, and people a...
