Embodiment 1

[0045] Such as figure 1 Shown is a flow chart of the comfort air supply control method of the present invention. The fresh air air conditioner of the present invention first receives an operation instruction, and the operation instruction includes the operation instruction of the air-conditioning mode, the operation instruction of the fresh air mode, and the instruction of simultaneous operation of the fresh air mode and the air-conditioning mode: when receiving the operation instruction of the air-conditioning mode, only open The air-conditioning mode; when receiving the instruction to run the fresh air mode and the air-conditioning mode simultaneously, open the fresh air mode and the air-conditioning mode at the same time, but will not enter the comfortable air supply control method of the present invention; when only receiving the instruction to run the fresh air mode, enter Comfortable air supply control method of the present invention;

[0046] Specifically, the comforta...

Embodiment 2

[0061] The difference between this embodiment and Embodiment 1 is that the steps after turning on the air-conditioning mode to exchange heat with the indoor wind include:

[0062] Obtain the set temperature of the fresh air conditioner, the set temperature is the desired indoor ambient temperature set by the user; periodically detect the difference between the indoor ambient temperature and the set temperature, and according to the The difference between the indoor ambient temperature and the set temperature controls the closing of the air-conditioning mode.

[0063] Specifically, when the air-conditioning mode is the cooling mode, it is judged whether the indoor ambient temperature is less than or equal to the set temperature of the fresh air air conditioner, and if so, the air-conditioning mode is turned off; this is because in the cooling mode, due to The sudden drop in the outdoor ambient temperature makes the temperature of the introduced outdoor air lower. If the indoor ...

Embodiment 3

[0066] Embodiment 3 of the present invention discloses a fresh air conditioner, see figure 2 , the indoor unit of the fresh air air conditioner is a cabinet-type air conditioner indoor unit, and the housing of the air conditioner indoor unit includes a front panel 400, a rear panel 500 and a chassis 600, and is arranged on the front panel 400 and the rear panel 500. The indoor air duct assembly 200 and the fresh air duct assembly 100.

[0067] Wherein, the indoor air duct assembly 200 forms an indoor air duct 20, the indoor air duct 20 is provided with a heat exchanger 300, and the indoor air inlet 21 of the indoor air duct 20 is arranged on the back panel 500, the The indoor air outlet 22 of the indoor air duct 20 is arranged on the front panel 400, and the indoor air duct assembly 200 can introduce indoor air from the indoor air inlet 21 and force the indoor air to pass through the heat exchanger 300 in the indoor air duct 20 and then flow out from the indoor air duct 20. ...

Abstract

The invention provides a fresh air conditioner and a comfortable air supply control method thereof. The comfortable air supply control method comprises the steps of receiving an operation instructionof a fresh air mode, and starting the fresh air mode; detecting an indoor environment temperature and an outdoor environment temperature; judging whether the absolute value |delta T| of the temperature difference between the indoor environment temperature and the outdoor environment temperature is greater than or equal to a first preset temperature or not; and if yes, automatically starting an airconditioner mode to exchange heat with indoor air, mixing the indoor air subjected to heat exchange with outdoor fresh air, and enabling mixed air to flow into a room. Under the condition that the indoor and outdoor temperature difference is large, the air conditioner mode is automatically started to exchange heat with indoor air, the indoor air subjected to heat exchange through the heat exchanger can be mixed with the introduced outdoor fresh air, the situation that the indoor temperature is too low or too high due to introduction of the outdoor fresh air is avoided, and the comfort degreeof a human body is improved; and no extra heat exchanger needs to be added for heat exchange of the outdoor fresh air, universality is good, and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a fresh air air conditioner and a comfortable air supply control method thereof. Background technique [0002] The air conditioner needs to be used in a closed indoor environment. Since the indoor carbon dioxide concentration will be too high due to long-term lack of ventilation, the fresh air air conditioner came into being. The fresh air air conditioner usually installs a fresh air module on the indoor unit of the air conditioner, and the fresh air module is connected to the outside. The outdoor air is sucked into the fresh air duct of the fresh air module and discharged into the room to improve the indoor air quality. [0003] In summer or winter, when the temperature difference between indoors and outdoors is large, if the fresh air air conditioner directly introduces outdoor air into the room, the local air temperature difference will be too large, which will easily...
