Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit, wherein the air conditioner outdoor unit may refer to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in an indoor unit or an outdoor unit.

An indoor unit 100 of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 3, including: an air conditioner main body 110 and a fresh air module 120.
Specifically, the air conditioner main body 110 has a rectangular parallelepiped shape and has an air inlet and an air outlet, and an air conditioning duct is provided in the air conditioner main body 110. The air-conditioning duct communicates with the air inlet and the air outlet, the air-conditioning main body 110 has a cooling or heating function, and air flow with a low temperature or air flow with a high temperature in the air-conditioning duct flows in the air-conditioning duct and can flow out from the air outlet.
Fresh air can enter the indoor environment from the outdoor through the fresh air module 120, so that fresh air can be injected into the indoor environment. The fresh air module 120 is located at an end of the air conditioner main body 110, and the fresh air module 120 is connected to the air conditioner main body 110. It should be noted that the fresh air module 120 may be disposed at one end of the air conditioner main body 110, and includes, but is not limited to, one fresh air module 120. That is, the fresh air modules 120 may be respectively disposed at two ends of the air conditioner main body 110 to improve the fresh air function of the air conditioner indoor unit 100. The fresh air module 120 is provided with a fresh air duct therein, and the fresh air duct and the air conditioning duct are independent from each other. When the air conditioning indoor unit 100 is in the operating state, the air flow in the air conditioning duct and the air flow in the fresh air duct do not interfere with each other.
It should be noted that, when the air conditioning indoor unit 100 is in an operating state for a long time, the indoor environment is in a sealed state for a long time, and the indoor air becomes dry, which causes discomfort to the user. The fresh air module 120 can be used for exchanging outdoor air and indoor air to introduce outdoor airflow into the room, and can also be used for appropriately neutralizing cold air or hot air generated by the indoor unit 100 of the air conditioner to improve the comfort of the air conditioner.
The fresh air duct has a fresh air outlet 122, the fresh air outlet 122 is communicated with an indoor environment, the fresh air module 120 comprises a fresh air pipeline 123, one end of the fresh air pipeline 123 is communicated with the outdoor environment, the other end of the fresh air pipeline 123 is communicated with the fresh air duct, a rectifying grating 124 is arranged in the fresh air pipeline 123, and the rectifying grating 124 is provided with a plurality of filtering holes 125 so as to be suitable for filtering and rectifying air flow flowing through the fresh air pipeline 123.
Particularly, a plurality of filtering holes 125 are formed in the rectifying grating 124, and the filtering holes 125 can not only filter sundries in the fresh air, but also block the flow of the fresh air in the fresh air pipeline 123 so as to reduce the speed and rectify the fresh air.
According to the utility model discloses an indoor set of air conditioner 100 is through being equipped with the rectification grid 124 that can filter and commutate the new trend in new trend pipeline 123 for when the new trend flows in new trend pipeline 123, the probability that produces vortex and backward flow reduces, thereby reduces the new trend at new trend pipeline 123 noise that flows, and then can promote the user performance when using indoor set of air conditioner 100.
As shown in fig. 2, in some embodiments, the rectifying grill 124 is provided in plurality, and the plurality of rectifying grills 124 are spaced apart along the length of the fresh air duct 123.
