Embodiment
With reference to shown in referring to Fig. 1 to Fig. 4, according to an embodiment of the invention, indoor set includes air inlet 1 and heat exchanger 2, enters
The scope of ratio S1/S2 between effective the incoming air area S1 and heat exchanger 2 in air port 1 heat exchange area S2 is 0.22~0.29.
Generally, due to heat exchanger 2 has the wind shielding structures such as heat exchanger tube above, therefore, when the heat exchange area of heat exchanger 2
When designing unreasonable, it is easy for causing the intake of air inlet 1 to match with the heat exchange amount of heat exchanger 2, when intake is more than
It during the heat exchange amount of heat exchanger 2, may result in that the heat exchange of air and heat exchanger 2 is insufficient, reduce the heat exchange property of heat exchanger 2, make
Obtaining air can not fully be exchanged heat, and when intake is less than the heat exchange amount of heat exchanger 2, may result in the heat exchanger 2 of heat exchanger 2
Performance can not be fully used, and reduce the utilization ratio of heat exchanger 2, and by effective incoming air area S1 of air inlet 1 with changing

Therefore, when the spacing between heat exchanger 2 and air-inlet grille 3 is smaller, in order to ensure effective incoming air area and heat exchange
The heat exchange area of device 2 matches, it is necessary to makes the ratio between the heat exchange area of effective incoming air area and heat exchanger 2 smaller, makes
Air is obtained during quick flowing, heat exchanger 2 there are enough heat exchange areas fully to change the air for flowing through heat exchanger 2
Heat；When spacing between the air-inlet grille 3 of heat exchanger more than 2 is larger, in order to ensure the heat-transfer surface of effective incoming air area and heat exchanger 2
Product match, it is necessary to make the ratio between the heat exchange area of effective incoming air area and heat exchanger 2 larger so that air with compared with
During jogging speed flows, heat exchanger 2 has enough heat exchange areas fully to exchange heat the air for flowing through heat exchanger 2, and
So that the heat exchange area of heat exchanger 2 is more fully utilized, the heat exchange property and utilization ratio of heat exchanger 2 are improved.
Preferably, L scope is 25mm to 30mm, can cause the minimum spacing ratio between heat exchanger 2 and air-inlet grille 3
Relatively rationally, the relation between the heat exchange area of effective incoming air area and heat exchanger can be more fully balanced, improves air conditioner
Service behaviour.
