Open windows for ventilation

My friend came to visit at home the day before yesterday,
The living room is pretty hot,
I opened both the front window and the side windows,
As a result, the friend closed the front window again.

He says:
The temperature of the wind in front is higher than the indoor temperature, so do not open the window.
The temperature of the wind on the side is lower than that in the room, should be turned on.

My home is a side house, with the big road in front and a small alley on the side.

My friend said that when the wind temperature is higher than room temperature, opening the window will make the room temperature higher.

I stood by the front window and felt it, the wind is hot；
Standing in front of the side window, the wind is cool, which is really strange.

I haven't noticed it before, it is so as.

I’m guessing, maybe it’s the side alley, which has very little air-conditioning, and there are buildings to block the sun, so it’s a cool breeze;
The front is because of the main road, there are many vehicles and the air-conditioning of the building is installed on this side, which emits a lot of hot air, so the wind on the front becomes particularly hot.

打开窗户来通风

前天朋友来家里拜访，
客厅蛮热的，
我把前面的窗户和侧边的窗户都给打开，
结果朋友又把前面的窗户给关了起来。

他说：
前面的风，其温度比室内还要高，不要打开窗。
侧边的风，其温度比室内还要低，要开这个。

我家是边间户，前面是大马路，侧边是一条小巷子。

朋友说，当风的温度高于室温的时候，开窗反而会让室温更高。

我站在前窗的地方，感受了一下，风是热的，
站在侧窗前，风是凉风，真的是蛮奇特的。

以前都没注意过，想说，热就是开窗来吹风就是了的，不知道有朋友讲的那种情况。

我在猜，可能是侧边的这条巷子，装设的冷气很少，又有大楼来挡住阳光，所以是凉风；
前面则是因为大马路，车辆多且大楼的冷气都装在这一边，排放了大量的热气，所以正面的风，变的特别的热。
