Does the air conditioner need to be equipped with a rain awning?

In order to protect air conditioners, many users install rainproof awnings on the outdoor units of air conditioners. Even in order to shelter from the wind and rain, some air outlets were blocked. This will affect the heat dissipation of the air conditioner, thus affecting the cooling effect. There is a lot of dust attached to the heat sink of the outdoor unit. If there is no canopy, the rain will be washed away to ensure the cooling and heat dissipation effect. Therefore, if it is not directly exposed to air conditioning, there is absolutely no need to install a rain awning.
