With the rapid development of economy, people's living standards have gradually improved, villas began to prevail gradually, most of the villas now have basements. What are the uses of the basement ventilation equipment? Here's a brief introduction.

　　1 排風機(也叫新風機)：把地下室的空氣排到戶外，地下室形成了負壓，樓上和戶外的空氣再流入地下室。

　　1 exhaust fan (also known as fresh fan): the basement air is discharged outdoors, the basement forms a negative pressure, upstairs and outdoor air flow into the basement.

　　2 送風機(也叫新風機)：把戶外的空氣向地下室送入，地下室形成正壓，地下室的空氣向戶外滲出或流出。

　　2. Blower (also known as fresh air): Put outdoor air into the basement, the basement forms a positive pressure, and the air in the basement seeps out or flows out to the outside.

　　送風機與排風機是通用的，正向安裝是送風，反方向安裝是排風，其作用一樣的。

　　The air supply fan and exhaust fan are universal, the forward installation is the air supply, and the reverse installation is the air exhaust, which has the same function.

　　3 新風換氣機(能量回收功能)：除了包含一個排風機和一個送風機，還必須包含能量回收功能(熱回收裝置)。送風機在工作的同時，排風機也在工作，并且把排出的空氣里的能量(夏天的冷量，或者冬天的熱量)回收回來，傳遞給送風機向地下室送的新風里，這樣比較節約能源，降低使用費。

　　Fresh air exchanger (energy recovery function): In addition to including an exhaust fan and a blower, it must also include energy recovery function (heat recovery device). While the blower is working, the exhaust fan is also working, and the energy from the exhausted air (summer cooling, or winter heat) is recovered and transmitted to the fresh air that the blower delivers to the basement, which saves energy and reduces the cost of use.

　　地下室的空氣一般比較污蝕而且非常潮濕，在夏天遇見空氣濕度較高的情況下，會在地下室較涼的地方結露，比如在地

　　The air in the basement is usually dirty and very humid. When the air humidity is high in summer, it will dew in the cooler part of the basement, such as in the ground.

　　板上，在頂棚上，會有一層水珠。所以非常有必要安裝排風機或者是送風機，送風機和排風機在商業上一般也叫新風機

　　On the board, on the ceiling, there will be a layer of water droplets. Therefore, it is very necessary to install exhaust fans or air blowers. Air blowers and exhaust fans are also called fresh air blowers in commerce.
