随着夏季高温天气的来临,发电机组应用过程中如何为机房散热与降噪成为关注的焦点。

With the advent of high temperature in summer, how to dissipate heat and noise in the generator room has become the focus of attention.

第一,一般在设计机房降噪时,应考虑机房的通风量,通风量是根据发动机燃烧所需的空气量和机组散热所需的换气量来计算的,燃气量与换气量之和便是机房的通风量。这是一个变化值,是随机房的温升而变化。在考虑机房降噪时,应当按照比较严格的标准来计算机房的通风量,也就是机房温升控制在5℃以内,机组所需的通风量最大。

First, when the noise reduction is designed in the machine room, the ventilation volume of the machine room should be considered. The volume of ventilation is calculated according to the amount of air required by the engine burning and the amount of air exchange required by the unit. The sum of gas and air exchange is the ventilation of the machine room. This is a change value, which is the temperature rise of random rooms. When considering the noise reduction in the machine room, the ventilation volume of the computer room should be taken according to the strict standard, that is, the temperature rise of the machine room is controlled within 5 degrees C, and the ventilation volume required by the unit is the greatest.

第二,要根据通风量和机房进排风消声器的最低空气流速,即可计算出进排风口的截面积,据此设计的进排风口在一般的情况下都能满足机房的散热要求。诚然,这是比较高的标准,代价也较高,需要专业的降噪厂商进行设计和施工,能同时满足理想的降噪效果和充分的散热条件。

Second, according to the ventilation rate and the minimum air flow velocity of the exhaust muffler, the section area of the inlet and outlet can be calculated. According to this, the design of the inlet and outlet tuyere can meet the heat dissipation requirements of the machine room. Indeed, this is a relatively high standard, and the cost is high. It needs professional noise reduction manufacturers to design and construct, and can meet the ideal noise reduction effect and sufficient heat dissipation conditions at the same time.

第三,机房的降噪和散热与用户的要求也有关系,用户可根据环境温度的变化,对降噪与散热有不同的侧重。比如在冬天时,可适当追求降噪方面的效果;在炎热的夏季,为满足机房的充分散热,在降噪方面作出些让步。

Third, the noise reduction and heat dissipation of the computer room are also related to the requirements of users. Users can have different emphasis on noise reduction and heat dissipation according to the change of ambient temperature. For example, in winter, we can appropriately pursue the effect of noise reduction; in the hot summer season, in order to meet the full heat dissipation of the computer room, we should make some concessions in reducing noise.

尤其是夏季的到来,保证机房通风散热效果良好是最重要的一点,大家可以从现在开始着手准备,为发电机组处于一个安静安全的运行环境,保证发挥最佳效果,也为作业安全增添一份保障。

Especially in summer, it is the most important point to ensure the good ventilation and heat dissipation of the machine room. We can start from now on, in a quiet and safe operating environment for the generator set, ensure the best effect, and add a guarantee for the safety of the operation.
