隨著夏季高溫天氣的來臨,發電機組應用過程中如何為機房散熱與降噪成為關注的焦點。

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

D88尊龙,一般在設計機房降噪時,應考慮機房的通風量,通風量是根據發動機燃燒所需的空氣量和機組散熱所需的換氣量來計算的,燃氣量與換氣量之和便是機房的通風量。這是一個變化值,是隨機房的溫升而變化。在考慮機房降噪時,應當按照比較嚴格的標準來計算機房的通風量,也就是機房溫升控制在5℃以內,機組所需的通風量大。

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.

D88尊龙第二,要根據通風量和機房進排風消聲器的低空氣流速,即可計算出進排風口的截面積,據此設計的進排風口在一般的情況下都能滿足機房的散熱要求。誠然,這是比較高的標準,代價也較高,需要的降噪廠商進行設計和施工,能同時滿足理想的降噪效果和充分的散熱條件。

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,機房的降噪和散熱與用戶的要求也有關系,用戶可根據環境溫度的變化,對降噪與散熱有不同的側重。比如在冬天時,可適當追求降噪方面的效果;在炎熱的夏季,為滿足機房的充分散熱,在降噪方面作出些讓步。

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.

尤其是夏季的到來,保證機房通風散熱效果良好是重要的一點,大家可以從現在開始著手準備,為發電機組處于一個安靜安全的運行環境,保證發揮佳效果,也為作業安全增添一份保障。

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.
