Now our scientific and technological level is constantly improving, and the requirements for product quality are also higher and higher. Let's learn about the role of intercooler of diesel and gas generator set with the technical personnel of Jinan gas generator manufacturer

要提高瓦斯发电机组的输出功率，经济有用的办法就是增加进入气缸的空气量。在瓦斯发电机组气缸容积不变的条件之下，增加进入气缸空气的密度是主要的手段。但是，空气的密度和压力是成正比的，和温度是成反比的，所以，增加进气的压力，降低进气的温度是能够提高进气密度的，目前瓦斯发电机组一般是利用增压器来提高压力的，利用中冷器来降低气体的温度的。

To improve the output power of gas generator set, the economic and useful way is to increase the air volume into the cylinder. Under the condition of constant cylinder volume of gas generator set, increasing the density of air entering the cylinder is the main means. However, the density of air is directly proportional to the pressure and inversely proportional to the temperature. Therefore, increasing the pressure of air intake and reducing the temperature of air intake can improve the density of air intake. At present, gas generator sets generally use supercharger to increase the pressure and intercooler to reduce the temperature of gas.

目前，中高压的瓦斯发电机一般都装有中冷器。中冷器实际上就是个热交换器，它是安装在涡轮增压器与燃烧室之间。当瓦斯发电机组增压器的增压比较高的时候，进气温度也比较高，让空气的密度下降。中冷器是用于冷却增压空气，降低增压之后的进气的温度。增压空气在中冷器中一般可以降低25到60℃。一方面可以提高充气的密度，另一方面可以降低进气的气缸温度与整个循环的平均温度。

At present, medium and high voltage gas generators are generally equipped with intercooler. Intercooler is actually a heat exchanger, which is installed between turbocharger and combustion chamber. When the supercharger of gas generator set is relatively high, the intake temperature is also relatively high, which makes the air density drop. Intercooler is used to cool the charge air and reduce the intake air temperature after pressurization. The charge air in the intercooler can be reduced by 25 ℃ to 60 ℃. On the one hand, it can improve the density of charging, on the other hand, it can reduce the cylinder temperature of intake air and the average temperature of the whole cycle.
