Instead of using a mechanicalcompressor running on electricity, thermal coolers are powered with hot water.
这种冷却机不是用靠电运行的机械压缩机,而是用热水运行的。

This has the advantage of eliminating two wasteful steps: the conversion of the mechanical power of a windmill into electricity and its subsequent reconversion into mechanical power in a compressor.
这可消除两处能耗,即在风力的机械能转化为电能时,以及随后压缩机中的电能转化为机械能时。

This process involves a compressor and with it associated thermal, mechanical and pumping losses, which affect fuel consumption.
