１前言蒸汽压缩式循环和蒸汽型、直燃型吸收循环是目前应用最广的制冷循环。压缩式循环的能效比一般为２．５－４．５，其折算后的一次能源利用率大概为０．９～１．５。吸收循环直接由热驱动，其能效比一般在０．７～１．２左右。直燃型吸收循环由于高压发生器炉膛与溶液...
1 Introduction Vapor compression cycle and steam type, direct combustion absorption cycle is the most widely used refrigeration cycle. Compression cycle energy efficiency is generally 2.5-4.5, the converted primary energy utilization rate of about 0.9 to 1.5. Absorption cycle directly driven by heat, its energy efficiency is generally around 0.7 to 1.2. Direct combustion type absorption cycle due to high pressure generator hearth and solution ...
