1原理制冷系统的能量调节一般由以下几种方式构成:①压缩机并联-多级控制;②变转速压缩机-变频等;③带有卸载装置的压缩机;④热气旁通。对于自身没有能量调节装置的单压缩机制冷系统,使用热气旁通来进行系统的能量调节是非常经济的。热气旁通阀是一种利用制冷剂压力和弹簧力的
1 Principle Cooling system energy regulation generally consists of the following ways: ① compressor in parallel - multi-level control; ② variable speed compressor - inverter; ③ with unloading device compressor; ④ hot gas bypass. For single-compressor refrigeration systems that do not have their own energy-conditioning devices, the use of hot gas bypass for system energy regulation is very economical. Hot gas bypass valve is a use of refrigerant pressure and spring force
