Abstract
The utility model discloses a refrigeration system, which comprises a compressor assembly, a condenser, an evaporator and a refrigeration circulation loop. The compressor assembly is formed by parallelly connecting two compressors which work in an alternative and back-up mode and is used for compressing low-temperature low-pressure gaseous refrigerants into high-temperature high-pressure gaseous refrigerants. The condenser is used for condensing the high-temperature high-pressure gaseous refrigerants compressed by the compressor into constant-temperature high-pressure liquid-state refrigerants through heat exchange with cooling media. The evaporator is used for enabling the low-temperature low-pressure liquid-state refrigerants after passing through a throttle valve to exchange heat with cooling media and transforming the low-temperature low-pressure liquid-state refrigerants into gaseous refrigerants to achieve refrigeration. The refrigeration circulation loop is formed by the compressor assembly, the condenser, the throttle valve and the evaporator. By arranging two parallelly connected compressors to achieve alternative working and mutual backup, whole service life of devices is ensured, and the reliability of the whole system is ensured simultaneously.
