Title:
ENERGY-SAVING REFRIGERATING UNIT AND COMPRESSION-EXPANSION MODULE
Document Type and Number:
WIPO Patent Application WO/2017/031616
Kind Code:
A1
Abstract:
A refrigerating unit comprises a compressor (10), a condenser (12), a liquid storage tank (14), an expansion mechanism (16), an evaporator (18), and a motor (22) driving the compressor (10). A working medium circulates among the compressor (10), the condenser (12), the liquid storage tank (14), the expansion mechanism (16), and the evaporator (18). The expansion mechanism (16) is a turbo expander (16). The working medium does work by expansion in the turbo expander (16). Power needed for driving the compressor (10) partially comes from expansion work absorbed by the turbo expander (16).
