Abstract
The invention provides a refrigerating method by utilizing waste heat and a refrigerating system. The method is characterized in that after being compressed by a compressor (1), high-temperature high-pressure refrigerant gas enters a condenser (2) to be cooled into liquid in the condenser (2), then the normal-temperature high-pressure liquid enters a liquid storage device (3) to exchange energy with heat (the heat can be sourced from the local system and also can be sourced from other sources) inside a heat exchanger (6) in the liquid storage device (3) so as to be continuously cooled, then the liquid is decompressed by a throttling valve (4) and enters an evaporator (5) to be evaporated, the refrigerant is sucked by the compressor after passing through the heat exchanger (6), and thus the refrigerant is circulated in the refrigerating system.
