Abstract： |
This invention relates to a multi-stage serial large temperature-difference compression thermal pump set composed of multiple stages of condensers, evaporators, a compressor and a related throttle device and connection pipelines, in which the waterway systems of the condensers of each stage and evaporators are serial to form a connected in-out system of waterway, pipelines of cold-producing medium of the adjacent condensers are serial by the throttle device, the condenser of the last stage is connected with the evaporator of the first stage by the compressor to form a channel of cold-producing medium. |
