Abstract:
Provided are a superhigh temperature heat pump system and method capable of preparing boiling water not lower than 100° C., belonging to the technical field of heat pumps. The system comprises a compressor (1), primary and secondary evaporators (5, 6), an expansion mechanism (4), primary and secondary condenser/coolers (2, 3), water pumps (7, 8, 13), water tanks (9, 10), and a valve (14). The solution is based on the compressor exhaust heat enthalpy utilization minimum entropy gain principles/technology, and utilizes exhaust heat enthalpy sensible heat and latent heat in stages. The present invention has an output water temperature higher than 100° C., expands the functions of current heat pump water heaters which can only prepare hot water lower than 100° C., and can replace electric water heaters, save energy and increase energy utilization rates.
