Description

(1) Technical field

[0001] The invention relates to a heating device, in particular to a cascade ultra-high temperature water source heat pump device that converts low-grade heat energy of groundwater into high-grade heat energy that can be directly used. (2) Technical background

[0002] At present, in our country, the heating and heating of buildings, except for part of the central heating for thermal power plants, is almost all for the heating of scattered fuel boiler houses. These heating devices rely on the direct combustion of solid fuel coal or oil to obtain heat, which is not only inefficient, It causes energy waste, and the carbon dioxide gas and smoke produced by combustion cause serious pollution to the environment. With the global energy crisis and the increasing awareness of energy conservation and environmental protection, exploring energy-saving and environmentally-friendly heating devices has become a top priority.

[0003] The emergence and development of water s...
