Abstract

The invention belongs to the technical field of heating, and discloses a geothermal multi-energy complementary heat pump heating system and method in northern severe cold areas in winter. The geothermal multi-energy complementary heat pump heating system in northern severe cold areas in winter comprises a wind power supply module, a solar heat collection module, a central control module, a geothermal extraction module, a heat pump parameter setting module, a heating module, a heat pump fault diagnosis module, an early warning notification module, a heat pump dust removal module, a heating module, a temperature monitoring module, a data storage module and a display module. The heat pump fault diagnosis module needs not to perform analysis and calculation to determine fault detection resultsaccording to characteristic spectra every time, and fault detection efficiency of a heat pump is high. Meanwhile, whether heat is accumulated in a heat pump heat exchanger is judged by the heat pumpdust removal module according to operating parameters of the heat pump, so that dust removal operation is triggered, operating frequencies of a fan during dust removal operation is corrected, the dustremoval effect is guaranteed, and heat exchange efficiency of the heat pump is improved.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a geothermal multi-energy complementary heat pump heating system and method in winter in northern severe cold regions. Background technique [0002] In the current situation of tightening energy supply and increasing environmental protection requirements, people are constantly looking for new energy sources that are both energy-saving and environmentally friendly. Heat pumps are one type of new energy sources. Because the heat pump can realize the function of transferring low-temperature heat energy to high-temperature heat energy, it can utilize a large amount of heat in natural resources and waste heat resources. The heat pump absorbs heat from the surrounding environment and transfers it to the heated object (higher temperature object). Its principle is the same as that of the refrigerator, and they all work according to the reverse cycle of the heat engine, but th...
