Problems solved by technology

[0004] Ground source heat pump is recognized as a high-efficiency, energy-saving and environmentally friendly new energy cooling and heating technology for buildings. Laying underground heat exchange pipes requires high initial investment, and problems such as too large area occupied by buried pipes or insufficient buried pipe area will also be faced
Especially in northern heating-only or heating-based projects, the traditional buried pipe...

Abstract

The invention discloses a heat pump system and method for utilizing waste heat of urban household waste landfill in adjusting and controlling modes. The heat pump system comprises an end user collateral circulation loop, a landfill upper layer horizontal buried pipe circulation loop, a ground source side vertical buried pipe circulation loop, a landfill middle and lower layer horizontal buried pipe circulation loop and a concurrent heating circulation loop. The heat pump system and method adopt technological means to adjust and control decomposition of organic matter in household waste and have very positive significance for recycling and using the waste heat from decomposition of the organic matter and available resources such as methane, alleviating or solving the problem of winter efficiency attenuation of traditional ground source heat pumps, accelerating the settlement stability of a landfill, and promoting reclamation and reuse of land in field areas.

Description

technical field [0001] The invention belongs to the field of heat supply equipment, and in particular relates to a heat pump system and method for regulating and utilizing waste heat from landfilling municipal solid waste. Background technique [0002] In recent years, with the continuous expansion of my country's urbanization process, the improvement of people's living standards and the increase of urban population, the amount of urban domestic waste is also increasing year by year. Judging from the current economic status and future development trend of our country, landfill is still the most important method for disposing of municipal solid waste in our country. [0003] Stabilization of municipal solid waste landfills is a very long process, generally going through aerobic stage, anaerobic stage, acid production stage, methane production stage and stabilization stage, and this process generally lasts for more than ten or even tens of years Years, it will occupy a large ...
