Description

Technical field: [0001] The invention relates to an improvement of a device for providing energy by using urban sewage. Background technique: [0002] Urban sewage is a rare cold and heat source for heat pump heating and air conditioning, especially in cold northern regions. Using heat pump air-conditioning equipment to extract heat from urban sewage in winter and release heat in summer to achieve heat and cold recovery, not only utilizes renewable energy, but also avoids the inevitable pollution of the environment by using fossil fuels as heat sources. The biggest technical difficulty in using urban sewage as a cold and heat source for heat pump air-conditioning units is how to prevent sewage from polluting and clogging pipelines and heat exchange equipment. Sewage treatment for this is not feasible, because the minimum cost of sewage treatment is also higher than the value of extracting heat or cold from sewage. It is also not a good idea to take sewage into the system f...
