Heat recycling system adopting centralized heat supply pipe network to transfer refrigeration waste heat in summer

Abstract

The invention provides a heat recycling system adopting a centralized heat supply pipe network to transfer refrigeration waste heat in summer. The system comprises an urban centralized heat supply underground primary network water supply main pipeline and water return main pipeline, and a refrigeration unit of cold air users; the innovation made is that a central refrigeration waste heat recycle bin and / or a household refrigeration waste heat recycle bin, a consumption hot water heat exchange station, and a primary network branch pipeline connected with the waste heat recycle bin are arrangedalong a heat supply primary network. The system has the positive effects that the centralized heat supply primary network which is in the dormant state in the summer is recovered, and is used for conveying the collected heat extraction caused by refrigerating and converting the collected heat extraction into the required hot water in the area, so that all-weather energy storage and long-distance heat conveying can be achieved, and the requirement of the hot water users dispersing along the primary network is met. The utilization efficiency of the secondary energy is improved, and the single central refrigeration and the household refrigeration are changed into the large-scale regional cold-hot combined supply comprehensive utilization. The comprehensive utilization level on the refrigeration waste heat of the household along the primary network is improved, and the energy consumption for producing the hot water is reduced, and the system relieves the urban heat island effect caused byrefrigeration.

Description

technical field [0001] The invention belongs to the field of heating, and relates to a heat recovery and utilization system for transferring waste heat of refrigeration in summer through a centralized heating pipe network. Background technique [0002] At present, institutions, commercial buildings and residential buildings generally use air conditioners for refrigeration in summer. A large number of cooling towers and household air conditioners continue to spread waste heat in the city, exacerbating the urban heat island effect and the formation of air pollution; in addition, some residents and businesses (such as bathing places) still use hot water in summer. These hot water users all obtain hot water through consumption of electricity, gas, and coal. Form the contradictory phenomenon of the coexistence of heat abandonment and energy consumption and heat acquisition in the same area. In terms of quantity, it is more than enough to collect building cooling waste heat and ...

Problems solved by technology

This kills two birds with one stone, because there is no technical means and equipment for centralized storage of cooling waste heat and long-distance transportation, resulting in the phenomenon of cooling to the atmosphere in summer in cities and hot water users consuming electricity and fuel.
