Heat supply pipeline cold accumulation technology

Abstract

The invention discloses a heat supply pipeline cold storage technology. The technology comprises a heat supply pipeline, a central control unit, a refrigerating unit, a heating unit, a cold communication pipeline, a hot communication pipeline, a sealing reversing valve, a reheating unit, an auxiliary cold storage unit, a comparison unit, a temperature log recording unit, a temperature measuring unit, an alarm unit, a heat preservation unit, a threshold value setting unit and a low-price electricity timing unit. The heat supply pipeline, the central control unit, the refrigerating unit, the reheating unit, the auxiliary cold storage unit, the comparison unit, the temperature log recording unit, the temperature measuring unit, the alarm unit, the heat preservation unit, the threshold value setting unit and the low-price electricity timing unit are arranged and used in cooperation, the problems that an existing heat supply pipeline cold storage technology usually does not have the real-time temperature measurement function in the heat supply and cold supply process and does not carry out feedback alarm after abnormality is detected, pretreatment cannot be carried out usually according to temperature changes in the daily use process, and certain inconvenience may be brought to use of a user are solved.

Description

technical field [0001] The invention relates to the technical field of district heating and cooling, in particular to a technology for cold storage of heating pipes. Background technique [0002] District heating and cooling is a way of heating and cooling buildings in a certain area. One or more energy stations provide heat and cold sources. The energy supply station is equipped with refrigerating machines, boilers, waste heat utilization equipment and conveying equipment of combined heat and power plants. The hot water, cold water, steam and other heating media provided by the energy supply station are transported to users in the area through the regional pipe network. It has the advantages of reducing pollution, improving city appearance, balancing user loads, facilitating energy management, improving energy utilization, reducing energy costs, and saving expenses. [0003] In the process of district heating and cooling, it is often necessary to involve the technology o...
