Closed type circulation heating system capable of meeting different heating temperature requirements

Abstract

The invention discloses a closed type circulation heating system capable of meeting different heating temperature requirements. The closed type circulation heating system comprises a heat source system, an output system and a user system, wherein the heat source system is used for providing heat energy for users and recovering after-use residual heat energy, the heat source system internally comprises an energy tower, the output system is used for conveying the heat energy generated by the heat source system into all groups of heat users in a heat network and recovering the residual heat energy circulating in all the heat users back into the heat source system, the output system internally comprises an energy tower heat pump unit, and the user system is a heat user at the last end in the heat network and is composed of the plurality of heat users. The heat energy in the heat source system is conveyed by a conveying pipeline into water tanks of user terminals of the user system, the users can set required temperatures in temperature setting units, the water tanks of the users are heated by electric heating equipment, the heat energy in the water tanks reaches temperatures required by the users, different heating temperatures are provided according to demands of the users, and the circulation heating system is more user-friendly and more reasonable.

Description

technical field [0001] The invention relates to the technical field of heating systems, in particular to a closed cycle heating system for different heating temperature requirements. Background technique [0002] Heating is mainly aimed at keeping warm in northern cities. At present, the main measures taken by our country are centralized heat supply, which is to use centralized heat sources in a larger area to supply production, living and heating heat to factories and civil buildings in the area. Central heating has a history of nearly one hundred years. Because it has the advantages of saving fuel and reducing urban pollution, it is developing very fast. More than 20 countries in the world have adopted central heating. [0003] With the rapid development of the economy and the improvement of people's living standards, people's demand for domestic hot water and heating hot water is also increasing. According to statistical data, the proportion of my country's building e...

Problems solved by technology

[0005] The purpose of the present invention is to provide a closed cycle heating system that can meet the needs of different heating temperatures, so as to solve the problem that the temperature provided to each heat user by the existing central heating network in the background technology is fixed, but in Different regions and different groups of people have different temperature requirements. If a fixed temperature is used, some groups feel that the temperature is too high and will dissipate heat through windows. Some groups feel that the temperature is too low and will use additional heating equipment again. This process will cause two-way unnecessary waste of resources
