Description

Technical Field

[0001] The utility model relates to the technical field of heating systems, in particular to a thermal inlet filtering water return device. Background Art

[0002] Heating refers to providing heat to a building or a certain area to maintain a suitable temperature environment. There are mainly the following ways to provide heating: Central heating: hot water or steam is delivered to each user through a large heat source (such as a thermal power plant, a large boiler room, etc.), which has economies of scale and high energy efficiency. Regional boiler room heating: a boiler room is set up in a specific area to provide heating for surrounding buildings. Household heating: users install heating equipment by themselves, such as gas wall-mounted boilers, electric heating, etc. Geothermal heating: heating using underground heat energy. Heating is essential for people's living and working environment. It ensures a comfortable indoor temperature in cold seasons. It is also widely used in industrial production processes to meet process requirements. The continuous development and improvement of the heating system aims to improve energy efficiency, reduce environmental pollution, and enhance user experience.

[0003] A heating system is a system used to provide a warm and comfortable environment for a building. It usually consists of the following main parts: Heat source: such as boiler room, thermal power plant, etc., responsible for generating heat. Heat medium delivery pipeline: used to deliver heat to various areas. Heat dissipation equipment: common ones include radiators, floor heating coils, etc., which dissipate the heat carried by the heat medium to the indoor space. Control devices: including valves, temperature controllers, etc., used to adjust the distribution of heat and the temperature. The working principle of the heating system is that the heat generated by the heat source is transmitted along the pipeline through the heat medium (such as water, steam or hot water, etc.) to the heat dissipation equipment in each room. The heat dissipation equipment exchanges heat with the indoor air, thereby raising the indoor temperature. The heating system can be divided into water heating system, steam heating system, etc. according to the different heat media; according to the location of the heat source, it can be divided into central heating system and household heating system, etc.
