What principle of floor heating is plumbing, electric warming, and warming?

December 17, 2020

With the improvement of living standards, more and more owners are beginning to pursue healthy, comfortable and energy-saving home life concepts. The rise of floor heating has made people have one more choice besides air conditioning and heating. Today Xiao Bian wants to take everyone to learn more about the principle of floor heating and see how they work.

First, what is the principle of warmth

Plumbing - A heating method using hot water as the heating medium and heating the ground through special pipes;

a) underground hot springs; b) independent gas; c) central heating.

Electric heating - converting electric energy into heat medium, and controlling the temperature of the laying area through a temperature control meter;

a) heating cable; b) carbon crystal electric film; c) carbon crystal electric hot plate.

Light warm - A type of heat that converts light energy into a heat medium and can store and supply heat energy.

a) solar heating; b) solar + gas heating; c) solar + electric heating; d) solar + gas + electric heating.

  

1, low-temperature hot water radiant floor heating

Working principle: Using hot water whose temperature is not higher than 60°C as the heating medium, circulating in the heating pipe buried in the filling layer below the ground, heating the entire floor, and heating the room through the ground in a heat transfer manner of radiation and convection. A heating method.

The temperature of water supply for civil buildings should be 35-50°C, should not exceed 60°C, and the temperature difference between supply and return water should be less than or equal to 10°C.

  

Water heating: Mainly consists of boilers, manifolds, surface water pipes, radiators, thermostats, and connecting parts and auxiliary materials.

2, heating cable ground radiation heating

A heat-generating cable with an outer working temperature limit of 65°C is buried in the floor, the floor is heated with a heat-generating cable, and the room temperature or floor temperature is controlled with a thermostat to achieve radiant floor heating.

3, low temperature radiation electric film heating

Electric heating film: A translucent polyester film that can be heated after being energized, made of conductive special ink, metal current-carrying strips, and heated between two layers of insulating PET polyester film.

Electric film heating system: The electric heating film is equipped with a connection card, a trunk line, a three-core T-type cable, a built-in protective grounding system, and an external heating device sealed with an insulating material.

Electrothermal film heating system of the main equipment: electric film, thermostat.

(1) Radiant floor heating refers to the fact that through a heating tube buried in the floor, the heated surface emits far-infrared rays of 8–13 μm, which stimulates “hot spot” sensors that are 2 mm deeper into human skin, making people feel warmer. .

(2) Radiative heat transfer does not rely on the contact of objects for heat transfer. Instead, as the sunlight radiates through the atmosphere to the ground, the emitter converts the internal energy in the body into radiation energy. When radiant energy is absorbed by another object, it is converted into the internal energy of the object.

(3) The specific radiation method uses electricity as energy or hot water to flow through the plastic pipe, and the heat energy is conducted to the ground. The ground sends heat to the room in the form of radiation, which is absorbed by the human body and converted into heat energy to feel warm and further improve. The role of room temperature.

  

  Summary: The relevant content of the principle of floor heating is introduced here and I hope to help you. If you are still unsure about it, you can pay attention to the website decoration information channel, where there is more you want to know.

    Surface Grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.

    Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.
The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, and a reciprocating or rotary table. The chuck holds the material in place while it is being worked on. It can do this one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-ferromagnetic and nonmetallic pieces are held in place by vacuum or mechanical means. A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available.
    Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on.
Typical workpiece materials include cast iron and mild steel. These two materials don't tend to clog the grinding wheel while being processed. Other materials are aluminum, stainless steel, brass and some plastics. When grinding at high temperatures, the material tends to become weakened and is more inclined to corrode. This can also result in a loss of magnetism in materials where this is applicable.
