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.
