Hello, I can only send a total of about a book, not so many words. <>

What is the pipe spacing.

I'll help find some.

Hello There are two kinds of 16 pipe diameter and 20 pipe diameter. The spacing of toilet pipes is between 10cm-12cm. The spacing between the bedrooms and living rooms is between 20cm-25cm.

The heat load is large, and the coil should be encrypted; The heat load is small and the tube spacing is large. In order to reduce air convection and exert the effect of floor heating. The national standard stipulates that the minimum spacing between floor heating pipes is 100mm, and the maximum is not more than 300mm; 25cm or 20cm for home use; 25-30cm for public areas.

The standard for the spacing of floor heating pipes is 200mm; The standard spacing between floor heating pipes in the bathroom is 150mm, and the spacing of floor heating pipes in the basement or storage room is 300mm.

Legal analysis: "Technical Regulations for Floor Radiant Heating" This is the only specification for floor heating in our country at present, which clarifies some key points and design and construction specifications for electric heating (heating cable floor heating system) and water heating (low temperature hot water floor heating system).

The national technical regulations for radiant heating stipulate that the floor heating is:

Low-temperature hot water ground radiant heating is what we often call water floor heating: it takes no more than 60 low-temperature hot water as the heat medium, heats the floor through the heating pipe in the buried floor, and evenly radiates heat to the room, which is a part of the microclimate of the room can be heated, and the low-temperature heating cable ground radiant heating is also commonly known as electric floor heating: electricity is used as the energy source, and the heating cable is the heating element, the electric energy is converted into heat energy, and the internal surface of the building is used as the heat dissipation surface, and the surrounding air is heated by convection heat exchangeIt also radiates heat transfer to the surrounding maintenance structures to ensure that the room temperature of the building meets the comfort requirements of the heating system.

This regulation is applicable to the design, construction and acceptance of ground radiant heating projects with hot water as the heat medium or heating cable as the heating element for new industrial and civil buildings.

The Indoor Air Quality Standard (GB T 18883 2002) stipulates that the indoor temperature for heating in winter is between 16 degrees Celsius and 24 degrees Celsius.

A new type of floor heating - carbon crystal floor heating 23 degrees ecological floor heating has been recognized by the professional department as carbon crystal floor heating, and the carbon crystal electric heating plate is a heating element made of carbon crystal particles after special treatment after carbon fiber modification, and the carbon crystal particles are synthesized with special polymer resin materials.

There are national standards for floor heating, and the implementation standard is the "Indoor Air Quality Standard" (standard number: GB T 18883 2002), which stipulates that the indoor temperature of winter heating is 16 degrees Celsius to 24 degrees Celsius.

Indoor Air Quality Standards specify indoor air quality parameters and test methods. This standard is applicable to residential and office buildings, and other indoor environments can be implemented with reference to this standard.

The Indoor Air Quality Standard (GB T 18883 2002) stipulates that the indoor temperature for heating in winter is between 16 degrees Celsius and 24 degrees Celsius.

For the time being, there is no unified national standard, but the national standard for floor heating construction "Ground Radiant Heating Technical Regulations" has begun to be revised and ordered, if the floor heating pipe is too thin, it will cause uneven heat dissipation, and if it is too dense, it will cause invisible waste, so it is necessary to choose a regular floor heating construction unit, which is more professional.

Ask a practical question, what is the length of a geothermal pipe for laying a node.

Answer: The length of each road is as close as possible, in the middle of 80---120 meters, the length is close to the temperature, if the length gap is large, the temperature gap will be large, and the valve needs to be adjusted to solve, if the length is more than 120 meters, the cycle is not good, it is not easy to heat. Generally, it is better to keep the branches at 100 meters.

Ask what is the length per square meter.

There is no experience point.

AnswerFirst of all, the floor heating should not be less than 50 meters per road, it is recommended that it is between 90 meters, not more than 120 meters, and it cannot exceed 15 square meters in each pipe. That's because floor heating uses the entire ground as a radiator, passing through the radiant layer of the floor heat medium, evenly heating the entire ground. The ground itself is used to store heat and radiate heat upwards for conduction, and then achieve the purpose of heating.

Hope it helps, dear

Asked whether the geothermal pipes can be heated in the middle, the developer reserved a few meters of the geothermal pipes of the caisson toilet, but there is no vent, what should I do?

Hope it helps, dear

For the time being, there has not been a unified national standard, but the national standard for floor heating construction "Ground Radiant Heating Technical Regulations" has begun to be revised, if the floor heating pipe is too thin, it will cause uneven heat dissipation, if it is too dense and will cause invisible waste, so it is necessary to choose a regular floor heating construction unit, which is more professional. Hope to adopt!

The pipe spacing and diameter are related to the heat storage of your room, and they are generally 15cm or 20cm

Generally, there is a national standard, such as the bulk density of the module.

Do you want to do underfloor heating?

Not yet, it's being written.

What you want to ask is what are the requirements of the aluminum film specification for floor heating pipes? There are material requirements, specification requirements, and installation requirements.

1. Material requirements: The material of the aluminum film of the floor heating tube should meet the relevant standards, and the common materials are high-performance PE film, PET film, nano silver flat, etc. It should have the characteristics of high temperature resistance, non-toxic, moisture-proof, mildew-proof, anti-static, anti-oxidation, corrosion resistance, etc.

2. Specifications: The thickness, width and length of the aluminum film and other parameters should meet the relevant specifications and standards. Generally speaking, the thickness of the aluminum film of the floor heating pipe is above, the width is between 600mm-1500mm, and the length can be cut on demand.

3. Installation requirements: The aluminum film of the floor heating Zhiye pipe should be laid and installed in accordance with the relevant requirements. Generally, it is necessary to ensure that the aluminum film is in good contact with the ground to avoid bubbles and wrinkles, so as to ensure the smooth heat transfer and thermal effect of floor heating.

The standards and requirements of aluminum film for floor heating pipes are sometimes updated and improved with the changes in factors such as technical improvement, industry standard spine localization and market demand, so when laying and using aluminum film for floor heating pipes, it is also necessary to consult the opinions and suggestions of professionals according to the actual situation, and do a good job in standardizing construction and maintenance management.

The corresponding national standards for floor heating include JGJ142-2012 [Technical Regulations for Ground Radiant Heating and Cooling], CECS424:2016 Technical Regulations for Thin Dry Floor Heating of Prefabricated Trench Insulation Modules, etc.

The selection criteria for floor heating are: [Floor Radiant Heating Construction Atlas] 12K404.

Floor heating is divided into wet floor heating and dry floor heating two technologies, wet floor heating with insulation board concrete backfill wet construction, suitable for high entry threshold, need a long time of floor heating occasions; Dry construction of prefabricated trench insulation floor heating module for dry floor heating is suitable for intermittent heating occasions with low threshold design, high heating temperature and energy saving.
