1. What is a capillary network?
The capillary grid (4.3 * 0.8mm PPR raw material) imported from Nordic chemical industry replaces the traditional indoor unit and is installed inside the building. It is invisible. It relies on water as the cooling and heating medium for cooling and heating. It mimics the capillary structure of human body and has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, large heat exchange area, good thermal conductivity, uniform heat exchange and small hydraulic loss;
The inlet water is about 16-22 ℃ in summer, the return water is about 19 ℃, the inlet water is about 30-35 ℃ in winter, and the return water is about 33 ℃. Through circulating heating or cooling the water in the capillary grid, the heat or cooling capacity of the indoor environment is provided, and the effect of constant temperature in four seasons is achieved.
2. High comfort
Practice shows that radiation is the most comfortable heat transfer mode. However, 60% of the cooling capacity and heat of the capillary network radiant air-conditioning terminal system are conducted by radiation, so it is more comfortable than other terminal forms.
3. The quietest air conditioning system.
Compared with the traditional fan coil unit (fan coil unit has indoor moving parts such as motor and fan, which will generate about 35-45db noise), the capillary radiation air conditioning system has no indoor moving parts, and will not generate any indoor noise. It is a quieter air conditioning system.
4. There is no condensate tray and no source of bacteria.
The capillary mat is embedded in the ceiling or wall, and mainly relies on radiation heat transfer to supply cooling or heat to the building. Compared with the fan coil, there is no condensate system, and there will be no poor drainage and water dripping. There is also no phenomenon that bacteria breed in the drip tray of traditional fan coil units and affect the indoor sanitary conditions.
5. The energy saving effect is remarkable.
Generally, the water supply temperature of the capillary system is 16-22 degrees in summer and 30-35 degrees in winter. Compared with the traditional air conditioner, it has a higher water supply temperature in summer and a lower water supply temperature in winter, which can save a lot of energy.
6. Strong cold / heat storage capacity.
The temperature will not increase (summer) or decrease (winter) for a long time in the state of system shutdown or power failure.
7. Strong self-adjusting and balancing ability.
In summer, with the increase of indoor temperature and the temperature difference of radiation surface, the radiation cooling capacity is increased. In winter, with the decrease of indoor temperature and the increase of temperature difference of radiation surface, the radiation heat is increased.
8. The capillary end occupies a small building clearance and saves floor height.
Under the leveled ceiling or part of the wall surface in the air-conditioned room, first lay the capillary net and mesh cloth, and then apply two layers of 5-10mm thick putty to form the radiation surface.
9. Flexible capillary arrangement and convenient construction.
Due to the relatively light weight of the capillary tube (the weight of the net filled with water is only 370 g / m2), the arrangement is flexible, and there are many installation methods, such as ceiling plastering installation and wall plastering installation, which are convenient for construction.
10. It is especially suitable for use with air source heat pump and ground source heat pump to achieve more energy-saving effect.
11. Safe and reliable, long service life.
The capillary network is subject to strict quality control and testing in production to ensure its safety and precision. Before each product leaves the factory, it must undergo a long-term strict test of 10bar, with high reliability.
After installation, the system must be tested again with a pressure of 10bar, so that the damage can be immediately found on site and solved. After the whole system is installed, the capillary network system shall be subject to multi-level strict test again according to the working standard.
