As the most comfortable heating method, underfloor heating is installed in homes every year during the peak decoration season.
For underfloor heating, many people are familiar with wall mounted boilers and pipelines, but know very little about it. It is the underfloor heating mixed water center
When it comes to mixed water centers, the first thing to know is what a mixed water center is? What is its function?
What is a mixed water center
The mixed water center is a water temperature control system composed of a circulating water pump, an electric regulating valve, a ball valve with a temperature gauge, a controller, a temperature sensor, a filter valve, and a water collector device.
What is the function of a mixed water center
The mixing center is actually a water temperature mixing device, a device that converts hot water with high temperature difference and small flow rate into circulating water with low temperature difference and large flow rate.
In a heating system where both underfloor heating and radiators coexist, the water temperature in the main supply pipe is mostly above 80 ℃ -90 ℃. In order to ensure the required water temperature below 60 ℃ for the underfloor heating system, it is necessary to cool down the high-temperature water. The underfloor heating mixed water center system can convert high-temperature centralized heating hot water into a suitable underfloor heating water temperature between 20~60 ℃ and maintain a certain temperature difference between supply and return water.
The working principle of the mixed water center
After entering the underfloor heating system, the high-temperature heating water is mixed with the lower temperature underfloor heating return water cooled by the underfloor heating coil in the mixing component. After mixing water at a suitable temperature, it enters the water separator through a booster pump and is then cooled and heated through a floor heating coil. The booster pump is used to provide power for the mixed water.
Characteristics of underfloor heating mixed water device
1. Adopting a speed controlled shielded silent circulation pump and a silent automatic valve, it has a long service life and does not disturb the public.
2. The temperature control switch can accurately, sensitively, and reliably control the automatic constant temperature continuous mixed water supply of the system. When the water source supply is interrupted or the water source temperature is lower than the designed water supply temperature, the pump will automatically shut down.
3. Continuous constant temperature water supply can reduce the deposition of impurities and gas accumulation in the water inside the coil, eliminate the hidden dangers of gas resistance and blockage, and extend the service life of underfloor heating.
4. Due to the dual protection functions of automatic start stop and overheating, this device provides certain conditions for safe operation under unmanned management conditions.
5. Economically energy-saving, saving heat exchange stations, internal circulation saving energy, utilizing water temperature changes for intermittent work, reducing operating costs
The importance of stable water temperature in the underfloor heating mixing device is reflected in the following aspects:
1. Use mixed water cooling to supply underfloor heating, avoiding excessive water temperature affecting the service life of pipes and discoloration of wooden floors. Slowly increasing the water temperature in a controlled manner can avoid deformation, warping, and cracking caused by rapid heating of wooden floors.
By controlling the water temperature, the heat dissipation of underfloor heating can be effectively controlled, providing a more comfortable, energy-saving, and healthy thermal environment experience.
3. Fluctuations in water temperature can cause thermal expansion, contraction, and creep of pipes and fittings, reduce the service life of underfloor heating pipes, and increase the possibility of leakage and detachment of water collector connectors and fittings.
Of course, not every household needs to install a mixed water center. Only households with a heating area of over 80 square meters or a combination of underfloor heating and radiators need to install a mixed water center
