Background

The water-ground heating or water machine air conditioner is the most extensive heating mode in the heating and ventilation industry, and has centralized heating and distributed heating, and particularly the water-ground heating is the most common in cold regions.

Generally, circulating water in a water-ground heating system is dirty and has a lot of impurities, so that the control failure of a water collector is easily caused, the scaling of a ground heating pipeline is caused to greatly reduce the heat exchange efficiency, correspondingly, the energy consumption is increased, the heating cost is increased, and the water rises, so that great waste is caused to energy.

In view of the above situation, in traditional water floor heating, a Y-shaped filter is often installed in front of a water collecting and distributing device and used for filtering impurities in water, but the Y-shaped filter is small in filtering precision and limited in filtering capacity, cannot regularly and fully automatically discharge sewage and remove dirt, and brings inconvenience to users.

Traditional irrigated and heated floor lacks the protection of leaking, and although irrigated and heated floor has a great deal of advantage, irrigated and heated floor is afraid of leaking most, in case leak, will cause huge loss of property for the user.

The traditional water floor heating system does not have a scale inhibition function usually, scaling of a pipeline valve is easily caused, and energy consumption is increased.

The traditional water floor heating system does not have a water hammer prevention function usually, the water hammer is harmful greatly, and the floor heating pipe can burst seriously or the vibration of various parts is aggravated to cause noise.
