Description
Technical Field
The invention relates to a water quality stabilizing device and method for an efficient radiation air-conditioning system.
Background
In newly-built and modified residential buildings, radiation air-conditioning systems begin to be widely popularized and applied due to the advantages of no air blowing sense, uniform temperature field, high comfort and the like, and particularly, capillary radiation systems are increasingly applied due to the advantages of strong radiation heat exchange capacity, floor height saving and the like. On the other hand, the capillary system is easy to block due to small pipe diameter, so that the radiation air-conditioning system cannot normally operate, and the capillary system is difficult to clean after being blocked, so that the problem of blockage prevention of the capillary network is extremely important.
The reason for this is that the blockage of the capillary network mainly consists of two main reasons, namely scaling and the growth of microorganisms attached to the surface of the scale to form dirt, biological slime and the like. The temperature of water supply and return of the radiation air-conditioning water system is 16/19 ℃ in summer, 35/33 ℃ in the north and 30/28 ℃ in the south, and the water temperature is between 24 ℃ and 38 ℃ generally, so that the environment condition is very favorable for the propagation and growth of algae and bacteria. The breeding and death of the bacteria and algae are mixed with mechanical impurities in water to form slime, the slime affects heat conduction like scale if being attached to the inner surfaces of a pipeline and a heat exchanger, provides living space for anaerobic bacteria and accelerates the corrosion process of equipment by taking iron as a nutrient source. In addition, the water hardness difference of various regions is large, for example, the water hardness of northern China is high, and when a radiation air-conditioning system is used, scaling risks exist. If the radiation air-conditioning system does not perform comprehensive water quality management, the system is scaled and corroded, algae and germs propagate in a large quantity, the health of surrounding people is threatened, the system cannot operate normally, and the energy consumption of the system is high.
In order to prevent the pipe network of the radiation air-conditioning system from scaling and blocking, a method for filling softened water into the radiation air-conditioning system is proposed in the industry, but the selection of the softened water has some problems, on one hand, the softened water needs an ion exchanger, and the water production cost is high; on the other hand, softened water is only antiscale and is not anticorrosive, the corrosivity of the softened water is higher than that of tap water, the corrosion of a water collecting and distributing device (brass tube) in a radiation air-conditioning system is aggravated, and finally, a chemical agent is added for corrosion prevention. Therefore, for the chilled water system, soft water is not recommended, filtered tap water is used, an automatic dosing device or manual regular dosing is adopted as far as possible, and active pollution discharge is performed according to the situation.
