Application of heat pump to decontaminate British net element in heat pump

In nature, water always flows from high to low, and the heat is always transferred from high temperature to low temperature. But people can use water pumps to raise water from low to high, in order to achieve the flow of water from low to high. So, is there a kind of "pump" that can transfer heat from low temperature to high temperature? As far as this issue was concerned, as early as the early 19th century, people were keenly interested in the industrial revolution and in the fifties, the concept of a heat pump was first proposed. Heat pump is essentially a heat-lifting device, the role of the heat pump is to draw heat from the surrounding environment and deliver it to the heated object (the object of higher temperature), its working principle and the same refrigerator, are in accordance with the inverse Carnot cycle work, the only difference is the operating temperature range.

In the 1930s, with the development of Freon refrigerators, heat pumps developed rapidly. The global energy crisis of 1973 further promoted the worldwide development of heat pumps. Heat pump worldwide large-scale commercial applications is the last 20 years, China's heat pump industry has started in recent years, but also the momentum of development is promising. Heat pump heat source mainly air, water and soil sources and other forms. At present, our country uses more water source heat pump, and using air source heat pump to make domestic hot water has also gradually risen in China in recent years. In addition, due to its unique advantages, ground source heat pump has drawn more and more attention in recent years.

Due to the working mechanism of the heat pump, the heat exchange medium (water or antifreeze containing water as the main component) eventually exchanges heat with the actual water, so that the application of the heat pump faces a problem - scale. If the ground-source heat pump uses an open system, that is, the water pump is used to directly extract groundwater and exchange heat with the refrigerant and recharge or discharge at a suitable location. Groundwater contains more minerals, higher hardness, the scale problem is particularly prominent. To CaCO3, for example, the thermal conductivity of only 0.6-2.0 kcal / m2 · h · ℃, while the thermal conductivity of copper up to 260-340 kcal / m2 · h · ℃, from which we can see that as long as the exchange A thin layer of heat on the surface of the scale, resulting in heat loss is quite large. In fact, all heat pump manufacturers have always wanted to find a way to solve this application problem thoroughly.

At present, the domestic scale removal methods are mainly divided into: chemical methods and physical methods. Chemical methods Currently there are chemical agents, demineralized water and reverse osmosis and other methods, the technology has been basically forming. However, due to the many disadvantages of chemical methods, such as corrosion of equipment, the need to stop production, professionals need to operate, and expensive, need to follow-up investment. The heat pump itself belongs to a new type of energy-saving products, the use of chemical descaling will be subject to some limitations. Physical methods, which have many years of successful experience in foreign countries. In China, over the years, it has been the market for some early products. Due to limited application effects of these products, many users have avoided them and, to a certain extent, influenced people's perception of it. Until recent years, the emergence of a new coil-wound electronic descaling device has re-attracted people's attention.

British Water Treatment Company is one of the world leaders in the field of physical scale removal of scale. The company since the eighties of last century engaged in physical law to scavenge scale research, in the early nineties to develop the first generation of coil-type electronic induction water processor. In the subsequent application of the technology continues to improve, and completed in 2000 to upgrade, began the introduction of the latest generation of net yuan multi-function electronic sensor water processor. The water processor has superior descaling performance and has many advantages:

Unique digital frequency conversion technology, higher stability, stronger anti-interference ability;

Anti-scaling: prevent equipment and piping (boilers, heat exchangers, cooling towers, etc.) scaling;

Descaling: the gradual removal of equipment and pipe scale already exists;

Winding the coil outside the pipe without cutting the pipe or drilling holes in the equipment;

Not limited by the flow rate and hardness of water, the effective distance up to 100Km;

No contact with the process medium, maintenance-free;

For metal and non-metallic pipe;

Output power less than 50W, low operating costs;

With remote monitoring capabilities;

At the same time with sterilization, activation of water quality, rust and corrosion inhibition;

Eliminate the removal of detergents, corrosion inhibitors, save the cost of manual cleaning, reduce downtime;

Improve heat transfer efficiency, save energy by 30% -50%.

Kaili City, Guizhou Province Hongqi Hotel, located in Kaili City, Guizhou Province, the crossroads of the most prosperous city commercial center. There are eighty-five standard rooms, more than 80% accommodation rate, daily water supply 25 tons. Is used in Shandong, a heat pump manufacturers to provide air-source heat pump to produce hot water. Because of the local karst topography, high calcium carbonate water content, is a heavy calcium, can easily cause any kind of scaling of hot water equipment. The air-source heat pump water quality has a special high demand. Therefore, the hotel has purchased three different manufacturers of domestic well-known brands of electronic descaling instrument, but did not achieve the effect of scale and anti-scaling. Cause the water temperature is too low, insufficient water supply. Hotel had to spend thousands of dollars to build a container for storing pickling syrup, and on average every 25 days have to buy pickled syrup worth 200 yuan, and each pickling process must be shut down, can not supply and meet the customer Hot water. Therefore, it has also affected the hotel's source of tourists.

Since the installation of the British net yuan multi-function electronic sensor water processor, it has not been pickling three months. During this period, a total of 3 times to open the heat pump to see the wall without any scale. Heat pump heater inside clean as new. Water temperature and water supply have reached the technical requirements of heat pump design.

magical! Amazing Impressed! - This is Hong Qi (Hotel) general manager of British net multi-functional electronic sensor water processor emotion. Net element also has sterilization, activation of water quality, can promote biological growth and promote metabolism. I believe soon, the hotel will feel the net worth of services. From Guizhou Hongqi Hotel application, we can see that, both from a technical point of view, or economic point of view, the United Kingdom net yuan multi-function electronic sensor water processor fully meet the requirements of users; the same can be seen, not just the air Source heat pump, also includes water source heat pump, ground source heat pump, so that based on the principle of heat exchangers, and even all water-based scaling problems, net yuan can give users a satisfactory answer.
