Volumetric heat exchanger Volumetric heat exchanger Semi-volume heat exchanger
A volumetric heat exchanger, which consists of a body, a steam coil assembly in the body, a steam inlet and outlet, a cold water inlet and a heat exchanger. The water outlet composition is characterized in that a layer of high-temperature melted anti-corrosion alloy layer is sprayed on the inner surface of the device body. Volumetric heat exchangers are made by enlarging the volume of ordinary floating coil heat exchangers. Mainly used in hot water supply systems. Generally, an automatic temperature control device should be installed at the outlet to ensure the appropriate water supply temperature for bathing water or sanitary hot water. In addition to having all the advantages of ordinary floating coils, it can also store a certain amount of hot water to ensure timely supply of hot water.
The volumetric heat exchanger is suitable for hot water supply systems in general industrial and civil buildings. It has the following characteristics
High thermal coefficient. The heat transfer element of this equipment is a purple multi-head spiral groove with convex inner and outer surfaces. During the heat transfer process of copper tubes, due to its high flow rate (/low operating resistance), a strong spiral state is formed inside and outside the heat exchange tube, which causes the tube wall to vibrate, and the heat transfer coefficient increases greatly while the tube length remains unchanged. The heat exchange area is increased, thereby effectively improving the heat exchange capacity.
Easy to fouling Since the heat exchange tube is processed by a special process, strong swirling fluid is formed inside and outside the tube during the heat transfer process, which is harmful to The inner and outer walls of the heat exchange tube form a strong scouring effect. At the same time, the heat exchange tube itself has the ability to expand with heat and contract with cold. Therefore, scale is difficult to stick to the inner and outer walls of the heat exchange tube, making it difficult to scale.
Easy to leak because the heat exchange tube itself has the ability to expand with heat and contract with cold. The heat exchange stress is reduced accordingly during the heat transfer process, so each expansion tube is less likely to leak.
Rapid heating Due to the special structure of this product, the heat generated The water quickly reaches the hot water outlet at the top of the tank, and hot water can be supplied to the outside without heating most of the cold water.
Cold water area, high volume utilization This product always heats the cold water at the bottom of the tank, and the water consumption is low At the rated water supply capacity, gradually heat all the cold water in the tank. At this time, there is no cold water zone to maintain the maximum reserve of hot water. When the water consumption is greater than the rated water supply capacity, the hot water stored in the tank and the hot water heated immediately At the same time, it can be supplied to the outside to pass the peak water consumption. When the heating medium is stopped due to accidents or other reasons, the stored hot water can be supplied to the maximum extent.
When steam is used as the heating medium, this product can reduce the humidity of the condensed water. in.
