High Efficiency Stainless Steel U-Shaped Heat Exchanger from China Suppliers and Factory for Optimal Heat Transfer
Description
Capacity & Biological Pollution Risks
Approximately 20% to 25% of the water storage capacity below the centerline of the heat medium conduit is room temperature water or cold water below the specified water temperature, resulting in a lower utilization rate of the storage tank's capacity. In addition, due to the appropriate water temperature, sufficient oxygen supply, and abundant nutrition in local areas, bacteria are prone to breed, causing biological pollution of water quality.
Laminar Heating Method
The stacked heating method of U-shaped volumetric water heater can be called "laminar heating".
Main Control Parameters
Effective volume of the water heater
Heating area
Hot water flow rate
Heat exchange rate
Heat transfer coefficient K
Shell side pressure
Tube side pressure
Heat medium parameters
Frequently Asked Questions
Q1: Why is the utilization rate of the storage tank's capacity reduced?
Approximately 20% to 25% of the water storage capacity below the centerline of the heat medium conduit remains as room temperature or cold water below the specified temperature, which lowers the overall utilization rate.
Q2: What causes bacterial breeding in volumetric water heaters?
Bacteria breed due to appropriate water temperatures, sufficient oxygen supply, and abundant nutrition in local areas of the water heater, which can lead to biological pollution of water quality.
Q3: What is "laminar heating"?
"Laminar heating" is the term used to describe the stacked heating method employed by U-shaped volumetric water heaters.
Q4: What are the primary control parameters for U-shaped volumetric water heaters?
The main control parameters include the effective volume of the water heater, heating area, hot water flow rate, heat exchange rate, heat transfer coefficient K, shell side pressure, tube side pressure, and heat medium parameters.
Q5: Which pressures need to be monitored in these water heaters?
Both the shell side pressure and the tube side pressure are critical control parameters that must be monitored.
Q6: What water quality issues can occur in these heating systems?
Biological pollution of water quality can occur if bacteria are allowed to breed in local areas that have suitable temperatures, oxygen, and nutrients.
