  • Page 32 4. System Design 4-1-2. Notes on pipe Corrosion Water treatment and water quality control Poor-quality circulating water can cause the water-side heat exchanger to scale up or corrode, reducing heat exchange performance. Properly control the quality of the circulating water. Removing foreign objects and impurities in the pipes During installation, keep foreign objects, such as welding and sealant fragments and rust, out of the pipes.
  • Page 33 4. System Design 4-1-3. Pipe gradient and air venting valve (Outlet hot water pipe) During the hot water storage operation, the air dissolved in the water is discharged in the form of bubbling from the outlet hot water pipe to quickly raise low-temperature water to the required temperature. When the air accumulates in the pipe, the resistance of the water circuit will increase and the flow rate will extremely decrease.

    4. System Design 4-2. QAHV Secondary side control 4-2-1. General description and purpose of secondary side control Secondary side control is a control method to raise the hot water temperature in the tank by using another heat exchanger added between the tank and the existing heat exchanger. By incorporating the secondary side control to the QAHV, the need to assemble a pump control on-site is eliminated, and the system construction in cases where water exceeding the QAHV water quality standard is used is now easier.
