The expansion water tank is an important part of the HVAC system. Its role is to contain the amount of water and shrinkage in water in the system, and it is also used as a system of water supply.Generally, the expansion water tank is located at the highest point of the system, and it is usually connected to the backwater pipe near the water pump (central air -conditioned frozen water circulating water pump).
Swolling water tank manufacturer

Various imported valve accessories have sufficient inventory and complete specifications.best choice.
Principles of expansion water tank work
The expansion water tank is generally connected to the five pipelines and a valve, just like the central transportation hub, which plays a enhanced role in all parts, and the safety coefficient is high, relatively reliable, and can also save energy.Take the cooling system as an example. Specifically, the principle of expanding water tanks. Generally, the operation of the cooling system requires the flowing fluid to flow, and the flow of the coolant must be pumping its pressure.
Swolling water tank selection
1. Optional:-According to the resistance loss of R, Q0, T0, TK, liquid pipelines and valve parts, steps: -1.1 Determine the pressure difference at both ends of the expansion valve; determine the form of the valve;1.1.1 Determine the pressure difference at both ends of the valve: Δp = PK-ΔPi-PO (KPA) (1) -The: PK-Hyotic pressure, kPa, σΔpi — Δp1+Δp3+ΔP4 (Δp1 is for it is forThe liquid pipeline resistance loss; ΔP2 is the resistance loss of the elbow, valve parts, etc.; ΔP3 is the pressure loss of the liquid tube to increase, Δp3 = ρɡH; ΔP4 is the resistance loss of the liquid head and the capacity of the liquid liquid.); PO -evaporate pressure, kPa.
The role of expansion water tank
(1) Swelling, causing the fresh water in the system to have room for swelling after heating.(2) Moisturizing, the amount of water lost due to evaporation and leakage in the supplementary system and ensure that the freshwater pump has enough inhalation head.(3) exhaust, air in the discharge system.(4) Pharmaceuticals, chemical chemical agents to chemically treat cooling water.(5) Heating. If a heating device is set in it, heated cooling water can be heated for the heating cylinder.
