Note:
1.ΔP represents the pressure drop from ØC to ØS or from ØE to ØS;
2. The selection capacity of the four-way valve for R32 systems should be ≥60%. It is not recommended to use the four-way valve in
systems with a capacity less than 60% of the nominal capacity. When used in R32 systems, it is essential to ensure the reliability of
low-pressure commutation under extreme conditions.
