Technical Field

[0001] The invention relates to the technical field of HVAC manifolds, and in particular to an integral manifold with a flow balance presetting function. Background Art

[0002] The upper and lower bars of the HVAC manifolds commonly used on the market are not on the same plane, and there is a large distance between the upper and lower bars. The water inlet and return interfaces are respectively set on the upper and lower bars, which not only takes up a large space, but also is very inconvenient to install.
