AUTOMATIC BALANCE VALVE ASSEMBLY, METHOD FOR CONTROLLING WATER FLOW AND COMPUTER-READABLE MEDIUM

摘要

A self-adjusting balance valve controller (401) controls water flow through a hydronic emitter (101) in a heating and/or cooling temperature control system. The valve controller (401) obtains a measured temperature differential between an inlet (102) and an outlet (103) of the hydronic emitter and determines a displacement of a coupling pin (303) from the measured temperature differential. The valve controller (401) then instructs a driving mechanism (304) to move, through a coupling mechanism (306), the coupling pin (303) to adjust a valve (106) that results in a desired water flow through the hydronic emitter (101). The valve controller (401) may maintain a stable temperature differential at a desired differential value, which may be obtained through a user interface (404) or from a memory device (405). Moreover, the desired differential value may vary with different times of operation or temperature control situations.
