As the requirement of energy - saving and indoor environment gets higher and higher , variable flow technology are widely used in heating and air conditioning systems , namely by changing power or resistance to adjust the flow of the system �� subcircuit and terminal equipment so as to match usually mutative dynamic heat ( cold ) load variation
