摘要:
A hydronic system controls the air temperature in a plurality of zones. The system has a plurality of heat exchangers, each one being associated with a respective zone. The mass flow rate of a working fluid through each heat exchanger is controlled to maintain the working fluid temperature drop across the heat exchanger a constant, chosen for efficient operation of the boiler or chiller which transfers heat to or from the working fluid. The flow of air in each zone through each heat exchanger is controlled by the air temperature in the zone. A respective valve associated with each heat exchanger is used to control the mass flow rate of the working fluid through the heat exchanger, and also imposes an upper limit of the mass flow rate established by balancing the hydronic system. The upper limit is controlled by a parameter proportional to mass flow rate.
