Switching and Control Devices Planning Guide Pump performance Control Pump performance control Load-conditioned excess pump performance Circulating pumps for central heating and air-conditioning and the hydraulic pipe system as well must by necessity be designed to be capable to meet the maximum design load at minimum outside temperatures. These maximum load conditions do however exist only on a very few days during the course of the heating / cooling season. A typical load factor curve for a central heating system is shown on the graph. Centralised and decentralised control systems intervene continuously in the installation hydraulics in order to make adjustments to accommodate the actual load situation; in most cases, they cause a reduction of the flow volume while at the same time increasing the pump delivery head. Such operating states are non-economical for pump operations, because lower delivery heads would in fact be sufficient, particularly for low flow volumes; in addition, the noise levels that would result must be avoided under all circumstances.
