Web3 de jun. de 2015 · For hot deck/cold deck systems, the key opportunities are: Reconfiguration of controls to minimise simultaneous heating and cooling. Improved fan control. Replacement/repair of face/bypass dampers to reduce leakage and possibly to provide independent hot/cold damper control (multizone systems). This can be achieved … WebContinuity is the presence of a complete path for current flow. A closed switch that is operational, for example, has continuity. A continuity test is a quick check to see if a circuit is open or closed. Only a closed, complete circuit (one that is switched ON) has continuity. During a continuity test, a digital multimeter sends a small current ...
