Objectives Finish duct systems Learn about plumbing systems Discuss your question relate to HW4 Introduce some project topics

VAV Operation

How to use multiple pumps

Dampers

Summary of Air Distribution Systems Select diffuser based on ADPI Given a layout of duct system Calculate total pressure drop Deal with non-circular ducts and fitting losses Select the fan based on fan and duct curve

Hydronic Terms Head loss Open-loop vs. closed loop

Head Loss

Fittings

Pumps Driving force to move air water in buildings Raise pressure and produce flow One main type Centrifugal

Pump curves NPSHR = Net Positive Suction Head Required

Plumbing Arrangements

Project Design problem …. Research problem

Couple chiller and cooling tower TCTS TCTR Weather parameters P - Find COP for several weather condition Use nonlinear equation solution methods TCWS TCWR Q

HVAC Control Economizer (fresh air volume flow rate control) fresh air damper filter cooling coil heating coil filter steam humidifier fan mixing

Sequence of operation (ECJ research facility) Set Point (SP) Mixture 2 Mixture 3 Mixture 1 DBTSP DPTSP Control logic: Mixture in zone 1: IF (( TM<TSP) & (DPTM<DPTSP) ) heating and humidifying Heater control: IF (TSP>TSA) increase heating or IF (TSP<TSA) decrease heating Humidifier: IF (DPTSP>DPTSA) increase humidifying or IF (DPTSP<DPTSA) decrease humid. Mixture in zone 2: IF ((TM>TSP) & (DPTM<DPTSP) ) cooling and humidifying Cool. coil cont.: IF (TSP<TSA) increase cooling or IF (TSP>TSA) decrease cooling Humidifier: IF (DPTSP>DPTSA) increase humidifying or IF (DPTSP<DPTSA) decrease hum. Mixture in zone 3: IF ((DPTM>DPTSP) ) cooling/dehumidifying and reheatin Cool. coil cont.: IF (DPTSP>DPTSA) increase cooling or IF (DPTSP<DPTSA) decrease cooling
