Clipsal 500 V8 SuperCar Race Pavilion Project Profile

Innotech Clipsal500 1 sm
 
Project Name: Clipsal 500 Pavilion by Emtrol
 
Location: Victoria Park, Adelaide
 
Main Goal of Project:
  • Provide controls for seven temporary skid-mounted air change package ACUs with evaporative precooling, at the Clipsal 500 V8 SuperCar race, including remote and local real-time monitoring of zone temperatures, ambient conditions, damper positions and logging all aspects of ACU operation for comprehensive post-event analysis.
 

Main Requirements of Project

 
  • Remote and local monitoring via 3Gmodem
  • All controls and control-wiring to be contained on each ACU platform.
  • Separate heating, cooling and pre-cooling set points.
  • Evaporative pre-cooling of supply air and independent switching set points.
  • Evaporative water purge and supply solenoid control for each package unit.
  • Supply Air Fan run and fault status with alarms.
  • Compressor fault status with alarms.
  • High-selected zone temperature control of up to 3 separate zones.
  • Minimal wiring due to temporary nature of application (13 sensor cables and 1 actuator cable).
  • Ability to fine tune and adjust during the event, both locally and remotely.
  • Supply-air flow control (VAV) for individual zones on common ACU, for temperature regulation.
  • Monitoring of ambient temperature and humidity.
  • SMS notification to ‘on-call’ staff of individual alarms.
  • Logging of:
    • zone temperatures
    • ambient temperature
    • ambient humidity
    • dew point
    • supply-air temperatures
    • compressor staging
    • set point adjustments
    • supply fan status (pressure switch)
    • evaporator pump call
    • heat/cool demand percent
 

Features/Details

 
Controls Used:
 
Software Used: A variety of applications are catered to using the following software:
 
Heating: 100% Fresh air - each ACU system uses a single stage of DX (Direct expansion) heating.
 
Cooling: 100% Fresh air - each ACU system uses evaporative cooling through a heat exchanger, followed by 2 stages of DX cooling.
 
Data Logging:
  • zone temperatures
  • ambient temperature
  • ambient humidity
  • dew point
  • supply-air temperatures
  • compressor staging
  • set point adjustments
  • supply fan status (pressure switch)
  • evaporative pump call
  • heat/cool demand percent
 
 

Overview

 
What unusual issues has this Project posed?
  • The entire system including ducting is required to be dismantled and stored for most of the year. The units are run 24/7 for the four-day event.
  • Remote and Local monitoring.
 
How did we overcome them?
  • The temporary nature of the structure requires controls to be mounted on each ACU assembly as it is disassembled and stored at the event end. All controls, supply-air sensors and airflow switches are mounted locally at the ACU on a pre-fabricated skid, and fork lifted in to place every year. This leaves only minimal (and cost effective) temporary wiring every year – a 100m LAN and the zone temp sensors.
  • Network access and monitoring is via 3G modem. 
 
Which controls/software were used to address each requirement?
 
Maxim II LD:
  • All HVAC control functions and logging
 
FM Explorer:
  • Fault Monitoring and Annunciation
 
Facility Manager Server Software:
  • Fault Monitoring and Annunciation. SMS notification of exact alarm.
