AZEVAP Integrated Control System (AZCONTROL)

The AZEVAP Integrated Control System (AZCONTROL) is the infrastructure formed by interfacing and connecting AZSCADA with system and component Input / Output devices such that the individual components and systems are controlled to act in harmony to achieve facility level performance consistent with client objectives. Namely, the component level control and data collection Input / Output interfaces are connected digitally to AZSCADA where system level analysis and control functions are applied to facilitate component and system performance monitoring, control, and management functions.

AZEVAP Supervisory Control and Data Acquisition (SCADA)

AZSCADA is the backbone of the AZCONTROL; this proprietary Supervisory Control and Data Acquisition (SCADA) product incorporates innovative human machine interface (HMI) capabilities, as well as, a wide array of built-in configuration characterization elements and algorithms for component, system, and facility level control. These features and capabilities make AZSCADA flexible and scalable and easily tailored and adapted to client specific facility location, HVAC component configuration, and facility performance needs without additional programming. AZSCADA further supports reliable, safe, and secure client local and remote grouped access by authorized personnel to monitor and manage HVAC component, system and overall facility performance. The Linux based AZSCADA package can be installed on a virtual drive on a facility server or on a micro-computer connected to the Local Area Network (LAN) behind the facility firewall.

AZCONTROL Input / Output devices

AZCONTROL component Input / Output device selection depends on the components ability to communicate with the LAN. Connecting the components to the LAN can be accomplished using Ethernet cables or via wireless communication.

  • AZFlow Coolers are built with an integrated Opto-22 I/O package that interfaces with AZSCADA via LAN (Wireless or Ethernet Cable) and cooler water application control, cooler blower VFD, cooler sensor package, and building area Temperature and differential pressure sensor package
  • opto panel
  • AZEVAP exhaust fan Variable Frequency Drives (VFD) have a built in Ethernet communication capability such that they are connected directly to the LAN.

AZCONTROL operations and associated AZSCADA control screens

AZCONROL provides a number of operating modes for controlling the coolers and exhaust fans to control the building environment. Namely:

  • Computer Mode – parameters are set via a computer screen
  • Schedule Mode – parameters are set in a 24 / 7 timeline schedule
  • Outside Conditions Mode – parameters are controlled using outside temperature and humidity
  • Building Temperature Mode - parameters are controlled using average building inside temperature
  • Building Differential Pressure Mode – Exhaust fan parameters are controlled using building differential pressure
