Carier vvt an alternative for vav system published by morgan popealone160162
VVT (variable volume terminal) systems provide individual zone control of heating and cooling while using a constant volume air source. VVT works by delivering a variable volume of air to each zone as needed using intelligent zone sensors and bypass dampers. It provides better comfort and indoor air quality than single zone constant volume systems. VVT can be cost effective both initially and over time compared to other zoning alternatives through energy saving features and using standard HVAC equipment. Key players in VVT systems take different approaches between value-driven options that optimize total cost of ownership, and price-driven alternatives that minimize up-front expenses.

4. IndustryJargon,TerminologyandAcronyms
• Building Management Systems (BMS) also known as Building Automation
Systems (BAS), Building Management and Control System (BMCS), Direct
Digital Controls (DDC) and Building Controls
• Other terms associated with Control Systems include:
– Supervisory, Control and Data Acquisition (SCADA)
– Programmable Logic Controllers (PLC)
– Energy Management System (EMS)
– Data gathering panels (DGP)
– Modbus, Lonworks, and Bacnet – All refer to communications protocols
– ‘Front End’ – legacy term used to refer to the BMS Operator Workstation
• Most Common Current industry term –
– Building Management System (BMS) or
– Building Management and Control Systems (BMCS)
5. WhatisaBuilding ManagementSystem?
• BMS systems are “Intelligent” microprocessor based controller networks
installed to monitor and control a buildings technical systems and services
such as air conditioning, ventilation, lighting and hydraulics.
• More specifically they link the functionality of individual pieces of building
equipment so that they operate as one complete integrated system.
• Now installed in every major building or facility with the availability of
direct integration into all other building services such as security, access
control, CCTV, fire, Lifts and other life and safety systems.
• Current generation BMS systems are now based on open communications
protocols and are WEB enabled allowing integration of systems from
multiple system vendors and access from anywhere in the world.
8. BMSSuppliersandIntegrators
• Procured as a complete system that includes, engineering, supply,
installation, programming and commissioning.
• Specialist Integrators that are either directly associated with the
manufacturer or are approved re-sellers.
• All Integrators should have full factory technical support
• Need to work closely with Mechanical Services, Mechanical Electrical and
other contractors.
• For new construction BMS is usually included within the mechanical
services package.
• ‘Tier 1 Company’ only refers to a direct factory association and not to the
quality of products or services…
12. TypicalUserInterfaceOptions
Can be a basic LCD display through to
full Graphic Operator Workstations.
The Graphic Interface must be
intuitive to use and not require an
Engineering degree to interpret
They must provide sufficient level of
detail to enable the operator to
determine what is happening and
what is going to happen next
Graphics need to provide access to
parameters for tuning and seasonal
information needs to be built into the
system

29. 4. OperationalConsiderations
Tuning and optimisation
Importance of System Documentation
System Maintenance, what, how often and by whom
Life cycle expectations and considerations
30. Control LoopTuning
• BMS Tuning and Optimisation are not
the same thing….
• BMS Tuning or control loop tuning
ensures that the equipment operates
in a stable, predictable and repeatable
manner.
• Optimisation focuses on operating the
equipment in the most energy efficient
manner without impacting on the
controlled variable
• The first stage of optimisation includes
BMS loop tuning.

32. ImportanceofSystemDocumentation
• Functional Description (FD)
– Details the configuration of the BMS
– Overview of the building services
– Describes in detail each of the BMS control strategies and sequences of
operation
– Documents interaction between each part of the system
• Point Schedules
– Detail all connected devices and their point type
– Critical for planning and system engineering
• Control System Drawings
– Should include a network architecture drawing
– Detail the physical wiring connections to controllers
– Useful for fault finding and establishing spare capacity

34. SystemMaintenance
• The BMS belongs to the building owner who should act as its
administrator managing BMS access rights
• The BMS should be maintained with an appropriate level of servicing
• As with any software driven system, data and files should be backed up on
a regular basis
• Critical components should be identified and checked at regular intervals
• BMS functions such as trend data, reports and alarms can be used to
perform maintenance by exception
• Maintenance should be approached as the performance of the controlled
system not individual components, i.e. AHU or Chiller Plant
• While the BMS equipment vendor should be utilised to maintain the
critical components, other suitably qualified technicians can be utilised for
field equipment
35. BMSLifecycle Considerations
• Considerations:
– Check equipment production cycle status
– Select hardware with proven record (avoid beta)
– Check for level of software and hardware support
– Check for forward compatibility policy
• Equipment Lifecycle:
– BMS field controllers – 15 to 20 years
– Field devices – 15 to 20 years
– BMS computer hardware – 3 to 5 years
– BMS software – Major releases 3 to 5 years
36. BMSTheBasicsExplained–Recap…
