VVT System Overview

A VVT system is an all-air zoning system that provides
individualized comfort to zones using a single air source. It
delivers variable volume of air to each zone based on load
requirements and varies the temperature of the supplied air as per
building needs.

When to Use VVT System?

A VVT system is a great choice for zoning systems due to its
lower installation cost compared to other systems like VRF or VAV.
It ensures comfort and fresh air in each zone, making it suitable

INTRODUCTION TO THE CLIMAVISION DESIGN PHILOSOPHY
Carrier is on a mission to substantially reduce energy consumption in the world’s commercial buildings while improving the comfort and health of the people who work there. ClimaVision achieves this through automation that adapts to change and data that engages people with insights they can use to maintain building systems and operations. To make that difference, automation and data must be present in a much greater percentage of the buildings than they are today, and this can only be accomplished by cutting cost and increasing value.
ClimaVision has adopted a works-out-of-the-box philosophy that redefines the state of the art. Instead of a BAS that can be programmed to do anything, we have created a Climate Control System that is pre-programmed to do most things. Within that pre-programmed manifesto, we still need to account for building variations. To account for these variations while keeping our works- out-of-the-box mantra, we have developed a hierarchy of ways to support variations:
PROFILES — Software and firmware bundles that encapsulate sequences of operation for building systems and terminal equipment.
CONFIGURATIONS — Field settings within each profile that account for equipment differences in systems and terminal equipment.
TUNERS — Parameters and factors within the algorithm supporting sequences of operation that fine-tune the behavior of the system and terminal equipment.
ANALYTICS & NOTIFICATIONS — Predefined analytics and notifications suitable for the selected profiles, and user-defined dashboards and alerts.
The System Design Guides Carrier has prepared are intended to help designers and sales teams determine which solutions are a fit with the type of systems that need control, and how Carrier provides them. The System Design Guide provides a high-level understanding of the requirements sufficient to prepare an initial design at the Profile level and a quotation for a project. Configurations are not discussed here; these would be found in a Submittal when the project arrives at that stage. Tuners are addressed during startup and ongoing support.

VVT SYSTEM OVERVIEW
A VVT (Variable Volume, Variable Temperature) system is an all-air zoning system that provides individualized comfort to zones using a single air source, typically a constant or 2-speed RTU, and zone terminals that are controlled independently.
Variable Volume because it delivers a variable volume of air to each zone, as load dictates. Variable Temperature because the temperature of the air supplied by the central unit varies with building requirements.
VVT AIR SOURCE
Even though VVT systems typically use rooftop units for their central air source, VVT can also be applied to a split system with a packaged air handler. The VPAC (vertical packaged air conditioner) is another good air source for VVT, since it tends to be applied floor-by-floor for renovating existing buildings, where some zoning would be welcome. In essence, the VPAC is the indoor version of the rooftop unit, since it is a self-contained packaged air handler with all refrigeration cycle components included in one factory- assembled package. The only thing needed for VPAC is a cooling tower to reject heat from the water leaving the water-cooled condenser at each unit.

VVT SYSTEM OVERVIEW

VVT systems are a popular solution for heating and cooling multiple zone applications in small to medium size buildings. In addition to the central RTU, VPAC, or split system, the VVT components include the air source unit controller, bypass system, zone dampers, zone and bypass controllers, space sensors, and necessary safeties to protect the system. This design guide will provide the details of the ClimaVision VVT system to ensure the design engineer and sales team have everything needed to ensure a successful system.

WHEN IT IS THE RIGHT CHOICE?

A VVT system is an excellent choice for a zoning system because it offers a typically lower install cost than VRF or other ductless systems and VAV systems while still providing an excellent level of comfort and fresh air to each zone.

VVT versus VAV ­ Choose VVT when… · You want a lower initial cost of the system · Less zones per RTU (typically < 12 zones) are needed

· You have a non-VAV air source · The system requires zoning, but not VAV in
particular

VVT versus Ductless ­ Choose VVT when…
· You want a lower initial cost of the system · You want to avoid installing a separate
outdoor air source

· You have easy roof access in building · There is duct work already in place in a
retrofit application

VVT versus Single-zone Units – Choose VVT when…
· Enhanced control of comfort at the zone level is desirable
· Centralizing and reducing unit maintenance is desirable o Filter changes o Belt adjustments o Economizer adjustments o Yearly maintenance costs

· You want to reduce installed cost by minimizing: o HVAC units o Power supplies and disconnects o Duct system o Rigging, piping and wiring o Roof penetrations o Roof curbs

VVT SYSTEM OVERVIEW
SINGLE-ZONE SYSTEM VERSUS VVT ZONING SYSTEM
Zoning is important in maintaining comfort conditions in air-conditioned buildings. However, rather than using a zoned system, like VVT, many commercial building are zoned using multiple constant-volume rooftop units or similar single-zone units. Tight construction budgets are the primary reason behind these decisions. In such cases, the RTU is controlled based on a single t-stat or sensor located in some zone. In that one zone, the comfort is maintained, but at the expense of the comfort of the other zones. A zoning system like VVT can dramatically improve the conditions for all the zones, a relatively inexpensive add-on in comparison.
Each zone is controlled separately
To overcome uncomfortable conditions, VVT provides additional control zones at minimal additional cost. A space sensor and a VVT damper controller added to each zone will help to provide comfort to all occupants. This allows the same kind of constant or 2-speed equipment to function on a zoned system without the additional equipment cost normally associated with a zoned system air handler. Although zoning helps to ensure comfort, it does not come without some cost. There is a tradeoff in zoning between customer comfort and installed system cost. More zones provide improved comfort for an additional fee. It is important to evaluated the value of comfort that is added by zoning and the price the customer is willing to pay for it. There is usually a middle ground somewhere between inadequate zoning and ultimate zoning that is acceptable.

CLIMAVISION VVT SYSTEM KEY BENEFITS AND FEATURES

SIMPLE TROUBLESHOOTING
ClimaVision provides many tools to help operators understand and troubleshoot their HVAC systems.
How is the ClimaVision VVT system simple to troubleshoot?
· Trends and alarms, along with alarm notification options, help to pinpoint when and where a trouble condition occurred.
· Heatmaps provide a quick-glance overview of building comfort conditions, making it easy to see any hot/cold spots in the building.
· Custom Heatmap Filter: This feature allows the user to apply color coded filters to zones in the heatmap based on specific conditions. Early notifications about problems allow building management to respond to equipment failures before they become more problematic.
· Access to system points from a variety of user interfaces:
· ClimaVision Web UI: Powerful and fullfeatured interface to navigate and manage the system.
· Central Control Unit (CCU): The CCU has a 10″ tablet interface with intuitive access to the system.
· Mobile Apps: Two mobile apps are available: the Facility app, which provides a similar interface to the CCU, providing full access to the system. Also available is the Occupant app, which gives the tenant the ability to adjust the setpoint and schedule override in their specific area.
· Controller User Interface Screens: The built-in screens provide a menu- driven navigation of status, parameters, and setup info for the specific controller.
GET NOTIFIED OF PROBLEMS
The ClimaVision Alerts feature allows the facility manager and/or the servicing contractor to monitor the performance of their HVAC equipment and take corrective action if their equipment is not performing as expected. The facility managers who monitor these systems can be notified and can mute/unmute notifications based on their preferences and requirements.

How does the ClimaVision system support alerts and notifications? · With the Alerts feature, the primary facility
manager can: · Choose their preferred alert method ­ SMS
text, email, push mobile notifications, and/or desktop notifications. · Get notified of any alert per their preferred method.
· Mute/unmute alert for specific equipment for a preferred time duration (per user muting).
IDEAL FOR MECHANICAL CONTRACTORS
ClimaVision is ideal for mechanical contractors because it provides a robust HVAC controls solution that is simple to install and maintain.
There are a number of reasons why 87% of buildings under 50,000 square feet don’t have building automation systems today. Two of the biggest reasons are the overall cost of the system and the expertise typically required to install and support these systems. The ClimaVision system seeks to change that by reducing the installed cost and ensuring it is simple to install.
What makes the ClimaVision system easy to install & how does it reduce cost?
· Built-in control algorithms that are flexible and field configurable. No custom programming is required. During the installation process, the installing technician simply chooses the equipment type and desired features.
· The wireless controller-to-controller network feature reduces time and installation cost. With ClimaVision’s 900 mHz wireless mesh network, the installer does not need to worry about wiring problems. The only thing the installing contractor will need to keep in mind is the recommended spacing between controllers to ensure the wireless mesh network functions effectively.

CLIMAVISION VVT SYSTEM GUIDELINES

SYSTEM SIZING

Duct Sizing Tips ­ Review these excellent tips for sizing ductwork associated with VVT.

· Main ducts at 1200 fpm maximum · Branch ducts at 1000 fpm maximum · Use equal friction or static regain method · Target friction rate = 0.08 in. wg / 100′ EL · Aerodynamic fittings ­ especially near unit
Sizing Bypass Duct and Damper
· Determine air source unit total cfm based on block load
· Find the zone with the smallest airflow (cfm) requirement
· NEVER size for less than 75% of unit design cfm · Size duct and damper to the same size · Bypass cfm = total cfm ­ (smallest zone cfm +
ventilation cfm of all other zones) Example: 5-ton RTU providing 2000 cfm. 3 zones with design airflows of 400, 600, and

1000 cfm. Total ventilation requirement 300 cfm. Bypass airflow is 2000 – (400+300) = 1300 cfm. This is smaller than 75% of unit airflow, so size bypass for 1500 cfm @ 1000 fpm. 18-inch round duct would flow 1500 cfm at ~860 fpm.
Bypass Design Guidelines
· Layout bypass to avoid short circuiting
· Locate static pressure pickup five duct diameters downstream of bypass damper in a straight run (avoid elbows and tees)
· Facilitate mixing of bypass air with return air

Notes: 1. The CCU will pair with a maximum number of 48 ClimaVision devices; however, the
recommended design best practice maximum is 35 nodes. VVT design best practice is 2 to 12 zones.
2. ClimaVision 900Mhz Wireless Mesh Range: The general rule of thumb for standard design is 100′ point to point (or device to device) with a maximum of 2 hops from the CCU to the furthest controller (Max range of 200′ from the CCU to the furthest device)
3. Position the CCU as close to the center of the system as possible for maximum coverage.
4. Walls, concrete, metal, and other RF devices can cause a network signal degradation.
5. ClimaVision devices support a wired connection in the event that using the 900Mhz wireless mesh network is a problem for some reason.

CLIMAVISION VVT SYSTEM SEQUENCE OF OPERATION
Carrier ClimaVision VVT operates to provide comfort to each zone while also maintaining an optimal duct pressure in the system using a bypass damper.
Once you select the VVT-C terminal profile under SmartNode VVT-C profiles, the configuration provides the options to define the damper types, size, shape, and zone priority. It also provides the options to define the minimum and maximum damper positions during heating and cooling along with the Temperature Offset.
Additionally, the profile provides options to modify the controls based on the Internal Air Quality and CO2, with the IAQ and CO2 control that can be enabled or disabled.
Normally the Algorithm continuously tracks the current temperature of the zone and looks for the change in the difference between the terminal level Desired Temperature and Current Temperature and provides an optimal damper opening position within the dead band range, which is a resultant of the loop output based on the PI loop for control signals.
When the Current Temperature increases above the set point or desired temperature, the zone calls for cooling from the system or building-level equipment.
And when the Current Temperature decreases below the set point or desired temperature, the zones call for Heating from the system or building-level equipment.
The building or system-level device is an RTU or AHU which is controlled by the system-level VVT-C profiles.
When the CO2 or the IAQ control is enabled, the algorithm takes the target and threshold values of CO2 and VOC into consideration. An increase in the value from the threshold value results in a loop output, and it changes the minimum damper position for the actual control to the changes in percentage value.
This resultant loop output is called the CO2 loop output, which is simply the weighted average CO2 loop output for all the zones that have CO2 control enabled.
Example- If the target and threshold are 1000ppm and 800, measured CO2 is 850 and configured damper limits are 0-100. The algorithm starts raising the minimum damper position proportionally from 800. A CO2 measurement of 850 will yield a loop output of 25%. This raises the damper’s min position so that it now varies in the range of 25 ­ 100 based on temperature.

CLIMAVISION SPECIFICATIONS FOR VVT AND SINGLE ZONE SYSTEMS

System Description

The Building Automation System (BAS) shall consist of a complete network of controllers communicating via a self-healing, 900mHZ mesh communication network. System shall support both single-zone unitary equipment as well as air-side zoned system applications.

The primary method of interface with the BAS shall be via a web-based server. Server shall support multiple levels of access including Installer, Facility Manager and User. Persons that have access to multiple sites using the same BAS shall be able to login using a single username and password, server shall discriminate regarding information available for each site according to the persons access level at that individual site.

BAS server shall support access via a standard PC or tablet-based web-browser application, as well as appbased access using either Android or Apple iOS mobile applications that are available as a free download from their respective sites. BAS shall have a mobile application specifically for User access, supporting setpoint override adjustment and the ability to add a vacation schedule. A Facility Manager mobile application is also required that can give access to system-level activities consistent with the web-browser application.

BAS shall have an on-site Wi-Fi internet gateway with an owner-provided internet access point. The gateway shall be provided with a touch screen display that allows for registration and configuration of the control system and controllers.

BAS shall include the capability of serving BACnet objects to 3rd-party BAS providers.

In addition to the above features, the BAS shall also offer the following:

· The ability to create normal, special event or holiday schedules at the site or individual zone level
· Predefined trends with grouping of relevant data · Floorplans with temperature heatmap and the
ability to create custom heatmaps to represent other relevant data with colors · Automatic updates for web UI, mobile apps and

controller firmware · Alert notification configuration managed by user · Allow for creation of custom summary tables to
show data points from multiple zones to be displayed/edited in a tabular format · Security – SOC 2 compliant and VAPT certified · Equipment graphics with most relevant data points automatically generated

Controller Capabilities
Controllers shall utilize factory written and tested control algorithms to ensure consistency and quality of the application. Where applicable, applications shall conform to local codes, guidelines, and applications such as Title 24, GL36 etc. Controllers that do not conform to these guidelines and are not listed with the relevant authority having jurisdiction are not acceptable.
All controllers shall have an on-device display. Controller applications shall reside in their respective controllers and be selectable using the on-device function buttons/display. Controllers must be capable of operating in stand- alone mode without connection to the internet/internet gateway.
Installation and Support
BAS shall be installed by factory trained and tested installers. Installers shall carry an inventory of commonly used BAS components or shall alternatively be supported by a local stocking Distributor that has them available. Commonly used components include, but are not limited to: Internet gateways, controllers, sensors and positioning devices. Systems that are not supported within 100 miles of the installation location and do not have locally available replacement components are not acceptable. Approved Vendors: Carrier ClimaVision

Notes: 1. The CCU will pair with a maximum number of 48 ClimaVision devices; however, the recommended design best practice maximum is 35 devices. VVT design best practice is 2 to 12 zones. 2. ClimaVision 900Mhz Mesh Range: The general rule of thumb for standard design is 100′ point to point with a maximum of 2 hops from the CCU to the furthest controller (Max range of 200′ from the CCU to the furthest device) 3. Locate the pressure pickup in the area of least turbulence, 5 duct diameters downstream of the bypass takeoff but upstream of the first zone takeoff or first major junction (Avoid elbows and tees). 4. Transformers need to be sized to accommodate the VA draw of the controllers and sensors being powered. For project specific calculations, see the Product Data sheets of the selected devices for exact VA requirements. 5. Damper kits are available in 6″, 8″, 10″, 12″, 14″, 16″, 18″ & 20″ sizes. Each kit includes the damper, actuator, duct sensor and SmartNode mounting bracket (SmartNodes are sold separately). 6. Carrier recommends using the ClimaVision pre-terminated wire between controllers & communicating sensors. Wire available in various lengths (3 Wire – 18″, 30′, 50′ or 100′)(4 Wire – 25′ or 50′). 7. Wall Sensor – 7C-SE-C43K-X (Temp/Hum) shown can be replaced with MultiSensor – 7C-SE-C72X-X (Temp/Hum/CO2/Occ) or HyperSense – 7C-HS-C1W-X (Temp/Hum/Occ/CO2/VOC/lm/dB)(HyperSense requires 4 wire)
