Features and Benefits

The UniTrane® fan-coil meets the standards of today’s market, as well as the anticipated needs of tomorrow’s market. The tradition that company founder Reuben Trane began 60 years ago continues with the latest generation of fan-coils from The Trane Company.

The UniTrane

fan-coil is the leader in

these key areas:

• Indoor Air Quality (IAQ)

• Controls

• Flexibility

• Quality

• Serviceability

Today’s HVAC market is concerned with issues such as indoor air quality (IAQ) and CFCs that demand a change in HVAC products. In addition, renovation has overtaken new construction in the fan-coil market—demanding a design that caters to renovation issues. Trane is concerned with these issues, too. That’s why we designed the UniTrane fan-coil as an integral part of the company’s system solutions with standard IAQ-related features that fully comply with ASHRAE 62.

IAQ Design

• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.

• The main and auxiliary drain pans are constructed of a noncorrosive engineered plastic (ABS and CyColac T).

• The main and auxiliary drain pans are positively sloped in every plane to assure proper drainage and help maximize protection from microbial growth.

• The drain pans are removable for cleaning.

• Easy filter access encourages frequent changing.

• The auto-economizer damper option allows free cooling and ventilation to help comply with ASHRAE 62—and save energy and operating costs.

• UniTrane fan-coils have a blow-thru design. Low vertical units are drawthru.

Controls

• All controls are factory-mounted and tested to minimize field setup.

• Controls are wired with a 24 VAC transformer to keep only a single source power connection requirement to the unit.

• All wall-mounted zone sensors require only low voltage control wiring from the device to the unit control box. (No line voltage.)

• The Tracer

controls family introduces the latest in control technology with the ZN.010, ZN.510, and ZN.520 controllers.

• The controller automatically determines the unit’s correct operating mode (heat/ cool) by utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active setpoint, allowing total comfort control.

• Entering water temperature sampling eliminates the need for inefficient bleedlines to sense automatic changeover on two-pipe changeover units.

• The random start-up feature helps reduce electrical demand peaks by randomly staggering multiple units at start-up.

• Occupied/unoccupied operation allows the controller to utilize unoccupied temperature setpoints for energy savings.

• Warm-up and cool-down energy features are standard with Trane controls.

• Continuous fan or fan cycling is available with ZN.010 or ZN.510.

• Monitor unit operation using Tracer

Summit building management system with ZN.510 or ZN.520.

• To customize unit control, Tracer Summit or Rover

™

software will allow field modification of ZN.510 and ZN.520 default settings. For ZN.010, use Rover to field modify default settings.

• Maximize fan-coil system efficiency with free cooling economizers and modulating valves on units with ZN.520.

Flexibility

• Two, three, and four-row coils allow greater design flexibility in two and four-pipe systems.

• One-row steam or hot water reheat coils for dehudification on units with ZN.520 controls.

• Fan motors are available for either high static (0.4-inch external static pressure) or free discharge applications.

• Piping is factory assembled, mounted and tested. Units are also available without piping. Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed switch or Tracer ZN.520.

• Factory piping options include interconnecting piping, control valves, and end valves. Deluxe piping also has unions and a strainer.

• Control options range from a simple fan speed switch to a DDC controller that can tie into a Tracer Summit

building

automation system.

• An 8-inch (20 cm) extended end pocket is an available option on the piping end of cabinet style units.

• Slope-top vertical cabinet units are also available for school and dormitory applications to prevent items from being placed on top of the units.

Quality

• Coils and piping packages are air and leak-tested before mounting on the fancoil.

• Coil piping connections are also air and leak-tested after mounting on the unit.

• All control end devices and moving components (fans and motors) are computer-tested after units are complete.

Serviceability

• Filters are easily removable and changed without removing the front panel on vertical cabinet units.

• Motors are easy to disconnect from the fan board, allowing easy service.

• The main and auxiliary drain pans are easily removable and wipe clean with a wet cloth.

• The manual output test function is an invaluable troubleshooting tool. By simply pressing the test button on the

ZN.510, ZN.520, or ZN.010;

Tracer service personnel can manually exercise outputs in a pre-defined sequence.

Piping Packages

Factory-Installed Piping Packages

UniTrane® fan-coils have standard piping packages available as a factory built and installed option, for the main coil. Piping package options are also available for the hot water reheat coil on two-pipe units equipped with either a fan speed switch or Tracer assures all piping packages are fully tested under water for leaks and are built within strict tolerances. Factory-installed means that chilled and hot water pipes are the only field connections required. The installer doesn’t have to sweat connect piping packages onto coil connections in a tight end pocket. Field connections are brought to a point near the exterior of the unit for easy access. All piping and components are located to allow condensate to drain into the auxiliary drain pan. Insulation of the factory piping package is not required. However, all field connections should be insulated to prevent condensation from missing the auxiliary drain pan.

Piping Package Components

UniTrane piping packages consist of a variety of components for each applica-

tion. The following section provides a detailed description of each of the piping components. Following this section are additional illustrations and specifications.

Piping System/Placement

Factory piping systems are available for either two or four-pipe systems with right or left hand connections. Four-pipe systems have both the heating and cooling connections on the same side of the unit. A simple coil connection (a unit without a piping package) is also available in either a right or left hand configuration for those applications requiring field piping.

Interconnecting Piping

Interconnecting piping refers to the copper piping which is attached to the coil connections and to which all other components (control valves, end valves, etc.) are attached. Piping is OD copper. Two-pipe piping extends near the unit exterior to one inlet and one outlet connection.Four-pipe units have two sets of piping that extend near the unit’s exterior—one inlet and one outlet

each for both chilled and hot water. A label identifying connection points clearly marks both chilled and hot water on every unit.

Deluxe or Basic Piping Package

The basic piping package includes only the main components of the piping package: interconnecting piping, control valves, and end valves.

The deluxe piping package also includes a strainer on the entering water pipe and unions at the coil connections along with the basic components. The strainer body is cast brass construction, with a stainless steel mesh strainer that is easily removed for cleaning. The unions are forged brass construction and close with a minimum amount of effort.

End Valves

Each piping package includes a ball valve for the entering water pipe and one of the following end valves on the leaving water pipe: ball valve, manual circuit setter, or an auto circuit setter. These valves serve as the field connection points on all UniTrane piping packages.

• Ball Valves

Ball valves, also known as stop or end valves, allow the unit to be cut off for service purposes. These valves have a two-inch handle that rotates 90 degrees to a fully open position. The valve body is cast brass, and the ball is polished brass with a Teflon seat. Ball valves are available as end valves on both the entering and leaving water pipes.

Piping Packages

Manual Circuit Setter

In lieu of a ball valve on the leaving water pipe, a manual circuit setter, also known as a manual flow control valve, acts as both a flow setting device and a stop valve. This valve allows water flow through the fan-coil unit to be set quickly and accurately.

The manual circuit setter includes Schrader ports in the valve body. These ports are used to measure the pressure drop across the valve. This pressure drop can be compared to factory supplied curves that relate the pressure drop to a specific flow rate. This valve also has a memory stop so the correct setting can be found quickly.

Auto Circuit Setter

An auto circuit setter is an automatic flow control device available on the leaving water pipe. The auto circuit setter includes a cartridge within the valve body that is sized to allow a specific flow rate through the coil. This valve sets flow through the coil without any action required by a system piping balancer. The auto circuit setter is available on the leaving water pipe with a ball valve.

The auto circuit setter also includes two P/T’s plugs in the valve body to allow

measurement of the pressure drop temperature through the valve.

Control Valves

Piping packages are available with or without control valves. All control valve options are factory mounted and wired to the UniTrane

• Two-Way/Two-Position Valves

These valves will either fully open or close in response to a 24VAC signal from the Trane controller. Main control valves are direct-acting valves, while the auxiliary valves are reverse-acting. All control valves are factory mounted in the leaving water pipe downstream of the coil. Some means of relieving pump head pressure should be accounted for when two-way valves are selected. Normally open or normally closed valves are available.

• Three-Way/Two-Position Valves

These valves will either allow full water flow through the coil or divert the flow through a bypass line. The valves respond to a 24VAC signal from the Trane controller. Main control valves are direct acting valves, while the auxiliary valves are reverse-acting. All three-way valve packages include a balance fitting

fan-coil controls.

in the bypass line to allow flow balancing in the bypass position. Three-way valves are factory mounted in the leaving water pipe downstream of the coil. Normally open or normally closed valves are available.

• Two-Way Modulating Valves

These valves modulate the water flow through the coil in response to a signal from the Trane controller. All modulating valves are three-wire floating point equal percentage valves. The modulating valves are factory mounted in the leaving water pipe downstream of the coil.

• Three-Way Modulating Valves

These valves modulate the water flow through the coil in response to a signal. Three-way valves allow water that is directed through the coil to mix with water that is directed through the bypass line. This mixture exits through the leaving water pipe. All modulating valves are three-wire floating point equal percentage valves. The modulating valves are factory mounted in the leaving water pipe downstream of the coil.

Selecting the Correct Modulating Valve Size

Modulating valves are available in any of four port sizes. These four port sizes relate to a Cv of 0.7, 1.5, 2.5 or 4.0, which is the coefficient of flow. The coefficient of flow is defined as the volume of water flow through a control valve in the fully open position with a 1 psig (6.895 kPa) differential across the valve. It is calculated using the following formula: Cv = Q/Square root ∆P where: Cv = flow coefficient Q = flow rate (GPM) ∆P = pressure drop across the valve or coil (psig).

For good control, the valve Cv should be approximately equal to the Cv of the water coil.

Modulating Valve Selection Example

Assume a size 06 fan-coil is selected to operate at the following conditions: Vertical Cabinet Fan-Coil Entering water temperature = 45 F (7 C) Leaving water temperature = 55 F (13 C) EAT conditions = 80/67. The coil is selected as a four-row coil. Select the best modulating valve size for this unit.

1 Find the ∆P across the water coil. Refer to the ARI performance table to determine the ∆P across the water coil (or use TOPSS™ selection program). The water pressure drop is found to be 7.0’ (20.9 kPa) of water at a flow rate of 3.74 gpm. This converts to a pressure drop of 3.03 psig (1.0 feet of water = 0.4328 psig.)

2 Calculate the Cv of the water coil. Cv = GPM/Square root ∆P. Cv = 3.74/Square root 3.03

Note:

1. CFM = Cubic feet per minute

2. TMBH = Total capacity (MBH)

3. GPM = Gallons per minute

4. WPD = Water pressure drop (feet of water)

5. Q/ITD = MBH (kW)/(Entering water temperature - Entering air temperature) when ∆T and GPM (L/s) remain constant. To determine heating capacities at a different entering water

temperature or entering air temp, compute the new ITD and multiply it by the Q/ITD shown.

6. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.

7. High static motors need the appropriate length of duct to prevent poor acoustical applications.
