Introduction

Choosing the best flow control balancing device for water-source heat pump equipment just got easier.

Superior circuit balancing of the HVAC equipment is an important aspect to the overall layout and design of the HVAC system. Proper balance of the system can protect the HVAC equipment, while providing a longer equipment life. Superior circuit balancing can save energy by supplying the proper amount of fluid to make your system perform at its highest efficiency.

Trane’s flow balancing choices have taken the guess work out of system balancing. From the most

economical means of system balancing, to an automated flow system, Trane’s flow kits support a variety of water-source heat pump applications.

The three hose kit choices used in HVAC systems today include:

• Manual Hose Kit with a ball valve

• Manual Hose Kit with a circuit setter

• Automatic, Self-balancing Flow Hose Kit

With flow velocities ranging from 0.5 to 60.0 gpm, our automatic balancing device supports a

variety of water-source heat pump applications and equipment sizes. It is typically the ideal choice in system balancing, but up-front expense associated to auto flow balancing often deters owners into a manual balancing system.

With automatic flow balancing, the actual money spent on the automatic flow kits, can be quickly

made up when the tedious work of balancing, and re-balancing the system is recouped by the installing contractor. And in the event that a new piece of equipment is added to the system, or equipment servicing is required, re-balancing of the entire system is necessary.

Overall accuracy in the balancing of water flow to the equipment may also be in question when using the manual balancing method. Especially in applications where varying cooling requirements may offer a substantial energy savings to the owner. In this application, manual balancing to support varying pump speeds is not practical.

Automatic flow kits are an excellent choice in providing protection through a constant, accurate

flow to the equipment.

Regardless of your balancing choiceandneed,Trane suggests several alternatives. All hose kits are model number configured to better support a range of decisions made in any given application.

Quality components are an important aspect to installing a fail-proof system. Our hose kits are tested at the manufacturing site to help ensure leaks are non-existent. All flow kits are outfitted with a braided, stainless steel hose on both the supply and the return side of the system.The available hose length options are 18-, 24-, and 36-inches.

Optional components, such as a Y-ball strainer, sustain systems using brackish or hard water. A 2position isolation valve may be specified in the hose kit design for systems supplying variable water volume control.

For questions in entire system balancing for overall life cycle savings, Trane has the answer.

Features and Benefits

Manual Flow Control

Ball Valve Flow Control

Traditionally, the first choice in a balancing device on a water-source heat pump application is the

lowest first cost option. In water-source heat pump fluid flow balancing, this typically employs a manual balancing (ball valve) device with hoses. This method utilizes pressure/temperature (P/T) measurement ports on the ball valves at the entering and leaving side of the heat pump so that pressures and temperatures can be measured within the water piping.A ball valve is then manually throttled to change the amount of flow to the unit to reach the desired temperature or pressure differential.

Advantages

• Low first cost

• Direct access to the water-loop through P/T port for future trouble shooting

• Temperature and pressure measurements can cross check balancing

• Better water temperature measurement than external sensors

Disadvantages

• Flow accuracy of ±25%

• Eachunit must be balanced multiple times because of changing system conditions in balancing other units

• Integral differential temperature balancing is less accurate than differential pressure balancing

• Pressure drop of hose and fittings must be accounted for in differential pressure measurements

Circuit Setter Flow Control

Another choice in manual fluid flow balancing of a water-source heat pump includes a Hays

Measurmeter circuit setter flow control option.This manual balancing method uses an in-line flow measurement device and an adjustment feature to measure and set flow rates at each heat pump.

Advantages

• In-line flow measurement device

• Easier to use than traditional or differential pressure/differential temperature methods

Disadvantages

• Flow accuracy of ±20%

• Higher pressure drop of circuit setters result in additional pumping energy costs (a 3/4-inch circuit setter with 8-GPM flowing has 15-feet of pressure drop)

• Direct readout of flow rate is not possible with a circuit setter

• Eachunit must be balanced multiple times because of changing system conditions in balancing other equipment

Features and Benefits

change (through further addition of heat pumps, for example) each individual flow control valve will automatically adjust to the new system conditions.

In variable water volume applications, there can be large variations in the system water pressure.

These pressure changes can adversely affect the system balance and heat pump operation. A self

balancing hose kit can provide continuous balancing in this application because of its ability to automatically adjust to the varying system conditions.

Advantages

• Flow accuracy of ±10%

• Broader application in variable water volume pumping systems

• Greater flow accuracy results in operation closest to design, with least tenant complaints

• Only one pressure differential range of 2 to 80 psid

• Labor savings during balancing can offset increased material cost

• Same or less cost as manual balancing hose kits on smaller diameter hose kits

Disadvantages

• Greater first cost over other manual balancing methods

Self-Balancing Hose Kits

The Hays self balancing valve contains a rubber diaphragm that is designed to flex into a contoured

orifice plate. This allows the valve to decrease the water flow path as pressure increases. The pressure differential ranges of a Hays automatic valve covers 2 to 80 psid diaphragm against the fixed orifice plate makes the Hay’s valve difficult to clog and resistant to cavitation damage. Outside of the pressure differential window, the controller continues to perform as high as 150 psid, but does not become a fixed orifice.

Note: The Hays self balancing valve is a constant flow rate device that contains a variable orifice

to govern water flow. Since it is a variable orifice, it can not be described with a Cv or a pressure drop at a given flow for piping system design purposes. Conversely, the designer may assume a constant flow rate over the pressure differential range of 2 to 80 psid uses constant pressure in system design.

Page 12

Features and Benefits

There are three features that every self-balancing valve should possess to accomplish the job of

automatically balancing an HVAC system in the industry.The valve should be:

• Non Clogging

• Quiet

• Accurate

Non-Clogging. The live flexing action of the elastomeric diaphragm against the orifice seat

permits passage of reasonably sized particles of sludge, rust balls, thread chips, and other debris. Because the working parts are of a two piece design, they are resistant to fouling. Back pressure forces the diaphragm away from the orifice seat allowing any debris to be back-flushed away. Hays is the only balancing valve that provides unrestricted flow during back flush.

Quiet. By design, the Hays automatic balancing valve is inherently quiet. The only moving part

is an elastomeric polymer diaphragm in an orifice seat that is made from polyphenylsulfone.

Together, these materials have a natural sound deadening ability.The Hays valve neither clicks nor

is noisy, and has only one control range.

Accurate. What does accurate mean? Is it the stable, predictable delivery of thermal energy in a

hydronic system?The Hays valve is accurate ±10%, that equates to 99.8% heat transfer. Because the polymer diaphragm compensates for changes in fluid temperature the valve provides stable thermal system performance. The addition of antifreeze to the fluid further increases the need for the offsetting characteristics of the Hays automatic valve.
