Description

DIRECT GAS-FIRED MAKE-UP AIR SYSTEM
FIELD OF THE INVENTION

[001] The present invention relates to the field of make-up air units.
SUMMARY OF THE INVENTION

[002] It is an object of the present invention to provide a direct gas-fired make-up air system comprising an inlet and an outlet to transport outside air to the inside (of a building or spray booth) through a duct, said duct comprising a variable speed fan, at least one burner for fuel combustion, at least one probe to measure airflow at said burner, at least one damper controlled by an actuator for airflow adjustment and a controller programmed to adjust said damper and said fan to stabilize airflow at said burner for complete combustion of gas in said burner, said controller being configured to cause said fan to accelerate from a stationary state to an operational speed at a full acceleration rate of said fan, and to cause said burner to begin combustion at said operational speed, whereby start-up time is decreased for burner ignition such that cold air inflow during the startup process is minimized.

[003] In some aspects of the present invention, the make-up air unit supplies air to a spray booth.

[004] In some aspects of the present invention, a quick startup is achieved by lowering the fan speed threshold at which burner ignition occurs while simultaneously probing for dangerous combustion by-products to ensure safe operating conditions [005] In some aspects of the present invention, the burner is ignited at a fan speed representing 40% of maximal speed [006] In some aspects of the present invention, the fan acceleration slope dictated by a variable frequency drive is maximal until reaching the minimal threshold required for burner ignition and decreases thereafter to prevent fan speed variations that would otherwise cause said airflow variations to shut off said burner or result in suboptimal combustion .

[007] In some aspects of the present invention, the start-up time is minimized by rapidly attaining (through rapid damper actuators and rapid fan speed changes) a set of pre-established values of airflow before burner ignition can occur, at which time more gradual variations can be used to prevent burner shut off or suboptimal combustion.

[008] In some aspects of the present invention, the start-up time is minimized by a variable frequency drive which allows for rapid fan speed changes [009] It is an object of the present invention to provide a direct gas-fired make-up air system comprising an inlet and an outlet to transport outside air to the inside through a duct, said duct comprising a variable speed fan, at least one burner for fuel combustion, at least one probe to measure airflow at said burner and at least one damper for airflow adjustment, said at least one damper controlled by a fast-acting actuator ensuring constant airflow at said bumer during rapid fan speed variations that would otherwise cause said pressure differential to shut off said burner or result in suboptimal combustion.

[0010] In some aspects of the present invention, a fast acting damper actuator allows the slope of fan speed variation after burner ignition to be greater than would be possible without said fast-acting damper actuator.

[0011] In some aspects of the present invention, the amount of air evacuated is limited by the amount of make-up air entered, thus limiting the potential for negative pressure inside the spray booth.

[0012] In some aspects of the present invention, an alarm sounds if the make-up air intake cannot compensate the evacuated air.

[0013] In some other aspects of the present invention, the comfort to a spray booth user comprising installing the system described above.

DETAILED DESCRIPTION
REASONS WICH REQUIRES A TSSA VARIANCE APPLICATION
Applicants provides a solution to modulate exhaust fans on-demand called NOVEO-AIRTM or ECOHOODTM. This solution has a huge environmental impact as well as an economical and safety positive impact. Most of the existing Make-up units are fixed volume type, two volume type or variable. Most of the installed units are from the first two types since variation was not a preoccupation in HVAC industry. Recent studies have shown that exhaust variation produces tremendous energy savings and increases the quality of manufactured products.
The installation of NOVEO-AIR variable exhaust solution then requires the variation of the air intake. In order to face this new situation, we have the choice of either replacing fixed volume units by variable by design units or modify existing ones. The modification option is obviously a preferred one since it upgrades the quality of existing equipment; increases comfort level and make the unit "smart" by adding intelligent controls. Cost wise, the modifications are installed at half the price of a new unit.
All the above implementations are all made without affecting the safety of the units.

Safety precautions [0014] The MUV system cannot be incorporated in any device that would present danger to the human body or from which malfunction or error in operation would present a direct threat to human life (nuclear power control device, aviation control device, traffic device, life support, safety device or fire extinguishing device). If the system is to be used for any special purpose other than modulating exhaust in spray booths, please contact the manufacturer.

[0015] This equipment is not to be used with equipment in which a malfunction error would cause an accident.

[0016] WARNING! The Noveo system should ONLY be installed by a qualified electrician and certified gas technician.

[0017] WARNING! Even when the motor is stopped, dangerous voltage is present at the Drive power circuit terminals.

[0018] WARNING! Dangerous voltage is present when input power is connected.
After disconnecting the supply, wait at least 5 minutes (to let the intermediate circuit capacitors discharge) before removing the cover.

[0019] Do not install or operate the MUV system if it is damaged or a component is missing.

[0020] This product is designed to be used with make-up air units that provides make-up air to satisfy an exhaust system within a building. Normal discharge temperature is in the 65 F - 75 F
range.

[0021] WARNING! Fire or Explosion hazard can cause property damage, severe injury or death.
Ensure that a!l air taken into the unit is free from the presence of:

[0022] Flammable solids, liquids and gases.

[0023] Explosive materials. Example: grain dust, coal dust, gun powder etc.

[0024] Substance which may be come toxic when exposed to heat or passing through a gas flame.

[0025] Transportation [0026] When transporting or carrying, do not hold panel by front cover. This may result in dropping the unit and result in injury.

Motor considerations [0027] A motor insulation system that is subjected to thermal and environmental stress may be at the limit of its capability to withstand dielectric stress regardless of the waveform of the applied voltage. Proper attention must be paid to limiting voltage stresses.

[0028] The motor must be properly selected to remain within suitable operating temperature limits.
This means selecting a motor that is suitable for the ambient temperature and load requirements.

[0029] Always use TEFC (Totally Enclosed Fan Cooled) motors.

[0030] Note that long motor cables can contribute to performance problems other than the motor insulation voltage stress concerns that are discussed here. Additional concerns include excessive voltage drop between the controller and motor, problems caused by high frequency ground leakage current and problems caused by line-to-line capacitance between the conductors of the motor cable.

Using an Existing Motor [0031] If thermal damage to existing motor is unknown, then the remaining life cannot be forecast.

[0032] General purpose motors have a wide range of capabilities for withstanding fast rising pulses of high peak voltage. Because of the insulation system design variation, peak voltages withstand capabilities range from less than 1000V to more than 1600V. In using an existing motor, it is important to remember that the remaining useful life of the insulation can not be accurately determined. Even though standard motors are commonly used successfully with drives, drive duty places higher levels of dielectric stress on the motor insulation than are normally present under sine wave duty. If the motor insulation is nearing the end of its useful life, connecting the motor to a drive may lead to more rapid insulation failure. It is always prudent to seek the advice of the motor manufacturer. Only the manufacturer of a particular motor can determine the peak voltage withstand capability of that motor. If the motor manufacturer says that a particular motor model is not suitable for PWM duty or use with drives, a new motor should be installed.

[0033] If the motor manufacturer says that similar motors have been successfully used with drives, it is still important to consider the age and condition of the motor. Rewound motors must not be used with VFD.

[0034] Whenever drive is connected to an existing motor with a motor cable length exceeding 50 feet, the most conservative approach is to use an inverter output reactor. The use of an output reactor is usually the most convenient and economical means of minimizing the possibility of motor insulation failure due to the voltage stress caused by the interaction between the inverter waveform, the motor cable and the connected motor. Since the quality and condition of the motor insulation is unknown, an output reactor can only minimize, not guarantee, the risk of insulation damage.

Motor Selection [0035] Whenever a new motor is selected for use with a drive, use a motor that is recommended by the motor manufacturer as suitable for use with an variable frequency drive.

[0036] Several motor manufacturers are currently providing motors that meet this requirement and additional motor manufacturers are soon expected to meet this requirement.
Some motor manufacturers may recommend only inverter duty motors for use with drives while others may designate certain models of general purpose motors as suitable.

Installation [0037] Do not place flammable objects nearby.

[0038] Do not install in a location where the control panel could come in contact with water, vapour and other fluids.

[0039] Do not install in area where the unit would be subject to excessive of vibration. This could result in the unit falling, resulting in injury.

[0040] The Control panel must be installed on a base or a wall that can support the unit's weight.

[0041] Do not disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your distributor.

Operation [0042] Do not operate the unit with front covers open or removed.

[0043] ASSESSMENT OF SAFETY RISKS

[0044] The modifications are relevant to airflow and the add-on controls do not change in any manner the existing safety apparatus, interconnection to the gas train, or flame safety devices.

[0045] In reference to CSA B149.3, paragraph 9.1.2, combustion safety controls remain intact as there were installed by the equipment manufacturer. Paragraph 9.1.2 states "an airflow proving device of the differential type, or an approved equivalent, shall be provided..." Existing Differential Airflow proving devices and their control circuits remain intact. Additional pressure pickup tubing is installed and connected to a pressure transducer or dual-pressure switches added to maintain proper differential pressure through the burner. Added tubing will not affect safety controls.

[0046] The modifications are described below:

[0047] Installation of one or multiple dampers in the airflow beneath and/or above the burner area in order to maintain the appropriate air flow through the burner. A pressure transmitter coupled to a PLC or a dual-pressure switch is installed to insure proper pressure differential through the burner.

[0048] Installation of one or multiple damper actuators to modulate the above dampers.

[0049] Replacement of the remote status panel by a NOVEO (MUV-R) remote control panel.

[0050] Installation of a Variable Frequency Drive [0051] Replacement of the blower motor by an Inverter Duty type motor.

[0052] Installation of a NOVEO Control Panel (MUV) including a PLC that will have the following inputs and outputs:

[0053] Inputs :
a. Building Room Temperature (optional) b. Discharge Temperature c. Outside Air Temperature d. Building Pressure e. Bumer Profile Plates Differential Pressure f. Exhaust Air Volume (optional) g. Make-up Air VFD output signal [0054] Outputs:
a. Make-up ON/OFF fan command b. Make-up modulating VFD fan speed command c. Make-up ON/OFF heat command d. Make-up modulating heat command e. Make-up modulating derivation damper command f.

[00134] CO Sensor Installation [00135] The CO sensor is requested by TSSA approval in Ontario. Install the remote sampling tubes in the supply air duct as per sensor manufacturer's recommendations.

[00136] Figure 11. shows the REMOTE SAMPLING TUBE INSTALLATION

[00137] Display [00138] The display module is a 2-line by 8-character LCD. Standard reading in operation is [00139] Keypad and Function Configuration [00140] Relay settings and other configurable items are accessed through the keypad and menu display.

[00141] The keypad is a set of 3 buttons recessed along the upper right side of the enclosure. It is not necessary to open the cover for use of the keypad. Access to the menus is password restricted.
Press any key for 3 seconds to enter the menus. (See below for details) [00142] Password [00143] Factory preset default password is 0017.

[00144] Password can be changed. RECORD PASSWORD IN A SECURE PLACE. If the password is lost, the unit must be returned to QEL to be reset [00145] Output Signals [00146] Options are 4-20 milliamp or 2-10 VDC linear. Choose the option by moving the jumper on JP3. On overrange concentrations the signal can exceed the range slightly.

[00147] IMPORTANT: Voltage monitoring should be into a monitor with at least 50 000 ohms input impedance. Voltage monitoring is not recommended over long distances, as these signals are more susceptible to induced noise than current signals [00148] Signal and Display Range [00149] It is important to distinguish between Signal Range (often called Span) and Display Range.

[00150] Display Range is the range of concentrations the unit is capable of displaying (which is the same concentration it will report on the digital communications). The display range varies with the gas type.

[00151]Signal Range is the assignment of the 4 to 20 milliamp signal. Default assignment of 4 milliamps is zero concentration. The default setting for 20 milliamps varies with the gas type.

[00152] The Signal range is fully adjustable within the limits imposed by the Display Range. Both the 4 mA level and the 20 mA level can be reassigned through the menu system.
Please note that this adjustment does not change the measurement resolution.

[00153] Calibration [00154] The sensor is strongly linear in it's response to gas. It is therefore straight forward to calibrate. Two gases are needed for calibration: Zero gas (clean air) and an appropriate span gas.
Adjustment is by one potentiometer on the circuit board.

[00209] Understanding profile plate burners: (for information only) [00210] The most common Profile plate bumer manufacturers are Maxon and Midco (Figure 19):

[00211]They use the same type of process: profile plates installed in the duct or plenum to concentrates a certain amount of air through the burner assembly. Air stream velocity criteria across and through the bumer's mixing plates must be kept uniform and within the desired limits by use of a silhouette profile plate through which the burner fires:
a. 1- Direction of air A= Min 6"
b. 2- Adjustable profile plate B = Min 6"
c. 3- Fixed profile plate L = Flame length d. 4- Support bracket e. 5- Existing differential pressure switch [00212] As shown above (Figure 20), the fixed and adjustable profile plates play an important role in air gas mix at the burner. The replacement of the adjustable plates by two dampers have the same effect except that the controller is set to maintain the differential pressure at a constant level provided that the pressure reading is made parallel to the differential pressure switch (5).

[00213] AIR-GAS MIXTURE (Figure 21):

[00214] Maxon offers several variations of burners, each optimized for a specific type of application.
All are raw-gas burners, intended for use in fresh air streams.

[00215] For make-up air heating [00216] NP-I and NP-11 AIRFLO burner types provide a nominal capacity of 0.5 MBtu/h per foot .
Turndown of 25 : 1. With staged burner configuration turndown may exceed 50 :
1. Optimum air stream velocity is 3000 ft/min.

[00217] NP-II AIRFLO burners are selected when gas supply pressure is too low for NP-I
AIRFLO burners. NP-II AIRFLO burners will cover the same applications with a turndown of 20 :
1.

[00218] For 2-speed air handling systems [00219] Usually make-up air applications. RG -IV AIRFLO burners (for natural gas only) may be used for a nominal capacity of 0.5 MBtu per foot at an optimum velocity of 3000 ft/min or 0.25 MBtu per foot at a velocity of 1500 ft/min.

[00220] The following Figure (Figure 22) (from Maxon) shows Air pressure differential desired for proper velocity operation:

[00221] Velocity under 2400 fpm and over 3300 fpm are not recommended. This means that the differential pressure across the profiles plates should read between 0.36 and 0.64 in w.c. for Maxon burners.

[00222] For gas emissions efficiency (Figure 23), a setting of 0.57 is preferred to maintain a 3000 fpm velocity. The following table shows the gas emission rate according to velocity readings:

[00223] Natural Gas is supplied to the burner through a gas train which is typically shown on the following figure (Figure 24):

[00224] Control check list [00225] Check Power Voltage (+10%, - 10% of rated voltage) V

[00226] Check control cable installation [00227] Installation environment conforms to the Noveo system specifications for ambient conditions.

[00228] The panel is mounted securely.

[00229] Space around the panel meets the specifications for cooling.

[00230] The motor and driven equipment are ready for start.

[00231]The panel is properly grounded.

[00232] The input power (mains) voltage matches the drive nominal input voltage.

[00233] The input power (mains) connections at L1, L2 and L3 are connected and tightened as specified.

[00234] The input power (mains) fuses are installed.

[00235] The motor connections at T1, T2 and T3 are connected and tightened as specified.

[00236] The motor cable is routed away from other cables.

[00237] NO power factor compensation capacitors are in the motor cable.

[00238] The control connections are connected and tightened as specified.

[00239] NO tools or foreign objects (such as drill shavings) are inside the panel.

[00240] NO alternate power source for the motor (such as a bypass connection) is connected. No voltage is applied to the output of the panel.

[00241] Make-up check list (this list is provided for information only) [00242] Check make-up unit manufacturer's start-up instructions.

[00243] This section must be completed by a qualified gas technician only.

[00244] WARNING : FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.

[00245] Check for gas leaks with rich soap and water solution any time work is done on a gas control.

[00246] Check to be sure that damper opens.

[00247] Make sure that the main firing valve is closed, but that gas is available in the service line.

[00248] Check to ensure exhaust fans are wired into the control panel and that there is power to the exhaust starter relays. Check to ensure exhaust fans interlock switches are installed and wired to the control panel.

[00249] Familiarize yourself with the sequence of operation and wiring diagrams. This will give you information as to how the unit operates.

[00250] Check setting of high limits.
[00251 ] The unit should operate as per sequence of operation.
[00252] Pilot [00253] The Protectorelay monitors the pilot flame through the flame rod. A
minute current is sent from the relay through the flame rod, and trough the pilot flame to "ground".
The relay detects the current flow and acts to open the safety valve as required. When no flame exists, current cannot flow and the relay acts to close the valve. Current flow depends only on flame contact on the rod:
temperature of the rod is of no importance.
[00254] Since the flame rod is a current-carrying conductor, it must be free of any contact with conductive parts of the pilot burner. Insulator must be clean, dry and free from cracks. While the flame rod is made of a heat resistant alloy it may, after long service, deteriorate to the point of flame contact. Check for serious corrosion or loss of metal. It must be tight enough in the insulator to maintain its position. Do not use too much force or the insulator may crack.
[00255] Proper operation of the flame rod can be checked by measuring the flame rod current; refer to flame safeguard instruction sheet with unit. Lacking a micrometer, a check can be made with an operating burner through all its normal phases. Relay response should be prompt with no chattering or drop out.
[00256] The spark rod produces a high tension arc at the correct location for lighting the pilot.
Ignition transformer must be rated for 6000 Volts, 20 Miliampers secondary, minimum.
[00257] The spark rod or spark ignitor, must be free of contact with conductive parts of the pilot burner. Insulator must be clean, dry and free of cracks. Check the spark rod for serious corrosion or loss of metal. It must be held tightly enough in the insulator to maintain its position.
[00258] Gap must be 1/16" to 3/32" . Setting can also be checked by cycling the pilot. Ignition must be prompt and positive. Do not allow careless positioning to cause arc of flame rod; serious relay damage would result.
[00259] If the spark ignitor on Maxon burners shows deterioration of ignitor points the complete spark ignitor should be replaced.
[00260] If pilot tries for ignition, but locks out, the air proving switches (high and low) that are mounted across the profile plate, should be checked to make sure that the proper amount of air is flowing through the unit. Check to make sure blowers are running in the proper direction. This can be checked by placing a differential gauge across the profile plate of the burner section. If the pressure drop is between .30" W.C., and .95" W.C., these switches should be made, then check pilot to ensure proper flame. Check instruction sheet for flame safeguard system.
[00261] Pilot adjustment screw is in the shut-off valve. When setting, adjust for the best reading, then open pilot set screw slightly.
[00262] Main flame supervision: With units that have more than three feet of burner from point or supervision, a second flame rod will be on the main burner. This switching is done with a time delay relay (see wiring diagram). This can be disconnected for testing for pilot, or you have to ensure main flame by opening up the firing valve within 15 seconds after pilot solenoid is powered. As supervision will switch from pilot to main flame in that time. Check to ensure that unit will lock-out in the event of main flame failure on low-fire by closing main firing valve.
[00263] EXHAUST INTERLOCK

[00264] This make-up unit is normally electrically interlocked so that it will operate only when the associated exhaust system(s) is functioning. An exhaust air flow proving switch is normally be used.
With NOVEO MUV product, the interlock is done using DDC control logic.
[00265] The total air discharge capacity of the unit do not exceed by more than 10% the total capacity of the exhaust systems in conjunction with which it is used. Where the tempered air is discharged directly into a booth, the total air discharge capacity of the booth.
[00266] The exhaust air proving interlock should be set as shut-down the make-up unit when the volume of exhaust drops by more than 10%.
[00267] General keyboard information [00268] The different displays shown in Figure 25 are activated by lightly pressing as required on the appropriate touch button. For button selection, check for position on the drawing above. For example, button No2 is located between the two arrows; button No4 is located below UP arrow.

[00271] Initial start-up is shown in Figure 26.
[00272] All levels are factory presets. Nevertheless, the following section will provide extended instructions for adjusting the operating parameters and calibrating the sensors.

[00273] Extended configurations (using Laptop and KMC BacNet interface) [00274] The BAC-5802 are native BACnet, fully programmable, direct digital controllers. Use these versatile general purpose controllers in stand alone environments or networked to other BACnet devices. As part of a complete facilities management system, the BAC-5802 controllers provide precise monitoring and control of connected points, as shown in Figure 27.
[00275] The following features are included:
[00276] Inputs [00277] 8 universal inputs each of which is programmable as an analog, binary or accumulator object. Accumulators limited to three per controller [00278] Pull-up resistors for switch contacts and other unpowered equipment.
Switch select none or [00279] 10 kf2 [00280] 10-bit analog-to-digital conversion [00281] 0-5 volts DC analog input range [00282] Compatible with KMD-1 161 NetSensors.
[00283] Outputs [00284] 8 universal outputs each of which is programmable as an analog or binary object.
[00285] 0-10 volts DC for analog objects [00286] 0-12 volts DC for binary objects [00287] Output current limited to 100 mA per output or [00288] 350 mA total. Outputs are short protected.
[00289] Communications [00290] EIA-485 operating up to 76.8 kb [00291] NetSensor compatible through RJ-1 2 connector Microprocessor-based system operation [00292] The purpose of using a microprocessor-based controller is to interface the Make-up unit operation with an "intelligent" device that will take operating parameters in consideration while modulating the equipment to:
[00293] Control the supply air temperature according to a 10K thermistor discharge sensor [00294] Control the room temperature (optional if sensor is installed) [00295] Command the Make-Up speed variation device (VFD or Clutch Drive) according to building pressure or input from other source [00296] Command the Profile Plates Damper Actuator according to differential pressure readings SEQUENCES OF OPERATION
[00297] FAN OPERATION:
[00298] A table of Noveo-Air Units connected to the network specifies the specified CFM exhaust rate and collects the actual exhaust rate. An exhaust rate greater than 30% of the Make-Up Supply CFM specified rate activates the Make-Up Request. Inlet Dampers opens and remains open until the Make-Up Request drops for more than 30 minutes. Then the dampers shuts.
[00299] Make-Up VFD speed is following a predetermined table (with 10 segments) related to requested CFMs. When requested CFM are lower than 30% of Make-Up max CFM, VFD
is set to 0.

HEATING OPERATION:
[00300] If Outside Air Temperature is lower than AV15, unit is set to Winter mode. Heating is allowed. In summer mode, heating is shutdown.
[00301] Supply air Temperature is controlled according to setpoint within a PI
control strategy. Gas Valve Actuator are not always the same. An adjustable 5 segments slope should be programmable.
[00302] Heating capacity has to be limited according to VFD or CFM supply. An adjustable 5 segment slope should be programmable for this purpose.

PROFILE PLATES DAMPER OPERATION:
[00303] Dampers position is set according to a pressure setpoint (AV5) within a PI control strategy.
A dead zone should be provided to limit dampers actuators movements.

OPERATION
Make-up unit adjustment (for information only) OPERATING PRINCIPLES OF THE RAW GAS BURNER
[00304] The raw gas burner is designed to operate in a duct of flowing fresh air. Fuel gas is fed directly to the burners; kinetic energy of the air stream furnishes combustion air. The burner must be installed to fire with, and parallel to, the air flow. By virtue of velocity impact and suction generated by the diverging shape of the combustion baffles, air is induced into the air ports in the combustion zone. The air supply is constant though only that which mixes with the gas flowing from the burner ports, takes part in combusfion.
[00305] When a very small quantity of gas is admitted to the burner, sufficient mixing takes place in the low fire slot within the burner, casting and combustion takes place in this zone. Since the low fire zone is contained within the bumer casting it is effectively shielded from fire disrupting uncontrolled air entry.
[00306] As the gas is increased the flame progresses into the intermediate fire zone where an additional supply of air is available. High or full capacity, mixing occurs at the larger air ports of the high fire zone augmented by air spilling over the end of the baffles.
[00307] On a reduction of gas supply the reverse sequence takes place. The flame receding to a location of lesser air supply until the low flre zone is reached. The system above is suitable for a turn down range of approximately 25-30 to 1.
[00308] With the suction by the blower there is a pressure in the gas manifold of less that zero at low fire. Therefore, when checking the manifold pressure you will find that the pressure will range from approximately 4" W.C. to less than zero, when the unit is modulating from high to low fire.

EXAMPLE FOR CALCULATING CFM
[00309] Example for calculating the amount of air and gas in a direct fired make-up air unit pull through type [00310] YOU WILL NEED: A pressure differential gauge (Manometer) (Magnehelic) Thermometer -30 F to 200 F.
[00311]AII units are factory set with a profile opening around to burner sized for 3000 F.P.M.
velocity. Due to more or less external static pressure the velocity may not be within this range on start up of unit. The pressure drop should be checked to insure the unit is operating around this velocity.
[00312] An adjustment on the VFD should be done to bring the velocity within operating range. If an air balance has been done and the C.F.M. verified to be correct as stamped on the rating plate and the velocity across the burner is not correct the profile area is adjusted by the controller differential pressure setpoint.

[00313] If velocity is higher than 3000 FPM then the profile area is increased by the damper actuator. The profile area is stamped on the rating plate, but to get to the free area you will have to deduct the space taken up by the burner.
[00314] If Midco burner is used deduct 0.65 sq. feet for each 1-foot section, or 0.33 sq. feet for each 6" section. If Maxon burner is used deduct .45 sq. feet for each 1-foot section, or 0.23 sq. feet for each 6" section.
[00315] Using a Magnehelic differential gauge across the burner profile will give you the pressure drop and using the burner capacity chart will tell you what velocity you have through the profile. If the unit is operating between 0.45 W.C. and 0.65 W.C. it is considered to be within operating range, as the low air switch is factory set to make at 0.25 W.C. and the high profile switch is set to open at 0.95 W.C.
[00316] This should allow for a wide leeway before the unit will lock out due to low air / high air velocity FEATURES

[00327] Under normal servicing the tubes from the air switch should be checked to insure they are free of any moisture or dirt as this could cause the burner to lockout on the flame safeguard relay as both switches are in the flame rod circuit.
[00328] If moisture is entering the tubes they may have to be repositioned to a lower area on the cabinet. Care must be taken to insure that they will operate to shut down the unit if the velocity is out of the operating set points.MUV-R (Remote control panel) Description:

[00421] [REQ 27] Le contr6leur ajuste les volets 6 la P.P. pour un dLsbit d'air maximum lorsque la chauffe est desactiv6e.
[00422] [REQ 28] Le contr6leur ferme les volets lorsque le syst6me est A
I'arret.
[00423] [REQ 29] Le contr6leur ouvre les volets en permanence lorsque le syst6me est en mode summer .
[00424] Note : on ouvre dans le but d'6viter les mouvements inutiles des volets et l'usure des pi6ces.
[00425] Ventilation minimale en fonction des volets [00426] Mise en contexte : Pour que le bruleur puisse fonctionner correctement, un d6bit d'air minimum doit toujours @tre disponible .1 la plaque profil6e. Ce d6bit d'air ne doit jamais descendre au point de provoquer Ia fermeture maximale des volets, puisque le bruleur risque de g6n6rer un exc6s du COV dans cette condition. On doit laisser un jeu minimum sur l'ouverture des volets. Or le d6bit est fonction de Ia temp6rature et par cons6quent cette valeur minimum n'est pas fixe, elle varie selon les saisons, Ia pression du batiment, etc. On parle alors d'une vitesse minimum dynamique (VminDyn).
[00427] [REQ 30] En mode d'ajustement de VminDyn, Vapp peut dtre diff6rente de Vcible et Ie contr6leur ajuste Vapp pour que I'ouverture des volets soit de 6% 2%.

Claims (12)

1. A direct gas-fired make-up air system comprising an inlet and an outlet to transport outside air to the inside (of a building or spray booth) through a duct, said duct comprising a variable speed fan, at least one burner for fuel combustion, at least one probe to measure airflow at said burner, at least one damper controlled by an actuator for airflow adjustment and a controller programmed to adjust said damper and said fan to stabilize airflow at said burner for complete combustion of gas in said burner, said controller being configured to cause said fan to accelerate from a stationary state to an operational speed at a full acceleration rate of said fan, and to cause said burner to begin combustion at said operational speed, whereby start-up time is decreased for burner ignition such that cold air inflow during the startup process is minimized.

2. The system of claim 1 wherein the make-up air unit supplies air to a spray booth.

3. The system of claim 1 wherein a quick startup is achieved by lowering the fan speed threshold at which burner ignition occurs while simultaneously probing for dangerous combustion by-products to ensure safe operating conditions

4. The system of claim 3 wherein the burner is ignited at a fan speed representing 40% of maximal speed.

5. The system of claim 1 wherein the fan acceleration slope dictated by a variable frequency drive is maximal until reaching the minimal threshold required for burner ignition and decreases thereafter to prevent fan speed variations that would otherwise cause said airflow variations to shut off said burner or result in suboptimal combustion.

6. The system of claim 1 wherein said start-up time is minimized by rapidly attaining (through rapid damper actuators and rapid fan speed changes) a set of pre-established values of airflow before burner ignition can occur, at which time more gradual variations can be used to prevent burner shut off or suboptimal combustion.

7. The system of claim 1 wherein said start-up time is minimized by a variable frequency drive which allows for rapid fan speed changes.

8. A direct gas-fired make-up air system comprising an inlet and an outlet to transport outside air to the inside through a duct, said duct comprising a variable speed fan, at least one burner for fuel combustion, at least one probe to measure airflow at said burner and at least one damper for airflow adjustment, said at least one damper controlled by a fast-acting actuator ensuring constant airflow at said burner during rapid fan speed variations that would otherwise cause said pressure differential to shut off said burner or result in suboptimal combustion.

9. The system of claim 8 wherein a fast acting damper actuator allows the slope of fan speed variation after burner ignition to be greater than would be possible without said fast-acting damper actuator.

10. The system of claim 8 wherein the amount of air evacuated is limited by the amount of make-up air entered, thus limiting the potential for negative pressure inside the spray booth.

11. The system of claim 10 wherein an alarm sounds if the make-up air intake cannot compensate the evacuated air.

12. A method to increase the comfort to a spray booth user comprising:
installing the system of claim 1.
