A pioneer in corrugated fin de velopment
HI-F Means High Efficiency
A principal factor governing fin heat transfer efficiency is the boundary layer film of air adhering to any fin surface. This boundary layer insulates the fin, severely reducing the rate of heat exchange. The advanced rippled-corrugated HI-F design creates a state of continuous turbulence which effectively reduces the boundary layer formation. The exclusive rippled edge instantly deflects the incoming air to create initial turbulence. A succession of corrugations across the fin depth, in conjunc­tion with the staggered tubes, increases the turbulating effect and eliminates the "dead spots" behind the tubes. In this manner, the HI-F design establishes a high standard in heat transfer efficiency yielding sharply increased performance. The rippled fin edge also strengthens the fin edge and pro­vides a pleasing overall appearance.
E-F Means Energy Efficient
The term "energy efficient," which is used to describe how well a system utilizes energy, has become a common expres­sion in the HVAC industry. With costs of energy rising, the need for cutting operating expenses is apparent. Lowering the air pressure drop across the face of the coil will reduce the fan brake horsepower requirement and fan motor electrical demand. The need to cut operating energy expenses is met by the E-F fin surface. The smoother fin design of the E-F surface results in lower operating costs over the life of the equipment.

Staggered Tube Design For High Performance
The more moving air in contact with the tubes in the coil, the more performance obtained from the total available surface. The staggered tube design exposes the tubes to more mov­ing air than the in-line design. The geometry of the staggered tube design also allows the rows to be spaced closer together. This results in a more compact coil providing higher capacities.

Coil Selection
General Considerations
The cooling process should always be plotted on a psychro­metric chart to be sure that desired psychrometric changes are feasible. When selecting a coil, it should be remembered that if the required leaving wet bulb temperature is attained, the total load is satisfied and vice versa. Also, when the required leav­ing dry bulb temperature is met, the sensible load require­ment is satisfied. A coil must meet both the total and sensible load requirement in order to achieve the conditions desired in the space to be cooled. Normally, the total load capacity is checked first. However, the leaving dry bulb should always be checked. When the sensible to total load ratio (S/T ratio) is low, the coil selection is normally controlled by the total load even though the sensible cooling capacity may exceed the requirement. In some cases, if the leaving dry bulb temperature is too low, reheat may be required. When the S/T ratio is high, the coil selection is normally con­trolled by the sensible cooling even though the total capacity may exceed that required. If the total capacity far exceeds the requirement, a recheck on the system should be made to be sure sufficient system capacity is available.
HI-F5 versus E-F5
Two different corrugated coil surfaces are offered to provide the most economical coil for a given application.
Normal cooling coil face velocities range from 300 to 700 FPM. For most applications, 500 to 600 FPM is recom­mended. See the individual air pressure drop curves (pages 11 & 14). to determine under what conditions moisture carry­over might be a consideration. Water velocity in the tubes of approximately 3 to 6 FPS is desirable to attain high heat transfer rates with a reasonable water pressure drop. Water velocity above 8 FPS may cause erosion in copper tube coils. Cooling coils should not normally exceed 54" fin height as the condensate draining from the top portion of the coil tends to load up on the lower portion of the coil and a significant reduction in airflow and performance may result. Where the fin height exceeds 54", we recommend two or more coils banked one above the other and installed in accordance with the recommendations shown below. Cooling coils are normally selected to have a finned length of three to four times the fin height for economy. Coils of several different face dimensions are usually available to meet the required face area.

Application recommendations, water cooling coils
1. Piping should be in accordance with accepted industry standards.
2. When drainable coils are desired, tubes should be installed in a horizontal position using a spirit level. If the tubes cannot be installed level, special drain headers are available on request.
3. Coils are unique for either right- or left-hand airflow. The coil hand must be specified. CONNECT THE WATER SUPPLY T O THE CONNECTION ON THE AIR LEAVING SIDE AND THE WATER RETURN TO THE CONNEC­TION ON THE AIR ENTERING SIDE.
4. When cooling coils are banked two or three hi gh, a drain gutter should be installed on the air leaving side of each coil to collect the condensate. On high latent installations, the condensate draining from top coils would load the lower coils with condensate and a reduction in airflow and performance may result. All individually installed water cooling coils and the bottom coils of all cooling coi l banks should be mounted in drain pans extending at least 10 inches from the leaving air edge of the coil.
5. When fresh air and return air are to be cooled by a water coil, care should be exercised in the design of the duct­work to provide thorough mixing before the air enters the
coil. If large quantities of fresh air below 40°F are intro­duced into the system, steam distributing coils should be installed in the fresh air duct or mixing plenum as pre­heaters to raise the air temperature to a minimum of 40°F. This holds true unless the wate r coil is drained and filled with antifreeze. Even though the coil is drained, there may be enough water remaining to cause freeze damage. The coil should be drained and flushed with antifreeze. On any system that has fresh air introduced in the winter season, all possible precaution must be taken to prevent freezing.
6. Control of water cooling coils can be accomplished by two-position control valves, modulating valves, three-way valves, face and bypass dampers, or a combination of these controls. Follow the recommendations of the con­trol manufacturer regarding types, sizing and locations.
7. The pipe size for the system must be selected on the basis of the head (pressure) available from the circulating pump. It is recommended that the velocity should not generally exceed 8 feet per second and that the pressure drop should be approximately 3 feet of water per 100 feet of pipe.

HI-F5 & E-F5 water cooling coils
HI-F5 and E-F5 water cooling coils are designed for use with chilled or well water on comfort cooling, process, dehumidify­ing and special applications. All water cooling coils have vents and drains to aid drainability. 5W Water Cooling Coils are designed for general purpose cooling. All 5W coils have heavy-gauge seamless drawn cop­per tube headers with carbon steel connections. This proven header design can lengthen coil life by providing necessary header flexibility to compensate for normal expansion and contraction during operation. Intermediate drain headers are available for coils that cannot be installed level.
General Formulas
TOTAL BTUH:
Total BTUH = 4.5 X SCFM X (Total Heat Ent. Air ­ Total Heat Lvg. Air)

TOTAL BTUH:
Total BTUH = 500 x GPM x (Lvg. Water Temp. ­ En t. Water Temp.)
Where: 500 = lbs. / gal. x min. / hr. x Specific heat water Lbs. / gal. = 8.33 Min. / hr. = 60 Specific Heat Water = 1
SENSIBLE BTUH:
Sensible BTUH = 1.09 x SCFM x (Ent. Air DB -Lvg. Air DB)
Where: 1.09 = (Specific heat of air at 70° F) x (Min/hr.) x Density Std. Air Specific heat of air = .242 at 70° F Min./hr. = 60 Density Std. Air = .075 lbs. / cu ft.

HI-F5 & E-F5 evaporator coils
Hl-F5 and E-F5 Evaporator coils are designed and engi­neered for efficient operation with either Refrigerant 22, R407C, R410A or 134a. (R407C, R410A and R-134a coils are not ARI certified.) The performance capabilities are excellent for comfort cooling, process refrigeration, and moisture control dehumidifying.
Direct expansion type 5E evaporator coils are engineered and designed to deliver the maximum possible heat transfer efficiency under all operating conditions. The wide variety of circuiting available offers the opportunity to provide the best circuit for peak coil performance. All evaporator coils are counterflow circuited and equipped with pressure type dis­tributors and all refrigerant distributor tubes are of equal length to provide equal distribution of refrigerant to each cir­cuit.
Capacity reduction applications
Interlaced control, 5EJ & 5EK
To achieve energy economy, compressors with capacity reduction capability have become an industry standard. Bal­ancing the evaporator coil capacity to the compressor capac­ity requires the use of face, row or interlaced control coils. To achieve face control, two coils are mounted one above the other and piped to separate refrigerant circuits. A single coil can also be provided with two distributors and two sets of suction connections in a face split configuration.
Row control is achieved by placing one coil in front of the other or by installing a single coil with two separate refriger­ant circuits. The first few rows of coil are circuited together and provided with distributor and suction connections. The balance of the coil rows are provided with a second set of distributor and suction connections.
Interlaced control offers the optimum in capacity reduction. Interlaced coils provide higher part load capability than face or row control coils. The unique interlaced circuiting allows the entire face and depth of the coil to be active under part load conditions. Interlaced coils offer higher part load capac­ity because when only one circuit is active heat transfer is enhanced by additional fin surface that would normally be associated with the other refrigerant circuit.
Face control, 5EF
Many standard 5E evaporator coils with normal circuiting (5EN) are furnished with two distributors and two sets of suc­tion connections. Coils with the number of circuits marked with an asterisk (*) in the circuiting availability table on page 22 are normally furnished suitable for 50% capacity reduc­tion face control.
Face control (5EF) coils are also offered to accommodate 50% capacity reduction face control applications. For circuit­ing availability, refer to page 22.
Interlaced control coils are offered in two configurations, 5EJ and 5EK. 5EJ coils are provided with two distributors and two sets of suction connections. 5EK coils offer a combination interlaced/face split capacity reduction capa­bility. Four separate refrigerant circuits are provided, each with an individual set of distributor and suction connec­tions. Circuiting availability is presented in on page 22.
Example evaporator coil rating
The capacity data tables in this catalog rate a given coil at the ARI conditions. For example, rate the following coil:
Coil model ........................................................... 5EN0804C
Coil size...................................................... ... ... ...........24x48
Entering dry bulb.................. ....................................... ..80°F
Entering wet bulb........................................................... 67°F
Suction temperature......................................................40°F
Airflow.....................................................500 feet per minute
Refrigerant..................................................................... R-22
On page 20, find the table for Hl-F5 5/8" coils, 24x48 inches, with R-22. Follow the 4-row column down until you reach the 8 fpi (8 fins per inch) row. This coil will provide
148.03 mbh with 56.6° F leaving dry bulb temperature and
55.1° F leaving wet bulb temperature. Find the air pressure drop for this coil by following the example on page 11. F or our example coil rating the air pressure drop equals 0.68 inches w.g.
To select an evaporator coil to meet specific performance requirements, contact your local representative.
Row control, 5ER
Coils used for row control cannot always be circuited for the reduction capacities desired because of physical limitations. For this reason, row control capacity reduction is offered as standard for 6-row coils only as indicated on page 22. Six­row coils are split 2 rows and 4 rows which offers approxi­mately 50% reduction per split.

Distributor and suction connection size selection
Distributor, nozzle and suction connection selection is best accomplished by the use of SelectTOOLS
TM
for Contractor Coils selection program. The program output includes coil nomenclature that designates the distributor, nozzle and suction connection sizes. The 3-digit distributor code gives distributor selection information. The first digit designates the distributor tube size, either a 7 for 1/4 inch tubes or 8 for 5/16 inch tubes. The last two digits designate the number of cir­cuits in the coil. The 2-digit nozzle code number gives the nozzle size required for the distributor and is also used to determine the suction connection size for the coil. Examples are listed in Table 5. Suction connections sizes for the vari­ous evaporator coil types are listed in Table 6. Evaporator coil circuiting availability is presented in Tables 7A and 7B. Liquid line (distributor) sizes are presented in Table 8.

Conv ersion of air volume to standard air
When the specified air volume (CFM) is given at any temperature other than 70° F or any altitude other than sea level, these charts should be used for correction before using the capacity and pres­sure drop tables which are based on CFM at standard air conditions.
EXAMPLE:
To convert 15,900 CFM of air at 95°F and at 3,000 feet altitude to standard conditions:
CFM of Standard Air = (CF M of Specified Air x F
x F
T
A
= 15,900 x 0.955 x 0.896 = 13.600
Where:
= Temperature Conversion Factor
F
T
F
= Altitude Conversion Factor
A
The CFM of standard air should be used to determine face velocity through the coil, which in turn is used to determine heat transfer val­ues, and the air pressure drop through the coil. The air pressure drop value taken from Figures 1 and 2 must be con­verted to altitude to be used for static pressure calculations. To con­vert the air pressure drop from stan­dard air at sea level to the air pressure drop at altitude use the following equation:
Pressure Drop = Pressure Drop at Sea Level at Altitude FT x F

Engineering guide specifications
Furnish and install as shown on the plans and as described in the tabulated specifications, McQuay ARI certified water cooling coils 5W or evaporator coils 5E. The coil shall be of extended surface, staggered tube, rippled plate fin type. Coil performance shall be substantiated by computer generated output data.
PRIMARY SURFACE: The primary surface shall be round seamless (5/8“ O.D.) copper tube on 1-1/2” centers, staggered in the direction of airflow. All joints shall be brazed.
SECONDARY SURFACE: The secondary surface shall consist of rippled aluminum plate fins for higher capacity and struc­tural strength. Fins shall have full drawn collars to provide a continuous surface cover over the entire tube for maximum heat transfer. Bare copper tube shall not be visible between fins. Tubes shall be mechanically expanded into the fins to provide a continuous primary to secondary compression bond over the entire finned length for maximum heat transfer rates.
CASINGS: Casings shall be constructed of continuous galvanized steel with 3/8” diameter bolt holes for mounting on 6” cen­ters. Coil side plates shall be of reinforced flange type.
COILS: Coils shall have the connections located to permit (unique) (universal) mounting of the coil for right- or left-hand airflow and have equal pressure drop through all circuits. Coils shall be circuited for counterflow heat transfer to provide the maximum mean effective temperature difference for maximum heat transfer rates. All coils over 45” FL shall be furnished with 4 fin angles to properly position the coil core.
WATER COILS: Headers on water coils shall be seamless copper tubing. The headers shall have intruded tube holes to pro­vide large brazing surface for maximum strength and inherent flexibility. The complete 5W coil core shall be tested with 315 pounds air pressure under warm water and be suitable for operation at 250 psig working pressures. Individual tube test and core tests before installation of headers is not considered satisfactory. Hydro­static tests alone will not be acceptable. Water cooling coils shall be circuited for drainability and for service without removing individual plugs from each tube.
EVAPORATOR COILS: Evaporator coils shall be tested with 315 pounds air pressure under warm water, and be suitable for 250 psig working pressure. Coils hydrostatically tested will not be permitted. Coils shall be ARI certified and Underwriters’ Lab­oratories recognized. All coils shall be circuited in a counterflow manner with uniform circuits.
BRASS LIQUID DISTRIBUTORS: Distributors factory mounted of the pressure type, will be furnished. Loading per circuit must be such that the refrigerant pressure drop is within reasonable limits to prevent loss of coil capacity.
EVAPORATOR CAPACITIES: Capacities shall be as outlined in the tabulation with _____°F suction temperature for refrigerant R_____
