Benefits

Evaporating from the surface of an indoor swimming pool causes two major concerns. The first and most obvious problem relates to the resulting high relative humidity level.

During periods of low outside air temperatures, high indoor humidity causes problems with condensation and frost on windows.

A more serious problem could result if moisture penetrates into the building structure, where it could condense and freeze thereby causing structure damage.

The second major concern is heat loss from the surface of the swimming pool. As moisture evaporates from the surface of the pool, a large amount of heat is lost as the latent heat of evaporating is carried away by the moisture. If the humid air was simply exhausted, all of this latent heat would be lost and would have to be replaced by heating the pool water.

This discussion makes the benefits of an Engineered Air PD Series pool de-humidifier obvious. These benefits can be summarized as follows:

1. Reduced pool heating costs due to reclamation of latent heat of evaporating from pool surface.
2. Reduced space humidity levels prevents possible structural damage due to condensation.
3. Space comfort conditions are also obviously improved by the lower relative humidity level. If a remote (outdoor) air-cooled condenser is used, the resulting space cooling ability also has obvious benefits.

Application

A common problem encountered in skating or curling rinks is fog and / or moisture condensing and dripping from the structure. This occurs during periods when the space temperature is low and moisture content of the air relatively high. Condensation problems can occur throughout the year but more frequently occur during the spring and fall seasons.

In pool environments, outside air can often be used to condition the space and reduce the moisture level. This approach cannot be used in a rink environment because the outdoor air contains moisture with a higher dewpoint level than the indoor temperature of the rink. As a result, bringing in outdoor air for ventilation only adds to the fog and condensation problems.

The solution is to remove moisture from the ice rink air by using an Engineered Air dehumidifier. Our CD Series is one option. One alternative is the DWD Desiccant Gas Fired De-humidifier by Engineered Air.

Fundamentals of Operation

• The Engineered Air HE/DWD Series gas fired desiccant dehumidifier uses vapor pressure differential to absorb moisture on the relatively cool process air side and then drive this moisture off in the hot regeneration airstream. The process air is hence dehumidified.
• The desiccant wheel rotates constantly through the process air and the regeneration airstreams.
• The ambient regeneration air is heated by an Engineered Air direct fired burner (HE Series). The water molecules transferred from the process air are then discharged to the ambient.

Benefits

• Gas fired dehumidification units do not have a DX coil and inherent freezing problems associated with a low temperature DX coil. With mechanical cooling dehumidification, the condensed moisture will freeze on the surface of the evaporating coil when the coil surface is below 32°F as is sometimes necessary to reach low dewpoint levels. As a result, the minimum achievable dewpoint is limited by frosting on the DX coil.
• Lower operating cost — especially in areas where the electricity cost is high and the natural gas cost is low. Mechanical cooling compressors require a significant amount of electricity to provide dehumidification.
• No water condensation issues — the mechanical cooling dehumidification evaporator will condense water which will promote undesired microbial growth in the system/
• Lower maintenance cost — gas fired desiccant dehumidifier has fewer components to service than mechanical cooling dehumidification units.

Options

• Mixing boxes can be provided if required.
• Auxiliary Engineered Air cooling components (FW mechanical cooling or chilled water coil) can be added to re-cool dehumidified process air to neutral condition.
• A sensible heat wheel can be added to re-cool the process air down stream of desiccant wheel and preheat the regeneration air upstream of Engineered Air's burner.
• High temperature process exhaust heat (approximately 125°F to 280°F) from the building, steam or electric heat, if available, can be used in the regeneration air to reduce the required heating capacity or eliminate the direct fired burner.
• A cooling coil (DX or chilled water) could be used as an option to re-cool the warm dehumidified air.

The Practical Heat Exchanger for Industrial Heat Recovery

Although industrial process exhaust contains valuable thermal energy, it generally contains contaminants in the form of condensables, corrosives or particulates. These complicate energy recovery efforts.

An effective heat exchanger must be able to separate the BTUs from the dirty air. This requires both a versatile heat exchanger design plus the engineering know-how and experience to properly apply it. Engineered Air, with its HRP Series of Packaged Heat Recovery units, offers you both.

The HRP Series is an air-to-air heat pipe heat exchanger specifically designed for the complexities of industrial heat recovery.

It has the following advantages:

No moving parts

Nothing to wear out, so the HRP Series has an extremely long lifetime with no mechanical maintenance.

No cross
contamination

Sealed partition separates the two airflows preventing contamination of the fresh air by the exhaust.

Self-contained

Requires no external power of operation.

Minimum cleaning

Specially designed with fewer fins on the dirty process exhaust side than on the clean fresh air side. Industrial HRP Series have flat, continuous plate fins to provide see-thru, clean-thru™ capability. Built-up dirt can easily be flushed during cleaning.

Size flexibility

A wide range of sizes are available that can be installed singly or as modules to meet the requirements of almost any airflow system.

Performance
flexibility

A wide range in the number of rows of heat pipes are available to provide desired recovery performance while still affording minimum cleaning maintenance. Buy only the amount of recovery you need.

Material flexibility

Available in different materials of construction to accommodate various corrosive effluents. Heresite® protective coating is also available for temperatures up to 400°F

Compact

HRP Series range from 6 to 16 inches deep in the direction of flow which reduces space required, lowers installation costs, provides ease of handling and simplifies cleaning.

Structurally sound

Constructed of heavy gauge materials to easily withstand the rigors of industrial environments.

In short, the Industrial HRP Series has the versatility needed to meet the varied conditions of industrial heat recovery. In addition, Engineered Air has the knowledge and experience to successfully apply this versatility to solve your heat recovery problems.

Where should HRG Series be used?

1. Commercial and industrial buildings, where exhaust and makeup are required for many hours of the year, the more hours the better.
2. In installations where exhaust air temperatures are from 80°F to 200°F and where the air is not particularly corrosive. Exhaust air temperatures below 80°F tend not to be an economic source of heat, particularly where outdoor air temperatures are sub zero, and the possibility of circulating glycol at temperatures below 32°F exists, thus creating certain frosting conditions on the exhaust coil, which is a dehumidifying coil. While the control system can automatically prevent frost from forming, the efficiency of the system is low while operating in a "frost prevention" mode and energy savings may be less than anticipated.
3. Areas of the country where the normal energy source is relatively expensive will be attractive for heat reclaim systems: the relative cost of energy seems to be rising at an alarming rate throughout all of Canada, so few areas will not find the reclaim of heat a wise economic move.

Why a HRG Series System instead of an Air to Air System?

The reclaim of heat, as developed so far, while saving heating energy, does demand the expenditure of energy in another form; fan motor horsepower to overcome the reclaim device air pressure drop. A glycol run around system requires about the same amount of extra energy to run the two fans and one pump, than an air to air system does for its two fans. However, in the glycol system, the pump may be shut off at a point when it is determined that heating savings no longer outweigh the cost for pump power.

Description

HERESITE is the registered trademark for pure phenol-formaldehyde thermosetting resinous coatings.

The HERESITE coating applied to finned tube coils is the P-413 Flexible Brown Baking Phenolic Coating. This coating is applied to either aluminum, copper or steel with equal results.

We feel it is important to emphasize that HERESITE baking phenolic coatings are manufactured and sold only by HERESITE PROTECTIVE COATINGS INC. Further, the application of the HERESITE baking phenolic coating to finned tube coils is performed at the HERESITE plant in Manitowoc, Wisconsin, USA, at Engineered Air in Calgary, Alberta, Canada and at other authorized facilities.

Advantages

Practically all typed of finned tube coils used for oil, water, air, gas and process cooling (and heating) as well as a large condensing coils can be HERESITE protected against damaging environments. Currently, the HERESITE coating of air-conditioning and industrial process coils exposed to corrosive fumes and salt atmosphere is in the increase, with many new applications being found.

HERESITE coating offers a more economical solution that special metals for these applications. Typically, aluminum fin coil coated with HERESITE are more economical than copper fin coils. Special metal casing materials are unnecessary since the HERESITE coating is applied to the casing as well as to the finned tubes. Additionally, HERESITE coated aluminum fins will resist attack from most cleaning agents more successfully than copper fin coils.

Application

The present day HERESITE coating of finned tube coils is the result of many years experience during which time application equipment and procedures have been constantly improved. Today, Engineered Air has one of the largest HERESITE facilities in the world. The enables us to HERESITE coat, on a routine basis, coils up to the following size and weight:

Maximum Fin Dimensions

240” long × 78” wide × 18” deep

Maximum Weight Per Coil

4,000 pounds per coil

Fin Spacing, 1 to 3 tube rows

16 per inch maximum

Fin Spacing, 4 to 6 tube rows

14 per inch maximum

Fin Spacing, 7 and 8 tube rows

12 per inch maximum

The HERESITE coating of finned tube coils is accomplished by a multiple coat application of dipping and baking resulting in complete coating coverage of the fins, tubes, headers, casings, etc. Consequently, protection against corrosion is provided for the entire coil. Due to specialized surface preparation techniques plus the good adhesive properties of the HERESITE P-413 coating, it is possible to efficiently HERESITE coat all the usual metals used in fabricating finned tube coils.

Benefits

Expandability
Allows the system to grow with the cooling load. Modules can be added at a future date without doing any piping work.

Better Capacity Control Each individual circuit is operating at its optimum efficiency point, providing a high operating efficiency even though the overall assembly is operating at partial load.

Installation
Units are connected to the header using isolation valves and flex joints, meaning they can be mounted directly onto a concrete slab. Header sections are identical to one another. They can be pre-shipped ahead of the chillers, allowing the building piping system to be pre-built.

Flexible Installation Arrangements
The external common header means that modules can be located in different parts of the room or even in separate rooms. As long as the piping is connected so that the master controller measures the system fluid temperature, the system will work effectively.

Service While Under Full Operation
Designed to allow service to all the liquid line components on any of the chillers while the system is under operation.

Redundancy
Add one more module to the system for an "N + 1" capacity so that the overall cooling system capacity is not affected when a module is taken out for regular service or needs repair. Each unit has two independent circuits. If one is lost, only that circuit is affected while all others remain operational. Each module has a fully functioning dedicated logic controller. If communication is lost with the master controller, the individual controllers will automatically take over control of each module. By presetting and staging the set points on all the local controllers, they will then control the system.

Front Serviceability
Set up so that it is front serviceable making it easy to access components requiring routine maintenance.
