Since 2011 the majority of developers throughout Coram, NY already know that New York Engineers is the engineering firm to call when you are searching for Construction Engineering in NY. What many local property owners have not realized is the NY Engineers is also your best choice if you are looking for HVAC Engineering services in McKinley Park Chicago, IL. Those who need to understand more about what McKinley Park Chicago HVAC design engineers do? This really is a unique trade which has an extensive list of responsibilities. An HVAC design engineer will have to work through several concundrums to work out the original issue. This task requires distinct expertise, proficieny, and the capability to deal with time wisely.

Once an HVAC engineer is licensed to work, they are going to get employed by an engineering company and begin to functions on various heating, cooling, and refrigeration systems. Their task would be to create new and alternative options in line with their customer’s requests. Every client is going to have an exclusive set of wants whether it concerns constructing codes or individual performance prospects. Making use of this information, the engineer sets off on a trek towards making something that is energy-efficient, eco-friendly and ideal for the location it might be placed in – (residential/industrial/commercial). They are often responsible for the initial drafts and overseeing the specific installation.

Generally speaking, an HVAC engineer in McKinley Park Chicago will be seen working with a design business or even in a consulting firm based on their years of skill. Many engineers switch into a consulting job while they grow older and obtain a better knowledge of what’s required of them.

Comparing HVAC Engineer Versus HVAC Technician

HVAC Engineer and HVAC Technician are frequently mistaken for each other. Yet, they may have separate job functions in relation to working with HVAC systems. It’s vital that you understand the contrast both as a customer also as an expert

An HVAC technician in McKinley Park Chicago has a more direct job, meaning they are often seen visiting a owner’s building to deal with their present system. They generally take care of the installations, repairs, and over-all care that is needed every once in awhile. Almost all of their jobs are done alongside the client, meaning they need to understand how to connect to people properly.

By having an HVAC engineer, they are responsible for designing a whole new HVAC system and making sure it meets exactly what a client needs. It has to fit exactly what the property owner wants whether or not this has to do with their setup, property, or everything related to new system. Also, they are brought in to refer to HVAC designs to be certain all things are consistent with the latest standards. For this reason they may find themselves spending some time in consulting tasks or at local engineering companies. This is the distinction between those two occupation; HVAC Technician vs HVAC Engineer.

Construction Engineers Explain How HVAC Systems Move Heat

Value Engineering Examples

Heat movement is required for both space heating and air conditioning. Space heating systems deliver heat and air conditioning systems remove it, but the goal in both cases is reaching a suitable indoor temperature. Construction engineers can explain how, though heat can be transmitted across empty space by radiation, using convection and the bulk movement of a fluid is much more effective. In HVAC applications, the most common fluids used to carry heat are air, water, refrigerants, and steam.

Since each substance has different properties, the heat distribution fluid used by an HVAC system determines many performance features. Also consider that different fluid may be used in the same system, with intermediate heat exchange steps.

Heat Distribution with Air

The main advantage of using air to carry heat is simplicity: air is already present in the atmosphere and indoor spaces, so there is no need to use additional fluids in the HVAC system.  Air can interact directly with AC compressors, furnaces or heat pumps to adjust its temperature, and it can then be distributed using fans and ductwork.

However, air ducts require more space than the piping used by other heat-carrying fluids, and they are impractical when air must travel long vertical distances. Consider that warm air rises while cool air tends to fall below, and fan power increases dramatically if you need to move air against its natural behavior. This is neither practical nor energy efficient!

When air ducts must serve separate zones, its distribution is typically controlled with air dampers. These can adjust their position between fully open and fully closed as needed to regulate airflow, and they are controlled automatically by the thermostats in each zone.

One of the most promising system upgrades for air distribution systems promoted by construction engineers is adding variable frequency drives (VFD) to the fans. Reducing fan speed is much more efficient than intermittent operation when you don’t need the full rated airflow. In the case of fractional horsepower fans, a brushless DC motor is recommended instead of a VFD, since they come with built-in speed control.

Packaged rooftop units are an example of an HVAC system that uses air as the main heat distribution and heat removal medium.

Heat Distribution with Water

Some HVAC systems heat or cool water instead of air, and water then interacts with indoor air through fan coils. When this configuration is used, the installation is referred to as a hydronic system. Compared with air, water can hold much more heat per unit of volume, thanks to its higher specific heat and density. As a result, it is the preferred heat-carrying medium in large commercial and industrial installations: hydronic piping uses much less space than air ducts for a given heating or cooling load.

Just like airflow can be controlled with dampers and VFD-equipped fans, the flow of water in a hydronic system can be controlled with valves and VFD-equipped pumps. The basic principle is the same: finding an operating point where each zone is kept at the required temperature and humidity, at the lowest energy cost possible.

Chillers and boilers are two examples of HVAC systems that rely on water to carry heat. Indoor air can then be heated or cooled using fan-coils. Another possible configuration is using larger air-handling units (AHU) connected to an air duct system, where heat exchange occurs between the hydronic piping and the air being circulated by the AHU.

Refrigerant

All air conditioning compressors and heat pumps use refrigerant internally, but there also HVAC systems with longer refrigerant lines connecting different pieces of equipment. Refrigerant lines are even more compact than hydronic piping, not to mention air ducts. Just like when water is used to carry heat, refrigerant flow can be controlled with the combination of valves and variable speed control for the compressor.

Ductless air conditioners and heat pumps use refrigerant lines between the condenser and evaporator units, and typically offer a very high efficiency. The concept can also be applied for multiple zones served by a single outdoor unit, using a variable refrigerant flow system (VRF). VRF systems are very efficient as well, while consolidating heating and cooling systems into a single installation.

Steam

Many buildings in New York City use steam as a heat-carrying fluid, since a significant portion of the city gets steam as a utility service from Con Edison. However, if you plan to install your own boiler, a hot water system is preferred over a steam system.

The main drawback of steam is that you can use it only for heating in most cases. The only way to achieve cooling with steam through an absorption chiller, but a conventional electric chiller is much more economic in multifamily and commercial settings. Absorption chillers are better suited for applications where heat is available at a very low cost or as a waste product of industrial activity – not when you are paying for steam as utility service.

Since steam cannot be used directly for cooling, buildings with steam radiators often have window-type or through-the-wall air conditioning units. These normally suffer from poor efficiency, so you can consider upgrading to ductless units while the heating system is retrofitted to use hot water.

Our Construction Engineers’ Conclusion

HVAC systems are characterized by their variety, and each configuration brings a different set of performance features. Working with qualified HVAC consultants and construction engineers is recommended to identify the system configuration that works best, according to the specific needs of your building. Also keep in mind that only a registered design professional can submit HVAC designs for approval by the NYC Department of Buildings.
