How To Become An HVAC Engineer

Today when you solicit any contracting company or developer form Douglas Park to Sleepy Hollow Chicago, about a affordable Electrical Engineering in Chicago, the most popular answer is contact New York Engineers. What’s very well known is that NY-Engineers.Com is probably your best option for anyone looking for a fire protection engineer in Rosehill Chicago. At NY Engineers our crew has many years of experience designing fire protection and sprinkler systems from Oceanside to Kingston, New York. Today, from our Chicago office we are helping general contractor and developers in Rosehill Chicago design the fire protection and sprinkler systems they seek.

The danger of a building burnt down as a consequence of fire is really a sight that no one wants to experience. That is why fire protection engineers are hired before a building or apartment is created. In case you are wondering who needs fire protection engineer, then a first name that you ought to know is definitely the architect from the building. Much like an architect is very important to ensure that the design of your building is ideal and resistant to all ends; a fire protection engineer makes certain that the construction remains safe and secure from possible chances of fire.

Having fast reaction in the firefighting professionals is acceptable but won’t it be better if a fire never happened? You should think about “what if” instead of experiencing the dreadful experience of the building being on fire. Fire protection engineers go through the model of the property first then plan the escape routes to be taken in a fire. In addition to this, they are accountable for connecting several fire protection items in and outside the building. Water hosepipes attached to the main water supply, and checking the fitness of the fire extinguishers are some of the duties the fire protection engineer carries out when they are hired.

Distinction Between Rosehill Chicago Fire Protection Engineers vs Tech

The Society of Fire Protection Engineers features a specific concept of Fire Technology versus Protection Engineers. The two positions call for a solid education in fire technology and experience being a firefighter in most cases.

The engineers use principles to utilize methods and systems setups in different buildings that really help protect individuals and things from injury during fires. Engineers study where the biggest fire risks lie and where to install protection like sprinklers. They make certain that the utilization of buildings and any materials within them are created to keep dangers to a minimum.

Engineers will likely oversee the connection and maintenance of smoke detectors, alarms systems, and will carry out investigations of fires after it happens. This helps them prevent such things from occurring down the road.

This particular rank uses scientific principles to help you enhance the safety of folks in homes and offices. A fire technician operates to conduct the testing and upkeep of the systems that have been arranged and organized by the engineers.

These folks should also possess the correct education and firefighting knowledge to work within the field. They can work to assist add sprinklers and fire alarm systems however they do not plan the design of these systems like the engineers do. There is only so much you can save this page if you would like more information on fire sprinkler system engineering services in Rosehill Chicago by NY Engineers we invite you to take a look at our blog.

Mechanical Engineering Design Options to Heat and Cool Residential Buildings

Value Engineering Examples In Construction

There is a broad range of mechanical engineering and design options available for meeting the heating and cooling needs of residential buildings. Normally, these systems differ in terms of the medium used to deliver their heating or cooling output.

  • Water Piping: Water source heat pumps, radiators using chillers, cooling towers, and boilers.
  • Air Ducts: Packaged rooftop units, packaged ceiling hung units
  • Refrigerant Lines: Split AC systems, VRF systems
  • Direct: Used by window-type air conditioners and PTAC units, which operatedirectly between indoor and outdoor locations, without ducts.

This article will provide an overview of some of the most common mechanical design options used for indoor residential spaces, as well as the strengths and limitations of each type of system:

Detailing Mechanical Engineering and Design Options

Mechanical Design Option #1: Four-Pipe System with Chiller, Cooling Tower, and Boiler

This mechanical design gets its name from the fact that it has two separate water circuits, one carrying hot water and another carrying chilled water, each with a supply and return pipe. The basic operating principle of four-pipe systems is the following:

  • Cooling is accomplished by a chiller and cooling tower: A chilled water circuit is used to remove heat from indoor spaces, and the cooling tower is used to reject it outdoors. If the chiller’s compressor comes equipped with a variable-speed drive, this system can offer a very high efficiency in cooling mode.
  • Heating efficiency is determined by the type of boiler. In general, gas-fired boilerstend to be more cost-effective than those running on oil or electrical resistance heating.
  • Fan-coil units are equipped with both hot and cold water coils, granting them the flexibility of either mode of operation.

The main advantage of four-pipe systems is their ability to use both modes of operation simultaneously and independently. This can be especially useful if heating and cooling needs are different across building zones, and especially in apartment buildings and multi-family dwellings where preferences and schedules normally vary by occupant. Of course, a four-pipe system is an expensive mechanical engineering system to install due to the presence of three separate water circuits: two for the distribution of cold and hot water, and a third one used by the chiller to reject heat through the cooling tower.

Mechanical Design Option #2: Water-Source Heat Pumps with Cooling Tower and Boiler

A heat pump can be described in simple terms as a reversible air conditioner: it can deliver indoor cooling through the refrigeration cycle, but can also operate in heating mode with a much higher efficiency than most types of boilers, especially electrical resistance boilers.

Due to their reversible operation, water-source heat pumps offer great flexibility in residential buildings. Individual units can be set to operate in different modes, and in combined heating and cooling applications the overall system can be extremely efficient:

  • Heat pumps in cooling mode extract heat from indoor spaces and release it into a common water circuit.
  • Then, heat pumps in heating mode can extract the heat now carried by the water, and release it indoors, as required.

The fact that heat pumps share the same water circuit means that the cooling tower and boiler only have to balance system loads, rather than meeting them fully:

  • If the cooling load is greater than the heating load, the cooling tower only has to reject the heat difference, not the total heat removed from all spaces.
  • The same logic applies if the heating load is higher than the cooling load: the boiler only has to make up for the difference, not the full heating load.
  • If the heating and cooling loads happen to balance each other out, both the cooling tower and boiler can remain off.

A four-pipe system lacks these capabilities: the chiller must assume the full cooling load while the boiler provides the full heating load – all the heat absorbed in the chilled water loop is rejected by the cooling tower, and can’t be used for space heating purposes because water circuits are independent.

HVAC systems based on water-source heat pumps are extremely efficient, although expensive due to the fact that every zone must be equipped with an individual heat pump, in addition to having a common water circuit, a cooling tower, and a boiler.

Mechanical Design Option #3: VRF System with Rooftop Condensers & Gas Boiler

VRF stands for variable refrigerant flow, and VRF systems get their name from the fact that refrigerant is used to transport heat instead of water:

  • One or more remotely located condensers provide a flow of refrigerant for multiple indoor fan-coils, and a variable speed drive is used to regulate flow according to load. The units can also provide their own heating.
  • For supplementary heating, a gas-fired boiler with perimeter radiation can be added to the system.
  • Two-pipe VRF systems require all fan-coils to operate in the same mode, but with three-pipe systems, it is possible to provide simultaneous heating and cooling for different areas of the building.

Other than operational flexibility, an advantage of this mechanical design option is their ease of installation: refrigerant lines are more compact than water piping and air ducts. These systems still have a relatively small market share in the USA, but are very common in Japan, where they were developed, and Europe. According to ASHRAE, VRF systems tend to have a comparable cost to that of chiller-based systems, potentially higher if the technology must be imported.

The modular nature of VRF systems is another strong point in favor of this technology. If there will be a building expansion, it is possible to expand the system by simply adding a new condenser and the corresponding indoor evaporators.

Mechanical Design Option #4: PTAC Units with Electric Resistance Heating

Packaged terminal air conditioning units (PTAC) are compact systems, very similar to old window-type air conditioners: the system is self-contained and does not require refrigerant lines, water piping, or air ducts, greatly reducing the installed cost. Some PTAC units are equipped with a resistance heater, allowing them to operate in both heating and cooling modes.

PTAC units offer the advantage of being self-contained and independent from each other. This gives them an advantage in projects that will be built in several stages, for example, apartment buildings, since it is possible to expand HVAC capacity as needed without having a common system on which all units depend.

The main limitation of this mechanical system is that they tend to be outclassed by other systems in terms of efficiency, especially when in heating mode. Resistance heating offers a coefficient of performance of 1.0, which means they must draw one watt of electricity per each watt of heating; on the other hand, heat pumps typically operate with a COP of 2.5 or more, or even above 4.0 if a high-efficiency heat pump is selected.

Concluding Remarks

There is a broad range of heating and cooling technologies available for residential buildings, and also a high degree of flexibility in how the overall system can be configured. No system can be considered superior to the rest under all circumstances – every project offers unique conditions that favor some technologies over others.
