Recently Many individuals have been taking a look at our website searching for Mechanical Engineering in or near Chicago. This is due primarily due to the reputation we have built in this kind of work. Nevertheless, many building owners from Hickory Hills to Champaign, are not aware that New York Engineers is also the ideal choice for anyone in search of HVAC Chicago, IL.

The quest for energy efficient buildings involves energy-efficient HVAC system design. This may include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for the HVAC systems may come primarily from 5 different bases including lighting (cooling), your building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a function of either the machines needed in an attempt to introduce it in to a space and control contaminant concentration or the number of folks who will fill the room. In virtually all climates inside the southwestern and eastern areas of america, to reduce outter ventilation can save energy whenever the

outside air is either warm and humid or very cold.
Manipulating the ventilation rate will likely be determined by occupancy which is called a kind of demand control ventilation. This really is a common type of energy conservation plan that is used for rooms with irregular or heavy occupancy. Having heating and cooling loads dropped to a minimum can be achieved through the use of a higher performance building envelope, occupancy sensors, and high performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

When you have ever thought about the distinction between a HVAC Technician vs HVAC Engineers, then continue reading:

Chicago HVAC engineers would be the individuals who run the installation of air-con systems both for commercial and residential buildings. They spend lots of their work in offices doing higher level management and arranging of installations however they do also see job sites every now and then.

In contrast, HVAC technicians often do more of the hands-on work with maintenance and repair. A HVAC technician may work with or for an engineer to do a few of the installation task, specifically on smaller jobs. In general HVAC technicians do considerably more travel and may even spend lots of time changing filters, identifying leaks, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers might have a chance to make more decisions about systems that are employed, and they also are definitely the people that would offer assistance with probably the most sensible refrigerants and which systems would be perfect for a much bigger building. In the industry, there is some challenge between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs require an excellent understanding of how air cooling does work. In recent times many Internet users have been reading the NY-Engineers.Com website searching for things like HVAC Contractors Chicago. Nevertheless, the focus of our company is to become the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Electrical Engineering Engineering services. We ask that anyone searching for more info about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois stops by at our blog.

What MEP Engineers Want you to Know About Types of Electric Heat Pumps and Their Advantages

Architecture Engineering Subjects

Before designing the space heating and domestic hot water systems of a building, a key step for MEP engineers is to determine the energy source to run these appliances. Natural gas or fuel oil combustion comes with a lower operating cost than electric resistance heating, but these fuels produce emissions and require an exhaust system. On the other hand, electric heaters have the potential to be emissions-free if they run with solar or wind power.

Resistance heaters are the most common configuration that runs with electricity, but their operating cost can be extremely high considering the electric tariffs in some cities. However, electric heat pumps can normally deliver from 2 to 4 units of heat per unit of electricity consumed, offering a much lower running cost than an equivalent resistance heater. For a given amount of energy delivered, electricity is much more expensive than gas in some areas, but electric heat pumps can match the running cost of gas boilers by using the energy input more efficiently.

This article will provide an overview of the two main electric heat pump configurations: air-source and geothermal systems.

Air-Source Heat Pumps

As implied by their name, air-source heat pumps extract energy from the surrounding air to deliver heat. This is exactly like an air conditioner running in reverse: have you noticed how the outdoor unit makes the air around it warm? Well, a heat pump uses this same effect indoors.

Assuming the same heating capacity, an air-source heat pump with an ENERGY STAR label only draws around 40% of the power required by an electric resistance heater. Their efficiency is indicated by the Heating Seasonal Performance Factor (HSPF), which is a ratio of Btu output to watt-hour input, similar to the gas mileage value of a car. MEP engineers look for the highest HSPF value that fits your budget to maximize energy savings.

Just like air-conditioning systems, air-source heat pumps are available as packaged systems or split systems (ductless). If your property already has ductwork, a packaged heat pump may be best choice. On the other hand, if duct installation is impractical, a ductless system is recommended. ENERGY STAR air-source heat pumps have a minimum HSPF of 8.2 in packaged configuration, and 8.5 in ductless configuration.

Reverse-cycle chillers are a subtype of air-source heat pump that delivers heat to a water reservoir, instead of supplying it directly to indoor air. This setup allows the heat pump to be used with radiant floor heating piping or with fan-coils.

Geothermal Heat Pumps

The temperature of outdoor air varies considerably throughout the year, and air-source heat pumps suffer from reduced efficiency during the coldest days of winter. The ground is much more reliable as source of heat; this system configuration extracts heat directly from the ground, from groundwater, or from a nearby body of water such as a pond or lake. Geothermal heat pump systems are often called water-source heat pumps, since most system configurations use water with antifreeze as a heat exchange medium between the heat pump and the ground.

Geothermal heat pumps offer a higher efficiency than air-source heat pumps. High-efficiency models in the market deliver savings of over 70% compared with electric resistance heaters, and the most efficient geothermal heat pumps in the market save over 80%.

Geothermal heat pumps can be further classified into closed-loop and open-loop systems.

  • Closed-loop systems have a closed piping loop that circulates between the heat pump and the ground, but the water inside never mixes with groundwater.
  • Open-loop systems draw groundwater from a well, circulate it through the heat pump, and then discharge it. Given their operating procedure, open-loop systems are subject to any applicable groundwater discharge regulations.

Closed-loop systems can use either vertical or horizontal water loops, depending on the availability of land. Horizontal loops require trenches at least four feet deep and are suitable in properties with ample land area. On the other hand, vertical loops can go hundreds of feet underground, and are typically used when land is limited – high-rise construction is an example. If the property is close to a body of water such as a pond or lake, the underground water loop can be submerged instead, which results in a much cheaper installation.

MEP Engineers Offer Recommendations to Use Heat Pumps Effectively

If you are considering heat pumps for your building, the best option changes depending on project conditions. Geothermal heat pumps are the most efficient but also the most difficult to install, especially if we’re dealing with a vertical closed-loop system in a high-rise building. Also, consider that geothermal heat pumps require a prior assessment of the ground below your property – the project may be infeasible if the presence of rocks hinders excavation.

Consider a reverse-cycle chiller (RCC) if your installation already uses hydronic piping, or a packaged unit if you already have air ducts. Ductless heat pumps can be a great option in apartment buildings where each dwelling has individual heating and cooling systems. In new constructions, consider a geothermal heat pump, since it is much easier to install the underground water loop when there is no building yet.

If you are ever unsure about which systems are best suited to your project, it is always wise to recruit the help of experienced MEP engineers.
