Lately Hundreds of individuals have been taking a look at our site looking for Construction Engineering near the Chicago area. That is due because of the following we have built in this kind of work. With that said, a lot of general contractors from Lincolnshire to West Chicago, IL, don’t know that New York Engineers is also a top choice for anyone looking for HVAC Chicago, IL!

The search for cost effective buildings involves energy-efficient HVAC system design. This will likely include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for that HVAC systems will come primarily from five different bases including lighting (cooling), the construction envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a purpose of either the machines necessary so as to introduce it in to a space and control contaminant concentration or the amount of people who will use the area. In nearly all climates from the eastern and southwestern parts of the usa, to lower outside air-flow helps you to save energy whenever the

outside air is either warm and humid or very cold.
Governing the ventilation rate will probably be dependant on occupancy which is called a variety of demand control ventilation. This really is a common type of energy conservation policy which is used for rooms with occasional or heavy occupancy. Having heating and cooling loads reduced as low as possible can be achieved through the use of an increased performance building envelope, occupancy sensors, and performance lighting that exploits daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Techs

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

HVAC engineers will be the individuals who watch over setting up of air conditioner systems for residential and commercial buildings. They spend plenty of their time in offices doing advanced level organization and preparation of installations nonetheless they do also visit job sites every so often.

In contrast, HVAC technicians usually do a lot of the hands-on work with repair and maintenance. A HVAC technician may deal with an engineer to perform some of the installation task, specifically for smaller jobs. Generally HVAC techs do considerably more travel and could spend time and effort changing filters, identifying leaks, doing recharges or decommissioning old and outdated systems that use old refrigerants.

HVAC engineers might have the chance to make more decisions about systems that are used, and they also are definitely the individuals who would offer advice about the most sensible refrigerants and which systems would work best with a bigger building. In the industry, there is certainly some challenge between ‘the suits’ and ‘the ones which get their hands dirty’, but both jobs do require a good familiarity with how air cooling works. In recent times many Internet users have been browsing the NY-Engineers.Com website looking for things like HVAC Companies Chicago Il.

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

Construction Engineering Pdf

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.
