DEN is a unique evaporative cooling technology, performance-predicting, design software program. It uses data from current and historical weather centers and can accurately ascertain how much a building’s cooling system would “need” to run at different points of the year. DEN has several benefits; for example, it enables HVAC engineers to estimate how effective or costly a particular cooling system may be for a project. Here are some other benefits.
As the power demands of the modern era increase and building engineers continue to search out greener solution 100% fresh air and evaporative cooling concepts are coming more and more into consideration. But how do you design a 100% fresh air cooling system when weather conditions are constantly changing?
“Going green” has become a household phrase. We ask ourselves, “What can we do to help the environment?” In the same fashion, building owners advocate reducing their carbon footprint and work to design energy efficient buildings. To them, zero net energy (ZNE) is not a foreign concept. Even though the familiarity of ZNE is present, we recently learned that ZNE buildings are not mainstream, and while efforts are progressing, the uptick in ZNE design is only marginal. Why is this the case? In a recent issue of the ASHRAE Journal, experts clear up misconceptions of ZNE by clarifying the approach, highlighting the benefits, and providing recommendations on how to motivate building owners to make ZNE building a standard.
Marijuana plants are extremely sensitive. If the humidity levels are too high or too low, the plants become at risk of disease and are unlikely to grow to their full potential. When designing HVAC systems for grow rooms, it is critical to identify and maintain the right humidity levels or the grow room could suffer a great loss.
While amateurs use a variety of hacks to control humidity levels, HVAC techs and designers are able to create systems around certain types of HVAC units that make maintaining the humidity control much easier.
The Single Thread Farm is located on five acres between the Russian River and the historic San Lorenzo Ranch in Healdsburg, California. The property consists of rolling fields, chicken coops, fruit orchards, olive trees, bee hives, and a cattle paddock all surrounded by wine vineyards. The farm supplies the vegetables, fruit, herbs, flowers, honey, eggs, and olive oil to their award-winning Michelin-star eatery by the same name.
HVAC professionals consider a multitude of variables when designing systems for grow rooms. But, one issue that often gets overlooked is odor control. Growers are often restricted in how they handle the crops’ distinctive odors. A proper HVAC system can help control odor issues without compromising the humidity and temperature controls that are vital to crop survival.
Marijuana is one of the most valuable crops in the United States. The legal cannabis market grossed almost $9 billion in 2017. Analysts estimate that this industry will be worth as much as $21 billion in 2021. Like all other high-growth industries, the legal cannabis industry also presents opportunities for other businesses outside of the core cannabis growers and sellers. To benefit the industry and businesses outside the industry, grow rooms need to continue to thrive, and therefore, require specialized HVAC systems that keep this cash crop healthy and fresh, and sustainable.
When it comes to the design and operation of a data center, its critical to have the proper HVAC system in place. Without careful consideration and consulting from a HVAC professional, a data center owner can easily select the wrong system, causing the entire data center to be in jeopardy. There are six vital HVAC design features specifically for data centers. Installing an HVAC solution with these features will ensure optimal operation without compromising performance.
Data centers typically are high-density enclosed spaces that produce and distribute a significant amount of heat in a small area. This heat needs to be removed, and traditional comfort cooling systems often cannot remove enough of it. There is a critical need to house dedicated units with precision cooling capabilities. But not just any cooling system will do the trick. This ebook addresses five factors to consider in HVAC design for data centers. Keeping these five factors in mind will help ensure the HVAC system maintains a regulated temperature, is sustainable, and continues to help the data center perform its functions optimally.
Data centers have very specific HVAC needs that are different from most other industrial settings. When selecting HVAC equipment and designing a system specifically for a data center, the following three considerations must be top of mind: The location of the servers and other key equipment;
Access to electrical supplies and overall electric loads; and Appropriate parameters for temperature and humidity in different zones
Indirect + Direct evaporative cooling (IDEC) is a viable method to keep temperature and humidity within the ASHRAE comfort zone throughout most of the Rocky Mountain region. Air2O, the next generation of air conditioning systems, recommends designing for 100% outside air when applying an IDEC system in most applications.
In 2014, US data centers constituted 1.8% of total US power consumption, and this number is only expected to rise in the coming years. Now, for many, 1.8% may seem low, but building designers know power consumption can easily skyrocket as more and more data centers are built, so they continue to look for ways to optimize data center energy use.
Commercial kitchens are the nerve center of a food-based business. Any problems in the kitchen can quickly spin out of control and harm the staff, customers, and even the business. A well-run kitchen not only requires a dedicated staff, it also takes a well-designed HVAC system. If the kitchen doesn’t have a proper make up air unit, it can make working in the kitchen more dangerous and create a domino effect to everyone exposed, including harming the dining experience for customers, and ruining the business.
The HVAC industry is bracing for the planned phase out of Freon (R22) for commercial HVAC units. Many customers are still unaware of the phase out or are unclear about how it will affect them. The more you know about what is going to happen with R22, the better you will be able to prepare your customers for what needs to happen with their aging R22-dependent systems.
In the current competitive HVAC market, simply designing, building, and installing more efficient systems and equipment is no longer enough. Builders and building owners alike are increasingly worried about indoor air quality and how it affects the health of workers and the environment.
With advances in HVAC and new techniques in system design, HVAC systems can now play an important part in improving indoor air quality.
Water vapor or humidity is usually not considered an air contaminant or cause of health problems. Yet, studies show that when indoor humidity levels are out of range, it can have a detrimental impact on building occupants. Many experience adverse reactions and, long term can lead to illness. This post discusses how humidity can easily compromise health and comfort. With the proper cooling systems in place, balanced humidity levels can be achieved, which will allow for healthier and happier occupants.
Recent advances in technology have help evaporative cooling become a hot choice for many builders and HVAC technicians. But, many people still have some basic questions about everything from how evaporative cooling works to if really can deliver on all of the hype. Here are the answers to the five biggest questions about evaporative cooling.
Air conditioning has been credited with changing the way people live and work. However, industrial and residential air conditioning units continue to operate much the same way they have for decades.
There have been some marginal improvements when it comes to energy efficiency, but there has been surprisingly little innovation in the way traditional AC units work.
We can all agree that feeling hot is uncomfortable. It makes it nearly impossible to focus, and there is only so much you can do to keep cool. This discomfort is often due to the fact that many homes and businesses rely on outdated refrigeration-based air conditioning units to beat the heat. But, if you want to maintain healthy indoor air quality, save money, and keep cool, an evaporative cooling system may be the solution for you.
According to the U.S. Environmental Protection Agency, the term Sick Building Syndrome (SBS) is used to describe “situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.” The complaints may be localized in a particular room or zone, or may be widespread throughout the building.
According to WebMD, Sick Building Syndrome (SBS) affects millions of people every year. However, because of the nature of the condition, it can be difficult to establish that a particular health issue is the result of Sick Building Syndrome. Instead, most often a structure is found to have SBS based upon looking at the type and frequency of symptoms displayed by the works inside of the building as well as an inspection of the HVAC system and air circulation system.
Millions of men and women every year battle through mysterious symptoms and illnesses at work. Strangely, most of these symptoms seem to vanish once they leave the building. These people are suffering from Sick Building Syndrome, a poorly understood condition caused by the structures these people work in day after day.
Tata Technologies, owner of Jaguar Land Rover, constructed a new 30 million dollar European Innovation Headquarters in Leamington Spa, United Kingdom. The three story steel framed, 63,000 sq. ft office building will house nearly 600 staff working in emerging vehicle technologies.
Next door to the new Chicago Cubs Spring Training Facility in Mesa, Arizona sits the home of Brent Berge’s Riverview Toyota. The Berge Group, operators of eight auto dealerships in Arizona have been at the forefront in adopting energy efficiency technologies to manage rising energy costs in their facilities.
Neglecting building indoor air quality while pursuing other energy efficiency goals, such as tighter building envelops, can result in building environments that negatively impact the health, comfort and productivity of occupants (sick building syndrome) and therefore defeat the overall goal of building design, including reduced costs. Smoking areas, schools, labs, hospitals and positive pressure buildings will need even higher attention due to their higher ventilation rates requirements. Fresh air ventilation using a dedicated mechanical outdoor air system became a very important component for modern HVAC system design. The HVAC designer must therefore implement creative solutions to meet both conflicting requirements in an optimum manner.
In recent years the use of the word “Hybrid” has been on the rise, due to its commercial effect of adding the illusion of being energy-efficient and environmentally conscious. But for the sake of a true understanding of what Hybrid Air conditioning means, let’s first dig in to what the word hybrid means?
Moe Salem presented a technical paper, Energy Performance of Evaporative Recovery (ER) Using Cooling Tower & Coil Arrangements, the revolutionary game changer solution for energy recovery that was implemented recently at the Mall Of Qatar in Doha.
