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.
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.
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.
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?
