Energy Efficient Cooling and Air Conditioning Tips
Air conditioning and cooling are among the most important inventions of the past century. They made wartime and summer blockbusters and supplies possible.
Cooling, however, places an enormous strain on the power system and produces huge amounts of pollution. This special IEA report raises awareness about the effects of this demand and provides solutions.
Energy Efficiency
When selecting an air conditioner energy efficiency is an important factor. The upgrade to a more efficient conditioner will save on your expenses for energy and reduce the environmental impact. Air conditioners are rated with several different energy efficiency ratings, such as SEER, EER, and HSPF. These ratings indicate how much an air conditioner can cool using a certain amount of electricity. The higher the rating, the more efficient the unit. The SEER rating of the system can be located on its yellow Energy Guide Label or by searching “SEER ratings”.
When you are looking for a new air conditioning system, search for one with a high SEER rating. This rating indicates how the unit performs in normal conditions in a given season. A higher SEER rating can lower your energy costs and consumption if you are replacing an older model.
Air conditioning systems are affected by other causes as well. Insufficient humidity in the indoors, insufficient maintenance and leaks in ducts, for instance, can make your system be more demanding and consume more energy. Making sure you are keeping up with routine maintenance and sealing leaks from ducts are simple steps to increase the efficiency of your system.
Commercial cooling systems are also susceptible to concerns about energy efficiency. These systems make use of a combination of packaged or split-compressors and huge pipe networks to provide cooling throughout the building. They may also include steam systems, which require specialized maintenance to keep the pipes from becoming blocked.
Additionally to that, many of these huge systems are controlled by something called a Building Automation System (BAS) which connects all heating and cooling systems in the building into one central system. Verde has helped optimize the efficiency of the systems by offering retrocommissioning recommendations that provide rapid paybacks.
Energy efficiency in cooling and air conditioning is a major component of global efforts to combat climate change. We need to ensure that cooling devices are efficient and that consumers are demanding them. In the meantime, there are a variety of actions we can take to help reduce our energy use and greenhouse gas emissions.
Indoor Air Quality
Indoor air quality is a serious health concern for many people who spend a substantial portion of their lives inside buildings. There are numerous ways to improve IAQ and prevent common issues like asthma, allergies fatigue, asthma, etc.
Particulate matter and volatile organic compounds and carbon dioxide are three of the most prevalent pollutants in modern office and home buildings. These pollutants are released into the air by a variety of activities, like cooking, cleaning, and smoking cigarettes, and can lead to respiratory issues and allergic reactions.
A high level of moisture may also have a negative impact on the quality of air. Mildew and mold can thrive in moist air, which can cause respiratory problems. Monitoring humidity and keeping the moisture level low is essential to avoid these issues. This can be achieved by regularly vacuuming and dusting, cleaning bedding, soft furnishings and using a dehumidifier or humidifier based on the humidity gauge.
Aside from the obvious health benefits in improving IAQ can enhance the comfort in homes. A home that has high levels of air pollutants for instance, may smell musty. It can also cause irritation to eyes, itchy skin, and a stuffy feeling. Installing an air purifier and keeping the HVAC system can help to prevent these issues. Also, make sure that you open windows and doors to let air flow in when needed.
Poor air quality can trigger headaches, problems with concentration, and a general unwellness. Although these symptoms may disappear after leaving the area, prolonged exposure could cause health problems that are already present and could lead to serious health issues.
The main factor that affects IAQ is the speed that fresh air replaces stale air, a process known as ventilation. This can be affected by the weather, room occupancy rate and the design. There are many methods to improve IAQ. These include introducing plants in the house, opening the windows and doors whenever possible, and making sure that the HVAC system is working properly. If you’re looking to go further, we recommend that you talk to a Comfort Specialist about an indoor air assessment.
Smoke Pollution
Heat pumps and central air conditioning systems are effective in removing biological contaminants like bacteria, molds pollen, pet dander, and mold. However, they do not remove smoke particles. The tiny particles of smoke from wildfires are extremely dangerous and easily get into your eyes, nose and throat, causing symptoms like burning eyes or itchy eyes, congestion, a runny nose and coughing. They can also cause irritation to your lungs and aggravate chronic heart and lung conditions. The tiny particles of smoke can lodge deep into your lungs, triggering a variety of health effects such as worsened asthma, bronchitis and damage to your lungs and heart.
The haze that engulfed New York City last week was caused by forest fires burning in Canada. It can also cause dangerous air quality issues across much of the north and south of the United States. The thick smoke haze can reduce visibility and can cause respiratory stress for anyone who must be outdoors.
Unfortunately, there is no way to completely block smoky air from entering your business or home through doors and windows particularly older homes with lots of cracks and drafts. However, you can take steps to minimize the amount of smoke entering your home or business.
Keep all windows and doors closed when it’s smoky outside. This can cut the amount of smoky air by 30 percent. If you can, place damp towels around the door frames and cracks to stop the flow of smoke into your home or business.
If your HVAC system is in an recirculation mode, make sure to turn it off during smoky conditions. This will allow your HVAC to take the smokey indoor air, rather than the air being recirculated. If your structure has ducts that connect to areas where contamination is likely to be high, for instance parking garages or loading docks, you should ensure that these ducts are isolated from the rest of.
The EPA suggests that you change your HVAC filters more often during smokey conditions in order to ensure that they are effectively removing pollutants from the air in your home. Choose a filter with an efficiency reporting value (MERV) of 13 or higher, as these filters are specially designed to remove smoke and other gaseous air pollutants.
Supercooling
In recent years, supercooling has been an increasingly popular method of reducing energy consumption. It’s based on the notion that electricity costs don’t vary by amount at any given time of the day. In reality, the majority of electricity companies offer “time-of-use” plans that provide different off-peak and peak rates. Supercooling allows homeowners cool their homes in advance during off-peak hours, so they don’t have to run air conditioners at those expensive summer peak hours.
This requires a programmable thermostat that can adjust automatically. However, even with this, homeowners must be aware of and study their electric usage patterns and figure out when it’s most cost-effective to run their air cooling system. Many homeowners save around 25% or more off their energy bills through this method.
To keep the home cool, the homeowner sets their AC to a lower temperature in the morning and maintains it at that setting for a few hours. The home’s walls are cooled by the cooling furniture, floors, flooring and fixtures, as well as the air inside. Then, when peak energy-cost hours arrive the homeowner cranks the air conditioning up and runs it until it is turned off for several hours.
This method is efficient because it doesn’t only mean making the air inside the house cooler. It’s also about preventing heat from entering the house through windows, doors and other leak points. This is why homeowners should ensure that their homes are properly insulated and insulate any leaky or drafty areas. It is also recommended to cover windows to block out the sunlight, particularly in areas that receive direct sunlight during the hottest hours of the day. Also they should ensure that all doors and windows are sealed tightly to prevent air from escaping during cooling cycles. They should also think about using smart thermostats to help them remember when to start and stop cooling. This will allow homeowners to cut down on their energy bills without worrying about forgetting when to turn off or on the system.
