Energy Efficient Cooling and Air Conditioning Tips
Air cooling and conditioning is one of the most significant inventions of modern history. They made summer blockbusters and wartime planes and supplies possible.
Cooling, however, places immense strain on the electricity system and creates huge quantities of pollution. This special IEA Report aims to raise awareness of the issue and suggests solutions.
Energy Efficiency
When choosing a new cooling system, energy efficiency is a key aspect. Making the switch to a more efficient air cooling system will lower your expenses for energy and reduce the environmental impact. The energy efficiency of air conditioning units is assessed in various ways that include SEER and EER. These ratings indicate how much a unit is able to cool for a given amount of energy consumed. The higher the rating the more efficient the unit. The SEER rating of a system can be found on the yellow Energy Guide Label or by searching “SEER ratings”.
If you are looking for a new air conditioner, choose one with an excellent rating. This rating shows how well the unit performs under normal conditions in a given season. If you’re replacing an older model with a higher SEER rating will significantly reduce your energy use and expenses.
Other factors can affect the efficiency of air conditioning systems, too. High indoor humidity, the absence of maintenance and leaks in ducts, for instance, can cause your system to work harder and consume additional energy. Making sure you are keeping up with routine maintenance and sealing leaks in ducts are easy ways to improve the efficiency of your system.
Commercial cooling systems are also subject to energy efficiency issues. These systems use a combination split or packaged compressors as well as massive pipe networks to distribute cooling throughout the building. These systems may also include steam systems that require special maintenance to prevent the pipes from getting blocked.
Many of these large systems can also be controlled with an Building Automation System, which connects the cooling and heating systems into a single central system. Verde has been able to improve the efficiency of the systems by offering retrocommissioning strategies that offer rapid paybacks.
Energy efficiency in air conditioning and cooling is a key element of global efforts to reduce climate change. We need to ensure that cooling devices are super-efficient and that consumers demand these appliances. In the meantime, we can take other measures to reduce our energy use and greenhouse gas emissions.
Indoor Air Quality
Many people spend much of their lives in structures, and these structures can pose significant health threats in the event that the indoor air quality is not as good. There are numerous ways to improve IAQ and avoid common ailments such as asthma, allergies fatigue, allergies, etc.
Particulate matter (PM) and volatile organic compounds (VOCs) and carbon dioxide are the three main sources for pollution in modern homes and offices. These pollutants can be released into the air through a variety of actions such as cooking, cleaning and smoking. They can trigger allergies and respiratory issues.
A high level of moisture may also have a negative impact on air quality. The humid air encourages the growth of mildew and mold that can trigger respiratory problems. Monitoring humidity and keeping the humidity low is essential to avoid these problems. This can be done by regularly cleaning and vacuuming, washing bedding, soft furnishings and using a dehumidifier or humidifier based on the humidity gauge.
In addition to the obvious health benefits of improving IAQ, it can also increase comfort in your home. For instance, a house that is contaminated by air pollutants could become musty and smell unpleasant. It can also cause itchy skin, irritated eyes and a feeling of suffocation. These issues can be prevented by installing an air purifier, maintaining the HVAC system, and ensuring that windows and doors are kept open to let in air as required.
The symptoms of poor air quality can be varied and include headaches, difficulty in concentrating, and a general feeling of malaise. Although these symptoms may be relieved after leaving a area, prolonged exposure could worsen existing health issues and can even result in serious health issues.
The primary factor that affects IAQ is the rate that fresh air replaces old air, a process known as ventilation. This is influenced by the weather, room occupancy rates, as well as the design of the structure. However, simple steps can be taken to improve IAQ, including introducing plants into the house, opening windows and doors as much as is possible, and ensuring that the HVAC system is operating properly. If you’re looking to take it a further, we recommend that you speak with a Comfort Specialist for an indoor air assessment.
Smoke Pollution
While heat pumps and central air conditioners do a great job of filtering out the majority of biological contaminants, like bacteria, molds, pet dander, and pollen, they are not specifically designed to remove smoke particles. Smoke from wildfires is a source of microscopic particles which can cause symptoms such as burning or itchy eyes congested nasal, runny nose, and coughing. They can also cause irritation to the lungs and worsen the severity of heart and lung problems. The invisible fine particles in smoke can get stuck in your lung, triggering a range of health effects such as aggravated asthma, bronchitis, and damage to your heart and lungs.
The haze that covered New York City last week was caused by forest fires that are burning in Canada. It is also causing dangerous air quality conditions across large parts of the south and north of the United States. The thick fog of smoke reduces visibility and may cause respiratory distress to anyone who is required to be outside.
There is no way to keep smoke from entering your home through windows and doors especially in older houses with many cracks and drafts. You can make steps to decrease the amount of smoke entering your building.
Close all windows and doors when it’s smokey. This can cut down on the amount of smoky outside air by 30 percent. If you can, place damp towels on the door frames and cracks to slow the flow of smoke into your home or office.
If your HVAC system features the ability to recirculate air, be sure to shut it off when air is smoky. This will allow your HVAC system to exhaust the smoky indoor air, rather than recirculating it. If you have ducts in your building which connect to areas that can produce high concentrations of pollutants, like attached parking garages and loading docks, be sure to have those ducts independently isolated from the rest of the duct system.
The EPA recommends changing your HVAC filters more often when you are in a smokey environment to ensure that they are removing toxins from indoor air. Choose a filter with a minimum efficiency reporting value (MERV) of 13 or more, since these filters are specially designed to eliminate smoke and other gaseous air contaminants.
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 all times of the day. Most electricity companies offer “time of use” plans with different rates for off-peak and peak times. Supercooling allows homeowners to cool their homes in advance during off-peak hours, meaning they don’t need to run air conditioners at those expensive summer peak hours.
This requires a thermostat that is able to adjust itself automatically. However, homeowners still need to examine their patterns of usage of electricity to determine when their air conditioner is most cost-effective. Many people save about 25% or more off their energy bills through this method.
To keep the home cool, the homeowner should set their AC to lower temperatures the next morning and then keep it there for a few hours. The home’s walls are cooled by the cooling furniture, floors, flooring and fixtures, as well as the interior air. Then, when the peak energy-cost hours arrive, the homeowner turns the air conditioning up and runs it until it’s off for several hours again.
This strategy is effective because cooling isn’t just about keeping the air inside the home cool. It is essential to stop heat from entering your home through doors, windows, and other leaky points. This is why homeowners must ensure that their homes are properly constructed and insulated, and also make sure to insulate any drafty or leaky areas. It is also recommended to cover windows to block the sunlight, particularly in areas that are exposed to direct sunlight during the hottest parts of the day. It is also important to make sure that all windows and doors are tightly sealed to prevent air from escaping when cooling cycles are in progress. Also, they should consider installing smart thermostats that will assist them in ensuring that they start and stop cooling at the most optimal times of the day. This allows homeowners to keep their energy bills at a minimum without having to remember to turn the system off or on.
