Best Practices on Air Conditioning for Business

Achieving thermal comfort in the building is not easy at times with so a lot of factors impacting on the heat or cold air coming from the air conditioning system

To make an effort and combat some of the things which can damage the efficiency of air conditioning, provided below are some dos and don’ts which will undeniably assist in keeping the right temperature of the building.

THE DOS

• Get better insulation

The best way to combat the building from the many ways in which the building can leak warm or cool air is to improve insulation to provide the air conditioner a fighting chance to regulate temperatures. Make sure that windows and doors are double glazed with the most up-to-date insulation in your walls and ceilings. 

• Put on your calendar the thermostat

Every building has a routine, with people entering and exiting at specific times. For this reason, savings can be enjoyed by setting the thermostat to reflect when people will be around to benefit. A lot of money can be saved by having the system turn itself on and off rather than leaving it on the whole day. 

• Service your system frequently

Although it appears like an additional expense, savings can be felt in the long run by having maintenance and refurbishment services performed on a regular basis. A careful check up can likewise perk up the unit’s efficiency, helping you lessen power consumption.

THE DON'TS

• Step out of your home without an opened windows and doors

There’s a need to allow the system to do its job once heating/cooling the room. Every outside influence on the core room temperature could witness the system over compensating or, worse still, missing any kind of impact at all, which misuses money and trying to achieve thermal relief through air conditioning a pointless attempt. 

• Avoid keeping it switched on all day and night

There is a common myth that once the airconditioning unit is  on all through the night lowers energy consumption. The judgment behind this is that it costs more to start the unit up and get to the temperature at its best, which is not true however, as the unit is actually at its most energy efficient as it starts. 

• Never use out-of-date unit

No one can’t expect the best results when using old or damaged equipment, but rather spend more money to run an inefficient unit

Manufacture and use of greenhouse gases are the largest environmental impacts of air conditioner use

The electricity produced to power air conditioning brings both global and personal health consequences. In burning fossil fuels like coal to supply electricity to homes and workplaces, power plants release clouds of soot and other pollutants into the environment, including mercury and carbon dioxide (CO2). Air conditioner use in the United States results in an average of about 100 million tons of CO2 emissions from power plants annually.

Ozone-depleting chlorofluorocarbons (CFCs) which was used as cooling agents in the past have been substituted with hydrochlorofluorocarbons (HCFCs) which deplete 95 percent less ozone. However, increasing demand for air conditioners in hot climates like India and China has amplified the chemical's output in developing countries from 20 to 35 percent yearly, causing damage at an alarming rate and possibly setting back ozone recovery by 25 years. In industrial countries, HCFCs are substituted with ozone-safe cooling agents and was banned in the United States in 2010. But HCFCs is allowed in developing countries through 2040, and since they're still cheaper to use than ozone-safe chemicals, production in developing countries has increased fivefold until 2010.

For conscientious disposal, federal law obliges that HCFCs be retrieved from air conditioners and other appliances before they are dismantled for recycling or tossed in landfills, and the Environment Protection Agency (EPA) is authorized to impose fines of up to $25,000 for failure to conform with regulations.

In the midst of scorching heat waves, air conditioning serves as a lifesaver, defending against heat stroke and hyrthermia. However, without suitable maintenance, air conditioners can also be a health hazard. Dirty filters can allow allergens, pesticides and other particulate matter to go into one’s home from the outside, posing threats to indoor air quality. Exposure to these pollutants can trigger a host of health problems, including allergies and asthma and eye, nose and throat irritation.

Importance of ducts

Duct leakage causes not to produce enough cold air which can sap 20 to 40% of the energy out of even a well-operating air conditioner, if the ducts pass outside the cooled space (attics, crawlspaces and garages). Ducts outside has to be proper insulated either by a keen home owner or a professional contractor.

Ventilation

An ideal air conditioner should heat, cool, clean, ventilate, humidify and dehumidify as needed to provide health and comfort. The second most important objective of air conditioning is to provide ventilation.

Without sufficient ventilation, contaminants generated indoors can lead to health and comfort problems. It is recommended to have at least enough ventilation to exchange the air inside house once every four hours, depending on house design.

Older homes have the tendency to have leakier walls and leakier ducts and typically obtain sufficient ventilation through such leakage. These leakage and infiltration may not be the most energy efficient method to ventilation and is an opportunity for savings.

Most new homes and some existing homes are relatively tight.  Hence, they need mechanical ventilation to meet minimum ventilation requirements.

Heat versus humidity

Humidity control was the problem that originally stimulates the need for air conditioning. Lack of humidity control in hot, humid climates can lead to mold growth and other moisture-related problems. High indoor humidity can cause health and comfort problems.

Modern air conditioners dehumidify as they cool which can be seen on the water that drains away, but this dehumidification is incidental to their main job of controlling temperature, which cannot separately control both temperature and humidity.

In hot, humid climates the incidental dehumidification that takes place may not always be enough to keep the indoor humidity conditions suitable. Professional recommends roughly a 60% relative humidity maximum at 78F.) The maximum dehumidification occurs not at the hot times of the year when the air conditioner is running a lot but at mild times of the year when the air conditioner runs very little.

Although there are some leading edge air conditioning systems that offers to independently control humidity, conventional systems may not be able to adequately control the problem and can cause discomfort or mold problems in particular conditions. Some modern high-end systems have enhanced dehumidification, but when the existing system cannot amply dehumidify, it may be important to acquire a stand-alone dehumidifier.

Lessen the need for dehumidification:

Avoid setting the thermostat to the “fan on” position. In this position, the fan blows air continually whether the cooling system is running or not, and one key impact is that a lot of the moisture the system just took out of the air is blown back into the house before it can drain away.

Use exhaust fans on moisture-producing activities. Cooking, bathing, washing, and identical endeavors produce a lot of moisture inside the house. Drain that moisture directly outdoors by a fan. Likewise, avoid drying clothes indoors except with a clothes dryer that is drained directly outdoors.

Avoid opening the windows or use ventilative cooling when it is too humid outside.

10 Significant Tips on Maximization of Air Conditioning Efficiency

Air conditioning may be a luxury for others, but a necessity to some.  Considering the expense of the equipment and the power to run it, consumers of this equipment need an awareness that would assist to be able to take care of it and use it suitably.

Developed in 1908, the first functional characterization of air-conditioning was defined by G. B. Wilson which Willis Carrier, the “father of air conditioning” employed, which was formulated to:

• Sustain appropriate humidity in all areas of a house/building.
• Free the air from unnecessary humidity on particular periods.
• Supply a permanent and sufficient distribution of ventilation.
• Proficiently take out from the air micro-organisms, soot, dust, and other foreign bodies.
• Capably make room air cold on specific periods.
• Heat the rooms during winter.
• Provide an apparatus that is cost-efficient in acquisition or after-sales.

Now let’s find out the 10 noteworthy reminders on optimization of air conditioning efficiency:

1). How does cooling process take place in air conditioner?

  

2). Ton of Cooling

  

3). Regulating costly repair on poor ventilation

  

4). The role of air conditioner filters

  

5). System Maintenance
