When used along with other best practices recommended by CDC and others, increasing ventilation can be part of a plan to protect people indoors.
In general, the greater the number of people in an indoor environment, the greater the need for ventilation with outdoor air. In other words, the ventilation rate should be based on the number of people that occupy an indoor space and a few other factors. Also, make sure high-traffic areas have additional ventilation. In addition to helping reduce risk from airborne transmission of viruses, improving ventilation also benefits indoor air quality by reducing exposure to products used for cleaning and disinfecting potentially contaminated surfaces.
When there are known or suspected cases of COVID in the household, additional precautions are recommended. Opening windows and doors when the weather permits , operating window or attic fans, or running a window air conditioner with the vent control open increases the outdoor ventilation rate in a home. Do not open windows and doors if doing so poses a safety or health risk to children or other family members e. Local bathroom or kitchen fans that exhaust air outdoors and remove contaminants directly from the room where the fan is located also increase the outdoor air ventilation rate.
Most schools, offices, and commercial buildings have heating, ventilation, and air conditioning HVAC systems with filters on them. Typically, these systems are maintained by building or HVAC professionals. Professionals who operate school, office, and commercial buildings should consult guidance by ASHRAE formerly known as American Society of Heating, Refrigerating and Air-Conditioning Engineers , and other professional and government organizations for information on ventilation and air filtration to help reduce risks from the virus that causes COVID In general, increasing ventilation and filtration is usually appropriate; however, due to the complexity and diversity of building types, sizes, construction styles, HVAC system components, and other building features, a professional should interpret ASHRAE guidelines for their specific building and circumstances.
Increasing ventilation with all or mostly outside air may not always be possible or practical. Air conditioners have an automatic system. When you set the cooling level to a specific temperature, the air conditioner starts giving off cool air. The temperature monitor or thermostat in the AC constantly keeps a check on the room temperature.
As soon as the room temperature is up to the level you pre-entered, the AC will turn itself off. As soon as the temperature drops, it will turn on again.
This is a feature designed to optimize the AC's performance while providing the cooling you desire. When the temperature in the room reaches the preset level, the AC turns off to make sure that the room is not getting too cold. This keeps the users comfortable. Otherwise, the AC would make the room uncomfortably cold. All air conditioners, regardless of the type, have this feature. You can enter a temperature level and the unit will maintain it.
Another reason the AC is designed in a way that it turns off automatically is to conserve power. If an air conditioning unit does not turn off, it will work constantly and spike up your electricity bill. All air conditioners are rated to cool a specific space. This rating is directly related to the cooling capacity of the AC. If you install the AC in a larger room, it will work harder and use more electricity. In addition, the cooling will also be ineffective. The same concept applies when the windows are left open.
In order to make sure that you make the most of your investment, you have to minimize the stress placed on it. You also have to make sure that heat does not enter the room.
At the same time, you have to make sure that the cool air does not leak. The best practice is to get a slightly larger cooling rating AC for a smaller room. This will provide efficient cooling and also keep your energy costs down. For instance, if an air conditioner is rated to cool a room which is sq. This means that the AC is larger than the square footage needs. Not only will it cool the room faster, it will keep it at a moderate temperature. However, if done improperly by getting an AC with a capacity that is far too large for your room, you will have spent unnecessary money.
A large air conditioner will not have to work hard to cool a small room. This way you will be able to keep your maintenance costs low. In addition, since the air conditioner will easily maintain a steady temperature in the room, it will only turn on once in a while. The rest of the time, it will be on standby, monitoring the room for a rise in temperature. This will keep your electricity costs low as well. There are many ways you can keep a room cool.
Some of these tips are quite basic and do not require much effort. However, if those tips do not work, you should opt for a more advanced method. Let's look at ways you can keep your room cool:. However, this will only work for areas where the temperature does not spike. Areas that are warmer require a different approach. Protecting the windows from sunlight can be tricky.
Even if you draw the curtains, sunlight will still heat the room if the temperature is too high. In such a scenario, you should consider getting window tints. These impurities will plaster its evaporator coil, fan motor, ducts, and electronic components. If this buildup is substantial, it can trigger breakdowns and escalate your electricity bills. Dust on the evaporator coil impedes the cooling process. Dirty filters constrict airflow through the air handler.
This drives the AC to run longer. A clogged air filter paired with a dusty evaporator coil may cause the coil to freeze and possibly fry the compressor.
The experts at Progressive Air Systems can effectively diagnose and remedy the problem or give you insightful guidance if your system needs to be replaced.
Why leave the air conditioner on? Well, in the summer, air is going to heat up fast, and your house is going to start cooking. When you finally turn on your AC, it will need to strain to get your house nice and cold. An overworked air conditioner can also malfunction, wear out, or need to be replaced.
Leaving windows open before turning on the air conditioner is an open invitation for humidity. The longer you leave them open, the more that humidity can permeate your home. Along with keeping your house cool, air conditioners keep it free of excess humidity.
By the time you close your windows, your AC has to do double-duty to eliminate humidity, and your electricity bill will reflect this. This creates vacuum pressure that will force the cool air out of your window and siphon air from other gaps in your home. You can see this happening when your curtains are sucked against the window and flattened out.
In Florida and other hot climates, many homeowners turn off their air conditioners and open their windows at night. This actually makes homes less comfortable than they could be with the AC on and the windows closed. Research by the Florida Solar Energy Center FSEC analyzing several test homes determined that five more gallons of water accumulated in houses that were opened for the night than those that were closed. If you turn your air conditioner off at night, this excess moisture will actually make you feel more uncomfortable.
When the air has to crank on during the day, it will exhaust a lot of energy reaching an adequately cool temperature. Opening your windows when your air conditioner is running may feel refreshing, but it has more shortcomings than benefits. When your windows are open, and your AC is running, the unit can be stressed or damaged.
It may even break down completely. Progressive Air Systems is here to help get your air conditioning up and running.
