When it comes to setting the thermostat in your home, it's essential to have a temperature difference of 16 to 22°F between the supply air and the return air. This is known as a “Delta T evaporator” and when the temperature difference is within this range, your air conditioner will work optimally. Ideally, there should be a temperature difference of between 14 and 20 degrees Fahrenheit between the incoming air and the air being expelled by the air conditioner. This means that if the air entering the system is 75°F, the air leaving through the vent must be between 55°F and 61°F.The temperature differential simply refers to the gap between the outside temperature and the inside temperature.
For instance, if it's 100°C outside and you're trying to cool your home to 60°C, you'll face serious issues. A temperature differential of 40° is a huge margin for your air conditioner to repair it, and that will also be reflected in your energy bills. A good rule of thumb is that during the hottest days, when the dial reaches 100 degrees, it's best to set the air conditioner between 75 and 80 degrees. You can also supplement that slight temperature difference by closing the curtains in sunny parts of your home, putting ceiling fans and portable fans in rooms where there are people, and keeping a large glass of ice water handy. Additionally, make sure that your air conditioner is properly maintained to avoid any potential loss of efficiency or money due to items that could have been easily fixed, such as replacing dirty filters or cleaning coils. The “20-degree air conditioner rule” states that you should always keep your air conditioning unit no more than 20 degrees below the outside temperature.
This means that if outdoor conditions are 95 degrees, you must set the thermostat to no less than 75 degrees. In other words, the air conditioner temperature differential is industry jargon to describe the difference between indoor temperature and outdoor temperature. It's important because if the outside temperature exceeds 100 degrees Fahrenheit and you're trying to cool your house to 60 degrees, you'll have a lot of problems. To ensure that your home stays comfortable while keeping energy costs low, it's essential to understand how temperature differential works. By following these guidelines and making sure that your air conditioner is properly maintained, you can keep your home cool without breaking the bank.
