There are many cases when you will have to convert kWh to BTU. Luckily, it’s very easy to do this conversion. Let’s quickly summarize what kWh and BTU mean: kWhย stands forย kilowatt-hour. This is a unit of electrical energy and is defined as an amount of electricity used to run a 1,000W (1kW) device for 1 … Read more
In many cases, you will need to convert BTU to kWh. For example, if you need to know how many kWh does your 12,000 BTU air conditioner uses every hour, you just need to convert BTU to kWh. Let’s first summarize what BTU and kWh are: BTU stands for British Thermal Unit. This is a … Read more
With all batteries, we best know amp-hours (Ah) and watt-hours (Wh). This will allow us to estimate how long will a battery run an electric device or evaluate how many amp-hours do you need for running an electric device. That’s why we will look at how to calculate amp hours of a battery. Here’s the … Read more
Dew point has always been difficult to calculate. Namely, the dew point is a temperature at which moisture in the air starts to condensate on the surface (forming dew). This is a classic gas to liquid conversion. To simplify how to calculate the dew point, we are going to look at the dew point formula, … Read more
SEER stands for Seasonal Energy Efficiency Ratio. This is the most commonly used metric to denote how energy-efficient HVAC units like air conditioners, heat pumps, and furnaces are. We are going to look at how to calculate the SEER rating. The SEER rating is not as easily calculated as the EER rating (Energy Efficiency Ratio). EER … Read more
Converting CFM to CFH is incredibly easy. Both are units that measure airflow. Basically, you just multiply CFM by 60 to get CFH. CFM stands for Cubic Feet per Minute. 100 CFM airflow means that 100 cubic feet of air is produced by a device in 1 minute. CFH stands for Cubic Feet per Hour. … Read more
Both CFM and SCFM are units for measuring airflow. That can be an airflow generated by an air conditioner, furnace, ceiling fan, compressor, and other HVAC devices. CFM stands for Cubic Feet per Minute. SCFM stands for Standard Cubic Feet per Minute. As we see, the only difference between SCFM and CFM is that inclusion … Read more
Loudness is measured in decibels, right? Most of us are familiar with decibels (dB) when describing how loud something is. That’s why we might be surprised when we see noise levels expressed in ‘Sones’. We have prepared a Sones to dB calculator to help you out. To convert Sones to dB, we use the following … Read more
IPLV or Integrated Part-Load Value is a metric used for adequately assessing the energy efficiency of chillers and air conditioners in realistic conditions. The key metric that we use for the energy efficiency of any HVAC appliance is COP (Coefficient Of Performance). Supplementary metrics include EER, SEER, CEER, and HSPF ratings. Where does IPLV fit … Read more
Correct wire sizing is very important. Especially safety-wise. One of the most common questions we get about wiring is ‘what is the wire size for a 60 amp breaker?’. A lot of homeowners make this very common mistake: They use 6 AWG wire for a 60 amp breaker because 6 AWG gauge wire has 65A … Read more
