HSPF Rating: What Is A Good HSPF Rating For Heat Pumps?

what is hspf rating

When it comes to heating devices, there is no single specification more important than the HSPF rating. HSPF rating is the key metric for all heating devices; be it heat pumps, furnaces, or water heaters. Understanding it gives you the fundamental insight in all heating devices. In fact, it’s so important that every larger heating … Read more HSPF Rating: What Is A Good HSPF Rating For Heat Pumps?

16 SEER vs 14 SEER: Which AC Unit Is Better?

calculation which unit is better 16 seer or 14 seer

The SEER rating is a universal rating to determine the energy efficiency of air conditioners. SEER stands for ‘Seasonal Energy Efficiency Ratio‘; this is the key metric to determine how much electricity our AC unit will draw. A large number of AC units have either 14 SEER or 16 SEER. When figuring out which unit … Read more 16 SEER vs 14 SEER: Which AC Unit Is Better?

Watts To Amps Converter (With 120V Examples)

watts to amps calculator and table

Example: An air conditioner is powered by 800 Watts. How many Amps is that? It’s 5 Amps. To convert electrical power to electrical current (Watts to Amps), we need to use the electrical power equation: P = I*V where: P is electrical power, measured in Watts (W) I is electrical current or amperage, measured in … Read more Watts To Amps Converter (With 120V Examples)

CADR Rating: What It A Good CADR Rating For Air Purifier?

what is cadr rating

Here’s a bit of history of how CADR rating was invented. In the 80s, all talk with air purifiers was about maximum airflow (measured in CFM) and filters. But nobody really could tell how effective this or that air purifier was at actually removing pollutants such as dust, smoke, mold spores from indoor air. AHAM … Read more CADR Rating: What It A Good CADR Rating For Air Purifier?

Air Changes Per Hour Calculator (CFM Based Formula)

calculator that calculates air changes per hour from cfm and ach formula

ACH or Air Changes Per Hour is a metric that tells us how many times an HVAC device can fill up the full volume of a room with air. This is especially useful when comparing different air purifiers or air conditioners. Example: Let’s take an air purifier with 250 CFM airflow. We put it in … Read more Air Changes Per Hour Calculator (CFM Based Formula)

Convert EER To COP And COP To EER [Calculator]

formula that converts eer to cop and cop to eer

There are several HVAC metrics for energy efficiency. In many cases, the Energy-Efficiency Ratio (EER) is specified on the specification sheets. However, one of the most basic heating/cooling metrics – Coefficient Of Performance (COP) – is not. Fortunately, you can easily calculate COP from EER (as well as EER from known COP) with these two … Read more Convert EER To COP And COP To EER [Calculator]

Convert EER To SEER Rating (Calculator + Chart)

equation that converts eer to seer

EER and SEER both measure the energy efficiency of HVAC devices such as air conditioners and heat pumps. EER = ‘Energy Efficiency Ratio’ measures energy efficiency at 100% cooling load, 50% humidity and 95F to 80F temperature difference. SEER = ‘Seasonal Energy Efficiency Ratio’ measures energy efficiency throughout the summer season (June, July, August). We … Read more Convert EER To SEER Rating (Calculator + Chart)

Understanding EER: What Is A Good EER Rating For AC?

chart of below average and above average energy efficiency ratio rating of portable air conditioner

EER or Energy-Efficiency Ratio is an energy performance rating for cooling devices. You will find them in any air conditioner specification sheet. It’s invaluable when you try to compare different air conditioners as far as energy-efficiency is concerned. What does EER mean? By definition, it provides you with a ratio of useful cooling output (in … Read more Understanding EER: What Is A Good EER Rating For AC?
