Measuring the efficiency of heat pump – What are the possible ways to do so? |
Posted: April 7, 2014 |
Are you searching for a suitable way to heat and cool your precious home? If yes, then why don’t you choose heat pumps? Thus, there arises an important question, “How will you measure the efficiency of your heat pump?” Well, you can do so by four kinds of measurements. You need to know that they are used in order to understand the efficiency of your heat pump. You may use any of these measurements at any time. One thing you should remember when you compare the measurement of heat pump is the high the number may be, the high the pump’s efficiency is going to be. Heat pump efficiency – Some ways of measurement There are four ways by which you can measure the efficiency of your heat pump. They are: Coefficient of Performance (COP) Energy Efficiency Ratio (EER) Heating seasonal performance factor (HSPF) and Seasonal energy efficiency ratio (SEER) Coefficient of Performance (COP) is the commonest way to measure the efficiency of heat pump. It is the ratio of BTU heat output of heat pump to BTU electrical output. You need to know that water heat pumps have 3-5 ratings. On the other hand, air source heat pumps have 2-4 COP ratings. With the drop in outside temperature, air source pumps COP will decrease. Thus, if you’re going to make a comparison between these ratings, then you need to be sure that both of them are based on the same temperature of the outside air. Energy Efficiency Ratio (EER) is another way to determine the efficiency of heat pump. This helps in assessing the efficiency during cooling of a particular unit. You need to know that this rating is used for the air conditioners too. If EER rating is high than ten, then it is certainly a good machine. Thus, the higher the number may be, the better will be performance of the heat pump. These efficiency measurements of heat pumps are mostly laboratory or factory tests. The heat pump may have different measurement when it is in use. However, this measurement can differ based on the condition of the weather or the amount of extra heat needed. As such, the best measurement is the one that is based on the seasonal calculations. The seasonal ratings are heating seasonal performance factor (HSPF) and seasonal energy efficiency ratio (SEER). The Heating Seasonal Performance Factor helps to measure the efficiency of heat pumps. If the rating is in between 5-7, then it is certainly a good rating. On the other hand, Seasonal Energy Efficiency Ratio is the amount of cooling in BTU's. A good SEER rating is the one that is between 8-10. You need to know that heating seasonal performance factor and seasonal energy efficiency ratio have better value in assessing the efficiency of the unit. This is because both of them are based on the present season when the unit is going to be used. Thus, in case of HSPF, 5-7 is considered to be a good rating and for SEER, 8-10 is definitely a good rating.
