UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The ...

Heat pumps are emerging as an efficient solution for space heating and air conditioning, especially when used in variable refrigerant flow systems. They can match the most efficient air conditioning ...

If defrost isn’t working, something in the chain is broken. This step-by-step approach shows you exactly where to look and what to test.
