These days, we’re all looking for ways to save money, especially on our utility bills. One smart way that home owners are finding for saving money is areversible air conditioner, which cools in the summer and heats in the winter with a heat pump. What is a heat pump? How does a heat pump work? The answers to these questions will help you decide whether a heat pump is right for your home.
Let’s start with how an HVAC system works. An air conditioner removes heat from a house and blows it outside. If you reverse its operation during the winter, the same equipment can be used to remove heat from outside and bring it indoors. Such a reversible air conditioner is called a heat pump.
Now, how does a heat pump work? The theory behind taking cold air and making it blow hot isn’t rocket science (but it is physics – the Second Law of Thermodynamics). In order for cold air to become hot, the cold air has to pass through something that is even colder (such as the refrigerant canister in the heat pump). Now there’s a difference in temperature and the unit can extract the heat from the air that is being processed. So taking outside air that’s 45° and lowering it to 40° (a difference of 5°), means you can take that hot air and raise the temperature in the house 5°. Amazing!
Most people in the Phoenix area already have a heat pump. In areas where cooling things down is more important than heating things up, you’ll usually find a heat pump. Now you know how a heat pump works, make sure it’s ready for the winter season. At John’s Refrigeration, we know, too. We’ve been around for over 45 years, servicing and installing HVAC systems.
