For example, in winter, it takes heat from the outside air (yes \u2014 even when it\u2019s cold) and moves it indoors to warm your home. In summer, it works in reverse, removing heat from inside and releasing it outdoors to keep your space cool. In cooling mode, the cycle reverses, removing heat from inside and rejecting it outdoors \u2014 essentially functioning as an air conditioner. So a heat pump can be used as an AC. It is worth to understand that not every AC unit can work in reverse mode if it wasn&#8217;t designed to do so. It would only provide cooling capability.<\/p>\n\n\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-a1df8100029bde8ca9e74cc4c0fc333a\">The name \u201cheat pump\u201d comes from how it works: it&nbsp;pumps&nbsp;heat, similar to how a water pump moves water from one location to another. Rather than generating heat directly, it only transfers existing heat using electricity and a special refrigerant cycle. <\/p>\n\n\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-489aeae7864cf4721f88c17b807ae616\">A simple way to think about it is like&nbsp;a home refrigerator in reverse. Your fridge pulls heat out of food and releases it into the kitchen through the coils on the back. A heat pump uses the same principle \u2014 except its goal is to keep your whole home or office comfortable, either by bringing heat in or pushing it out depending on the season.<\/p>\n\n\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-c3acca27d2bfe308206d5ca63586959c\">Because heat pumps move heat instead of making it from scratch, they\u2019re often much more energy-efficient than traditional heating systems. That efficiency can mean lower energy bills and reduced environmental impact, which is why heat pumps are becoming a popular choice for modern homes.<\/p>\n\n\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-7906f006770a8dcf4e9be659f5eff38f\">A simple heat pump consists of one condensing unit and an evaporator, along with a compressor and expansion valve. When thinking multi-zone systems, there is going to be more than one evaporator connected to such system. If there&#8217;s a way for those evaporators to transfer energy between themselves without rejecting excess heat to the atmosphere, we&#8217;re then talking about heat pumps with heat recovery capabilities, or simply heat recovery systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A heat pump is a device that moves heat from one place to another instead of creating heat.
