• How Your Commercial Refrigeration System Works

    You can save energy and money by working with a qualified HVAC contractor near Portland to install or upgrade your commercial refrigeration system . And when you watch the accompanying video, you’ll learn the basic principles of how your refrigeration system works. All refrigeration relies on the continuous movement of a cooler liquid through a tube that goes around the object that is to be cooled.

    Perhaps the most important component of an energy efficient refrigerator is the throttling device. Refrigerant liquid is elevated to a high pressure before being introduced to the throttling device. This device resists the refrigerant, which causes a significant drop in pressure. As the pressure drops, the boiling point of the liquid also drops, which causes it to begin evaporating. The heat required to evaporate the refrigerant comes from the liquid itself, which causes it to decrease its temperature.
