The expansion of the heat absorption

The expansion of the heat absorption   In the refrigeration cycle, the refrigerant must undergo a change of state so that the heat absorbed by the refrigerant is the property of changing its state from liquid to vapor at normal room temperature. Have you ever felt the skin to become cold, when you put on it alcohol? But even if a little 'poured gasoline on your hands? This is because, alcohol or gasoline disappeared when it comes into contact with the skin. The result - the heat is removed from the skin and it feels cool! In a closed loop refrigeration circuit, the change of state from liquid to vapor is achieved mechanically by the pressure on the liquid at one end and forcing through a small opening at the other end. Once the liquid comes from the small opening that expands in the steam. The effect is similar to spray when you get the limit of your garden hose. But water is not a cooler. It does not feel cold, why not have a vapor. Bad example. But you have the idea? Restriction causes pressurized spray to another end.In many refrigeration circuits, the small opening is made in the form of a thermostatic expansion valve. Many other models using small capillary tubes. In large chillers, orifice plates are common. Each achieves the same goal - to increase the liquid and vapor due to evaporation tube survival cold.Discover best kept secrets of living and working in extreme temperatures.
