The capillary tube is a copper tube with a very small internal diameter. It is of very long length and it is coiled to several turns so that it would occupy less space.<\/span><\/p>\n<figure id=\"attachment_17248\" aria-describedby=\"caption-attachment-17248\" style=\"width: 940px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17248\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Capillary-Tube.png\" alt=\"capillary tube refrigeration \" width=\"940\" height=\"361\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Capillary-Tube.png 940w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Capillary-Tube-300x115.png 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Capillary-Tube-768x295.png 768w\" sizes=\"(max-width: 940px) 100vw, 940px\" \/><figcaption id=\"caption-attachment-17248\" class=\"wp-caption-text\">Construction of capillary tube refrigeration (Reference: <strong>electricalworkbook.com<\/strong>)<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_Capillary_Tube_Work\"><\/span>How Does Capillary Tube Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">When the refrigerant leaves the condenser and enters the capillary tube, its pressure drops down suddenly due to the very small diameter of the capillary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the capillary, the fall in pressure of the refrigerant takes place due to the small opening of the capillary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The capillary tube is a non-adjustable device that means one cannot control the flow of the refrigerant through it as one can do in the automatic throttling valve. So the flow of refrigerant would change according to the variation in the surrounding. That is why the capillary tube is designed for certain ambient conditions. However, if it is selected properly, it can work reasonably well over a wide range of conditions.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-7023\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3.jpg\" alt=\"\" width=\"1000\" height=\"1000\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3.jpg 1000w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3-300x300.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3-150x150.jpg 150w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3-768x768.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3-696x696.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/3-420x420.jpg 420w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Capillary_Tube_Size\"><\/span>Capillary Tube Size<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The size of the capillary tube is fairly critical. Unlike orifices, such as expansion valve seats, capillary tubes depend on their length as well as their diameter to determine their total restriction. A capillary tube is 1\u20136\u202fm long with an inside diameter generally from 0.5\u20132.28\u202fmm (0.020\u20130.09 inches).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A change in diameter on a percentage basis can change the flow more than an equal change in length. Restriction can also be changed by lengthening or shortening the capillary tub. The longer the tube, the slower the flow; the shorter the tube, the faster the flow.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Capillary_Tube_Function\"><\/span>Capillary Tube Function<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The capillary tube actually meters the refrigerant from the condenser to the evaporator. The diameter and length of the tube would determine the flow at a given pressure.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Because the capillary tube restricts and meters the flow of liquid to the evaporator, it helps maintain the needed pressure difference for proper system operation. The capillary tube and compressor are the two components that separate the high side from the low side of the refrigeration system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The capillary tube is used when the load is relatively constant. Capillary tubes are used as the throttling device in domestic refrigerators, deep freezers, water coolers, and air conditioners.<\/span><\/p>\n<figure id=\"attachment_17250\" aria-describedby=\"caption-attachment-17250\" style=\"width: 489px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17250\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/thermodynamics.jpg\" alt=\"capillary tube refrigeration \" width=\"489\" height=\"221\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/thermodynamics.jpg 489w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/thermodynamics-300x136.jpg 300w\" sizes=\"(max-width: 489px) 100vw, 489px\" \/><figcaption id=\"caption-attachment-17250\" class=\"wp-caption-text\">Thermodynamics of capillary tube refrigeration (Reference: <strong>sciencedirect.com<\/strong>)<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_Of_The_Capillary_Tube\"><\/span>Advantages Of The Capillary Tube<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The advantages of using the capillary tube as the throttling device in the refrigeration and the air conditioning systems are as follows.<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">The capillary tube is a very simple device that can be manufactured easily and it is not very costly.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The capillary tube has no moving parts. Therefore it doesn\u2019t need maintenance.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The capillary tube limits the maximum amount of the refrigerant that can be charged in the refrigeration system due to which the receiver is not required in these systems.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The capillary tube provides an open connection between the condenser and the evaporator hence during off-cycle, pressure equalization occurs between condenser and evaporator. This reduces the starting torque requirement of the motor since the motor starts with the same pressure on the two sides of the compressor. Hence, a motor with low starting torque (squirrel cage Induction motor) can be used.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It can be used for hermetic compressor-based systems that are critically charged and factory assembled.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It is compact in size.<\/span><\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-7022\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2.jpg\" alt=\"\" width=\"1200\" height=\"1198\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2.jpg 1200w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-300x300.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-1024x1022.jpg 1024w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-150x150.jpg 150w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-768x767.jpg 768w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-696x695.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-1068x1066.jpg 1068w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/2-421x420.jpg 421w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Disadvantages_Of_The_Capillary_Tube\"><\/span>Disadvantages Of The Capillary Tube<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Some of the disadvantages of a capillary tube are:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">These valves are not capable of adjusting themselves to the change of flow as per changing ambient temperature and load.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">It is susceptible to clogging because of the narrow bore of the tube, hence, utmost care is required at the time of assembly. A filter-drier should be used ahead of the capillary to prevent the entry of moisture or any solid particles<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">During off-cycle liquid refrigerant flows to evaporator because of pressure difference between condenser and evaporator. The evaporator may get flooded and the liquid refrigerant may flow to the compressor and damage it when it starts. Therefore critical charge is used in capillary tube based systems. Further, it is used only with hermetically sealed compressors where refrigerant does not leak so that critical charge can be used. Normally an accumulator is provided after the evaporator to prevent slugging of the compressor.<\/span><\/li>\n<\/ul>\n<figure id=\"attachment_17251\" aria-describedby=\"caption-attachment-17251\" style=\"width: 685px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-17251\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Schematic-illustration-and-components-layout-of-the-refrigeration-system-1-Evaporator.png\" alt=\"capillary tube refrigeration \" width=\"685\" height=\"527\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Schematic-illustration-and-components-layout-of-the-refrigeration-system-1-Evaporator.png 685w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/04\/Schematic-illustration-and-components-layout-of-the-refrigeration-system-1-Evaporator-300x231.png 300w\" sizes=\"(max-width: 685px) 100vw, 685px\" \/><figcaption id=\"caption-attachment-17251\" class=\"wp-caption-text\">A schematic diagram of the components of the capillary tube refrigeration system (Reference: <strong>researchgate.net<\/strong>)<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"What_Should_You_Consider_When_Choosing_a_Capillary_Tube_for_Refrigeration\"><\/span><b>What Should You Consider When Choosing a Capillary Tube for Refrigeration?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It is usually a very small diameter pipe available in diameters ranging from 0.76 to 2.16 mm that is used as a capillary tube.
