Capillary tubes and plates with holes
Capillary is simply the length of the small diameter of the tube - its length and carried selected to achieve the required pressure differential. It is normally used only on small enterprises, its systems, for example. display cabinets, bottle coolers, ice-making machines and other Such systems usually have a constant loads, and any small changes tend to reduce the effectiveness of the system.
As capillary tube does not control the refrigerant flow in such systems is crucial in order to avoid damage to the compressor and to achieve maximum efficiency. Cleanliness of the system is also very important to avoid any obstacle in the capillary tube. Some large water chillers use a plate with a hole in exactly the same way. The same problems apply...
