What is a narrow tube that is used as a metering device?
capillary tube
Would an orifice type expansion device perform much the same as a capillary tube metering device?
yes
What are components parts of refrigeration?
There are four main parts of refrigerator. A compressor A condenser A Metering Device(capillary tube) An Evaporator
Why is a capillary tube thought of as a dry-type?
The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.
What are the two types of metering devices?
capillary tube and fixed orifice
Explain the capillary tube type refrigerant control?
capillary tube are classified under fixed oriffes metering device it is thin and long inorder to control the refrigerant pressure and temperature not to evaporate ontheir way unitl it reach the evaporator.
Why the capillary tubing has a uniform bore?
As a metering device you need uniformity
What is a metering device on a refrigerator?
A metering device on a refrigerator is usually a capillary(cap)tube. It is a very small copper line located somewhere between the condenser coils (outside-hot) and the evaporator coils (cooling coils). It reduces the pressure of the refrigerant coming from outside as it enters the evap coils inside. Refrigerant cools under low pressure thus cooling desired inside area when air is blown across the cold coils. Think of a kinked garden hose and how on the spicket side of the hose the pressure is great, but on the other side the pressure is decreased. That is basically the purpose of a metering device.
Can an orifice in a steam line act as a steam pressure reducing valve?
Yes. But it is limited in control by the orifice size, pressure applied and piping diameter. In other words it is "fixed". An example would be the metering device in a refrigerant circuit, specifically an orifice or capillary tube. The same physics apply.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
What part of refrigeration system changes the high pressure side to the low pressure side?
There are two parts which do. The first is the compressor - the high side starts at the compressor outlet. The other is the metering device (either a Thermal Expansion Valve or a Fixed Orifice Tube). The high pressure high ends at the metering device inlet. The low pressure side starts at the metering device outlet and ends at the compressor inlet.
Why mercury falls in capillary tube?
because,the adhesive force of mercury in more compared to the cohesive force which acts on a capillary tube. that's why mercury falls in capillary tube
