Why is pulse tube refrigeration called pulse tube refrigeration?
== ==
What has the author Steffen Herrmann written?
Steffen Herrmann has written: 'Measurements of the efficiency and refrigeration power of pulse-tube refrigerators' -- subject(s): Refrigeration and refrigerating machinery
What is pulse current?
pulse of current is produced at every burst of radiation ending geiger muller tube. when this radiation hits the argon atoms; present in the tube electrons are knocked off.
What are the pros and cons of a capillary tube in refrigeration?
Capillary tube is a very simple device and can be manufacture easily at low cost. The capillary tube can limit the maximum amount of refrigerant to be charged eliminating the need for a receiver in the refrigeration system. Another advantage is when the refrigeration plant is stopped, the pressure along the capillary tube and the entire system remains constant which means that if the compressor is restarted it does not need moreÊpower to overcome high pressure in the system. Hence, smaller compressors can be used instead of big, expensive ones. A disadvantage with capillary coil is that this system is non adjustable due to the fact that the control of the flow of pressure is dictated by the inside diameter of the tube.
What are components parts of refrigeration?
There are four main parts of refrigerator. A compressor A condenser A Metering Device(capillary tube) An Evaporator
4 major components of refrigeration and airconditioning?
Compressor, Condenser, Meter Device and Evaporator
Ton of refrigeration?
Tonne of refrigeration(TR) is the practical unit of refrigeration effect.Tonne of refrigeration(TR) is defined
Why discharge refrigeration gas admit to doom of a rotary refrigeration compressor?
The refrigeration system used in air conditioners with rotary compressor, the discharged gas is entered firstly into the doom of the compressor, while the system used with reciprocating and other compressors, it is admitted into the discharge tube. and are suction cooled. Why in rotary systems, the discharge refrigerant directly admit into the doom first.
When was refrigeration created?
Refrigeration was created in 1859
What is an example of refrigeration?
example of mechanical refrigeration
What is an example of mechanical refrigeration?

Why should we use pulse transformer rather than ordinary transformer?
Pulse transformers are designed to accurately reproduce signals with fast rise-times. They are not very good at reproducing normal sinusoidal AC signals. Pulse transformers are used to trigger SCR's, for instance, in motor controls and lamp dimmers. If you open up a photoflash unit, you will most likely see a small pulse transformer used to trigger the high-voltage pulse to the Xenon photoflash tube.
