How are Thermostatic Expansion valves and Electronic Expansion valves
It is a variable restriction type expansion valve. It maintains a constant degree of suction superheats at the evaporator outlet, therefore, it is also called a constant superheat expansion valve. The thermostatic expansion valve is probably the most widely used…
How are Applications of Refrigeration
The refrigeration applications may be grouped into the following categories: Domestic refrigeration Commercial refrigeration Industrial refrigeration Marine and transportation refrigeration Food refrigeration Preservation by refrigeration Comfort air-conditioning Industrial air-conditioning Preservation by refrigeration Freezing preservation: This is the most and most…
What are Lubricants in the refrigeration system?
The necessity of providing lubrication in refrigeration systems is to prevent frictional contact on metal surfaces in compressors and motor & fan bearings. Methods of lubrication: It varies depending upon the type and size of the compressor and the individual…
What is an Automatic Expansion valve?
It is a variable-restriction type expansion valve It maintains constant pressure in the evaporator, the so-called constant pressure expansion valve. A screen or strainer is usually installed at the liquid inlet of the valve in order to prevent the entrance…
What are Magnetic refrigeration systems?
Magnetic refrigeration was the first method developed for cooling below 2K. It is a low-temperature cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ranges used in common…
What is the Philips refrigerator?
The famous dutch Philips research laboratory developed experimental Stirling engines for a wide variety of applications and continued to work in the field until the late 1970s, but only achieved commercial success with the reversed Stirling engine. Philips constructed a…
What is the Cryogenic refrigeration system?
Cryogenics is the branches of physics and engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures Cryogenic refrigeration is a term that may be applied to the process of…
What is the working principle of an absorption refrigeration system?
Solar energy can be converted more efficiently to heat than mechanical or electrical energy, the use of vapor absorption cycle with solar energy to be the best solution at present time. It consists of the following collector: Solar flat plate…
What is an Electrolux refrigerator or Domestic absorption system
By adding a third fluid, an inert gas to the absorption system to balance the low – and high – side pressures of the system to function without a pump. Such system is called as three – absorption system. Thase…
