DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM

ABSTRACT
Cooling effect at one end of a hollow tube with a pulsating pressure in the inside gas, was first observed by Gifford and Longsworth in early sixties. This marks the inception of one of the most promising cryogenic refrigerators known as 'pulse tube refrigerator' (PTR). Cryogenics is the science of low temperature. Cryogenics refers to the entire phenomenon occurring below -150 C or 123K. Cryogenic engineering involves the design and development of system ....etc

DESIGN AND FABRICATION OF PLATE FREEZER
PROJECT REPORT

ABSTRACT
Techniques of freezing vary for each application, The type of refrigeration used for preserving fruits cannot suit the need of the fish industries. Later it has been discovered that the number of viable vegetative microorganisms in food are usually greatly reduced by freezing if quick freezing is employed. The conventional freezers could not cope with this higher rate of freezing. By the development of the plate freezer, the challenge of quick freezing ha ....etc

Abstract

The differential pressure method is widely used nowadays for air leak detection. In this method, a master tank, which is leak-tight, a tested tank are simultaneously charged to a certain pressure and then closed off each other. If there is air leak in the tested tank, the air leak can be detected from the different pressure occurs between the two tanks. Since both tanks temperature is inconsistent in detection process will lead to changes in pressure affect the detection precision. Although, if the tested tank is leak-tight. This ....etc
