    When the COP of refrigerator is greater or less than 1?

    thanks for the explanation. So, it is mean that we can't compare COP of a system with the other system?

    When the COP of refrigerator is greater or less than 1?

    I found this when searching in other forum about COP. the forum discussed about COP of Vapour absorption refrigeration system. and somenone post a photo from this book "C.P. Arora “Refrigeration and air conditioning”" and the book says that "COP of 0,34 of vapour absorption system is equivalent...

    When the COP of refrigerator is greater or less than 1?

    so the different type of system have different standard of COP? is it mean if i have the COP of 0,2 of a vortex tube system is equivalent to COP of 2 Vapour Compression Refrigeration Systems?

    When the COP of refrigerator is greater or less than 1?

    VCRS is Vapour Compression Refrigeration Systems. So, if i have COP below 1, it means that the ability to remove heat is very bad?

    When the COP of refrigerator is greater or less than 1?

    I still confuse about COP of refrigerator. When i read some journal, it is said that COP of VCRS can be greater than 1 (usually 2 - 4). But, why the COP other than VCRS usally lower than 1? like vortex tube, vapour absorption refrigeration system, etc. Actually, now i am doing a research about...
