Cryobiology: This is the study of life at low temperature. Cryobiology is that branch of biology which studies the effects of low temperatures on living things. Cryobiology science is the study of biological material & systems at below normal temperatures. Systems and materials which are studied in cryobiology can include cells,  proteins, organs, tissues and whole organisms. Temperatures can range from hypothermic temperatures to cryogenic temperatures. 

In other words we can say that cryobiology is generally a thought of the study of the effects of subfreezing temperatures on biological systems. The principles of cryobiology are universal to everywhere. The cryobiology covers all branches of low-temperature biology, containing the effects of temperatures above freezing.  In technically we can say that cryobiology is actually the study of living systems at any temperature which are below the standard physiological range.
