Filed: 1995-06-30
Abstract: PURPOSE: To obtain a heat storage material having an arbitrary freezing point without decreasing the quantity of heat stored in the range of temperature at which heat is stored by mixing an n-paraffin with an α-olefin having the same number of carbon atoms. CONSTITUTION: An n-paraffin (e.g. 16 C n-paraffin) is mixed with an α-olefin (e.g. 16 C α-olefin) having the same number of carbon atoms in a selected mixing ratio to obtain a heat storage material having a freezing point = crystallization peak temperature ( deg.), a melting point = melting peak temperature ( deg.C) and the quantity of stored heat (freezing point) = heat of crystallization (mJ/mg) when measured by differential scanning calorimetry(DSC) conducted in consideration of the freezing point (melting point) appropriate to the object and the use. When the mixing ratio is 50:50 by weight, a storage material having a freezing point of 5.1 deg.C, a melting point of 11.2 deg. and the quantity of stored heat of 155mJ/mg is obtained.  Because no transition point exists, a decrease in the quantity of stored heat and the extension of the range of heat storage temperature otherwise resulting from the formation of a solid phase transition point are prevented.
