PURPOSE:To increase the viscosity and make a heat accumulating material gel to eliminate the flowing property of the same by a method wherein the heat accumulating material is made by blending aliphatic compound, liquidous at a room temperature, with the proper amount of di-block type copolymer and tri-block type polymer. CONSTITUTION:High-temperature high-pressure gas, discharged out of a compressor 1, is introduced into an indoor heat exchanger 3 and is condensed to liquefy by effecting heat exchange between indoor air. Then, the liquid refrigerant is introduced into an outdoor heat exchanger to effect heat exchange after reducing the pressure thereof slightly upon passing it through an opening and closing valve 15 while the refrigerant is introduced into the second refrigerant pipeline 12 of a heat accumulator 5 through a three-way valve 17 to effect heat exchange between heat accumulating material 9 whereby the refrigerant is evaporated and gassified, then, is sucked into the compressor 1. Further, paraffinic heat accumulating material is mixed with the proper amount of di-block type copolymer and tri-block type polymer to obtain the heat accumulating material while the mixture is gelled to increase the viscosity of the same and is filled. In this case, the copolymer of styrene-ethylene-propylene can be used as the di-block type copolymer while the copolymer of styrene-isoplene-styrene can be used as the tri-block type copolymer. |
