Thermal process model of tubes with phase-change substance in all-season electro-helium-water-heater
The considerable part of the hot-water necessities is forming by agricultural decentralized consumers may be provides by mean of using the solar water-heater sets. The phase-change substance influence determination on the dynamics of the heating and cooling processes was made. The results of investigations indicate that phase-change process increases the cooling time of the tube with paraffin to 30 0C from 14 minutes to 47 minutes, to 20 0C from 22 minutes to 66 minutes. That fart defines high heat-accumulating properties of the set.
