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 <sup>0</sup>C from 14 minutes to 47 minutes, to 20 <sup>0</sup>C from 22 minutes to 66 minutes. That fart defines high heat-accumulating properties of the set.
