The System Working Principle is：When stand-by station diesel-driven generator is run, generator in itself and produce flue gas will
Substantial amounts of used heat can be produced, now, heat source side loop water temperature gradually heats up, when waste heat is just equal with end heat demand
When, cooling side end heating equipment (such as Fresh air handling units+fan coil) is only opened, Waste Heat Reuse is realized；When surplus heat of power plant amount with
When end heating load is more or less the same or fluctuated up and down, while end heating equipment and the unnecessary heat of phase transformation reservoir storage are opened,
Make to realize that system thermal is balanced in system long period.When power station used heat is excessive and heat source side and cooling side water temperature persistently rise,
Open underground pipe and end heating equipment, the heat exchange and end-equipment heating by underground pipe and soil realize heat utilization and
Transfer.End heating equipment, phase transformation reservoir and underground pipe are parallel to circular water-loop, and underground protective engineering used heat is realized jointly
Cascade utilization and transfer.
Beneficial effects of the present invention are：Power station used heat is used for the heat supply of underground engineering end, turns waste into wealth, reduces boiler
Deng the use of firing equipment, the energy has been saved；The application of phase transformation reservoir in the present system, compared to traditional water tank, amount of stored heat is big
And can easily be accommodated, reservoir volume can be reduced, underground construction space is saved, construction cost is reduced.For unnecessary heat using ground
Pipe laying carries out cooling processing, not to ground discharge high-temperature flue gas, realizes the target of protection works infrared camouflage.Pass through the system
Application, surplus heat of power plant can be stored, converted and be comprehensively utilized, solve surplus heat of power plant discharge easily cause oral area exposure
Problem, can effectively improve the infrared stealth effect of protection works, improve power station Waste Heat Reuse efficiency.
