Abstract:

Heat pump is a kind of system, which can shift a lot of can’t direct use of low temperature heat energy into a useful device of high temperature heat at the price of a small amount of electricity consumption. Combining with the different forms of waste heat recovery with heat pump system design, use heat pump unit to extract the mine ventilation, drainage, air heat and other waste heat for building heating or air conditioning, so as to replace the coal-fired boiler, is a new energy-saving, environmental protection technology, has important significance to the construction of modern green new mines.

Key words: heat pump, Return air heat, Drainage heat, Heating, Air conditioning
