VENTILATION SYSTEM WITH HYBRID HEAT SOURCE AND THE METHOD FOR CONTROLLING THE SAME

摘要

The present invention provides a compressed heat source unit including a compressor, a compression expansion valve, and a compression heat exchanger, and a compression heat source pump disposed on a compression heat exchange line flowing through the compression heat exchanger; Geothermal heat source having a geothermal line for heat exchange in the ground, a geothermal expansion valve disposed on the geothermal line, a geothermal pump and a geothermal heat exchanger, and a geothermal heat exchanger pump disposed on the geothermal heat exchange line through the geothermal heat exchanger Unit; A header configured to exchange heat with at least one of the compressed heat exchange line and the geothermal heat exchange line through a header working fluid; An air conditioning unit including an air conditioning blower; A sensor unit having a target temperature sensor for sensing a temperature of a target space, a header temperature sensor for sensing a temperature of the header working fluid, an external dry bulb temperature sensor for detecting dry and wet bulb temperatures of outside air, and an external wet bulb temperature sensor; A storage unit for storing a preset set dry bulb temperature, a set wet bulb temperature, a set header temperature, and a set target temperature value; And a control unit for comparing a sensing signal from the sensing unit with a storage value preset and stored in the storage unit to apply a control signal to the compressed heat exchange pump and the geothermal heat exchange pump. to provide.
