HEAT QUANTITY CALCULATION METHOD FOR BRINE-REFRIGERANT TYPE HEAT PUMP SYSTEM USING GEOTHERMAL ENERGY

摘要

In a brine-refrigerant type heat pump system using geothermal energy according to the present invention, a heat quantity generated from a heat source side using brine is calculated and a heat quantity consumed in a demand side is calculated through the heat quantity generated from the heat source side. Therefore, the heat pump system does not need to use an expensive refrigerant flow meter and the like in order to calculate a heat quantity in a demand side using a refrigerant, and thus has an advantage reducing costs. Also, the heat pump system controls an on or off times of a brine pump and a heat pump differently and calculates the generated heat quantity in the heat source side so as to add same while the brine pump is on, and thus can more accurately calculate a heat quantity.
