HYBRID HEATING SYSTEM INCLUDING HEAT EXCHANGE TANK USING WASTE HEAT AND HEATING METHOD USING SAME

摘要

The present invention relates to a hybrid heating system including a heat exchange tank using waste heat, capable of improving thermal efficiency, and a heating method using the same. According to one embodiment of the present invention, the hybrid heating system including a heat exchange tank using waste heat comprises a heat pump and the heat exchange tank. The heat pump comprises: a compressor to convert a refrigerant gas into a high temperature and high pressure state; a four-way valve to change the direction of the refrigerant gas passing through the compressor; a condenser which is a first heat exchanger of a cell and tube type, liquefying the refrigerant gas through heat exchange reaction between the refrigerant gas passing through the four-way valve and waste heat of an air conditioner or a refrigerator, and receiving the refrigerant gas from a tube area and receiving reaction water from a cell area to receive heat from liquefaction of the refrigerant gas and a waste heat supply source so as to be heated; an expansion valve to throttle the refrigerant liquefied while passing through the condenser; and an evaporator which is a second heat exchanger to evaporate the refrigerant passing through the expansion valve. The heat exchange tank comprises: an inlet to supply the reaction water heated by the heat exchange reaction through the first heat exchanger, which receives the waste heat in the heat pump; a baffle alternately disposed in a zigzag shape to allow the reaction water passing through the inlet to maintain a vortex flow and including a through-hole; a heater rod to penetrate the through-hole formed in the baffle; a power connection means to supply power to the heater rod; and a process fluid flow path heated by resistance through the power connection means to increase the temperature of the reaction water. Moreover, the reaction water passing through the heat exchange tank is circulated to the heat pump again.;COPYRIGHT KIPO 2018
