LOW ENERGY TYPE DRYING APPARATUS USING WASTE HEAT TO REDUCE ELECTRIC POWER CONSUMPTION THROUGH REUSING THE WASTED HEAT FROM THE CONDENSER OF A HEAT PUMP

摘要

PURPOSE: A low energy type drying apparatus using waste heat is provided to conduct the high temperature drying by using the high temperature air and low temperature drying by using the low temperature air through one drying apparatus.;CONSTITUTION: A low energy type drying apparatus using waste heat comprises a drying chamber(102), an air suction port, an air supply port, a high temperature heat exchanger(142), a low temperature heat exchanger(144), an intake multi directional valve(154), a high temperature blower(150), a low temperature blower(162), a high temperature exhaust multi directional valve(152), and a low temperature exhaust multi directional valve(158). The high temperature heat exchanger is contacted with the condenser of a heat pump and heat exchanged. The low temperature heat exchanger is contacted with the evaporator of a heat pump and heat exchanged. The intake multi directional valve is connected with the input sides of the high temperature heat exchanger and the low temperature heat exchanger selectively. The high temperature exhaust multi directional valve and the low temperature exhaust multi directional valve are connected with the high temperature blower and the low temperature blower respectively. The low temperature exhaust multi directional valve is connected with the input part of the high temperature heat exchanger and high temperature exhaust multi directional valve is connected with the air suction port.;COPYRIGHT KIPO 2012
