Title:
PULSE ELECTROTHERMAL AND HEAT-STORAGE ICE DETACHMENT APPARATUS AND METHODS
Document Type and Number:
WIPO Patent Application WO2006081180
Kind Code:
A3
Abstract:
Systems and methods for pulse electrothermal and heat-storage ice detachment. A pulse electrothermal ice detachment apparatus includes one or more coolant tubes (4) , and optionally, fins (2) in thermal contact with the coolant tubes. The tubes and/or fins form a resistive heater (10) . One or more switches (12) may apply electrical power to the resistive heater, generating heat to detach ice from the tubes and/or the fins. A freezer unit (400) forms a heat-storage icemaking system having a compressor (410) and a condenser (420) for dissipating waste heat, and coolant that circulates through the compressor, the condenser and a coolant tube (430) . The coolant tube is in thermal contact with an evaporator plate (435) . A tank (440), after the compressor and before the condenser, transfers heat from the coolant to a heating liquid (445) . The heating liquid periodically flows through a heating tube in thermal contact with the evaporator plate, detaching ice from the evaporator plate.
