CONDENSING TYPE CLOTHES DRYER HAVING A HEAT PUMP CYCLE AND A METHOD FOR CONTROLLING A CONDENSING TYPE CLOTHES DRYER HAVING A HEAT PUMP CYCLE

摘要

A condensing type clothes dryer having a heat pump cycle is provided that may include a drum in which an object to be dried may be accommodated; a circulation duct that forms a circulation passage such that air may circulate via the drum; and a heat pump cycle. The heat pump cycle may include a plurality of evaporators provided adjacent to each other in the circulation duct; a condenser provided at a downstream side of the plurality of evaporators and spaced therefrom, that absorbs heat of air discharged from the drum through the plurality of evaporators, and transfers the heat to air introduced into the drum through the condenser, using an operation fluid, which may circulate via the plurality of evaporators and the condenser; a plurality of divergence pipes that form a divergence passage, such that the operation fluid discharged from the condenser may be introduced into each of the plurality of evaporators; a plurality of electronic expansion valves provided at the plurality of divergence pipes, respectively, that opens and closes the plurality of divergence passage; and a controller that controls a flow amount of the operation fluid to be introduced into each of the plurality of evaporators by controlling an open degree of the divergence passage based on a super heat degree of the operation fluid passing through each of the plurality of evaporators.

1. A condensing type clothes dryer having a heat pump cycle, comprising:
a drum in which an object to be dried is accommodated; a circulation duct that forms a circulation passage that circulates air through the drum; and a heat pump cycle including:
a plurality of evaporators provided adjacent to each other in the circulation duct, that absorb heat of air discharged from the drum through the plurality of evaporators, using an operation fluid that circulates via the plurality of evaporators;a condenser provided at a downstream side of the plurality of evaporators and spaced from the plurality of evaporators, that transfers the heat to air introduced into the drum through the condenser, using an operation fluid that circulates via the condenser;a plurality of divergence pipes that form a divergence passage such that the operation fluid discharged from the condenser is introduced into each of the plurality of evaporators;a plurality of electronic expansion valves provided at the plurality of divergence pipes, that opens and closes the divergence passage; anda controller that controls a flow amount of the operation fluid introduced into each of the plurality of evaporators by controlling an open degree of the divergence passage based on a super heat degree of the operation fluid passing through each of the plurality of evaporators.
