Title:
HEAT PUMP TYPE LAUNDRY DRYER AND METHOD OF DRYING LAUNDRY USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2014/187494
Kind Code:
A1
Abstract:
The present invention relates to a heat pump type laundry dryer (1) and a method of drying laundry with such a dryer. The heat pump type laundry dryer comprises a process air circuit (3) having a duct (4) for circulating process (5) through a laundry drum (2), a refrigerant circuit (6) having an evaporator (7), a compressor (8), a condenser (9), and an expansion valve (10) in serial connection for circulating a refrigerant, wherein the evaporator (7) and condenser (8) are arranged in heat exchange with the process air in the duct (4) for dehumidifying and subsequently heating the same, a first temperature sensor (11) arranged to measure a temperature (Tl) of the process air to be discharged into a drum (2) and a second temperature sensor (12) arranged to measure a temperature (T2) of the process air drawn out of the drum (2). The heat pump type laundry dryer is further provided with at least one additional temperature sensor (13), located at the refrigerant circuit (6), arranged to measure the temperature of the refrigerant (T3) and a control unit (14) adapted to dry the laundry to a target dryness by operating the process air circuit (3) and the refrigerant circuit (6) on the basis of the predetermined correlation between the temperatures (T1, T2, T3) and any abnormality of the temperatures (T1, T2, T3) measured by the first temperature sensor (11), the second temperature sensor (12), and the additional temperature sensor (13).
