| description | The invention relates to a machine 1 comprising a treating chamber 2 for drying humid articles 3 by process air, a process air guide 5 for guiding the process air through the treating chamber 2 in a first circuit substantially closed in itself, and comprising a first blower 6 for driving the process air, a heat source 7 for heating the process air and placed upstream of said treating chamber 2, and a heat sink 8 for cooling the process air and placed downstream of said treating chamber 2. Heat source 7 and heat sink 8 are included in a heat pump 7, 8, 9, 10, 11 wherein the heat source 7 is provided for transferring heat from a refrigerant to the process air, and the heat sink 8 is provided for transferring heat from the process air to the refrigerant. The heat pump 7, 8, 9, 10, 11 further comprises a controllable compressor 9 for compressing and driving the refrigerant through the heat pump 7, 8, 9, 10, 11 for transferring heat from said heat sink 8 to said heat source 7, an expander 10 for expanding the refrigerant, and a refrigerant guide 11 for guiding the refrigerant through the heat pump 7, 8, 9, 10, 11 in a second circuit closed in itself, and an operating unit 12 for operating the process air guide 5 and the heat pump 7, 8, 9, 10, 11. The operating unit 12 includes a power sensor 13 for measuring a power input to operate said compressor 9, and a temperature sensor 14 for measuring a temperature of said refrigerant in a continuous part of said refrigerant guide 11, and is provided to operate said compressor 9 to perform at least one drying process for drying the humid articles 3. The drying process includes the following steps: (a) Initiating operation of said blower 6 to drive the process air through said process air guide 5, initiating operation of said compressor 9 to increase compressing and driving said refrigerant through said refrigerant guide 11; (b) measuring the power input, and measuring the temperature, and operating said compressor 9 at a power input equal to a respective predetermined power input provided that the temperature is lower than a respective predetermined temperature threshold, and operating said compressor 9 at a power input below said respective predetermined power input to keep the temperature at said respective predetermined temperature threshold, and continuing step (b) until the drying of said articles 3 is completed. The invention also relates to a set of drying processes. |
