Abstract:
1. A dryer, comprising: a drying chamber for items to be dried; a supply air duct; a process air duct; an exhaust air duct; a heat pump with a heat sink and a heat source; a recirculating air duct to connect the supply air duct and the exhaust air duct by a mechanism in order to adjust a proportion of recirculating air and exhaust air in the dryer; a first sensor to determine a process air temperature; a controller to control the mechanism as a function of measured values of the first sensor; a comparator to compare an installation room temperature and an installation room humidity of air in an installation room to the process air temperature and a process air humidity of the process air in the dryer; and an assembly to at least partly open or close a first controllable closure facility and a second controllable closure facility of the mechanism as a function of at least one of a prespecified temperature difference between the process air temperature and the installation room temperature and a prespecified humidity of the air in the installation room.
