fourth embodiments are the examples each provided with only one condenser 34 but a plurality of condensers 34 may be provided in this case a plurality of condensers 34 may be connected with the circulation line 32 to form one heat pump cycle or a plurality of heat pump cycles may be formed as shown in fig5 the dehumidifying system shown in fig5 is provided with the condensers 34 respectively at the regenerating line 26 at the upstream side right side in fig5 and the diversion line 24 and is provided with two evaporators 36 and 36 at the supply air line 18 at the upstream side left side in fig5 while the evaporator 36 at the upstream side and the condenser 34 at the regenerating line 26 are connected with the circulation line 32 to construct a first heat pump 30 the evaporator 36 at the downstream side right side in fig5 and the condenser 34 at the diversion line 24 are connected with the circulation line 32 to construct a second heat pump 30 in the dehumidifying system constructed like this a cooling amount by the respective condensers 34 and 34 and a heating amount by the respective evaporators 36 and 36 can be individually controlled accordingly finer temperature control can be performed next a fifth embodiment of the dehumidifying system will be described the dehumidifying system of the fifth embodiment shown in fig6 is.
