A refrigerating system and control method are provided to be able to improve the efficiency of the refrigerating system by presenting the decision criteria of the new cooling driving conversion period when the cooling driving is successively converted for the cooling of the cooling space. A refrigerating system comprises as follows. An plurality of evaporators(110, 120) equips in each of a plurality of cooling spaces supplied with the refrigerant discharged in the compressor(140). The refrigerant supply means(170) selectively supplies refrigerant among a plurality of evaporators to one. Using the refrigerant supply means, the temperature sensor(114a, 114b, 124a, 124b) senses the temperature of inflow and discharge air to the evaporator supplied with refrigerant. Based on the sensed temperature as described above, the control unit controls the operation of compressor or the refrigerant supply means. The refrigerant supply means is three way valve. The temperature sensor is installed at inflow and discharge location from the evaporator. |
