Air conditioner
专利汇可以提供Air conditioner专利检索，专利查询，专利分析的服务。并且PURPOSE: To extract maximum capacity at each operation mode without fail by controlling an expansion valve based on temperature data from each temperature detecting means which is discriminated by a discriminating means.
CONSTITUTION: During heating operation, an expansion valve 5 is controlled based on an A/D transformation value of an input port part of an A/D input value included in each of zones II and III in chart (b). That is, the expansion valve 5 is controlled so that a difference of refrigerant temperature between a value detected by a first temperature sensor 10 provided at a first prescribed position and a value detected by a third temperature sensor 12 provided at a third prescribed position becomes a set value (superheating degree). On the other hand, during cooling operation, the expansion valve 5 is controlled based on the A/D transformation value of the input port part of the A/D input value included in each of the zones II or III in chart (a). That is, the expansion valve 5 is controlled so that a difference of refrigerant temperature between the value detected by the first temperature sensor 10 and a value detected by a second temperature sensor 11 provided at a second prescribed position becomes the set value (overheating degree).
