Abstract
An electronic expansion valve is provided that allows an air conditioner to control air conditioning in accordance with a valve opening point of the electronic expansion valve. Also, an air conditioner is provided that is capable of controlling air conditioning on the basis of the valve opening point of the electronic expansion valve. The electronic expansion valve is provided with a barcode corresponding to property data of the electronic expansion valve. The property data include a pulse number corresponding to a valve opening point that was measured in the process of manufacturing the electronic expansion valve. The valve opening point is set on the basis of the pulse number of a stepper motor when the flow rate of a gas flowing through a valve hole of the electronic expansion valve is equal to a set value.
