ELECTRONIC EXPANSION VALVE AND AIR CONDITIONER PROVIDED WITH ELECTRONIC EXPANSION VALVE

摘要

Provided are an electronic expansion valve (30) making it possible for an air conditioner (1) to control air conditioning in accordance with the valve opening point of the electronic expansion valve (30), and an air conditioner (1) able to control air conditioning on the basis of the valve opening point of the electronic expansion valve (30). Imparted to the electronic expansion valve (30) is a barcode (63) corresponding to property data of the electronic expansion valve (30). 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 (30). The valve opening point is set on the basis of the pulse number of a stepping motor (50) when the flow rate of a gas flowing through a valve hole (34) of the electronic expansion valve (30) is equal to a set value.
