Abstract
In an air conditioner, a controller calculates a value of a pressure of a refrigerant when the refrigerant is a saturated liquid at a value of a temperature measured by a second sensor, calculates, based on a value of a pressure or a temperature measured by a third sensor, a value of a pressure at an outlet of an expansion valve, calculates a difference dP1 between a value of a pressure measured by a first sensor and the calculated value of the pressure of the saturated liquid and a difference dP2 between the calculated value of the pressure of the saturated liquid and the value of the pressure at the outlet of the expansion valve, and adjusts, based on a proportion of the calculated difference dP2 to the calculated difference dP1, a degree of opening of the expansion valve.
