Abstract
An air conditioning apparatus uses a heat medium containing at least one of cold water and hot water. The air conditioning apparatus includes: a heat source device; a heat exchanger configured to exchange heat between the heat medium and air; a flow rate control valve configured to control a flow rate at which the heat medium is supplied to the heat exchanger; a temperature sensor configured to detect a temperature of the heat medium discharged from the heat exchanger; and a failure determination unit configured to detect presence or absence of an abnormality in a flow path of the heat medium based on the temperature detected by the temperature sensor and a commanded degree of opening for the flow rate control valve.
