A plurality of refrigeration cycles that are capable of independently performing a heating operation and a defrosting operation, are provided. A ventilation damper of an indoor unit in which a refrigeration cycle that performs a defrosting operation is installed is closed during a defrosting operation, and a ventilation damper of an indoor unit in which a refrigeration cycle that performs a heating operation is installed is controlled to achieve a required amount of ventilation corresponding to the indoor ventilation state.

A plurality of refrigeration cycles independently performs a heating operation and a defrosting operation. By controlling a ventilation damper of an indoor unit that is to perform a defrosting operation to increase the amount of ventilation, a prior ventilation operation for securing the time-averaged required amount of ventilation including the period in which the defrosting operation is being performed is performed before the defrosting operation, and after the prior ventilation is terminated, the defrosting operation is started.

摘要： In a heat pump apparatus, switching between high efficiency operation, being efficient, and high capacity operation, having high capacity, is performed according to the state of the load. There are provided a main refrigerant circuit that uses an ejector, a first sub-refrigerant circuit that connects a portion between a heat exchanger and an ejector to a portion between a gas-liquid separator and a heat exchanger, and a second sub-refrigerant circuit that connects a portion between the heat exchanger and the ejector to an injection pipe of a compressor. When the load is about medium, refrigerant is circulated in the main refrigerant circuit to perform an efficient ejector aided operation utilizing the ejector. When the load is large, a high capacity injection operation is performed by flowing refrigerant to the second sub-refrigerant circuit. When the load is small, a simple bypass operation which prevents degradation of efficiency is performed by flowing refrigerant to the first sub-refrigerant circuit.
