Air conditioning apparatus

摘要

An air conditioning apparatus includes a compressor, indoor and outdoor heat exchangers, an indoor fan, an expansion valve, a refrigerant-pressure-perceiving part, which perceives a pressure of refrigerant sent from the compressor to the indoor heat exchanger, and a control part, which performs startup fan control in which the indoor fan remains stopped until the compressor goes from being at rest to starting up and the pressure perceived reaches a high-pressure threshold. The control part repeats an action of reducing a flow rate of the indoor fan or stopping driving of the indoor fan when the pressure perceived is equal to or less than a low-pressure lower than the high-pressure threshold, and an action of increasing the flow rate of the indoor fan or initiating driving of the indoor fan when the pressure perceived reaches or exceeds a pressure threshold which is higher than the low-pressure threshold.

1. An air conditioning apparatus comprising:
a compressor; an indoor heat exchanger; an indoor fan; an expansion valve; an outdoor heat exchanger; a refrigerant-pressure-perceiving part arranged and configured to perceive pressure of refrigerant sent from the compressor to the indoor heat exchanger; and a control part configured to perform startup fan control in which
the control part controls the indoor fan to remain stopped until the compressor goes from being at rest to starting up and the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined high-pressure threshold,the control part thereafter drives the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds the predetermined high-pressure threshold, andthe control part thereafter repeats
an action of reducing a flow rate of the indoor fan or stopping driving of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part is equal to or less than a predetermined low-pressure threshold which is a lower value than the predetermined high-pressure threshold, andan action of increasing the flow rate of the indoor fan or initiating driving of the indoor fan when the pressure perceived by the refrigerant-pressure-perceiving part reaches or exceeds a predetermined pressure threshold which is a higher value than the predetermined low-pressure threshold and is a lower value than the predetermined high-pressure threshold.
