First Claim
1. An air conditioning system comprising:
- a heat pump unit including a radiator usable with a refrigerant;
a gas furnace unit including a heating section configured and arranged to heat passing air;
a blower configured and arranged to generate an air flow that passes through the radiator and the heating section; and
a controller configured and arranged to control each action of the heat pump unit, the gas furnace unit, and the blower, the controller being configured tooperate either the heat pump unit or the gas furnace unit as a heat source unit,generate a capacity command used to variably adjust operating capacity of the heat source unit, andexecute switch control in order to switch the heat source unit from either one of the heat pump unit or the gas furnace unit to the other based on an average value of an operating capacity level included in the capacity command outputted for a predetermined time.

Abstract
An air conditioning system includes a heat pump unit including a radiator usable with a refrigerant, a gas furnace unit including a heating section arranged to heat passing air, a blower arranged to generate an air flow that passes through the radiator and the heating section, and a controller configured to control each action of the heat pump unit, the gas furnace unit, and the blower. The controller operates either the heat pump unit or the gas furnace unit as a heat source unit, generates a capacity command used to variably adjust operating capacity of the heat source unit, and executes switch control in order to switch the heat source unit from either one of the heat pump unit or the gas furnace unit to the other when an operating capacity level designated in the capacity command is within a predetermined numerical range for a predetermined time.
