First Claim
1. An air conditioning system comprising:
- a warm or cool air generating heat source unit, a capacity variable blower connected to the heat source unit, ducts in fluid communication with the blower to distribute warm or cool air, means for measuring air flow volume outputted by the air, generating heat source unit, means for measuring air flow noise of the air as it exits the ducts, a central thermostat having a plurality of operator controlled operational switches, and a control system which is operatively connected to the heat source unit, blower and central thermostat, the control system comprising;
a blower capacity setting means having an alpha-numeric display which, at initialization of the system, establishes an optimum capacity value by the operator actively interacting with the system by a question and answer dialog in native language format and entering signals through the operational switches on the central thermostat corresponding to a desired input to vary the capacity of the blower, the operator measuring the air flow volume and air flow noise until the optimum capacity value is reached and inputting said optimum capacity value through the operational switches on the thermostat;
a capacity memory means for storing the optimum capacity value which has been input by the capacity setting means as maximum value; and
a capacity control means which variably controls the operating capacity of the fan so as not to exceed the optimum value saved by the capacity memory means.

Abstract
A duct type air conditioning system with a variable capacity blower in which the maximum blower capacity is established at initialization of the system at the optimum blower capacity. The optimum capacity is established by varying the capacity of the blower and measuring the air flow volume and air flow noise. The optimum capacity is inputed into the control system through a central thermostat which has a liquid crystal display associated therewith. The system installer interfaces with the control system by a dialog which occurs through the liquid crystal display. The optimum capacity of the blower is stored in a memory device, and the control system variably controls the capacity of the blower so as not to exceed the optimum capacity.
