Abstract
A heating, ventilation, and/or air conditioning (HVAC) system has a first variable refrigerant flow outdoor unit, a first ducted variable speed indoor unit configured to selectively exchange refrigerant with the first variable refrigerant flow outdoor unit, and a second indoor unit configured to selectively exchange refrigerant with the first variable refrigerant flow outdoor unit.
Claims20
A heating, ventilation, and/or air conditioning (HVAC) system comprising:
- a variable refrigerant flow outdoor unit;
- a first variable speed indoor unit configured to selectively exchange refrigerant with the first variable refrigerant flow outdoor unit;
- a second variable speed indoor unit configured to selectively exchange refrigerant with the variable refrigerant flow outdoor unit;
- and
- a system controller configured to vary a speed of the first variable speed indoor unit, the second variable speed indoor unit, and the variable refrigerant flow outdoor unit,
- wherein the speed of the first variable speed indoor unit and the speed of the variable refrigerant flow outdoor unit are a function of a variation in speed of the second variable speed indoor unit.
A heating, ventilation, and/or air conditioning (HVAC) system comprising:
- a variable refrigerant flow outdoor unit;
- a first variable speed indoor unit configured to selectively exchange refrigerant with the first variable refrigerant flow outdoor unit;
- a second variable speed indoor unit configured to selectively exchange refrigerant with the variable refrigerant flow outdoor unit;
- and
- a system controller configured to vary a speed of the first variable speed indoor unit, the second variable speed indoor unit, and the variable refrigerant flow outdoor unit,
- wherein the speed of the first variable speed indoor unit, the speed of the second variable speed indoor unit, and the speed of the variable refrigerant flow outdoor unit are controlled independently and/or simultaneously to maintain a desired capacity and/or capacity ratio;
- wherein the speed of the first variable speed indoor unit and the speed of the variable refrigerant flow outdoor unit are a function of a variation in sped of the second variable speed indoor unit.
A method of operating a heating, ventilation, and/or air conditioning (HVAC) system, the method comprising:
- providing a variable refrigerant flow outdoor unit;
- providing a first variable speed indoor unit;
- providing a second variable speed indoor unit;
- operating the first and second variable speed indoor units to selectively exchange refrigerant with the variable refrigerant flow outdoor unit;
- providing a system controller;
- and
- varying, with the system controller, a speed of the first variable speed indoor unit and a speed of the variable refrigerant flow outdoor unit as a function of a variation in speed of the second variable speed indoor unit.
