<p>A heat pump type high-capacity air conditioning system is provided to use a control system of an existing air conditioner system having indoor and outdoor units of the same number without any change by introducing individual controllers per the indoor unit and an additional multiple controller. A heat pump type high-capacity air conditioning system includes an outdoor unit part, an indoor unit part, an air circulation part(30), and a multiple controller(40). The outdoor unit part has a plurality of outdoor unit elements(10A) for supplying and recovering heating medium by a heat pump driven by a driving source. The indoor unit part has a plurality of heat exchangers(21) connected to the outdoor unit elements by pipes, expansion valves(23) connecting the heat exchangers to the outdoor unit elements, air supply fans(25), and individual controllers(20A) for controlling the expansion valves. The air circulation part has an air outlet for supplying the air heat exchanged by the heat exchanger of the indoor unit part to a room(R). The multiple controller applies main signals to the individual controllers for controlling the outdoor unit elements in sequence according to a capacity corresponding to the temperature to raise or lower when set temperature becomes different from real room temperature sensed by temperature sensors of the room.</p> |
