Abstract
An air conditioning system includes a refrigerant circuit including a compressor, a condenser, an expander, and an evaporator, a first coolant line including a first heat exchanger and a first air conditioning heat exchanger, a second coolant line including a second heat exchanger, connected so that coolant in the first coolant line flows by connecting upstream and downstream ends of a second air conditioning heat exchanger to upstream and downstream ends of the first air conditioning heat exchanger, and a first valve selectively controlling the flow of coolant in the first coolant line on the upstream end of the first air conditioning heat exchanger, and a controller controlling the first valve in a heating mode so that coolant cooled by the first heat exchanger in the first coolant line flows to the first air conditioning heat exchanger and to the second air conditioning heat exchanger.
