PARALLEL FLOW TYPE HEAT EXCHANGER AND AIR CONDITIONER MOUNTED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a parallel flow type heat exchanger of side flow system in which the most preferable design in view of causing no drift current is applied to the number of flat tubes constituting a refrigerant path.SOLUTION: The parallel flow type heat exchanger 1 includes two vertical header pipes 2, 3 and a plurality of horizontal flat tubes 4 connecting the header pipes to each other. The plurality of horizontal flat tubes 4 are further grouped for the plurality of tubes and each of the groups constitutes a refrigerant path for flowing refrigerant from one of the vertical header pipes 2, 3 to the other. The upper limit of the number of flat tubes constituting one turn refrigerant path is defined by the following expression: n<3.0×10×Q+8.0(A)(when utilized in an outdoor unit) n<4.2×10×Q+7.9(A)(when utilized in an indoor unit).
