<p>A heat exchanger (1A) having heat transfer tubes (2) disposed in multiple rows, wherein an exchanging heat quantity/air ventilating resistance are increased by suppressing an increase in air ventilating resistance without impairing the compactness of the heat exchanger, and a power consumption of an air conditioner is reduced to increase a cycle COP by increasing the exchanging heat quantity of the heat exchanger and bringing a relation between the heat exchanger and a blower in a good condition, heat transfer tubes (2) disposed in multiple rows have an outside diameter of 1 to 5 mm, each row of the heat transfer tubes (2) disposed in multiple rows is arranged in a staggered pattern, and two or more and five or less times as many heat transfer tubes (2) as the number of the rows are disposed in each row at a portion corresponding to each straight line of staggered broken lines.</p> |
