摘要： PROBLEM TO BE SOLVED: To ensure an increase of discharged air power and an improvement of heating capability by disposing a rectifying heat exchanger on an air flow passage located between a cross flow fan and an indoor heat exchanger, and arranging fins of the rectifying heat exchanger substantially parallely to a blade of the cross flow fan. SOLUTION: Fins 7 disposed on a rectifying heat exchanger 9 are provided substantially parallely to a blade 1a of a cross flow fan 1. An air stream passing through an indoor heat exchanger 2 from a suction grill 6 owing to rotation of the cross flow fan 1 strikes the fins 7 whereby it is altered in its flow direction oppositely to the direction R of rotation of the cross flow fan 1 and is sucked. In this case, the fins 7 operate in the same manner as a centrifugal fan on the suction side of the cross flow fan 1 so that a sucked air amount is increased. Further, the rectifying heat exchanger 9 acts as a condenser upon heating operation so that a heat exchange area is increased. Hereby, there are ensured an increase of discharge air power and an improvement of heating capability.

摘要： PROBLEM TO BE SOLVED: To provide a heat source unit for an air conditioner capable of improving heating capacity by preventing frost formation on the outer surface of an outdoor heat exchanger.
SOLUTION: An outdoor unit 3 includes a body heat exchanger 33, first and second auxiliary heat exchangers 36a, 36b, a three-way valve 37, and a control part 39. The body heat exchanger 33 functions as an evaporator during heating operation. The first and second auxiliary heat exchangers 36a, 36b are connected to the body heat exchanger 33. The three-way valve 37 changes over through which the auxiliary heat exchangers 36a, 36b a refrigerant is made to flow in to the body heat exchanger 33. When frost is formed on the first auxiliary heat exchanger 36a to which the refrigerant is made to flow in, the control part 39 controls the three-way valve 37 so that a first state where the refrigerant is made to flow in to the body heat exchanger 33 via the first auxiliary heat exchanger 36a having frost formation is changed over to a second state where the refrigerant is made to flow in to the body heat exchanger 33 via the second auxiliary heat exchanger 36b without frost formation.
