Abstract

PURPOSE:To increase the cooling rate of liquid refrigerant and to enhance air conditioning performance of an air conditioner, by making the diameter of a tube in the part on the side of refrigerant flowing out of a heat exchanger, which is functioned as a condensor in the refrigerating cycle of an air conditioner, smaller than the diameter of tubes in the other parts. CONSTITUTION:A heat exchanger 3 functioned as a condensor is composed of refrigerant pipings 4 and a number of fins 5 which are functioned as enlarged heat transferring surface, attached to the pipings 4, crossing at right angles with them. Gas refrigerant of high temperature and high pressure from a compressor is fed into a heat exchanger 3 from the piping on the inlet side, being condensed in the process of passing through refrigerant pipings 4, from and to 4a1-4a5, gradually radiating heat by exchanging heat with the air shown by an arrow mark 6. In this air conditioner, the cooling rate of refrigerant is more increased, by providing a slender tube part 4b to the side where ventilating air is taken into fins 5, connected to a piping 4a5, and by passing the refrigerant, condensed before coming up to the piping 4a5, through the tube part 4b. With such an arrangement, performance of the air conditioner can be improved.
