Abstract: There is provided a freezing and cooling system as well as a condensing heat exchanger device capable of reducing in size of a condensing heat exchanger device, promoting a cost reduction of the device in a freezing and cooling system as well as energy saving and promoting to keep a global environment, wherein a freezing cycle is formed such that condensing gaseous refrigerant of high temperature and high pressure discharged from a compressor 1 is divided to flow, the over-half amount of condensing gaseous refrigerant is sent into an inner box 6 of a condenser 5 comprised of a double-box type heat exchanger of the inner box 6 and an outer box 7 enclosing the inner box 6, a residual amount of condensing gaseous refrigerant is sent to a capillary coil 8 acting as to increase flowing speed of refrigerant flowing in it, liquid refrigerant of low temperature and low pressure attained through condensing, reducing pressure and expanding at the capillary coil 8 is sent to the outer box 7 of the condenser 5 so as to p
