Method and heat exchanger for heat recovery in a cooling installation which consists of a compressor, a condenser, an expansion valve, an evaporator in the cooling space, and, connected between the compressor and the condenser, a heat exchanger, in which a cooling medium circulates in the circuit, a partial condensation of the cooling medium by turbulence effect taking place in the heat exchanger, and the partial condensation of the cooling medium taking place by a turbulence and/or braking effect on the cooling medium which takes place a number of times. To this end, the heat exchanger consists of an inner tube (26) and an outer tube (27), indentations (28) being provided at spacings in the outer tube (27). The water to be heated flows in the inner tube (26) while the cooling medium flows in the outer tube (27) and can condense at the shell-shaped bulges caused by the indentations (28). <IMAGE> |
