(7) FIG. 1 shows a perspective illustration of a thermotechnical system comprising a heat exchanger unit 10 which is formed with a vapor generator 11 and a condenser 12. The vapor generator 11 and the condenser 12 each have associated pipes 13, 14. On the heat exchanger unit 10, another heat exchanger unit 20 is arranged which is formed with a condenser 21 and a vapor generator 22. The two heat exchanger units 10, 20 form one refrigerating system.

(8) The vapor generator 11 and the condenser 12 are positioned in a frontal configuration or arrangement, wherein the front faces are arranged opposing each other. The same constructional layout is provided for the further heat exchanger unit 20 comprising the condenser 21 and the evaporator 22.

(9) Referring still to FIG. 1, and additional reference to FIG. 1A, during the operation of the refrigerating system, evaporated operating fluid, which is also designated as work fluid, flows from the vapor generator 11 to the condenser 12 in order to condensate there at least partially. The liquid condensate is then transferred to the vapor generator 22 in order to evaporate there and to subsequently flow as vapor to the condenser 21 where a condensation takes place again. The liquid generated here is then fed again to the vapor generator 11.
