As soon as the intended operating temperatures have been reached, the heat exchanger 3 is switched on and the system now works in a stationary state.

  • the evaporation rate in the evaporator 2 and thus the condensation of the working medium in the condenser 12 can therefore be reduced.
  • the proportion of condensation in the heat exchanger 3 is thus greater, so that an increased heat output can be taken from it. If the performance of the cooling device 19 is sufficiently high, the valve 9 can optionally be completely closed and the condensation can be carried out entirely in the heat exchanger 3. For example, B. by the inventive method, the heat of condensation of cooling devices and cooling systems in the household can be used for the treatment of hot service water.
  • an injector 23 is arranged in the heating circuit 10. This has a similar regulating function to the mixing valve 15.
  • the injector 23 ensures that, depending on the temperature of the medium circuit, part of the heating circuit passes directly from the flow 21 into the return 22. This prevents excessive cooling of the medium circuit at low temperatures. The injector becomes ineffective at higher temperatures. The injector works automatically depending on the heating circuit temperature and does not require any external force to operate it.

Abstract

Par ce procede, on obtient de la chaleur pour le chauffage, au moyen de la compression, a haute temperature, d'un fluide de travail sous forme de vapeur. Le fluide est ainsi condense, detendu, vaporise et a nouveau comprime. La chaleur necessaire a la vaporisation du fluide detendu est prelevee totalement ou en partie du fluide comprime. Conformement au but, au moins une partie de la chaleur cedee lors de la condensation est utilisee pour la vaporisation du fluide de travail. On peut renoncer entierement ou en partie a l'utilisation de chaleur exterieure pour la vaporisation du fluide de travail.
