In a process for operating a compression heat pump with evaporator, compressor (1), condenser (2) and hot liquid jet pump (4, 5) as a relief device for the condensed coolant, two hot liquid jet pumps (4, 5) which are intermittently charged with the condensate are provided, the two vapour-liquid mixtures produced are maintained at different pressures, the vapour fraction of the vapour-liquid mixture at the higher pressure is fed to the intake side of the compressor (1) and the vapour fraction of the vapour-liquid mixture at the lower pressure is fed to the hot liquid jet pump (5) at the higher pressure, the liquid fraction of the vapour-liquid mixture at the higher pressure is introduced into the liquid fraction of the vapour-liquid mixture at the lower pressure, the liquid fraction of the vapour-liquid mixture at the lower pressure is passed through an isenthalpic relief device to the evaporator and the vapour produced is conveyed to the hot liquid jet pump (4) at the lower pressure. |
