Definitions

  • heat pumps and chillers consists of a heat-absorbing (1) and a heat-emitting (2) heat exchanger, an energy-absorbing compressor unit (3) and a throttling or expanding device (4). They can be designed as cold gas or cold steam engines. This is shown in Fig. 1.
  • the claim relates to heat pumps and / or refrigeration machines with a steam process, which means that a material circulates in the system that occurs both in gaseous and liquid form.
  • the patent claim relates to heat pumps and / or refrigeration machines which are operated with a refrigerant with a zeotropic behavior. They are characterized in that condensation or evaporation do not take place at a certain temperature point, but at a sliding temperature (glide), that is to say in a temperature range.
  • Heat pumps and / or chillers according to the patent claim are additionally equipped with a suction gas-liquid gas heat exchanger (5), called an internal heat exchanger, and the sensor (6) of the expansion valve is arranged on the suction line in such a way that it is installed behind the internal heat exchanger instead of in front of it is.
  • This device is shown in FIG. 2. If there are several internal heat exchangers, the sensor (6) is placed between the last internal heat exchanger and the compressor.
  • FIG. 3 shows the pressure-enthalpy diagram (log p / h diagram) with the process without (dashed line) and with (solid line) of the device according to the patent claim.
