Definitions
- heat pumps and chillers consist of one heat-absorbing (1) and a heat-emitting (2) heat exchanger, one 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 in Fig. 1st shown.
- a heat pump according to the preamble of claim 1 is e.g. out US-A-4 406 135.
- the claim relates to heat pumps and / or refrigeration machines with a steam process, the it means that a substance circulates in the system that is both gaseous and liquid.
- the claim relates to heat pumps and / or chillers, which with a refrigerant with a zeotropic behavior. You are through it characterized that condensation or evaporation is not at a certain Temperature point, but at a sliding temperature (glide), that means in one Temperature range.
- Heat pumps and / or chillers according to the claim are also included 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 instead of being installed in front of this internal heat exchanger.
- This device is in Fig. 2nd shown. If there are several internal heat exchangers, the sensor (6) is 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 claim.

Description
Claims (2)
- Wärmepumpe und/oder Kältemaschine nach dem Dampf-Kompressionsprinzip mit einem zeotropen Kältemittel, umfassend einen wärmeaufnehmenden Verdampfer (1), einen wärmeabgebenden Kondensator (2), ein mit einer Saugleitung versehenes Verdichteraggregat (3), ein Expansionsventil (4) und einen zusätzlichen, internen und mit dem Austritt des Verdampfers (1) verbundenen Gegenstrom-Wärmetauscher (5), wobei ein Fühler (6) des Expansionsventils (4) an der Saugleitung nach dem Ausgang des internen Gegenstrom-Wärmetauschers (5) niederdruckseitig angeordnet ist und wobei einerseits zur Fertigverdampfung (D->E) und Überhitzung (E->F) und andererseits zur Unterkühlung (A->B) des Kältemittels der Gegenstrom-Wärmetauscher (5) mit dem Austritt des Kondensators (2) und das Expansionsventil (4) mit dem Eintritt des Verdampfers (1) verbunden sind,
dadurch gekennzeichnet, dass im internen, als Koaxialwärmetauscher ausgebildeten Gegenstrom-Wärmetauscher (5) niederdruckseitig Mittel vorgesehen sind, die den am Eintritt mitgeführten Flüssigkeitsanteil in Kontakt mit der Wärmetauscherfläche bringen, wobei diese Mittel aus einem spiralförmig verwundenen Blechstreifen gebildet sind, der dem Massestrom einen Drall erteilt, um die schwereren Flüssigkeitstropfen im Flüssigkeitsdampfgemisch an die Wärmetauscherwand zu schleudern. - Wärmepumpe und/oder Kältemaschine nach Anspruch 1,
dadurch gekennzeichnet, dass bei Vorhandensein mehrerer Gegenstrom-Wärmetauscher (5) der Fühler (6) zwischen dem letzten internen Gegenstrom-Wärmetauscher (5) und dem Verdichteraggregat (3) angeordnet ist.
