Übersetzung für "Transcritical" in Deutsch

Advanced CO2 solutions designed for both transcritical and subcritical systems.

In the transcritical CO2-system, it is used in both low- and normal temperature cooling.

We already introduced in 2008 a heat recovery for transcritical CO2 refrigeration plants on Chillventa.

The new AK-PC 782A offers fully integrated pack control in transcritical CO2 booster packs.

Our experiences by building transcritical systems are applied consequently for further development of the market-ready concepts.

All the functions required for transcritical operation are integrated in the controller.

This is the first transcritical CO2 installation for distribution centers in Austria.

Heat recovery is made possible by the transcritical process management of the CO2 refrigerant.

At the moment the CO2/R134a-Cascade and the transcritical CO2-system lend themselves to being particularly energy-efficient cooling systems.

By comparison with a reference cooling circuit in heating circuits that are operated with a fluorine-hydrocarbon (R134a) as a medium in the circuit, the transcritical cooling circuit with CO 2 shows the same or better performance figures in a technically feasible temperature range of the heat source.

Transcritical cooling circuits are very good systems for applications in which a high temperature spread for giving off heat is advantageous and a heat source with nearly constant temperature is available.

CO2 is definitely an excellent choice as a transcritical option considering global warming potential, that being greenhouse gas emissions.

With the introduction of the 4PTC-6K model for lower displacements and the 4DTC-25K and 4CTC-30K models for higher displacements, the series for transcritical compressors now ranges from 4.3 to 25.6 cubic meters of displacement per hour at 50 Hz.

The transcritical CO2 rack Mini Booster, is suitable for medium and low temperature applications operating in small - medium supermarkets.

The air conditioner according to claim 2, characterized in that the refrigerant circuit has a transcritical or subcritical process guidance depending on the ambient temperature.

The method according to claim 12, characterized in that a transcritical or subcritical process guidance is executed depending on the ambient temperature.

EP 0 424 474 B1 describes a method and a device for operating a transcritical vapor compression circuit.

However, very different pressure ranges in refrigeration circuits have become increasingly common with the growing use of transcritical CO2 systems and necessitate more flexibility.

First place went to Jörg Nickl, who wrote his doctorate on "Development of an expander/compressor for the transcritical refrigeration process with carbon dioxide as refrigerant" at the Technical University of Dresden.

The coefficient of performance (COP) of transcritical refrigeration circuits with carbon dioxide can be improved by 20 percent by replacing the throttle valve with an expander.

The CO2 gas coolers named GGHC and GGVC have a maximum operating pressure of 120 bar and are thus ideally suited for subcritical as well as transcritical plant designs.

Nevertheless in this connection one should particularly talk about a temporary fashion, because especially the operation of the so-called transcritical CO2 systems is neither ecologically nor economically indefensible in the way these systems are now offered on the market.

First place went to Jörg Nickl, who wrote his doctorate on “Development of an expander/compressor for the transcritical refrigeration process with carbon dioxide as refrigerant” at the Technical University of Dresden.

In transcritical operation beyond the critical point, gas can no longer be liquefied by pressure and the relationship between temperature and pressure no longer exists.

The global objective of this subproject of the Transregio is to develop models and methods for the description of droplets and collectives of drops in external gas environments under transcritical and supercritical conditions.
