Übersetzung für "Compression chiller" in Deutsch

District Cooling can make usage ofalternativesto conventional electricitycooling from a compression chiller.

In order to support the cooling and contrary to the original concept, a compression chiller was integrated into the system, whose heat exchanger can also be used for free cooling.

When cooling the grinding machine, the decentralised compression chiller was replaced by a newly developed heat exchange module that is integrated into the factory's central cooling network.

Compression chillers commonly used to cool down buildings are responsible for a high electricity demand.

As reference, the researchers investigated scenarios with conventional compression chillers.

Solar thermal cooling competes with systems with conventional or solar electric driven compression chillers.

Thanks to the falling cost of photovoltaic energy, solar-electric cooling with compression chillers is becoming increasingly attractive.

The significant decrease in the cost of photovoltaics has also made solar electricity systems with vapour compression chillers increasingly attractive.

Energy maybe supplied by fossil fuel or a biomass boiler, solar thermal collectors, a heat pump,cooling systems (thermally driven or compression chillers) or from a combined heat and power plant (CHP).

In Giessen, a wide ranging thermal energy supply is ensured by using waste heat from the exhaust gas and cooling water from the CHP modules, as well as by using the absorption and compression chillers for cooling.

Thus, for example, just a few characteristic values (the cost of electricity and heat, daily hot water demand and daily electricity consumption for cooling) can be used to estimate how the heat recovery from vapour compression chillers can be optimally operated.

For cooling, you prefer cold ambient air, groundwater, marine water, efficient compression chillers and absorption chillers.

The operation of the three CHP modules, the absorption chiller, two compression chillers and a district heat transfer station in parallel to the cooling and district heating networks was tested during the first complete operating year.

If the heat requirement exceeds the output of the CHP systems, the absorption chillers are stopped and the compression chillers cover the remaining cooling demand.

At the same time, the cooling load can be generated either by compression chillers using electricity or by an absorption chiller using CHP waste heat.

The use of waste heat from the exhaust gas and cooling water from gas engines, the incorporation of high-temperature heat from the fuel cell unit as well as cooling using absorption and vapour compression chillers provides a wide range of thermal energy that is utilised in combination with combined heat and power generation.

The researchers achieved this by optimising the supply structure: Compression and absorption chillers, CHPs and boilers, connected to the public power and gas network.

Compared to the real life system structure, the optimal system with two integrated CHPs saves 40 % of the costs of procurement and investment over a ten-year period.The researchers achieved this by optimising the supply structure: Compression and absorption chillers, CHPs and boilers, connected to the public power and gas network.
