It Cooling With Minimal Power Consumption
The summers are getting hotter, and a pleasant indoor climate is important for offices as well as for production halls, hotels or cinemas. FAHRENHEIT adsorption refrigeration systems produce the optimum temperature from waste heat. The heat can be generated for example from cogeneration plants, generated by solar thermal energy from the sun or obtained directly from the waste heat of production processes.
Our units help you to reduce your carbon footprint in many ways: you save up to 80% on electricity and you do not need synthetic refrigerants and work exclusively with pure water. As part of the National Climate Initiative, energy-efficient refrigeration and air conditioning systems are also funded by the Federal Government.

Drive Through Waste Heat Of The Cpus.

It is particularly energy-efficient to use the waste heat from the cores themselves for cooling. This variant is particularly suitable for water-cooled systems.

Drive by external heat.

Low power consumption, positive environmental aspects: In economic and energy policy, the use of cogeneration units is particularly interesting. District heating is also suitable for driving our cooling systems. This variant makes sense from approx. 5 kW cooling demand

ANTONIYKA SCHOOL

SOLAR POWERED COOLING: ANTONIYKA SCHOOL, UKRAINE

2016

Advanced cooling for model school in Ukraine.

The showcase project was co-organized with Sovasolar Ltd. developed, planned and successfully implemented with an eCoo 2.0 I 30 IPS adsorption machine. The entire school was prefabricated in Finland and delivered to Ukraine by Elemento Oy.

Outside the cooling period, a solar system generates energy for water heating and space heating, while the three modules of the adsorption chiller cool the building via modern recirculation units in the hot summer. The FAHRENHEIT adsorption chillers are powered by the solar system.

DEUTSCHES PATENTAMT MÜNCHEN

Solar cooling: German Patent Office Munich

2011

Future-oriented adsorption technology for the German Patent Office Munich. In 2011, a geothermal system coupled with solar energy generation was technically and optically integrated into the monument-protected building in flat roof construction during the remedial and energetic refurbishment of the DPMA in Munich.

FAHRENHEIT has been entrusted with using solar heat through four highly efficient and energy-efficient adsorption systems for building cooling during the summer months. Thanks to the combined use of geothermal energy and solar energy, 60% of the energy demand in the main building of the DPMA in Munich will be covered by renewable energy.

GEOVOL

BUILDING COOLING WITH GEOTHERMAL ENERGY: GEOVOL UNTERFÖHRING GMBH

2014

The Bavarian geothermal plant operator Geovol decided in 2014 to install a FAHRENHEIT adsorption refrigeration plant, which is operated with district heating of approx. 90 ° C, as part of the planning of its new energy center at the Unterföhring site.

Since December 2015, four eCoo 2.0 adsorption chiller units have been cooling the offices, technical rooms and a conference room in the two energy centers all year round. In addition to the maximum cooling of the "in-house" district heating, the aim was also to further improve the energy efficiency of the already green technology. With the support of the Leipzig planning office, green-engineers, Geovol was able to achieve this with great success.

The buildings are completely and reliably supplied with sorptively generated refrigeration completely and reliably by the FAHRENHEIT generators without any conventional compression refrigeration technology.

This enables Geovol to reduce the consumption of electrical energy by approx. 31 MWh / a. According to projections, the use of adsorption refrigeration also saves 12 tonnes of CO2 per year.

IEP PULLACH

DISTRICT HEATING: IEP PULLACH GEOTHERMAL ENERGY

2015

The IEP (Innovative Energy for the Pullach GmbH) is a 100 percent subsidiary of the community Pullach in the Isar Valley. In cooperation with FAHRENHEIT, the head office of DJE Kapital AG has been realized with a highly efficient adsorption cooling system eCoo 2.0 for cooling the server room and the office space above the floor in the cold contracting process.

In addition to the perfectly calculable costs of cooling by billing per kWh without capital commitment and maintenance costs, the environmental aspects were also decisive for asset managers. The CO2-neutral heating and cooling system not only serves your own green conscience, but also shows to the outside that sustainability is important to the company in several respects. This is not always the cheapest, but overall very well the cheapest solution.

The new building and the expansion of the DJE Kapital AG headquarters are now up and running, and a new edition of the adsorption technology from FAHRENHEIT has been chosen. (Implementation 2019/2020)

FASA AG

ROOM COOLING WITH SOLAR THERMAL ENERGY: FASA AG

2018

“FASA AG is considered one of the pioneers of solar construction in Germany. With the construction of a new company headquarters in Chemnitz in 2011, with the ENERGETIKhaus® principle, an active sun office building was developed that almost exclusively (more than 90%) covers its energy requirements for heating and hot water via the sun. In 2019, the plant technology was extended by a cooling system. When cooling for the summer months, FASA AG chose FAHRENHEIT for the expert in sustainable adsorption cooling from Halle an der Saale.

For the air conditioning of the offices, the heat of the in-house solar thermal system (solar large storage tank with 110 m³ volume) was used, which delivers exactly the right temperature of 80 to 90 ° C for the operation of the adsorption refrigeration system FAHRENHEIT. Thus, the room cooling is made possible by the eCoo 2.0 I 10 with almost no electricity and CO2 neutral. “

SPARKASSE PASSAU

CHP: SPARKASSE PASSAU

2018

Sustainable energy savings with FAHRENHEIT and Sparkasse Passau.

Sparkasse Passau relies on the ecological handling of environmental and energy resources and therefore uses a combined heat and power plant plus environment-friendly cooling systems from FAHRENHEIT. The CHP provides 50kW of electrical power and 85.0kW of thermal power in a very compact CHP, just 1.7sqm of floor space, and powered by environmentally friendly gas.

In times of low-interest rates, as the responsible project manager explained, investing in energy and cost-saving technology is an even smarter investment.

A simple idea, because the power generation works with simultaneous heat dissipation and heat consumption. Good in winter, but also beneficial in summer. Then the generated heat of the CHP is converted with an adsorption chiller of FAHRENHEIT into cold, the u. a. the room air conditioning over the existing ventilation system is used.

The advantage of the new adsorption chiller is the high electrical efficiency with a cooling capacity of more than 40 kW!

This not only benefits Sparkasse Passau with a significant reduction of its electricity consumption for cooling by almost 60%, but also the climate in the city.

2016

The specialist for rubber floor coverings is a leading manufacturer, which relies on sustainable raw materials and environmentally friendly production: high-quality raw materials, especially old car tires, are optimally recycled through ingenious manufacturing processes.

There is hardly any waste in the production of KRAIBURG rubber flooring. Das Verfahren erlaubt es, Verschnitt von maßgeschneiderten Produkten wieder in den Wertstoffkreislauf aufzunehmen. Another important contribution was made in 2016, together with FAHRENHEIT, namely the saving of electricity and the reduction of CO2 emissions.

Die FAHRENHEIT – Adsorptionskälteanlage hat die Aufgabe, einen Schalt- und Serverraum mit 72 kW Abwärme aus dem Kondensat eines Dampfprozesses möglichst effizient zu kühlen. Realisiert wurde eine hocheffiziente Adsorptionsanlage eCoo 2.0|30 IPS, welche die Temperatur im Schaltraum mit 37 kW Kühlleistung konstant auf 18° C absenkt.
