Building A/C

So that you always keep a cool head
Our summers are getting hotter and hotter, and ensuring a comfortable indoor climate is just as important for office spaces as for production halls, hotels, or cinemas. Adsorption cooling systems from FAHRENHEIT generate the optimal temperature from waste heat. The heat can also be generated by cogeneration plants, from solar heat from the sun, or it can be directly obtained from production processes.
Our cooling systems help reduce your carbon footprint in many ways: They save up to 80% in electricity, they don’t use any artificial coolants and they work just with water.

Cooling—the smart way

Our chillers help your CO2 balance in two ways: They save up to 80% of electricity, and they do not require synthetic refrigerants—because they work with pure water.

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.

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.
