The Cool Art Remote Warmth Intelligently To Benefit

Combined Heat and Power: Making Optimal Use of Energy.
local heat is usually generated together with electricity (combined heat and power). The efficiency of this process is much higher than with conventional power plants. This makes district heating an efficient and resource-saving option for energy supply. Their use becomes even smarter when district heating is used to drive an adsorption refrigeration system. For one thing, the kilowatt price is usually well below that for electricity. On the other hand, district heating is available in excess in the summer months. But then just the cooling demand is greatest. Thus, the combination of district heating and adsorption refrigeration contributes to a meaningful, balanced and efficient use of our resources.

Also Suitable For Low Temperature Networks

District heating is also provided in part in modern low-temperature networks. Even then, the use of FAHRENHEIT cooling systems is possible. Because the units deliver good cooling results even at flow temperatures of 50 ° C and above.

GEOVOL

BUILDING COOLING WITH GEOTHERMAL ENERGY: GEOVOL UNTERFOEHRING 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

FERNWÄRME: IEP PULLACH GEOTHERMIE

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)

STADTWERKE HEIDELBERG I 550 KW

FILM-READY CLIMATE CONTROL SOLUTION: LUXOR FILMPALAST AND STADTWERKE HEIDELBERG

2017

The Luxor Filmpalast in Heidelberg is the world’s first Passive House cinema – and comprises 15 cinemas with 1,800 seats. Stadtwerke Heidelberg uses an adsorption refrigeration system from FAHRENHEIT for its air conditioning. The drive heat comes from a nearby wood-fired power plant.

Since the cooling energy is needed especially in the hot months, the system helps the municipal utilities to stabilize the base load of its power plants with combined heat and power. As a result, they can also generate more electricity from renewable energies in summer . Renewable energies win.
