With the EcoComfort, you fulfi ll the requirements of up to 100% of the latest German Government Regulations for Renewable Energy-Heating - Rules & Regulations (in German – Erneuerbare-Energien-Wärmegesetz (EEWärmeG)) regarding the utilization of environmental heat. Thereby, the system will be coupled with sev-eral module building blocks:

3

Direct heated unit:

The operation of the direct heated unit can be carried out on the basis of the highly sophisticated

NL-A-...NT, i.e the proven NL-A-technology by means of gas burner within condensing operations or

oil burner, respectively. Combustion chamber and shell-and-tube heat exchanger will be delivered, if

required, in complete stainless steel version, inclusive of condensate drainage system. Through this

process, efficiencies of 95 - 102% will be achieved.

Heat pump Module / - Components:

By means of the filter unit, the air will be pre-filtered. The heat exchanger then returns the heat back into the

air. This module can be also equipped to be operational in the cooling process - additional droplet separator

and condensate basin are upgrading the heat exchanger: Warmth in winter - Cooling in summer.

The production of heat is facilitated by the heat pump/(s) with inverter-technology. The positioning of such

facility can be carried out according to the actual requirements on site.

Control Cabinet:

The nordluft control system unit, with its individual solutions, makes an energy supply according to the needs

of the end user possible and therefore presents an optimal solution for energy utilization. Highly comfortable

equipment handling, due to the state-of-the-art ventilation control processors (VCP) together with a user-

friendly menu structure and easiest set point value adjustments, night-time cooling, energy selection, etc.,

make it a unique system.

Whether it is a Manufacturing Facility, a Public Swimmingpool or a Sportshall, Shops and Showrooms, Ware-

housing, or a Drying Plant - everywhere where direct heated warm air and ventilations systems are applicable,

our Eco-Systems guarantee law conforming, as well as energy-saving and economical systems for all kinds

of facilities.

EcoComfort - in Detail

Comfort withnordluft heat pumps

Warmth in Winter - Cooling in Summer

ECO-Heat pump

The nordluft heat pump module (System Mitsubishi) com-

bines warmth and cooling in one system. In winter, the air

will be comfortably pre-heated – in summer, the air can be

cooled down, optionally.

The heat pump - outside unit, with the state-of-the-art

performance controlled inverter-technology, produces

between 20 and 30% of the heat requirements. Accord-

ing to Facility size, 1, 2 or more outside units at 15, 20 or

25 kW heating output respectively, and at 15, 22 or

28 kW cooling output, will be combined into one unit.

The modulation range is from approximately 20 - 100%

(for heating operation).

Technical data - heat pump - outside unit (per piece):

Measurements (Length x Width x Height): approximately 1100 x 350 x 1,400 mm

Material casing: steel sheet, galvanized, lacquered

Material: heat exchanger: copper with mechanically bonded aluminium fi ns

Ventilator: direct mode operation of axial ventilator

Compressor: suction-cooled inverter scroll compressor

Data for the calculation of air inlet and air outlet temperature are to be implemented on a case by case basis.

The heat pump unit consists of one, i.e two heat pump out-

side units, the heat exchanger-fi lter module together with

the refrigeration engineering casing. The coolant serves as

heat / cooling carrier. The outside unit can optionally be

installed on the roof, onto the fassade, as well as adjacent

to the building. By means of fi lter unit G-4, the air will be

pre-fi ltered.

The heat exchanger with optional droplet separator and

condensate basin then returns the heat / cooling back into

the air: Warmth in Winter - Cooling in Summer

The WP-Outside Unit: State-of-the-Art

Performance controlled inverter-technology

of up to -15°C

Weight: approximately 150 kg

Heating output: 4 - maximum 25 kW

Cooling output: 12 - maximum 28 kW

Power supply: 3 x 400 V, 50 Hz

Wattage: approximately 7,29 kW

Transportation of working material to the heat exchanger (inside of the unit within the building) and output onto the

warming air within the Hall / Facility. The temperature of the used working material falls approximately to 25°C.

Expansion valve: Depressurizing of gas and return into its original condition (-30°C)

CoP (Coefficient of Performance):

Thermal efficiency of heat pumps and refrigeration units show the relation of the heating output (in kW) fed into to the

heating system, contrary to the absorbed electrical output of the heat pump (in kW). This rating represents a quality

criteria in regard to heat pumps. A CoP-rating of 4,1 means: out of 1 kW/ per hour, 4,1 kW/ per hour of heat is produced.

The determination of the CoP-rating is given according to defined conditions (for example: 10°C inlet air and 35°C exit air).

Working hours per year (WHPY):

This states the information about the electricity requirement of the entire Facility (with additional side-users like for example

pumps) and therefore represents the more important rating. This rating provides the relation of the yearly delivered heating en-

ergy in respect of the absorbed electrical energy. Economically and ecologically sound Facilities should have a WHPY of over 3,3.

Inverter - Technology:

Contrary to On/ Off systems (with constant rotation speed of the compressor), Inverter Facilities are regulated according to devia-

tion of temperature, i.e which means that the rotation speed of the compressor is higher or lower. The produced output varies.

Low energy consumption contrary to On/ Off Systems (up to 30%)

Low noise level

Commissioning of low energy supply possible

Constant remaining temperatures due to capacity regulation.

The coolant (R 410 A, with boiling point at -30°C)

in the WP-interconnecting system absorbs,

while fl owing through the heat exchanger, a

certain quantity of heat from the surroundings

(outdoor coil, outside the building). The tem-

perature of the heat transfer medium increases

by approximately 5°C .

Facility Concept:Coverage of heating requirements for a building

facilitated by 2 separate warm air heaters. The heat

pump (HP) alone as base load producer generates

the capacity up until a given fi xed outside tempera-

ture = tandem-operational set point. Upon reaching

this tandem-operational set point, the direct heated

warm air system (WAS) will be activated and the

heat requirement will be covered through both the

facilities.

nordluft offers its clients for the issuance of an energy

certificate (in German - Energieausweis) for production

facilities, as well as for commercial building require-

ments, by means of the calculations according to DIN

18599 namely, the ‘figawa hallen modul‘ calculations.

The calculations according to DIN V 18599: 2007-02 are incorporating the necessary updated and latest additions in the case of production facilities / com-

mercial building requirements.

Clearly arranged and user-friendly software with clear

and meaningful results.

The programme enables the easy variation of para-meters in regards to applicable terms and conditions such as geometrics, construction physics, as well as

plant engineering.

A comparison of central and de-centralized heating systems can be facilitated.

The latest edition and the actual used calculations in-

corporate the German energy-saving laws & regulations

(in German - Energieeinsparverordnung) of 2007 (EnEV

2007). Automatic update of EnEV 2009 took place after

ratifi cation of the afore-mentioned laws & regulations.

The programme was checked for conformity to DIN V

18599 and approved by the Institute for Technical Build-
