EcoCond – highly efficient system solution for cooling and heat recovery

EcoCond EcoCond+

The established system EcoCond has been upgraded to include a reversible heat pump in the hydraulic unit. In this way the system takes advantage of larger temperature differences between the air side and the heat transfer medium.

EcoCond is a high performance combined cycle system. The system essentially consists of counterflow-air-water heat exchangers in the supply and outlet air unit, a booster pump, hydraulic connections and an integrated control system. This system is particularly suitable for the separate installation of supply and outlet air units and in the event that a complete separation of the air flows is required.

EcoCond+ - the 3rd generation of cooling and heat recovery systems

The heat recovery system EcoCond+ is a new building block of BerlinerLuft.Klimatechnik GmbH‘s corporate stra-tegy to provide sustainable system solutions, which are characterised by maximum energy efficiency to reduce life-cycle costs. BerlinerLuft. Klimatechnik can draw on long-standing experience in refrigeration technology and with high performance combined cycle systems.

System concept

The new heat recovery system EcoCond+ is based on the principles of a high performance combined cycle system, combined with reversible heat pump technology. This system is particularly suitable for the separate installation of supply and outlet air units and in the event that a com-plete separation of the air flows is required.

In accordance with applicable regulations and legislation (DIN EN 308, VDI 6022, DIN EN 13053, energy conservation regulations and the German Renewable Energy Heat Act), the high performance heat recovery EcoCond+ represents a system which is characterised by high, above-average heat recovery levels.

The established system EcoCond has been upgraded to include a reversible heat pump in the hydraulic unit. In this way the system takes advantage of larger tempera-ture differences between the air side and the heat transfer medium.

The hydraulic unit of the EcoCond+ system combines the water-glycol mass flows (brine) from the supply air and outlet air heat exchangers in one compact unit with heat pump and in doing so, continually optimises the brine mass flow subject to the air mass flow and temperatures.

By additionally using a heat pump, an intelligent control strategy, in conjunction with a speed-regulated electrical control elements, heat recovery levels of greater than 80% can be achieved.

Taking an overall view of all the components, consisting of the AHU, high performance counter flow heat exchangers, hydraulic unit, heat pump and integrated ICA of BerlinerLuft.Klimatechnik GmbH, results in a control strategy that is optimally coordinated with the system components and thereby a highly efficient combined cycle system.

Capacity increase

Capacity increase (temperature difference) of an outlet air heat exchanger at 18,500 m3/h (according to standard condition p. 6)

Advantages of EcoCond+

- Greater temperature differences at the outlet air heat exchanger and therefore increase in the recovered capacities

- Smaller heat exchanger in the supply air and outlet air volu-me flow, therefore reduction in the air-side pressure losses

- Greatly reduced installation area for the air handling units- High coefficient of performance for the cooling machine in

heat pump and refrigeration mode- Low quantities of coolant, environmentally friendly coolant

with low global warming potential- Optimum adjustment of heat recovery to the annual

temperature profile- Little or no overcapacity in the event of low external air tem-

peratures, which have to be compensated for by switching on the frost protection to the outlet air heat exchanger, reducing its capacity -> only the heat pump is disabled

- More than 35% of the required electrical capacity of the heat pump is saved in fan capacity

- For about 80% of the annual operating hours, the tem-perature enables the electric capacity of the heat pump to be utilised directly as heat for the supply air conditioning

- Optimum adjustment and efficiency increase of the system at variable unit air quantities

Description:The EcoCond+ system is equipped with 2 heat exchangers in the supply air flow and 1 heat exchanger in the dischar-ge air flow, to meet the requirements of VDI 6022. The heat exchanger for preheating the external air before the

filter is designed to have just 3 pipe rows and a fin distance of 4 mm. This enables the specifications of VDI 6022 to be met in full. By using the heat pump, the flow temperature at the outlet air heat exchanger is reduced, which achieves an increase in capacity at the heat exchanger . The energy taken from the flow, including the electrical energy of the chiller, is fed back into the return flow of the outlet air heat exchanger.

Description:The EcoCond+ system is upgraded to include an addition-al plate heat exchanger in the flow of the supply air heat exchanger.

This feeds heat energy into the system to maintain the required flow temperatures in the water cycle. In this ope-rating condition the DDC control system automatically con-trols frost protection functions and the air-side anti-icing protection of the outlet air heat exchanger, sub-ject to air quantities and pressure losses. In the event of ice forming, the heat pump is switched off.

High performance heat recovery system EcoCond+with additional functions of adiabatic cooling and total refrigeration

Example of construction size 30 with 20000 m3/h, supply air temperature after heat recovery 17 °C

Adiabatic outlet air humidification:

Adiabatic outlet air humidification makes it possible to further increase the efficiency of the system in cooling mode. By using an adiabatic outlet air humidifier the inlet temperature of the outlet air heat exchanger can be great-ly reduced. The DDC control system calculates the inlet temperature in the outlet air heat exchangers, subject to the outlet air temperature and the outlet air humidity in conjunction with the efficiency of the humidifier. If the calculated difference between the inlet outlet air heat exchanger and the external air tempera ture reaches its target value, the humidifier is enabled. This ensures that the humidifier is not operated inefficient ly. Using an out-let air humidifier saves up to 40% of the external cooling energy in the factory con di tion.

Internal refrigeration:

Using this option the connection to the cold water supply can be entirely dispensed with. The EcoCond+ unit is upgraded to include an additional refrigeration section, which discharges condensation heat via the condenser installed in the outlet air unit. The PKW plate heat exchan-ger is replaced by a plate heat exchanger with direct evapo-ration. Decentralising the cooling supply (cooling by AHU) gives high reliability.

System concept


EcoCond is a high performance combined cycle system. The system essentially consists of counterflow-air-water heat exchangers in the supply and outlet air unit, a booster pump, hydraulic connections and an integrated control system. This system is particularly suitable for the separate installation of supply and outlet air units and in the event that a complete separation of the air flows is required.

In accordance with applicable regulations and legislation (DIN EN 308, VDI 6022, DIN EN 13053, energy conservation regulations and the German Renewable Energy Heat Act), the high performance heat recovery EcoCond represents a system which is characterised by particularly high heat recovery levels.

The hydraulic unit of the EcoCond system combines the water-glycol mass flows (brine) from the supply air and outlet air heat exchangers in one compact unit and in doing so, continually optimises the brine mass flow subject to the air mass flow and temperatures. By additionally using an intelligent control strategy in conjunction with a speed-regulated pump and electrical control elements, heat recovery levels of up to 75% can be achieved.

If required, heat energy can be added or withdrawn using plate heat exchangers. With these options the conventional reheating and recooling can be dispensed with in the AHU and the air-side resistances and installation areas reduced.

Taking an overall view of all the components, consisting of the AHU, high performance counter flow heat ex changers, hydraulic unit and integrated ICA of BerlinerLuft.Klimatechnik GmbH, results in a control strategy that is optimally coordinated with the system components and thereby a highly efficient combined cycle system.

High performance heat recovery system EcoCond with additional functions

Example construction size 30 at 20,000 m3/h

The upgrade versions of adiabatic outlet air humidification or dehumidification cooling recovery enables the efficiency of the system to be increased.

Adiabatic outlet air humidification:

By using an adiabatic outlet air humidifier the inlet tempe-rature of the outlet air heat exchanger can be greatly reduced. The DDC control system calculates the inlet temperature in the outlet air heat exchangers, sub-ject to the outlet air temperature and the outlet air humi-dity in conjunction with the efficiency of the humidifier. If the calculated difference between the inlet outlet air heat exchanger and the external air temperature reaches its target value, the humidifier is enabled. This ensures that the humidifier is not operated inefficiently. Using an out-let air humidifier saves up to 40% of the external cooling energy in the factory condition.

Dehumidification cooling recovery:

An additional supply air heat exchanger incorporated in the heat recovery cycle can replace the reheater in dehumidifi-cation mode. This circuit has 3 immediate benefits:- No external reheating in dehumidification mode, saving

100% PWW capacity- Decrease in the outlet temperature of the heat recovery

system before the recooler, thereby reducing the required cooling capacity (= saving PWW capacity)

- Increased efficiency of the heat recovery system in heat-ing mode as a result of additional heat exchanger area of the supply air heat exchanger
