3. Advanced simplicity of installation:
Meet the HRC! This abbreviation stands for “High Efficiency heat recovery Complete version”.
There also is a second model, which is called the HRV. This stands for the “Alternative” model. This alternative is equipped with the same Constant Flow motors and electronics as the HRC, but it does not have some of the “goodies” like by-pass, filter control et cetera.

4. Advanced simplicity of installation:
Easy wall mounting frame:
The right base to connect all the ducts
The HRC is made up of 3 major parts.
In the first place there is the wall mounting frame. This frame is important for many reasons:
It offers the right base to connect all the ducts

5. Advanced simplicity of installation:
Easy wall mounting frame
The right base to connect all the ducts
The body weights less than 25 kg, one man can do the job
Because of the spliced construction, the high-tech interior body can be fitted afterwards, this offers important advantages:
The body weighs less than 25kg, one man can do the job
The body is fully operational and therefore it can easily be tested outside the frame in case of technical service or maintenance

6. Advanced simplicity of installation:

Filter maintenance can be done easily thanks to the air sealed door.
A simple twist of the 2 screws unlocks the door.

34. Advanced higher comfort for the end user
Easily, with no air leak, filter maintenance:
1 door gives fully entrance.
Both filters are equal; they are mounted the othe way round. The filters have an extremely big surface, compared to some of the competitors. The advantage of this is important, since easier airflow requires less energy.

35. Advanced higher comfort for the end user
Easily, with no air leak, filter maintenance:
Optional to be changed by a pollen filter
The HRC can be equipped with a optional pollen filter. The opening is multifunctional and can be used for both filter types.

36. Advanced higher comfort for the end user
With only one 3 step switch optimal comfort:
Bio-rhythm
The HRC continually measures the aspirated outdoor air.
By doing this, the unit is able to detect tendencies.
The graph shows a random 24h temperature curve. Theoretically the coldest moment of day is situated somewhere in the early morning. Just pointing out this coldest moment would not do the trick in an accurate way.

37. Advanced higher comfort for the end user
With only one 3 step switch optimal comfort:
Bio-rhythm
By using some extra algorithms, the HRC is able to define the time up to +/- 1h accurately.
After 1 day the first results are ready and after 5 days it will take at least 3 consecutive days of identical wrong behaviour before the algorithm will start changing its internal time settings.
This biorhythm comes in very handy to adapt its decisions to its habitants, as we will see very soon...

Intelligent defrost cycle:
The intelligent de-ice scenario:
As we all know, the thermal exchange of warm and cold air generates some physical reactions.
Most of them do not generate a real inconvenience, only one of them does: ice!
The thermal exchange of warm and cold air generates some physical reactions

39. Advanced higher comfort for the end user
Intelligent defrost cycle:
Cold air causes condensate at the warm and humid side.
If we look at the basics of thermodynamics, we meet the forming of condensate in the heat exchanger. This is caused by the effect of warm humid air cooling down because of contact with the cold air from outside.
Because of this phenomenon the heat exchanger will generate condense water dripping out during certain combinations of temperature and humidity. There is a drain pan and condensate evacuation for this purpose mounted inside the unit.

40. Advanced higher comfort for the end user
Intelligent defrost cycle:
Extreme cold air causes frost at the exhaust of the warm humid air
If the outdoor temperature drops even further, the condensate water in certain areas will start freezing up as ice, blocking the way.
Ice will not damage the heat exchanger and some ice formation will not have a big effect on the results of the heat exchanger.
Nevertheless it is necessary to assure good ventilation, too much ice prevents this.

41. Advanced higher comfort for the end user
Intelligent defrost cycle:
A high humidity of the warm inside air decreases ice production.
If in certain conditions, the humidity of the indoor air rises, it is possible to push the ice forming out of the heat exchanger.
Humidity plays a very important role in the heat balance of the HRC.

42. Advanced higher comfort for the end user
Intelligent defrost cycle:
A low humidity of the warm inside air causes rime against the plates of the exchanger.
When the indoor humidity drops to a very low level, another phenomenon takes place: the indoor air is not humid enough to create ice that blocks the heat exchanger.

43. Advanced higher comfort for the end user
Intelligent defrost cycle:
Rime grow evolves much slower than ice grow
It is a slight rime formation that can continue for hours.

44. Advanced higher comfort for the end user
Intelligent defrost cycle:
If we resume, we come to the conclusion that some information is vital to understand what happens inside the heat exchanger:
Outdoor air temperature
Indoor air temperature
Indoor air humidity
Temperature of indoor air leaving the heat exchanger
By combining this information, it is possible to calculate the time needed before the heat exchanger has formed about 20% ice.

45. Advanced higher comfort for the end user
By combining this information, it is possible to calculate the time that is needed before the heat exchanger has formed about 20% ice.
If we then also use the biorhythm to estimate how far away the coldest point of day is, it is possible to get through the night without a de-ice cycle.
Practically the unit will use the leaving temperature of the heat exchanger to trigger the scenario, lower than +2°c starts the calculations. If the scenario started before 20h00 the unit will de-ice before night comes since the situation is more efficient.
In many cases the unit will defrost spontaneously when temperature rises again in the morning.

46. Advanced higher comfort for the end user
Intelligent defrost cycle:
Less defrost cycles = more comfort.
You might wonder if the negative energy cumulated in the ice isn’t more then what is won by continuing the airflow,
We ordered a study on this subject witch proves that even in the most bad situation (extreme ice formation) continuing is at least 8% more efficient then stopping one fan to defrost every time the leaving temperature goes beneath +2°C.
When rime is forming, this is always when indoor humidity is low, mainly because outside temperature is low. The temperature of the leaving air will be extremely low, in other words: the unit is at its best, don’t stop it.
If the outdoor temperature stays negative for more then 5 days, the unit will organise a defrost anyway during 1 h, around 15h00 in the afternoon since that is most lightly the warmest moment outside in winter.

47. Advanced higher comfort for the end user
Intelligent defrost cycle:
Thanks to the bio-rhythm no improper actions: the unit recognizes day and night and takes the right decisions.
Defrost cycles will maximal be forwarded or delayed during the night.
Thanks to the biorhythm the unit will recognise night.
Defrost cycles are being moved as much as possible earlier or later then night.

48. Advanced higher comfort for the end user
Proportional bypass:
Fully automatic = more comfort
The HRC is equipped with a proportional by-pass.
During the summer it is unpleasant to have the fresher night air coming in heated up by the warmer inside air leaving the house. Therefore the unit will check if this situation is present. If so the valve will be opened and takes away one of both airflow's of the heat exchanger. As a result of this, no air will be warmed up.
Two conditions have to be fulfilled:
Leaving air from the house must be higher than 23°C

49. Advanced higher comfort for the end user
Proportional bypass:
Fully automatic = more comfort
During daytime, temperature has to be +18°C or more for at least 8h

50. Advanced higher comfort for the end user
When the valve is opened, the temperature will be regulated as close as possible to +14°C. If lower: the valve closes step by step (per 3%).
