Hello,
what options are there to integrate a central ventilation system with heat recovery and a heat pump?
I would like to preheat the air supplied to the rooms in winter and precool it in summer.
I understand that the air exchange rate is not as high as with an air conditioning system, so the cooling effect in summer won’t be very strong. But maybe it could provide some support? When using the heat pump for cooling in summer, you can’t cool the underfloor heating too much (which is uncomfortable due to a warm head and cold feet) because of the dew point. However, if the air is precooled and some moisture is removed, you have fewer issues with the dew point.

These should then be able to communicate properly with the controlled residential ventilation system and the air-to-water heat pump. But only if done correctly.I’m not sure if they can actually communicate with each other. But we do have room thermostats. I would have assumed that if the room temperature is already higher in summer than what we set on the thermostat, the air-to-water heat pump shouldn’t be heating. The air conditioning units come with remote controls.
The air-to-water heat pump has a heating limit, so no communication is necessary.
For the controlled mechanical ventilation system, communication is required; otherwise, you end up pumping the warm air outside, while it is supposed to be cooled again through a heat exchanger.

Instead of 28°C (82°F) in the room, a more comfortable 24°C (75°F) would be preferable. This, of course, applies to all rooms.
But if there is absolutely nothing suitable available, that would obviously not be ideal.

There are suitable and elegant solutions for every task. Then there are difficult and special ones (not necessarily economical or sensible).
Cooling through controlled residential ventilation requires measures equivalent in value to a conventional air conditioning system. So why not just go for that right away?
