ᐅ Heat Pump & Central Mechanical Ventilation System

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.

Why not install a proper air conditioning system?

It does not make economic sense.

If a heat pump can also provide cooling, why buy a separate air conditioning unit? That means double costs for purchase, installation, electricity, maintenance, and repairs.

You actually can’t, because the medium is wrong. An air conditioner is also a heat pump and does exactly what you expect. It doesn’t unnecessarily cool the water in the underfloor heating, but instead works where it’s needed—directly on the warm air, removing heat and moisture from it.

You still have those costs if you try to develop a hybrid system from two devices not intended for that purpose, which is supposed to take over the function. Without major structural changes and additional investments, your mechanical ventilation system with heat recovery remains just that, and your heat pump for water heating remains a heat pump for water heating.

But is it possible to connect an air conditioning system to an existing mechanical ventilation with heat recovery (MVHR) afterward, thus avoiding the installation of new indoor units and new supply lines? Are there MVHR systems that come prepared for this?
