Heating bills in winter can be an unpleasant surprise. We try to insulate houses and install good windows, but we often forget about one important thing – ventilation. After all, by ventilating the room, we literally throw heat outside. What if this warmth can be returned?
This is exactly what recuperation was invented for, a technology that allows using the heat of the air removed from the room to heat fresh supply air. It sounds a bit scientific, but in fact it's a pretty elegant and effective solution to save energy.
How it works: the magic of heat transfer
The recuperation system is based on a special device – a recuperator. This is a heat exchanger through which two streams of air pass simultaneously: a warm exhaust from the room and a cold supply from the street. The streams do not mix, but heat is exchanged through the walls of the heat exchanger.
As a result, the cold air entering the house has time to warm up due to the heat of the outgoing air. In winter, this allows you to significantly reduce heating costs, since the system does not need to spend so much energy on heating icy outdoor air. In summer, by the way, the process works in the opposite direction – the recuperator helps to cool the hot supply air at the expense of the cool room air.
Types of recuperators: What should I choose?
There are several types of recuperators that differ in design and efficiency. The main ones are:
- Lamellar. The most common ones. They are a package of plates between which air flows. They are simple and reliable, but they can freeze at low temperatures.
- Rotary. A rotating drum (rotor) is used, which is alternately heated by exhaust air and gives heat to the supply air. They are more effective, they are not afraid of freezing, but they are more difficult and more expensive.
- With an intermediate coolant. Two separate heat exchangers connected by a circuit to a circulating liquid (for example, water with glycol). They allow you to separate the supply and exhaust installations.
The choice of a specific type depends on climatic conditions, budget, and ventilation system requirements.
The advantages are obvious: why is this necessary?
The main advantage of heat recovery is, of course, savings on heating (and air conditioning in summer). Cost reduction can reach 30-50%, and in some cases even more. This is not only beneficial for the wallet, but also environmentally friendly, as energy consumption is reduced.
In addition to saving money, the ventilation system with recuperation ensures a constant supply of fresh, filtered air without drafts and the need to open windows. This creates a healthier and more comfortable indoor climate, which is especially important for people with allergies or respiratory diseases. The air becomes cleaner and easier to breathe.
Not only the pros: what is worth thinking about?
Despite all the advantages, recovery systems have their own nuances. Firstly, it is the initial cost of purchasing and installing the equipment. They can be quite substantial, although they pay off over time due to savings.
Secondly, the recuperator, like any ventilation system, requires regular maintenance: cleaning filters, checking operability. And, of course, fans require electricity to operate, although its consumption is usually low compared to the savings on heating. In general, this is an investment that requires attention.
