This year, the jury of the Highlights competition at the FinnBuild trade fair selected nine candidates to compete for the award for the fair’s most interesting innovation. Enervent Svea eAir E Cooler is included in the group. A ventilation unit designed and manufactured in Finland, which can have integrated compressor cooling, renews the cooling of homes.
After a four-year break, Finnbuild, a meeting place for construction industry operators, will take place at Helsinki Messukeskus in October. In the Highlights competition, the fair’s most interesting product, system and service is searched for. Enervent Svea eAir E Cooler is one of the nine selected.
The change in living requirements has increased interest in various cooling options in recent years. So far, there have only been a few options available for households. In addition to air source heat pumps, the traditional hybrid models that were previously on the market were primarily designed for commercial and office premises or restaurants. The Cooler unit developed by Enervent Zehnder to be integrated into the Svea ventilation unit brings a solution to the situation.
Svea’s Cooler unit meets customer needs
Thanks to the advanced fan technology, Svea corresponds to devices of larger size, but requires relatively little space. Despite its small size, the ventilation unit has both a rotating heat exchanger, an 800 W after heater and energy-efficient direct current fans. Enervent Svea was designed in such a way that a separate module can be placed on top of the ventilation unit. The module can contain a compressor cooling unit or, for example, water-circulating heating and cooling coils.
– Especially in new housing production, there has been a clear need for a unit that can integrate compressor cooling for a long time. Svea can be installed on the wall or ceiling. The Svea Cooler combination does not require larger space, but only increases the height of the device. The structure works like Lego blocks, and the Cooler can be retrofitted to previously purchased Svea devices, summarizes Ronni Laaksonen, who is responsible for sales at Enervent Zehnder.
The advantage of Svea Cooler is that the cooling is achieved without draft. The cooling is evenly distributed in all rooms with an supply air valve. This is a clear improvement compared to, for example, a traditional air source heat pump that only cools the space where the indoor unit is. Svea Cooler also does not need a separate outdoor unit.
Responsibility involved in development work
All of Enervent Zehnder’s product development is done at the company’s offices in Porvoo, Finland. In the same premises, there is also a climate laboratory that performs continuous testing.
– In our operations, we also want to consider the environmental impact of the company and our products. The new generation R32 refrigerant is used in Svea Cooler. It has a lower environmental load and lower climate effects than older refrigerants, Laaksonen confirms.
Deliveries of the Cooler module will begin this fall. The global shortage of raw materials has affected, among other things, deliveries of evaporator coils, which has slowed down the production schedule.
