HEAT RECOVERY UNIT NILAN Combi302 S polar
The Combi S 302 Polar Top combines two heat recovery technologies.
Passive recovery operates via a counterflow heat exchanger that recovers 85–95% of the energy from exhaust air. Active recovery using a heat pump captures the remaining energy left by the passive system. The heat pump has a COP of over 4, and due to the heat pump, additional post-heating is rarely required. The Combi 302 unit can heat supply air to well over 30 degrees Celsius.
With the heat pump, supply air can be cooled in summer by over 10 degrees. Due to the air exchange rate, this does not fully replace an air conditioning unit, but cooling the supply air removes moisture, and the cooled, drier air feels significantly more comfortable during summer heat.
