Heat Exchanger.
Good ventilation is very important, but when the outside air temperature differs considerably from the indoor air temperature, ventilation results in a great deal of energy loss.
The key to heat recovery ventilation and the heat exchanger is that it enables and maximises the exchange of energy between the incoming and outgoing airflows before the energy dissipates in the atmosphere.
The heat exchanger in our HRV units can be used for air temperatures between -30 and +50 șC. The heat exchanger is constructed completely from polystyrene - from the foils to the casing. Only solvent-free elastic adhesives are used.
The heat exchanger is made up of hundreds of these hot and cold triangular ducts, resulting in a large surface heat exchange area and extremely high efficiency of 90%
The triangular ducts in the heat exchanger are arranged so that each one is surrounded by parallel ducts in which the air is in counterflow (see Fig. 1). Each fresh-air duct is surrounded by three ducts filled with warmer exhaust air. Likewise, each duct with exhaust air is surrounded by three fresh-air ducts.
