It is in our power to create comfortable conditions so that the old age of people who did not manage to live in a family circle, passed with dignity. Ventilation of homes for the elderly is an important component of the right microclimate, therefore preserving health and, as a consequence, prolonging life. Elderly homes are a special type of premises. The natural ventilation and the ventilation devices provided by the construction of the building can not always provide sufficient air exchange rate. It should be taken into account that elderly people are a risk group: a weakened immune system is extremely vulnerable to the effects of allergens, dust, and chemicals that enter the room through open windows. Consequently, there is a need for additional ventilation.

Ventilation with heat preservation

Elderly people need higher room temperatures. You have probably noticed that the elderly wear warm clothes, even in the summertime. Slowing down the body’s metabolic activities creates barriers to keeping the body’s heat exchange at an adequate level. If the standard (DBN B.2.2-15-2005) temperature of living rooms in winter is 20 ° C, for homes with elderly and disabled people this figure reaches 22 ° C. At the same time, elderly people also need more oxygen in the air. After 50 years of age, a person’s respiratory organs become significantly weaker, and blood vessels deliver only 20-30% of the oxygen received by the lungs to the tissues. The question is – how to keep the warmth necessary for elderly people and at the same time provide high air quality?

The principle of operation of PRANA supply and exhaust ventilation systems is based on recuperation. Inside the air handling unit two oppositely directed air flows are formed: one carries fresh air from the street and the other takes out the exhaust air from the premise. The streams pass through a copper heat exchanger without mixing, but the thin plates of the heat exchanger allow the exhaust air to transfer heat (in winter)/cold (in summer) to the fresh tidal air. Unlike opening windows, which is often practiced in nursing homes, this method of ventilation retains valuable heat in the room. And thus creates significant savings on heating (in winter) and air conditioning (in summer). PRANA recuperator creates a healthy microclimate of the room, balancing a comfortable level of humidity for people and the inflow of fresh air. It is the optimal ventilation solution for people with weakened immunity and chronic diseases.
