Latent cooling load
Latent cooling load is a measure of the amount of energy that is necessary to dehumidify the air in a building, for example, regardless of the outdoor humidity. Cooling load needs to be considered when a cooling system is being dimensioned.
Legionella in cold water systems
When designing cold water systems water temperature, retention time, pipe material and regular system maintenance is of great importance in order to prevent micro bacterial growth.
Air conditioning and heating systems in buildings that have special inventories or which are especially vulnerable to the effects of water damage can have leakage-protection installed. The system automatically monitors flow in supply and return pipes. In case of divergences, it shuts off both supply and return.
Legionella in hot water systems
When designing hot water systems the water temperature, water retention time, pipe material and making way for regular system maintenance is of great importance in order to prevent microbacterial growth.
Legionnaires' disease is a serious lung disease which is caused by breathing in aerosols infected with the bacteria Legionella Pneumophila. Of those who are infected up to 30% will die.
Legionella bacteria can be the cause of two illnesses in humans: Legionnaires’ disease, an infection that produces pneumonia and Pontiac fever, which resembles acute influenza. When designing air conditioning systems, how to reduce the risk of bacteria growth must be considered.
