The unit features highly-efficient 2-stage heat recovery system and uses outside air for dehumidification mode. The series can be supplied with air volume capacity between 750 up to 36,000 m³/h. The unit operates to dehumidify and heat air in swimming pools in a mixed air mode. This unit type is additionally equipped with an highly efficient heat recovery system. The unit is delivered with a DDC controls which automatically and efficiently regulates all functions. When in stand-by mode without dehumidification the air is recirculated in the swimming pool. When the humidity setpoint has been exceeded the unit switches into dehumidification mode. For this purpose outside air is supplied continuously. The dehumidification stage continues until the actual humidity value lies below that of the humidity setpoint. Subsequently, continuously operating outside air/extract air dampers assume the position to provide a minimum rate of outside air. In the pool mode outside air and extract air dampers are opened to ensure a pre-set minimum rate of outside air for hygienic reasons, the opening of the mixing-air damper is reduced accordingly. Depending on the swimming pool humidity the outside air rate is regulated automatically. In case of overheating of the swimming pool the refrigeration unit is deactivated and the bypass dampers are permanently open in order to avoid heat recovery system. Sample selection of operating modes: Idle mode without dehumidification demand Idle/active mode with low dehumidification demand Active hours operating mode with dehumidification demand at high ambient temperatures Bypass damper mode, fans recirculate hall air through recirculating-air dampers. At the same time the temperature and humidity in the swimming hall is continuously measured. Operation with air-mixing damper, return and supply air fans operating at nominal speed. Possibly remaining heat demand is covered by a reheater. Outside air rate is regulated depending on the swimming pool humidity. In pool mode the minimum fresh air rate is regulated in accordance with the VDI specification. Operation with air-mixing damper, return and supply air fans are operating at high speed.

50 Dehumidification Unit with Air ixing Function Type CAT Functional description of the unit The DencoHappel icro CAT is designed for private and small public swimming pools in hotels, therapy and teaching pools with large surfaces and stable air conditions. Sample selection of operating modes: This unit series is available in 5 unit sizes and can deliver air flow rate from 800 up to 6,500 m³/h. The unit's function is to dehumidify and heat air in swimming pools in mixed air mode. The unit is delivered with a DDC controls which regulates all functions of the system on a fully automated basis. This unit type is fitted with EC fans, a highly-efficient heat recovery facility and a heat-pump cycle. The heat-pump cycle automatically dehumidifies in recirculating air mode during idle period and provides hygienic minimum fresh air rate in active pool mode. When the humidity setpoint is exceeded in the idle mode the unit is activated to enable dehumidification. For this purpose the refrigeration unit is activated. The dehumidification stage continues until the actual humidity value lies below that of the humidity setpoint. When in active hours pool mode the fresh and extract air dampers are opened, the bypass damper is closed. The refrigeration unit is activated in order to start dehumidification. Depending on the humidity, fresh air dampers are actuated to reach a 100% fresh air rate. In both modes, idle and active pool modes, the excess thermal energy is supplied to the pool air. Thus a significant load is taken off the the stationary heating plant. Using an optional pool water condenser a certain amount of recovered excess energy can be fed back into pool water or buffer tank. The integrated control facility uses continuous monitoring technique to maintain air conditions at an optimal operating point. Sample selection of operating modes: Idle mode without dehumidification demand Idle mode with dehumidification demand Active hours swimming pool mode with humidification demand and pool water condenser Bypass damper mode recirculating air, fans recirculate hall air through recirculating air dampers. At the same time the temperature and humidity in the swimming hall is continuously measured. Bypass damper operation recirculating air, fan are operating at nominal capacity. The compressor is activated to enable dehumidification in recirculating air mode. The reheater covers the missing residual heat demand. ixed air operation according to VDI, return fan and supply fan are operating at nominal capacity. The compressor is activated.

Sample selection of operating modes: This unit series is available in 5 unit sizes and can deliver air flow rate from 800 up to 6,500 m³/h. The unit's function is to dehumidify and heat air in swimming pools in mixed air mode. The unit is delivered with a DDC controls which regulates all functions of the system on a fully automated basis. This unit type is additionally equipped with EC fans an highly efficient heat recovery system. When in stand-by mode without dehumidification the air is recirculated in the swimming pool. When the humidity setpoint has been exceeded the unit switches into dehumidification mode. For this purpose supply and return air fans are operated at nominal capacity with continuous mixing of outdoor air until the humidity setpoint is reached. Depending on the humidity, fresh air dampers are actuated in a modulating way to reach a 100% fresh air rate. The integrated control facility uses continuous monitoring technique to maintain air conditions at an optimal operating point. Idle mode without dehumidification demand Idle mode with dehumidification demand Active hours operating mode with dehumidification demand Bypass damper mode, Dehumidification demand is not active. Hall air is continuously recirculated and air parameters are recorded by the controller. ixed air operation, Dehumidification demand is low. The unit dehumidifies with a minimum outside air rate. The reheater covers the possibly missing residual heat demand. ixed air operation according to VDI with a minimum outside air rate, return fan and supply are operating at nominal capacity.
