Dehumidification unit with air recirculating and heat pump function
Type CAU
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CAU is mainly designed for private swimming pools
and can be delivered in 4 sizes. The unit operates to dehumidify and heat air in swimming pools in a recirculating-air mode. The unit is fitted with a full electronic control
system that automatically regulates system functions.
In recirculating-air mode without dehumidification the air is recirculated in the swimming pool.
The multifunction humidity switch is installed in the swimming pool and activates the
unit in dehumidification mode as soon as the humidity setpoint has been exceeded. At
this point the fan is switched into speed 2 and the refrigeration circuit is activated. The
dehumidification process continues until the humidity setpoint is reached.
Subsequently the fan is switched into speed 1 and the circuit compressor is stopped.
Using an optional pool water condenser a certain amount of excess energy produced
by the heat pump cycle can be fed back into swimming pool water or similar circuit
system.
Operation mode with dehumidification demand
Supply air fan runs at high speed. The necessary transmission heat is supplied by the reheater coil.
Using an optional pool water condenser a certain amount of excess energy can be fed back into swimming pool water.

Dehumidification Unit with Air Mixing and Heat Pump Function
Type CMU
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CMU is designed for private and small public swimming pools with short-term utilization time. The unit features short overall length and a
highly-efficient heat pump.
The series is available in 6 sizes. The unit operates to dehumidify and heat air in swimming pools in a mixed air mode. The unit is delivered with a DDC controls which regulates all functions of the system on a fully automated basis.
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. At this point the supply-air fan is operated at nominal air flow and the
extract-air fan maintains the proper air movement. The refrigeration unit is activated in
order to start dehumidification. Using the bypass damper a certain part of return air is
mixed without further treatment with dehumidified air that has passed through the refrigeration cycle. The dehumidification stage continues until the actual humidity value lies
below that of the humidity setpoint. Then the refrigeration unit is deactivated.
When in active hours swimming pool mode the fresh and exhaust air dampers are opened, the bypass damper is closed. Then the refrigeration unit is activated. In the event
of overheated swimming pool the refrigeration system is deactivated.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.

Dehumidification Unit with Air Mixing and Heat Pump Function
Type CAM
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CAM is designed for private and large public swimming pools. The dehumidifier operates using outside air and a heat pump. At the same
the unit is performed in a compact and variable configuration.
The series can be supplied with air volume capacity between 750 up to 45,000 m³/h.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
Besides a refrigeration unit (heat pump) this unit type is additionally equipped with an
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. At this point the supply-air fan is operated at nominal air flow and the
extract-air fan maintains the proper air movement. The refrigeration unit is activated in
order to start dehumidification. Using the bypass damper a part of return air is mixed
with air dehumidified through the refrigeration unit. The dehumidification stage continues until the actual humidity value lies below that of the humidity setpoint. Then the
refrigeration unit is deactivated.
In the pool mode outside air and extract air dampers are opened to ensure a pre-set
minimum rate for 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 the event of overheated swimming pool the refrigeration unit is deactivated and the
bypass dampers are opened to divert the heat recovery system.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.

In case of overheating of the swimming pool and high outdoor temperatures the heat pump is blocked. The unit operates for ventilation
and dehumidification in air mixing or only outdoor/exhaust air mode.
The fans are operating at high speed. In case of an optional bypass
of the heat recovery system the heat recovery is not used thanks to
a damper system and at the same time the air flow rate is increased.

If the swimming pool is overheated during the night time or idle period
the unit ventilates only in outdoor/exhaust air mode. The fans are
running at high speed and deliver cooling for the swimming pool to
reach the setpoint temperature. In case an optional bypass is used heat recovery is not employed thanks to a damper system and at the
same time the air flow rate is increased.

Dehumidification Unit with Air Mixing and Heat Pump Function
Type CMP
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CMP is designed for various kinds of High Performance private and large public swimming pools. The unit features highly-efficient 3stage heat recovery system. The dehumidifier operates using outside air, heat
recovery facility and a heat pump.
The series can be supplied with air volume capacity between 750 up to 37,500 m³/h.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
Together with a heat pump, this unit type is additionally equipped with an highly-efficient heat recovery system using a double-plate heat exchanger. 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. At this point the supply air fan is activated and the extract air fan maintains proper air movement. The refrigeration unit is activated in order to start
dehumidification. The dehumidification stage continues until the actual humidity value
falls below that of the humidity setpoint. Then the refrigeration unit is deactivated.
In the pool mode outside air and extract air dampers are open to ensure a pre-set minimum rate of outside air for hygienic reasons. Then the refrigeration unit is activated.
Depending on the swimming pool humidity the outside/extract air rate is regulated
automatically.
Using an optional pool water condenser a certain amount of excess energy produced
by the refrigeration cycle can be fed back into swimming pool water.
In the event of overheated swimming pool the refrigeration unit is deactivated and the
bypass dampers are continuously open to divert the heat recovery system.

Dehumidification Unit with Air Mixing Function
Type CWR
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CWR is designed for private and large public swimming pools. The unit uses outside air to dehumidify and features compact and variable
construction system.
The series can be supplied with air volume capacity between 750 up to 45,000 m³/h.
The unit's function is to dehumidify and heat air in swimming pools in mixed air mode.
This unit type is additionally equipped with an 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. After that continuously operating outside air/extract air dampers are closed.
In the pool mode outside air and extract air dampers are opened to ensure a pre-set
minimum rate for 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 the event of overheated swimming pool the bypass dampers are opened to divert
the heat recovery facility.

Dehumidification Unit with Air Mixing Function
Type CWP
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar CWP is designed for various kinds of High Performance private and public swimming pools. 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.

Dehumidification Unit with Air Mixing Function
Type CAT
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar Micro CAT is designed for private and small public
swimming pools in hotels, therapy and teaching pools with large surfaces and stable
air conditions.
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:
Sample selection of operating modes:

Pool mode over-temperature
Idle mode over-temperature "free night cooling"
If the pool overheats and setpoint temperature is exceeded the heat
pump is blocked. The unit ventilates and dehumidifies in pure outdoor and exhaust air mode. If a heat recovery bypass is used - heat
recovery is not employed and at the same time the air flow rate is increased.
If the swimming pool is overheated during the night time or idle period
the unit ventilates only in outdoor/exhaust air mode. The fans are

Dehumidification Unit with Air Mixing Function and Heat Pump
Type CWT
CAIRfricostar
Functional description of the unit
The DencoHappel CAIRfricostar Micro CWT is designed for private and small public
swimming pools in hotels, therapy and teaching pools with a large hall volume.
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.
Sample selection of operating modes:
Idle mode without dehumidification
demand
Bypass damper mode,
Dehumidification demand is not active. Hall
air is continuously recirculated and air parameters are recorded by the controller.
Idle mode with dehumidification
demand
Active hours operating mode
with dehumidification demand
Mixed air operation,
Dehumidification demand is low. The unit
dehumidifies with a minimum outside air rate.
The reheater covers the possibly missing residual heat demand.
Mixed air operation according to VDI with a
minimum outside air rate, return fan and supply are operating at nominal capacity. The
reheater covers the possibly missing residual
heat demand.
