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 dehumidi-
fication mode. For this purpose outside air is supplied continuously. The dehumidifica-
tion 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 mixed-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.
3.3 Unit configuration and operation of CAIR fricostar Micro compact units
Thanks to the modular design of the units and various applications for each case, a
