PDP type package units are special air handling units designed to remove excess moisture from surface evaporation in indoor swimming pools and to provide optimum comfort throughout the year in the pool area.

If the relative humidity rises above 60%, it not only disrupts the comfort conditions, but also causes condensation on the walls and windows, and damages all the installation elements in the space.

PDP series air handling units are package type air conditioning units designed to provide the highest comfort conditions within the pool and to eliminate high absolute humidity when necessary.

NIGHT OPERATION WITH NO DRY PROCESS

The return air fan is turned off and the supply air is operated. The cooling circuit is closed. The return air is passed through the mixing damper and the after heater to heat the pool area with sufficient air.

NIGHT OPERATION WITH DRY PROCESS APPLIED

In night operations where usage is not intense, dehumidification is performed by passing the return air through the Heat-Pipe heat recovery battery and then through the evaporator. The dehumidified air is sent to the room in a heated state. (It is heated up to the desired values when necessary.)

DAY OPERATION WITH DRY PROCESS

The required amount of fresh air is mixed with the return air. The return air is passed through the Het-Pipe heat recovery botriosin and then through the evaporator, and the nebulisation process is carried out. After the mixture is kneaded, the dehumidified air is passed through the Heot-Pipe upper part, frost and condenser, and sent to the mohole in a heated state. Return air is exhausted as well as fresh air.

DAY OPERATION WITH NO DRY PROCESS

Low level of fresh air is used.
When necessary, only heating is done.
Compressor is off.

OPERATION IN SEASONAL TRANSITIONS (YES/NO DRY)

Dehumidification and ventilation processes are carried out with maximum outside air.
