2.4 Functional principle of the F800
The figure shows the refrigeration circuit with pool water condenser essentially consist-
ing of: scroll compressor (1), air-cooled condenser (4) and pool water condenser
(Option)(3), expansion valve (8) and evaporator or air- cooler (9). Refrigeration circuit
filled with refrigerant.
1: compressor
3: pool water
condenser (accessory)
4: air-cooled condenser
5: high-pressure monitor
6: schrader valve
7: dryer/collector
8: expansion valve
9: evaporator (air cooler)
10: anti-icing
protection
thermostat
11: low-pressure limiter
12: venting valve
13 pool water
connection R 1/2"
Fig. 2-2: Refrigeration circuit
The hall air is evacuated by the centrifugal fan and cooled over the air cooler.
Depending on the humidity, the temperature can drop below the dew point; the water
steam in the hall air condenses on the fins of the air cooler and collects in the conden-
sate tray. The water condensate drained off through a pipe.
The dehumidified and cooled air is then re-warmed and supplied to the indoor swim-
ming pool hall.
