BDP SERIES
In our standard models the heating fluids is water, reheat coils use copper pipes and coated
aluminium fins in order to resist in corrosive environments.
- Condenser coil is used for drying and warming the air due to R-407C refrigerator
Condenser coil are made of copper pipes and coated aluminium fins in order to resist in
corrosive environments.
- Evaporator coil have a stainless steel condensation tray on the bottom, including a drain
pipe to outside.
Usually designed for low air speeds with a limit around 2.7 m/s maximum speed
recommended to avoid droplet condensation.
1.2.4 – VENTILATION SECTION.
BDP Heat pumps assemble one or more radial centrifugal fans. The fans layout can push air
upwards, in front or behind, and optionally to false ceiling. They can change available standard
pressure and flow.
Fans are the elements to produce air flow. By definition, are devices that produce lower differential
pressures under 0.25 Kg/cm2, at sea level.
1.2.5 – COOLING CIRCUIT.
Depending on the model can have one or two circuits; optionally you can include more
circuits. Each consists:
* SCROLL compressors, hermetic or semi-hermetic with internal protection.
* Evaporator coil made of copper tube and aluminium fins for chlorinated air.
* Battery condenser copper tube and aluminium fins for chlorinated air.
* Titanium condenser pool water.
* High Pressure and Low Pressure (LP / HP) switches with manual reset.
* Expansion valve.
* Drier filter.
* Liquid Viewer.
* Liquid Deposit/s.
In some models whose compressors have a power higher than 7.5 hp per circuit are installed the
following:
* Shut-off valves to prevent excessive migration of oil to the compressor.
* Replaceable drier filter.
* High and low pressure gauges.
Standard models condense in water and air (40% water and 60% on air), after reaching the air
set point.
1.2.6 – HYDRAULIC CIRCUIT
BDP heat pump models have a titanium condenser for heating water pool and have a flow
switch in the condenser inlet. In case of having no water flow, machine would pass to condense 100%
air.
