- Digit 23=T
Full equipment (BPHE + Water lines + 3-ways water valve + heaters + flow-switch + insulation)
(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
- Digit 23=V
Naked (BPHE + insulation)
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
(3) At high speed with nominal air flow.
- This type of unit remains an air-cooled chiller before modification into a Total Heat Recovery unit. Start up and Shut
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
down are always carried out in chiller mode. (freeze protection by standard tank)
- All Free cooling options exclude Total Heat Recovery and not developed for high ambient.
Heat exchanger operating limits:
FWD:
- Operating map : Maximum water temperature depends on compressor load and operating conditions. It may vary
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
from 30°C to 61°C. For details performance consult Order Write Up.
Accessories - Hot water coil:
- Flow-switch : The flow-switch is fitted on water line to monitor a to low water flow through the Total Heat Recovery
*water temperature: min. +2° C/max. 100° C
heat Exchanger.
*absolute service pressure: min 1 bar/max 11 bars
- Heaters are placed on water piping to heat the whole Total Heat Recovery system (water piping, water 3-ways valve,
BPHE).
- To protect the Total Heat Recovery circuit during winter or off mode, circuit must be filled by by glycol with at least a
concentration of 35%.
- Introduction of an expansion tank and safety valve is recommended on the water circuit.
- The water valve is a safety device to allow a limited water flow below 25°C of THR entering water. Above 25°C,
the 3-ways water valve is full open.
