Carrier 30RB-210R - 12.2.4 TOTAL;PARTIAL FREE COOLING (Option 305 A; 305 B); 12.2.4.1 Physical characteristics of units with total and partial free cooling

12.2.4 - TOTAL HEAT RECOVERY (option 50)
Suitable for heating, domestic hot water production, agriculture and food industry, industrial processes and other hot-water requirements.
With the total heat recovery option it is possible to reduce the energy consumption bill considerably, when compared to conventional
heating equipment such as fossil fuel boilers or electric water tanks.
Operating principle
If hot water production is required, the compressor discharge gases are directed towards the heat recovery condenser. The refrigerant
releases its heat to the hot water that leaves the condenser at a temperature of up to 60 °C. In this way, 100% of the heat rejected by
the liquid chiller can be used to produce hot water. The hot water temperature is controlled by the chiller's SmartVu
TM
control unit
NOTE: Heat recovery is only possible if the unit is producing cooling at the same time.
