1. The refrigerant absorbes the calories from the cold room through the evaporator
2. The refrigerant is compressed and then discharged as a gas at a high temperature.
3. The refrigerant goes through our subermerged primary exchanger to gives its calories to the storage water. It then goes back to the condenser to finish its cooling cycle.
4. When you need it, the equipement will heat your water using the calories of the storage tank.
