To optimize energy savings on VRV/VRF/Chiller air conditioning systems in the client’s premises and provide alerts and analysis of VRV/VRF/Chiller condition for preventive maintenance planning.
It is an autonomous artificial intelligence system that continuously tracks and senses, in real time external and internal weather conditions (dry bulb temperature and relative humidity) to optimize the VRV/VRF/Chiller operations. The OPTICOOL proprietary Algorithm computes the optimal operations of the VRV/VRF/Chillers taking Enthalpy (relative humidity, dry bulb temperature and heat load) into consideration. This info is then communicated to the VRV/VRF/Chiller system via our Proprietary Integration Protocol Algorithm and varies the VRV/VRF/Chiller operations to create optimal operation for energy saving. Thus, creating the most optimal and efficient air conditioning operations.
It does, however the VRV/VRF/Chiller does not do this efficiently, as only one indoor temperature sensor unit is used (dry bulb temperature only). This methodology is convenient for standard VRV/VRF/Chiller, that does not take into considerations of the Enthalpy conditions. With Enthalpy latent heat is taken into consideration where 20-30% savings can be achieved on energy usage.
1. Wireless Sensors (internal and external), power meter, wireless setup – not necessary when BACnet is available in the VRV/VRF and Interface Cards supplied by the Manufacturer of the Chillers
2. Intelligent Controller.
3. Proprietary OPTOCOOL Algorithm.
4. Cloud Control Center Software and User Interface.
Partially by client at sensitive areas like hotel rooms as an example with the assistance of OPTICOOL technicians and engineers. Installation time may vary according to the size of the facilities and the availability of access. Generally, could vary from 1 to 3 months.
Minimum maintenance is required, all components are allocated as back up stock for the client during the EPC/Warranty/Service Level Agreement period. All components are developed as a plug and play device. Replacement can be available within 48hrs or soon as requested. (Depending on circumstances).
All data is real time, so savings is measured by real time via the Thermal Power (TP) method and the savings tabulated and consolidated monthly with a report issued along with the invoice on prior agreed savings share (EPC Contract) for the month.
In summary, the TP method (where the indoor unit operations are influenced by parameters i.e., external and internal dry bulb temperatures, relative humidity and occupancy) derives a real time baseline for comparisons of the data when the system is turned on to an interpolation via regression analysis linear model (KWh vs BTU). This becomes the baseline in real-time for savings. (The details of the Measurement & Verification procedure is available on request).
The system has real-time tracking that is accessible to the client for viewing and downloading as necessary for own verification. Additionally, client will also have the option to turn the system off and observe the change in electrical energy usage by the VRV/VRF/Chiller at any time desired by the client.
For professional verification, every half yearly as agreed with client, we will do a Measurement & Validation assessment report by a certified M&V professional engineer and endorsed accordingly to ensure credibility of the savings reported
