Originally designed using VRF and package units to handle the fresh air in the hotel. Upon studying the case, it was decided that a redesign was needed, we teamed up with our business partner who recalculated the heat load and offered to change the 100% fresh air package units to air handling units with VRV kit and HSHP for humidity control. The use of HSHP offers a more efficient solution with lower operating cost since the HSHP does not use an electric heater. Additionally, the new design contemplated changing the splits located in the lobby to VRV units to maintain the same technology throughout the project and to be able to control all units with i-Touch Manager (iTM).
NOTE: The owner was asked to validate the new design with an external consultant of his choice. This was located in Chile, due to the COVID-19 pandemic situation in 2020 we relied on the use of webinars and video conferences, we trained the Chile consultant on the Daikin product portfolio and with the support of our Chile office, he was invited to visit the VRV facilities at the Costanera Center in the city of Santiago.
