Indoor VRV Units (Nominal Capacity) - Ceiling Mounted Round/4way flow cassette type Unit with inbuilt occupancy sensor & floor temperature sensor Supply, Installation, testing & commissioning of Ceiling Mounted Round/4way flow cassette type Unit with inbuilt occupancy sensor & floor temperature sensor. The unit shall include pre-filters, fan section and DX coil section. The plastic body shall be light in weight and shall be able to suspend. The fan shall be aerodynamically designed diffuser turbo fan type. Unit shall have an external attractive panel for supply and return air 2 .The cassettes units shall have dual sensor which detect the presence of people and floor temperature to provide comfortable air-conditioning and energy saving. The sensor should detect human presence and adjust the airflow direction automatically to prevent drafts. Room temperature should increase upto 4 deg C or the indoor to be switched off when no people are detected or as per user preference. The sensor should detect the floor temperature and automatically adjusts the operation of the indoor unit to reduce the temperature difference between the ceiling and the floor. All 4 louvers of the unit shall be independently adjustable for position as per user preference. (Minimum Cfm & capacity as per below) a) 2.01TR/ 671 CFM.
