Variable Refrigerant Flow (VRF)/Variable Refrigerent Volume (VRV)

SITC of Variable Refrigerant Flow (VRF)/Variable Refrigerent Volume (VRV) modular type air-conditioning Equipment complete with indoor and out door units Individual controllers also provide for each indoor units and should be capable of integration with the Computer System based Building Management System of HVAC.

Outdoor Unit (cooling Only)

Supply of Modular type Variable Refrigerant Flow/Variable Refrigerant Volume air cooled Outdoor units suitable for cooling having 100% hermetically sealed inverter type twin Rotary/Scroll Compressor(s), minimum two compressors (with individual seperate PCB) for above 14HP modules, microprocessor based Controller, top discharge type condensing unit(s), with R-410-A Refrigerant or any eco friendly gas, vibration Isolators with suitable foundation etc. complete as required. To have better efficiency condensor fan shall be capable to operate at different speed with respect to load.The unit shall deliver the rated capacity and in confirmation as per IS 18728:2024 and CPWD Specifications and work even at 50°C ambient temperature without tripping. The system shall be able to deliver 100% of the rated capacity upto 39 Degree Celcius.The unit shall be suitable to work on 400V +/- 10%, 3 Phase, 50Hz AC power supply and BMS compatible. The unit shall be filled with first charge of the refrigerant and ready for use as required. The condenser should be coated with a hydrophilic film to prevent water accumulation on the surface of the heat exchanger, enhance water dispersion, and reduce the risk of degradation, thereby improving overall performance and durability. The Indian Seasonal Energy Efficiency Ratio (ISEER) of the unit shall be as per Energy Conservation and Sustainable Building Code (ECSBC) 2024 as below and complete as per specification, connections, inter connections etc. as required. (For capacity<40 kWr ISEER 7.4, Capacity > 40 and <70 ISEER 7.5, Capacity > 70 ISEER 7.6 for Super ECSBC Building)Note:- Out door unit stand also included in the price.
