IS 16368 : 2015 : Test Procedure for Thermosyphon Type Domestic Solar Hot Water Heating Systems

Reaffirmed 2020

1 SCOPE

This standard covers test procedure to evaluate thermal performance of domestic solar hot water systems, using flat plate collector (FPC) or evacuated tubular collector (ETC), working on thermo-syphonic flow of water under natural outdoor conditions.

The solar water heating system may employ electric heater in the storage tank as an auxiliary source of heating, however performance of the system is evaluated under solar operation mode only.

This standard may also be applied to solar water heating systems employing unglazed/glazed solar flat plate collector, or any other non-concentrating design of solar collectors with appropriate benchmarking of performance parameters.

This standard does not apply to solar hot water systems employing concentrating solar collectors.
