Functions
Solar Thermal Application:
- daily and accumulative system heat gain for solar hot water system, solar heating and cooling system;
- system efficiency and heat loss coefficient;
- collector efficiency and heat loss; generate solar collector efficiency curve according to China or Europe or Australia standard;
- comparative testing for two collectors or systems;
- auto acquisition of solar irradiance, flow rate, temperature and wind speed, which can be displayed in table or graph, it can also collect other inputs as customer request.
Auto-calibration of temperature sensor: enable the accuracy;
Calculation: daily and/or accumulative heat gain, efficiency
Features
