A method for determining antifreeze content in a fluid of a heating, ventilation, and air conditioning (HVAC) system includes receiving, in a processor, measurement data of the fluid, the measurement data comprising a measured temperature of the fluid and a measured speed of sound in the fluid, calculating, in the processor, for each of a plurality of antifreeze concentration values a fitting parameter, using the measurement data and one or more of previous measurement data or previous antifreeze concentration data, and determining, in the processor, an antifreeze concentration in the fluid by selecting the antifreeze concentration value with an optimal fitting parameter.
A method for determining antifreeze content in a fluid of a heating, ventilation, and air conditioning (HVAC) system, the method comprising:
A device for determining antifreeze content in a fluid of a heating, ventilation, and air conditioning (HVAC) system, the device comprising a processor configured to:
A computer readable storage medium having stored thereon computer program code which, when executed by configured to control a processor (21) of a device (2), causes the device to at least:
