Thermophysical Property Data and Model Evaluation for Ammonia-Water Mixtures

In this report, we explore the thermophysical properties of ammonia-water mixtures, in particular their specific heat capacity variations under different temperature, pressure and density conditions. Ammonia-water mixture, as an environmentally friendly refrigerant, has a wide application prospect in absorption refrigeration systems, especially in reducing environmental pollution and improving energy efficiency. However, the lack of accurate thermophysical data under extreme conditions makes model prediction and system design difficult.
