Question:
What are Pd_t and Ps_t? Are they pressure or temperature values?
Answer:
Both Pd_t and Ps_t are temperature values:
Pd_t is the saturation temperature corresponding to the high-side pressure (Pd)
Ps_t is the saturation temperature corresponding to the low-side pressure (Ps)
These values are obtained by referencing the measured pressures (Pd and Ps) against refrigerant-specific pressure-temperature charts or software tools in refrigeration systems.
