Several dynamic models of heat pumping systems, using R410A and R744 as refrigerant, have been developed. They all use similar components with similar capacities and the same boundary conditions for a fair energy efficiency comparison. Simulation results show that the seasonal COP_c of an R744 ...

it's just been filter changes. I have a coil service due this year for the AC "heat exchanger" in the forced air system. Installed, this was rated above 95% efficient for however forced air efficiency is measured. I suspect it's about 1/3 of the way through its expected service life...

The dehumidification efficiency and enthalpy efficiency were significantly increased in comparison to those of one-stage systems. Martinez et al. (Martinez et al., 2018) used TRNSYS to simulate and compare a desiccant wheel air conditioning system using a heat pump and an indirect evaporative cooler...
