Reply to comment by AcademicGravy in Heat Pumps could supply 20% of building heating by 2030. Supercritical CO2 heat pump sales in Japan have now reached a total of 8.5 million units. by DisasterousGiraffe

It would be a practical physical condition of operation, not jargon. What is the low side pressure of these systems when running?

I guess I'm just trying to say if you are referring to the pressure on the high side of a refrigeration system using the term static pressure is very confusing. The low side pressure of these systems would differ depending on the conditions the system are in. The temperature of the air going over the coil for instance would change the pressure. The static pressure in the ductwork would also be a factor on the operating pressures of the low side.
