Worked today on my central air pool heat/cool system. The goal for the new system is to be able to operate in normal house cool mode, pool heat mode, and pool cool mode all in one HVAC system. The new system uses a reversing valve to pump down unused portions dramatically cutting down on the amount of refrigerant needed.
