Central air pool heater - House cool mode

This example was drawn on the base of HVAC schematics in the post "Central Air Pool Heater" from the blog of Nathan Stratton.
"With House Cool Mode, hot gas leaves the compressor runs through the reversing value into the condenser where it condenses into a liquid. Valve #1 is ON so liquid is able to leave the outside unit and run through the filter dryer and site glass into the evaporator upstairs in the house where the liquid flashes into a gas as it passes through the expansion valve and absorbs heat from the air passing through the evaporator. The cold gas travels downstairs and outside to the compressor and the cycle starts all over again." [robotics.net/ projects/ central-air-pool-heater/ ]
