[Ralph Doncaster] has a geothermal warm pump which is accountable for supplying warm for his home. He’s been looking into some hacks that would make it a lot more effective as well as made a decision that the freon (R-22) needed to be tweaked. Some would state the stuff is poor for the environment, so he made a decision to go a different route. He replaced the Freon with propane, utilizing this rig to make the fuel-grade propane a lot more like cooling-grade propane called r-290.
He bought the gauge set which is utilized whenever a technician services an A/C system (but you can likewise see it in this other A/C propane hack). That’s crucial since it’s accountable for making sure the old coolant is recaptured (his hose failure nixed this part of the plan) as well as the new coolant goes where it must at the right pressure. however before discarding in propane from the regional hardware store he needs to dry it out. Fuel-grade propane can have wetness in it, which can be poor for the cooling system. He gotten a drier device, the grey bulb seen above, as well as soldered it on one end to a propane torch fitting as well as to a valve connection on the other. now he might eliminate wetness as he pressurized the system.
Everything is working again, as well as the cooling side of the system gets much colder. He plans to do a lot more testing as time goes by.
