Is the open loop well water cooled system convertible into the closed horizontal loop? What if the well runs dry after some time as is common to many regions here?
Yes it is easily convertible. However, in order to change a system from open to closed loop, one pressure switch must be changed but two should be, the low pressure switch must be and the A/C defrost switch should be. You can change these pressure switches without affecting the freon because we use shrader valves and the switches are electronic. They simply screw off and on. As you screw one off a depressor allows the freon to shut-off thereby not allowing any freon to escape while changing switches. This is a major benefit to our equipment. It is not so uncommon to switch from an open well to a closed loop when a well starts to run low. It is also important when considering inventory.
