Hello guys
Having a bit of trouble with R22 Refrigeration system, including 3 bottle coolers and 3 flooded draught beer temprite coolers. One of the bottle coolers continues to leak from the same location on the evaporator coil inlet end plate. The leak is caused by excessive frosting from the TXV that suggests a blockage or shortage of gas in the system. I have replaced the TXV and orifice and checked the liquid line sight glass is full. I am still getting the same problem with the TXV not feeding the coil correctly causing frost up to create leaks on the coil end plate. The other two bottle coolers TXV seem to control correctly feeding the evaporator coils.
The T\stat is a danfoss mechanical type recommended for a bottle cooler. The sensor capillary is mounted through the coil fins sensing coil temp. This t/stat controls a liquid line solenoid.
