Being a thin tube it will not hold a lot of liquid and so will also not hold a lot of lubricant. I’ve only used electronic valves with my own controllers so I don’t know how to adjust the type you have (assuming it is adjustable?).Ī guess as to what the downward loop in the suction line before the accumulator is for: if it is not just to isolate vibration then it might be the first line of defense against flooding. It is also possible I think that your tx valve may not be adjusted properly. I have found with some component arrangements it can be better if the fan blows air on the coil and other arrangements it was better to suck the air over the coil. What you need is an air flow that is more effective at getting warmer air into good thermal contact with the evap fins and then move the air on asap to get fresh warmer air over the fins, not just a stronger fan. It is not enough to just put a stronger fan. If your evap is freezing up that suggests to my mind that you definitely do not want more refrigerant, you are shifting more heat than your existing fan and evap coil combination can handle and, I think, you need to try much harder to get better airflow over the evap coil. The expansion valve is supposed to regulate the superheat of the gas leaving the evaporator. Posted in home hacks, Misc Hacks Tagged air conditioning, collant, compressor Post navigation If you just need to cool your desk, you might just get some ice in a metal can. We’ve seen other homemade coolers, but they are more like swamp coolers. As much as we like a good hack, our advice is to move to a different apartment building. He’s looking for suggestions on how to make it work better. The more successful one works better but still has a problem with the evaporator freezing that he’s trying to solve. The flow control through the heat exchanger turns out to be very tricky, so claims he mostly got ice right at the inlet and minimal cooling through the evaporator. The very first attempt didn’t quite work as well, using a refrigerator compressor and an evaporator from a baseboard heater. The successful one started out as a hot water heater. The two attempts he made at building his AC came from donor parts. He’s not starting completely from scratch. It does, though, have a water circuit for air conditioning, so he decided to hack a few experimental air conditioners. apartment doesn’t have central air conditioning - the kind that connects to a forced-air heating/cooling system. But in more moderate climates, it isn’t all that unusual. There are some parts of the world where living without air conditioning borders on unthinkable.
