The Engineering Mindset for a 15KW (with PHE) Capacity System , We used TE12 - Orifice 6 ( We didn't consider the Sub-Cooling caused by PHE + we weren't using PHE initially) Effectively System was delivering 10kw ODU with 15KW idu with TE 12 Orifice 6. @ 8psi Suction & 275psig Discharge. 1 system later failed as 2 cyclinders of compressor discharge reed went off, as soon as we enabled PHE,( may be or bcoz of TXV) Question is was the failure because of TE12 during normal Operation or the mismatch of PHE & TXV. Accurate Txv is TE5 Orifice 3. for the system (later as we considered additional Sub-Cooling)?

Change of state begins the moment the refrigerant passes through the tx, not just at the end of the evaporator. There is one constant temperature for as long as the refrigerant is changing from liquid to gas.

@teravolt61135 жыл бұрын
It's the external equalizer line. Big evaporators need externally equalized TXVs because pressure drops considerably inside them, so the equalizing pressure is sourced from the evaporator's outlet rather than from the TXV's outlet.

Had a crummy professor for Thermodynamics. They didn’t think it was important to explain how a TXV valve works. After watching this, I have no idea how they could be so obtuse. Understanding how this valve operates is absolutely critical to be able to think about what’s happening with these systems. Screw you professor Patel.

Not sure if you care to know, but around the 2:10 mark, you show a recording of a sensing bulb strapped to the suction line and it’s strapped with two zip ties Obviously it’s still going to sense the temperature off the suction line, but you should use a metal clamp instead because that metal clamp helps distribute the “coldness”-for lack of a better term-evenly around the sensing bulb and not just on the mating surfaces. Not trying to be a know it all. I just assume you like to constantly get new relevant info. Thanks Paul! I’ve almost watched all of your videos

@1965ace4 жыл бұрын
So basically a higher temperature at the other side of the evaporative coil opens the valve and a cooler temperature closes it. The goal is to keep the refrigerant a gas for the compressor to compress (liquids don't compress) and to keep the system from freezing in an ac unit. So in adjusting tightening the spring lets less refrigerant in thus increasing exit temperature and loosening decreases exit temperature.

Working principle of TXV: TXV controls the volume of refrigerant flow. Volume of refrigerant passing affects pressure. Narrower means lower volume and less pressure and cooler. This will decrease strength of bonds (ectothermic) and give away heat, resulting in cooler and gaseous state

@saluteyanomaly76283 жыл бұрын
Quick question: when you say the expansion valve will open more, you mean there will be more vapor in the flow (higher x value) or less ? If you cooling load is high (low x value), then the temperature after expansion, as well as after evaporation are high. In order to decrease the temperature after evaporator, you should decrease the temperature after expansion, this means you need have flow with high vapor fraction after expansion. Combining this logic and your description, the more expansion valve open indicates more vapor fraction in the flow. Am I right?

@consaka13 жыл бұрын
Ok, correct me if I'm wrong but in order to get a liquid to the compressor you would have to overfill the system to begin with. A system with the proper amount of refrigerant has to compress it to get it into liquid form to begin with. Once you let the pressure of from say the TXV being wide open, the liquid would simply turn back into a gas and because of no pressure it would just stay in a gas form.

The freon doesn’t carry heat to the compressor. The compressor compresses freon which cause it to get hot.
