- Q: OK, so this is a follow up question to my previous one where I said my furnace was blowing out cold air.The repair tech that came out said my heat exchanger is cracked. I told him that I replaced the original heat exchanger 4 years ago and the tech said that since the heat exchanger has a faulty design (which is on the manufacturer) a replaced heat exchanger is only good for about 5 years. He sugguested I get the entire furnace replaced and that putting a 2nd replaced heat exchanger in the furnace will cost you additional labor costs as well as going through the same problem again in a few years.Is this guy telling me something honest? or should I pursue in getting the heat exchanger replaced again?
- You might do well to call the manufacturer and ask if this is a common problem on this model. I've only see a couple of cases of a heat exchanger lasting only a few years, then having the same problem again a few years later. If you contact the mfr and complain about the short exchanger life, and the labor expense to replace it, they may be willing to offer a replacement furnace. Threatening a complaint to the BBB may help also. If that doesn't work, and you're stuck with resolving the problem yourself, I'd consider replacing the entire furnace. Most furnaces today have a minimum 10 year heat exchanger warranty, some of them have lifetime warranties, on the exchanger only. I wouldn't put any more money into that furnace. 20+ yrs HVAC tech.
- Q: or air exchanger alone will solve our problem
- yes you do. more in the winter months check with local home store to find out what your humidity level should be .
- Q: how do i get the most heat from my fireplace ?
- A metal backing (shiny) behind the fire will help project more heat outside the fireplace itself.
- Q: I understand that it is essentially a loop in which a refrigerant travels around through the Earth's interior either cooling or heating and in the end expending that temperature into a home or building..as we know, technology is always progressing and ways of becoming more innovative and efficient are always just around the corner...so my question is...1.) What are some efforts or discoveries that increase the efficiency of the energy conversion in the process of Geothermal heating and cooling? So from what I interpret, are there any new ways to make the refrigerant travel faster...different types of refrigerant that are more efficient...a compressor that is able to get the job done more efficiently...etc...I had an idea though, I heard different types of refrigerants can be used such as air, water...etc???
- I concur with the prior poster that your understanding is not accurate Basically a Geothermal HVAC (or Ground Source Heat Pump) uses water or a water/antifreeze mixture in the heat exchanger. This water is either recirculated in a very long underground pipe system (closed system) or drawn from a well, lake or other water source (open system). In cooling mode (A/C) a geothermal heat pump uses refrigerant to move heat from the building into the water via a heat exchanger. In heating mode, it operates in the reverse and moves heat from the water to the refrigerant and ultimately the building. A standard heat pump operates in the same manner however instead of using ground temperature water, it uses ambient temperature outdoor air. The greatest advantages of geothermal heat pumps in a 4 season climate is that they are much more efficient than the alternative when outdoor temperatures are at their extremes. For example: When it is 25F outside, my geothermal system is pumping heat from 55F groundwater into my 70F house. (Standard system is pumping heat from 25F air into a 70F house) When it is 95F outside, my system pumps heat from my 74F house into 55F water (standard system is pumping heat into 95F air) When outdoor temps are the same as the groundwater, geothermal systems aren't as efficient because you are powering a water pump vs a fan. In climates with 3 or less seasons, geothermal systems aren't as efficient, especially if they are closed systems. Now to answer your question, the innovations which are increasing the efficiency of geotherm systems are the same innovations which are increasing the efficiency of standard air exchange systems. Most of the energy consumed by a HVAC system is being consumed by the the refrigerant compressor and advances in compressor motors is allowing for much greater efficiency.
- Q: you know the more velocity in pipe in a heat exchanger gives the more Reynolds and then more nusselt number that is mean more H(convective heat transfer coef.) there for we expect to have more loss in hot water that is in pipe( after increasing velocity) but in experiment we are seeing less loss in temperature..why by increasing velocity (debye) we dont see more heat transfer?
- You need to do a heat and material balance around the complete exchanger to determine if there is in fact more heat being exchanged even if the hot water is not getting cooler. Remember, there is more mass of hot water passing through the exchanger so more heat could be exchanged without the temperature going down.
- Q: can i use the pool heat exchanger from a h150 with a hayward h200 pool heater?
- I've never tried, but if it fits I would assume that the exchanger on the smaller model isn't rated to work with the BTU output of the larger model. Double check though and make sure. You can visit the Hayward site and look for replacement parts for each of the heaters, this will tell you what they are each rated for and will usually give you dimensions. Sometimes it's as easy as looking up the part and comparing part numbers... some of them are interchangeable between different sizes of heaters.
- Q: I was wondering if I could put a heat exchanger behind a refrigerator to heat water. I heard that they give off a lot of heat will this be enough and is this feasible. Also would this be efficient?
- A refrigerator would only give off enough heat to heat a very small amount of water, and probably not very hot at that.
- Q: What is a shell and tube heat exchanger?
- Greatly improving the efficiency of heat transfer, in 2012 also gradually spread in the domestic market. Shell and tube heat exchanger, spiral tube bundle design, can maximize the increase in turbulence effect, increase the heat transfer efficiency. Internal shell and tube asymmetry design, the maximum can reach 4.6 times.
- Q: Just an idea that occurred to me during a conversation today. Solar energy is becoming pretty trendy these days, and it seems to be that with how hot roads get, they are basically solar panels. Admittedly thermal rather than electric, but would it somehow be possible to turn this heat into electricity? It seems to be a rather vast untapped resource if so.
- Yes, blacktop absorbs heat. To convert heat into energy, you will have to heat a fluid like water until it turns into steam, and steam can drive an electric generator. This is not working with hot roads. Solar panels are more efficient. Or look up what a heat pump is. That may do very little. If you cannot afford solar panels to generate electricity, you can use the sun to heat up water which you can then use for showers or washing. But to get that heat from roadbeds may not be so efficient. Keep thinking, though. Your next idea may be a very good one!
- Q: Are there any differences is performance letting the hot fluid flow thru the inner pipe and the cold fluid thru the annulus and vice versa??
- they're an economic determination for small exchangers that would desire to easily require some accepted tubes. they're additionally a sturdy determination for smaller intense tension applications. the alternative is often one in keeping with economics. there is not any rule that determines the determination technique.
