Q:how works a heating pump?
A heat pump works just like a refrigerator. It moves heat from one sure to another, using the compression and expansion of gases to do the work. The heat pump operation is different from that of a refrigerator, in that it can move heat in two directions. Compressing a gas to a liquid makes it hot. Vaporizing a liquid cools it. To heat the house, the heat pump compresses gas, and a heat exchanger cools the resulting liquid. The liquid is pumped to the outside of the house, where it is expanded. Outside air heats the expanded gas, which is then returned to the house. To cool the house, the process is reversed.
Q:Thermodynamics : Heat exchanger?
a). The rate of heat transfer is given by Q = m Cp dT where m = mass flow of cooling water, Cp = the heat capacity of the cooling water, and dT = the difference between the outlet and inlet temperatures. Therefore, Q = (63 kg/s) x (4182 J/kg-K) x (22 - 15 deg C) = 1844262 J/s = 1844 kJ/s. b). The rate of condensation of steam is dependent on the steam pressure and the amount of superheat. Assuming saturated steam at 1 atm (1.01325 bar absolute), the heat balance is: Q = m * Cp * dT + m * Hv. Here m = the rate of steam condensation, Cp = heat capacity of water, dT = difference between the saturated steam temperature and the outlet condensate temperature, and Hv is the heat of vaporization of steam @ 1 atm. So Q = m * ( 4182 J/kg-K) * (100 - 30 deg C) + m * (2257000 J/kg). Solving for m yields 0.72 kg/s. Alternatively, you can use standard steam tables to obtain a more accurate answer.
Q:How can a carbon monoxide leak occur?
CO has no smell. If you are smelling gasoline, then there may be a obstacle there. The oven will not be burning the gas accurately and wishes to be adjusted and examined for safety. In case your smoke alarm is also a CO alarm, sure, that could be the predicament. But if it's only the smoke alarm, that is bizarre and more commonly still tied to unseen burned on yuck that is developing sufficient smoke in your ultra touchy oven to burn. You may also need to so some study on areas that still is also soiled and want cleansing. But with the aid of all way!!!! Name the oven repair individual, and so forth when you scent gas...And discontinue utilizing the oven except you get it fixed. It perhaps only a simple adjustment.
Q:How do I know how many heat exchangers to use?
The general rule is for the outlet temperature of the fluid being cooled to approach the inlet cooling medium by about 10 to 20 degrees. The usual way to do this is to try different size exchangers until you get to the economic limit in terms of cost for the exchangers. Most of the time you would try to use only one exchanger because that is typically the most cost effective. Also in the real world you typically have the outlet temperature of the fluid being cooled set by the process and you adjust your design to meet this requirement.
Q:What's the fastest way to defrost and defog cars?
You can always entertain the idea of replacing your heat exchanger for a more effiecient one for take the car in to check and see why it is taking so long for it to heat up. As far as the air circulator goes, it all depend if you are trying to defog or defrost. If you are tryinf to defrost, turn it curculate the air inside the car. If you are trying to defog, cycle the outside air in. As far as the ac coming on right away, my Pilot is like that. No matter what setting you have it on, when you turn on the system, the ac automatically turn on and you have to go and manually turn off the ac. I think that most car manufacturing are goint that route. Also, I would not recommend adding anything to your windshileld fluid or spraying anything on your windshield. Adding other fluid to your windshild wiper just increase the alcohol percentage of your fluid which leads to other problems. Spay on are usually some oil base what not. In cold weather, you are going hate yourself for spraying it because it is usually the first thing to freeze. My recommendation? Get your heat exchanger and cooling system looked at because it should not take that long to heat up the car and experement with your enviromental control and see what work best for you. p/s... Dont buy any ceremic heater in an attempt to heat the car. Useless for that purpose. If you are going to go that route, I would say by a block heater instead.
Q:Accidently turned on the emergency heat what is that anyway?
You probably have a heat pump. Under normal conditions, the heat pump transfers residual heat from the outside to the inside of the house, and is very efficient. Most heat pumps have an emergency heat setting, for use when the normal equipment fails, or when it is exceedingly cold outside. The emergency heat equipment is very simple, but low efficiency. It will cost you more money to use than the normal setting. That's really about it. Normal is complicated, but very energy efficient. Emergency is simple, but will use more electricity. No harm done. For a few hours use, you probably won't notice the difference on the electric bill.
Q:DIY solar water heater tank?
A sunlight power system is a low-intensity energy source that's probably supplemented with different normal power souces,even though it may be designed to handle a hundred percent of a vigour load requirement.A passive solar vigour process does now not appoint circulators or fanatics but relies on typical(gravity)glide. One of the most principal concerns when sunlight power methods are established is the structural loading result from collectors and supports. There's a headquartered criteria for flammable and combustible warmness switch drinks in a solar collection method.That's the minimum temperture at which the liquid offers off suffucient vapor to kind an ignitable blend with air near the surface of the liquid (flashpoint).The warmth transfer fluid is required to have a flashpoint temperature of at the least 50%F above the max design temperature that it might attain at the same time flowing through the approach. That is designed on the location of where you are living and area of the air to air collector that's installed with regard to sun light. To calculate the process you must understand how much(on ordinary) of scorching water you require per day. A traditional lively space and domestic solar water heating work like this, Liquid flows from the sunlight collector to the Thermal storage water tank through the Furnace to a pre-heater to the water tank. All of your required calculations will finished for you earlier than you buy the system by the installion corporation.This will have to exhibit a financial assertion for the discipline you are living in. As at all times,get references from people on your subject who have any such method earlier than you spend money on the system. Hope this helps.
Q:what is mean by floating type heat exchanger?
In some plant operations it is possible for the tubes to get to a temperature such that they expand to a level that could cause them to buckle. In come cases a U-Tube exchanger is used to address this problem. Others the floating head type is used. Here one of the tubesheets is fabricated so the sheet can move to compensate for the thermal expansion. I can send you a picture of several types of floating heads if that would be useful.
Q:Can you put heat strips in a gas furnace?
No it is impossible, because the way Gas Furnaces are designed is to apply direct flame from the gas burner to the Heat Exchanger. Converting this process to an electric, required using Heating Elements or strips attached to the Heat Exchanger and controlled by a thermostat. Heating Elements can heat water but not Exchangers, strips might do it, but they are slow, however when we take a hot shower, we use hot water from the water heater which will automatically turn on the heating element for heating the water again, is it slow, but we don’t notice that, because we don’t use all the water heated at the tank. Using this way for a furnace will not work, because Heat Exchanger will lose a lot of heat when it radiates heat to the apartment or home, and the electric element or strips will not follow up with heat loss caused by radiation. It will require at least 20K watts worth of elements or strips attached to the Heat Exchanger in order to follow up with the lost heat, which will cost you more than the gas bill, and will be very slow to heat. If you are trying to lower your gas bill, you need to insulate your home very well; you also can use electric space heaters for each room, 3K Watts worth of heaters for an average room size will do the job, good luck….
Q:In reference to HVAC: How long should a TXV last? Is a TXV the same as a heat exchanger?
While its not common its not uncommon if that makes sense. A. The typically answer would be no, but depending on who made it then yes (that is brand of equipment) B. No the TXV is a thermal expansion valve, the heat exchanger would be for the gas furnace part. C. Cost depends on labor charges. Its a 2-3 hour job. It awful high to me. The warranty ONLY covers the part not the labor. Unless you bought an extended warranty that pays labor. So, the part its self is Free. Everything else is not. But, lets do some number working here. Lets just say THEY say its 4 hours. 4 @ 90 is $360 dollars. Throw in some misc stuff 50 bucks. That puts you around the 400ish. The problem here is you need a detail quote from them that breaks down how they got to the 650 bucks. I mean yes, they are replacing the TXV which is free. Are they doing a total evacuation of the refrigerant? Or simply shutting off the service valves, and recovering the gas thats left over in the line set / evaporator coil? Personally thats too high if you ask me. but I dont know where your at. But thats about a 400 deal out the door. Call another company and ask them to give you a quote over the phone. They dont need to look at it. Just give them the make and MN# SN# of ac unit outside. They should be able to tell you that A. the TXV is a warranty part. And the labor + tax = xyz.
