Aha! Yes, it was indeed on the top of the oven. Sneaky.

OK the model number is AHY3300. Are we good to go?

Thanks for your reply – on closer inspection the door isn’t sealing that well. Could this be a cause of the ice forming? If so where can we get the hinges?
Thanks

Re: heat pump tumble dryer

clever dicky wrote:Hi Guys, still strugleing? It is difficult to get your head around. The whole heatpump drying business blew me away and that was after years already working in refrigeration and college.
Something to bear in mind when comparing ac and heatpump dryers is they ARE the same refrigeration process. The transfer of thermall energy from one side to the other. That said, when you then make comparisons about temperatures close to .. or nearly … the applications are a world apart.

For a start on a basic or even highly complicated and complex ac system the whole point is that there is an ever increasing temperature difference between the cold (evaporator) side and the hot (condenser) side of a system. The cold side suction gas cools the compressor. Also there is a temperature difference between ambient (outside) air temperature and the condenser coil. Lots of oppertunity to get rid of that excess heat.

In a heatpump dryer its both coils need to be on the inside. The excess heat from the condenser is used to continue heating the load. Not only that, you are still ADDING heat to the same load to evaporate the water but also from the system itself. Think of a de-humidifier in a steam room, with extra heaters and a couple of fans blowing at it. But remember if the load that your drying gets to say 50’c, your evaporator is at the same temperature. And its from all the thermal energy of the water vapour, (from the energy of condensing water vapour) of the water condensing ( that makes the whole thing so efficient) but your suction gas is going to be pretty high at 50’c and so the refrigerant is at quite a high pressure already. There are many things that can be done to help, such as additional outside coils, but it is by its nature a cruel process.

I think its completly possible without doubt to scale the whole thing down to work and fit inside a large dryer, but parts would have to be first rate. Especially with the pressures, but I think its likely that the process would be adapted to not work quite like (and so with out all the bennefit) of a large commercial heatpump (dehumidifier). My feeling is that if one does appear it will more likly appear much like a normal ‘condenser’ dryer you get now, but with only an assisted cold side on the heat exchanger. Theres even the possibility of cycling cold water through a water cooled heat exchanger to below the dew point.

Hope this helps

I am really feeling bad to understand your points. I may need to learn more theromodynamics.

We are discussing a new product which clearly has big advantage and disadvantage. The important thing we should remember is that we are not limited in current design. As I said in my previous post there are some serious problems in current design and those problems are true problems you just mentioned in here.

1. Initialy the heat pump can’t get heat back from evaporated water. So in certain time period the COP of system is near 1 and this also means it will take longer time to finish all drying process. I will think this is also the problem why heat pump clothes dryer only can decrease energy cost 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d},
Can this problem be solved? Sure it can and my main idea is to solve this problem (sorry i can’t tell it in here).

2. If your drying is at 50C and your evaporate is at 50C too?
Again you make your point based on current design.
I will say it is not. At least in my design it is not.
Even it is in this condition we still can do some work in compressor such as decreasing compress ratio.

Re: Bosch Dishwasher not draining

Hi,

I have tried Martin and Clive’s suggestions and it has not worked.

I have noted Greg’s comments about the pump but Bosch Engineers are few and far between on the Isle of Skye! How difficult is it to change?

kwatt wrote:No Mazda609, in the US you guys have the luxury of space in most homes that we don’t in Western Europe, so we’re limited by size massively. Some of the kitchens we work in you actually do not have room to test a machine once it’s drawn out and the measurements given are for a standard Euro-box as kitchens here are almost universally standard sizes. I’d guess that well over 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of washers, dryers and the vast majority of dishwashers were that size. The number of people that have space for a proper laundry room is low, although there is a market for larger appliances it is small.

However, before people here increased the size, or space allocated to laundry, they’d far rather have a large cooker or fridge I expect so the sales on a larger machine that was way more expensive would be extremely limited in Europe most likely. And, as Clever Dicky says, whilst you probably could scale the components down to make it fit there’s a lot of trade-offs to be made to achieve that which would likely make it impracticle at best to manufacture on any sort of scale.

Space in most of Europe is at a premium, very expensive and people here I think would much rather allocate any free space to other purposes.

So you will think there is no problem for heat pump clothes dryer to be used in US, right?

I whould appreciate it to do this favor for me.
If it is not that big, you can scan it by a scaner and send it directly to my e-mail(hunter191@hotmail.com) , if its too much big , just sellect the important pages like the programs detail and the opeartion steps ( and you will own me a one )

Hi: kwatt

I think we are talking about the heat pump clothes dryer which can decrease energy consumption 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} in current condition. Clearly there are some problems. One is high price and other one may be performance (i think) etc. There is no doubt that the size is problem too because you have to add several parts (like you mentioned).

When we talk some new things we can’t limit our eye to a small area. I never think the size is an issue which will kill this product.
1. If there is no other problem except size is too big the heat pump dryer will be a very good product, right? People who live in big house or have enough space to put this dryer will buy it. People who hasn’t space to hold this dryer will do some change in their space to try to install it. If they really have no space to put it they will not buy it. In the future the new house will have enough space (standard or optional).

2. I live in US and we have large laundry space. Many family in here have large laundry space to. IN the future many and many home can have a large laundry space if it is necessary.

Hi: clever dicky

I think I know thermodynamics but still can’t catch your point.

1. There are no difference between narmal clothes dryer and heat pump clothes dryer to heat washing. It do need a lot of heat to heat washing first and then evaporate water but this happens in the traditional dryer too.

2. The heat pump dryer has to provide enough heat (QUANTITY you mentioned). I don’t know why you said this is a problem. AC provide those heat which can be far more.

3. You said “Much higher temps and pressure than any ac will ever deal with”. I do remember you mentioned a 90 C dryer chamber temperature. I think the clother dryer drum temperatrure is lower (I did measure a small commercial dryer chamber temperature and the max temperature is about 75C and the dryer stays in about 40C for most of time). The AC condenser design is very simple and it can get air to 50C. If you design the condenser for clothes dryer this air temperature can be high (above 80). So I don’t think in this condition machanical damage is not a big problem.

I will think this application is same as AC but need some fine design.

Hope you can point out what is wrong in my message.

Re: Hoover inter@ct

This is a sorry tale of a non resolved problem despite 7 visits from an engineer.

It took three visits before the engineer decided we needed a new control board and display board. This took 6 weeks to obtain.

This was fitted and while the controls at least appear to work it was clear that the problem had not been fixed. Our fridge would freeze solid a 4pt pack of milk overnight!

So the engineer thought the new board must be faulty and fitted another one.

…and still we have a fridge that would make the artic appear hospitable. An engineer is coming back this Wednesday. Any thoughts from anyone about possible other faults (presumably although the control is on the board the sensor must be somewhere in the workings at the inside rear of the fridge – my money ius on that being the problem – clearly the control board is not getting the right information.

The company we are using is APG. The have been friendly and polite and only charged us one call out charge and so far half the cost of the new board – but four months without a proper fridge is getting annoying for an expenditure which is already over £100.

Steve

PS why is it when I can get a rare CD from Amazon within three days it takes 4 weeks plus to get a fridge part!!!!!!

Re: Who charges what for what ??

guilt and earning a living are uneasy bedfellows!

I think you have to be cool with what you charge as its your life style and your business. However, we charge £50 + vat for a fixed price labour plus parts, if that helps.
