Piston sizing help Hi all: I am getting conflicting information from contractors about the piston orfice size they feel best using for my retrofit system, and I would appreciate your input as comparison to make the best choice between installers. The other guy maintains that regardless of efficiency.
PDF Their information supports contractor 1, but of course I don't know if it applies to all coils or their specific model. I realize this may be a murky subject, but any help would be appreciated as our install window is rapidly approaching, AND it's getting HOT! Thanks to all in advance.
Anytime you mismatch, who knows what is right. Coils are different sizes between brands so hard to say what size is right, what Tempstar calls for with their unit or what Nordyne wants for theirs. When getting into higher SEER, muddies the water even more. Best option is have an expansion valve put on the indoor coil and a Nordyne outdoor unit.
Otherwise, it's all a crapshoot. Originally Posted by mrfr0gz.

Superheat is the gas temperature above the saturated temperature. Superheat can be split into two types of heat: 1 Superheat of the evaporators and 2 Total superheat entering the compressor.
The evaporators superheat must be figured at the evaporator outlet not at the compressor inlet. Total superheat is figured at the compressor inlet. I agree get rid of the orifice and use TXV!! If it was a matched coil, the piston that teh OD unit recomends would be the right size. A TXV will be be for mix match. Contractor locator map How-to-apply-for-Professional How many times must one fix something before it is fixed?
On the nameplate on the condenser it will tell you what size to use. Or it will say TXV. That is the correct size to use. You match a piston to the condenser, no matter what coil you put on. I would recommend a TXV valve at any rate. Well, that brings up a prior decision that was phased out, with the explanation that it was more trouble than it was worth because in a residential application, we'd never notice the difference.
From the concensus here, that would seem otherwise It's too bad he was never able to follow through with his commitments and I had to move on to keep things on schedule, because he sounded the most up-to-date with progressive practice in the field. Although using a TXV may be more efficient and trouble-free from a functional and installation standpoint, I was under the distinct impression that the price range for parts and brazing R costs separate would put me just shy of a new A-coil with a TXV already installed, and therefore not really worth the gamble it would work well.
Is that a fair assumption? BTW, Thanks to all for your input, it is much appreciated. I have referenced this board for many months over the course of the last year, and find it highly informative. A no pricing questions, it in the rules. Please edit them out.
Second, the TXV will help protect the condenser in mix match systems. So its a small price to pay to help prevent paying more then double that to change out a compressor.The map with all the details on it was so helpful.
We espescially liked the extra comments like "great homemade ice cream" (it was great. With all the information in our itinerary as well as the "Icelands Highlights" portion of the "book" we were able to see almost every item in them.
We travelled with ease.
We have already recommended Nordic Visitor to friends who are thinking of going to Iceland now that we have told them how beautiful it is.
We did tell them "dress warm". We were not disappointed. The hosts were all friendly, engaging, and a delight to talk with. The accommodations ranged from newly constructed to buildings more than 100 years old. Many buildings were re-purposed from their original use to accommodations for travellers which was rewarding to see. All the the accommodations were licenced which is a measure of ensured quality. All were clean, quiet and provided excellent breakfasts. The car rental was without hitches.
When booking the tour we upgraded the car from economy to compact (a Citroen Cactus) as from our driving experience in northern Canada we knew a larger car is better on some roads. We made the right choice and our overall experience with the car was very positive. The vouchers supplied by Nordic Visitor were all recognised by the service providers.
Our reservations had all been made and no difficulties were encountered. I would like to thank Hafdis for her assistance in our trip planning. Her patience and prompt replies to our queries prior to the trip was very much appreciated, and the optional ideas she offered were helpful. We enjoyed meeting her personally at Nordic Visitor HQ on our return to Reykjavik, to share some of our experiences. In general, we were pleased and impressed with the trip planning and the travel package that Nordic put together to make our road trip so relaxing and enjoyable.
Every detail was looked after. The voucher system worked efficiently at hotel check-in, shuttle services and anywhere else ticketing was needed.
Thanks NV for a great Icelandic experience. Over all the tour was amazing. We were able to modify the 7 day tour to 9 day tour. At our face to face meeting, we discussed the Blue Lagoon and decided it was best to go there on the last day on the way to the airport. This was taken care of right away away, Our vouchers were emailed and printed at the hotel for us.
Overall the whole experience was perfect. You took the stress away of laying out out route and suggested options. We used the map, the GPS and the road guides often.
We reviewed them each night to plan the next day.Creating a logistic regression is a process that can take just a few seconds or a few days depending on the size of the dataset used as input and on the workload of BigML's systems. The logistic regression goes through a number of states until its fully completed. Through the status field in the logistic regression you can determine when the logistic regression has been fully processed and ready to be used to create predictions.
Thus when retrieving a logisticregression, it's possible to specify that only a subset of fields be retrieved, by using any combination of the following parameters in the query string (unrecognized parameters are ignored): Fields Filter Parameters Parameter TypeDescription fields optional Comma-separated list A comma-separated list of field IDs to retrieve. To update a logistic regression, you need to PUT an object containing the fields that you want to update to the logistic regression' s base URL.
Once you delete a logistic regression, it is permanently deleted. If you try to delete a logistic regression a second time, or a logistic regression that does not exist, you will receive a "404 not found" response. However, if you try to delete a logistic regression that is being used at the moment, then BigML. To list all the logistic regressions, you can use the logisticregression base URL.
By default, only the 20 most recent logistic regressions will be returned. You can get your list of logistic regressions directly in your browser using your own username and API key with the following links. You can also paginate, filter, and order your logistic regressions. If every weight does end up zero (this is possible with sampled datasets), then the logistic regression creation will fail. Clusters can handle numeric, categorical, text and items fields as inputs: Numeric fields: the Eucledian distance is computed between the instances numeric values.
Categorical fields: a common way to handle categorical data is to take each category as a new field and assign 0 or 1 depending on the category. So a field with 20 categories will become 20 separate binary fields. Text and item fields: each instance is assigned a vector of terms and then cosine similarity is computed to determine closeness between instances.
Each cluster group is represented by a centroid or center that is computed using the mean for each numeric field and the mode for each categorical field. For text and items fields each centroid contains the terms or items which minimize the average cosine distance between the centroid and the points in its neighborhood.
To create a cluster, you can select an arbitrary number of clusters (i. You can use scales to select how each field influences the distance measure used to group instances together. You can also list all of your clusters. That is, no special scaling is used. With this argument you can pick your own scaling for each field. This will make it easy for you do things like balancing age and salary, but then request that age be twice as important.
This can be used to change the names of the fields in the cluster with respect to the original names in the dataset or to tell BigML that certain fields should be preferred. All the fields in the dataset Specifies the fields to be considered to create the clusters. Must be null or a number greater than or equal to 1 and less than or equal to 300. Each model predicts whether or not an instance is part of its respective cluster.
Example: true name optional String,default is dataset's name The name you want to give to the new cluster.
The range of successive instances to build the cluster. It selects the norm to minimize when regularizing the solution. Regularizing with respect to the l1 norm causes more coefficients to be zero, and using the l2 norm forces the magnitudes of all coefficients towards zero.You can get your list of libraries directly in your browser using your own username and API key with the following links.
A listing result includes all libraries in both production and development modes. It also includes read-only system library created by BigML. You can also list all of your scripts.
To create a new script, you need to POST a string containing at least the source code to the script base URL. All you need is a valid source code and your authentication variable set up as shown above. See the list of available input types. Example: "my new script" outputs optional Array A list of variables with their name, type, and optional description, defined in the source code of script, that will conform the outputs of execution. See the list of available output types.
Once a script has been successfully created it will have the following properties. Creating a script is a process that can take just a few seconds or a few minutes depending on the workload of BigML's systems.
The script goes through a number of states until its fully completed. Through the status field in the script you can determine when the script has been fully processed and ready to be used. Once you delete a script, it is permanently deleted. If you try to delete a script a second time, or a script that does not exist, you will receive a "404 not found" response.
However, if you try to delete a script that is being used at the moment, then BigML. To list all the scripts, you can use the script base URL.
By default, only the 20 most recent scripts will be returned. You can get your list of scripts directly in your browser using your own username and API key with the following links. A listing result includes all scripts in both production and development modes.
It also includes read-only system script created by BigML. You can also list all of your executions. To create a new execution, you need to POST to the execution base URL a string containing the id of the sctipt that will be executed, as well as the required input parameters defined in the source code.
All you need is a valid script id, the input parameters values, and your authentication variable set up as shown above. This should be used instead of inputs when multiple scripts are provided.There are a lot of good teams in there right now. I'm a Georgia Dawg. I see them on TV and see what kind of players they have.

Alex Gelhar: Eli Manning scores more fantasy points than Dak PrescottSure, this sounds impossible, considering the fact that Eli Manning has more single-digit fantasy point outings (five) than games with 20-plus points (two). But something tells me this is one of those weeks for the Giants. Manning, the face of their franchise for the last decade-plus is back under center.
And the Cowboys, a team with more holes than the plot of "Jurassic World," are their opponents.We have to go out there and give our best shot.

All in all, it seemed as if this would be the year we would see a more rambunctious monetary policy impulse, more dramatic gyrations in global markets, and a more turbulent climate for trading and investments in general.
Download PDF In the US, Trump floundered from one scandal and gaffe to the next, entirely failing to pull any policy levers that impacted markets even as he took personal responsibility for a stellar year in stock markets with record low volatility. Who would have thought that, 12 months after the 2016 Election Day earthquake in the US, a classic fear indicator like gold would be near-precisely unchanged.
Our suspicion is that the complacency and low volatility in 2017 will not repeat and may indeed have stored energy for a spectacular and outrageous 2018. Thus, a number of our predictions point squarely at the risk that this accumulation of excess complacency may have blown a pent-up bubble of volatility.
But do keep in mind, as always, that these are not forecasts. This could have major forex implications for the euro.

Stephan Lichtsteiner has also missed the past two games with a muscle injury and is doubtful. Mehdi Benatia returned to training and is no longer a doubt while Mario Mandzukic is now fully recovered from his injury and highly likely to feature against Inter. Giorgio Chiellini is also likely to return after the flu kept him out of the Olympiacos game.
