Hyundai Verna Egypt refrigerant mass

شحنة فريون هيونداي فيرنا

Hyundai Verna Egypt is the second generation LC (1999-2005) of Hyundai Accent sedan 4-door as I figured out from the following link in Wikipedia:
https://en.wikipedia.org/wiki/Hyundai_Accent

The refrigerant type and mass is not stated in the last updated owner's manual (2005) in the following link:
Hyundai Accent 2005 owner's manual

As I knew by asking people and by internet search the refrigerant used in the air conditioning system is R134a which is used in refrigerators and freezers, but I was not sure of the accurate (design) amount of refrigerant mass (charge) because of different values stated in different sources:

Reference 1:
http://workshop-manuals.com/hyundai/accent/l4-1.6l/heating_and_air_conditioning/refrigerant/component_information/specifications/capacity_specifications/

R134a (600 ± 25 g)

Reference 2:
http://www.techchoiceparts.com/refrigerant-and-oil-capacities/hyundai

R134a. 20 ounce = ‪566.9905‬ g.    Oil PAG46. 6 ounce=‪170.0971‬ g

Reference 3:
http://www.naasltd.com/Resources/FileBrowser/Media/Documents/CVS/Refrigerant%20and%20oil%20charge%20chart.pdf

R134a 0.600kg OIL ISO46 150g.

Reference 4:
http://www.autototal.ro/dmdocuments/Catalog%20Behr%20Hella.pdf
R134a 550 gm. Oil: PAG FD46XG 180 mL


Then, from previous references, it seems that the maximum possible amount of refrigerant charge R134a is 625 gm and oil 180 gm. This means that a 1-kg refrigerant bottle is fare enough for the refrigerant charging operation.

Air conditioner "I feel" mode

Tags:

Air conditioner "I feel" mode does not work

Air conditioner "Follow me" mode does not work

Air conditioner "Remote sensing" mode does not work


Most of us have an air conditioner at home or at work with remote-control. Most (or may be all) new air conditioners have an option that has different commercial names: "I Feel", "Follow me", or "Remote sensing". Old split-unit air conditioners had only thermostat in the return grill of the indoor unit, but now with the remote sensing option it has an additional temperature sensor in the remote controller, so the AC operating rate will be based on the local temperature of the remote which is beside or near the user. In other words, the remote sensing feature conceptually aims to achieve set temperature in the local area of the user, not the entire room.

Unfortunately, most remote controllers connect with the indoor unit using Infra-Red IR. This is a huge problem for remote sensing. That means the remote controller should be close to the indoor unit and should also be pointing to the unit which is not practical at all. Most of us don't know this trick, so we always face the problem that the AC does not stop although the room is extremely cold. 

This because when the remote controller senses that the set temperature is achieved, it can't send this data to the indoor unit because of random placement of remote controller in any place. The following illustration show the cases where the "I Feel" mode does not work.

Amazon Echo review

I heard lately about a device called Amazon Echo which is designed by Amazon company. I searched over the internet and see tens of review videos and articles about it and have the following conclusion:

Amazon Echo is a cloud-connected device which means that it relies on the internet to upload voice, convert it to text, find the answer as text, then download this narrator voice to the device again. Therefore, it is highly recommended to have a relatively fast internet connection to feel it responsive in real time.

For sure, one good point about Amazon Echo that it depends on the cloud which makes it easier to develop and get smarter with time.

It is mostly rare to pick up amazon Echo in safari trips or on beach as it needs both electricity and internet and in this case the smart phone wins.

Amazon echo is designed with 7 microphones, so it can captures voice well even if the talking person is relatively far from the device (they call this far field technology)

As a speaker, I think it does not compare with home theater or high wattage subwoofers

  

From my point of view, I don't feel it special because a smart phone application can do the same job of assistance.

The Amazon Echo, is always connected to power source which limits its portability across home rooms. Therefore, it should be used in fixed place as a piece of furniture near a power supply. Even if Amazon added internal rechargeable battery for it, it will still need to be recharged frequently.

For sure, it will be quiet profitable for Amazon to make you have at least one piece per room.

Among most of reviews, the best place to use Amazon Echo is the kitchen where you can ask it to add items to shopping list, add tasks to "to do list", and play music while preparing food.

It can also do basic functions like timer, alarm, reminder, calculator, currency and unit converter, etc.

It does not have too much useful applications in real life. I personally find this device so much funny for lonely or introvert people.

Amazon Echo is an input/output device, but it will not act at all unless you give it an input.

One good point, that Amazon Echo always stand by and available for everyone at home. From the other side, it can be used only by one person at a time which makes smart phone wins also this time.

If Amazon Echo is used as a friend or a family member, then it will destroy the relation between family members.

In all reviews, most of people were asking Amazon Echo many general questions, and it successfully answered it, but these questions are so basic. It can be used for basic internet searches and for sure it is not that useful for professional who are seeking deeper details.

If Amazon Echo has an LCD, hologram, or projector display I will feel it more entertaining than the current situation.

Amazon Echo is always hearing you, so each time you want to keep your private conversations away from being uploaded to the cloud you have to mute it.

For me, it is a silly thing to know that Alexa (the name of Assistant in Amazon Echo) has the same synthetic voice and gives me the same tonality and answers as if someone else asked.

Cool Effect: How to convert picture to monocolor in Powerpoint

A quick tutorial in PowerPoint to make a cool effect for pictures.

(1) Insert a a transparent background .png image in PowerPoint. In my example I use the following image. Alternatively, you can insert a picture and remove its background.

(2) Select the picture then go to Format - Adjust - Color - Picture color options

(3) Set the brightness of the image to 100%

(4) Now, all colors are converted to white

(5) Again go to Format - Adjust - Color and select one of the "Recolor" options.

(6) Here you are the result as you can see in the picture below:

(7) Enjoy...

This effect may be used to create shadow boards for hand tools for 5S. So you can arrange your tools and create and preview your custom shadow boards on PC, then print it on paper with the proper size (A4 to A0). Additionally, you can export the shadow picture (after re-scaling it) to any CNC cutting software to cut your shapes precisely on foam piece to make foam insert. Also, you can convert the monochrome picture to scalable format using any software or online service. For me, I use www.picsvg.com which gives good results and details.

PowerPoint VBA: How to get shape name

This is the simplest ever way to know shape name in PowerPoint so you can use this name in VBA code:

[1] Open animation pane

[2] If you already have the shape, select it, and add any animation effect to it

[3] You will see the shape highlighted in animation pane with its name.

[4] Delete the animation effect.

[5] Done...

This methods works for shapes, images, and textboxes.

PowerPoint VBA disappear animation effect

PowerPoint msoAnimEffectDisappear

Power Point msoAnimEffectDisappear

Without any complications, PowerPoint has four group of effects:

[1] Entrance effects

[2] Emphasis effects

[3] Exit effects

[4] Motion paths

PowerPoint has a list of animation effects names that you can find in the following Microsoft page (by the way, some of them does not appear in the GUI of PowerPoint, so you can call them by VBA):
https://msdn.microsoft.com/en-us/library/office/ff744314.aspx

The tricky part is that there is no exit animation effects in VBA because exit animation effect is just the reverse (opposite) of the entrance effect (see the pictures below and compare). In other words, there are set of animation effects that can be configured to be "Entrance" or "Exit" where the default configuration is "Entrance".

That means -in our case- there is no "Disappear" effect to be called by effect name like "msoAnimEffectDisappear", but it can be called by configuring the effect "msoAnimEffectAppear" to be "Exit".

The following macro adds "Disappear" effect to shape number (1) in slide number (1)

Private Sub AddDisAppearEffect() Dim Shape1 As Shape Dim ShapeEffect as Effect Set MySlide = ActivePresentation.Slides(1) Set Sahpe1= MySlide.Shapes(1) ' Add the appear effect Set ShapeEffect = MySlide.TimeLine.MainSequence.AddEffect _ (Shape1, msoAnimEffectAppear, , msoAnimTriggerAfterPrevious) ShapeEffect.Exit = msoCTrue      ' This line to configure the animation to be exit effect End Sub

Now, I think it is done. Stop googling this again :)

Smart phone stroboscope tachometer

Today, I searched over the app store for a stroboscope tachometer application to visualize oil flow and splash pattern in transparent hermetic refrigerant compressor model (typically its motor RPM is around 3000 rpm or 50 Hz) by seeing stagnant images. The idea of this category of applications is using the phone flash light as a stroboscope light and blinking it using the set frequency to act like stroboscope.  

I downloaded "Stroboscope tachometer app V 3.2" on my Lenovo A7000-a smart phone and I calibrated the stroboscope app with non-contact tachometer UNI-T UT372 and I got relatively amazing results. Since this non-contact tachometer captures the edge rise of the reflected light from the rotor, then it was good for calibration for this stroboscope app.

For my smart phone, the app worked fine up to 1000 rpm with high accuracy. By increasing the RPM the error increases in diverging way. At higher RPM values more than 1500 rpm, the application can't exceed the value of 1500 rpm with fluctuation in RPM values (this may be due to processor speed of the phone and I guess it can generate higher values on other phones with higher processors frequency).
