Refrigeration Design Software - Coolselector 2

[Applause] hello guys Paul here from the engineering mindset calm in this video we're gonna be looking at refrigeration system design using the cool selector to act by Danfoss now this software is really quick and easy to use which makes it perfect for HVAC professionals and students you can really quickly just check the retrofit compatibility of a system you can compare the performance of the system if you were to replace some of the parts you can design almost any refrigeration system in there and there's even some wizards built in such as a cold room wizard so just a few clicks of a button and it will come up with all the components that you need for your cold room storage and once you've done all that it provides all the design data the graphs and a very professional-looking report best of all this software is absolutely free so it's well well for download just having a play around and test some of your HVAC knowledge guys I'd just like to take a moment to thank Jane Foss our sponsor for today's episode dan Foss is your go-to source for information and resources that they can help you through the cooling industry's transition to natural and climate friendly refrigerants they have a deep understanding of all the new regulations and their effects and they're ready to share their knowledge and solutions with you they've also made helpful tools like the refrigerant retrofit guide the low GWP tool and also the cool selector to app which is available for free on their website you can access them now by visiting refrigerants dan Foss comm installation of the software is really quick and easy just head over to cool selector Dan force comm scroll down you see the download link let that download and you see it appear down here and just click it to open it and start the installation going to do an English obviously it through scroll through the terms and conditions if you accept it then go forward yeah we'll have the icons created as well and then done now we'll come straight to which country you're in units you can have international si or American or realistic with international units and the applications you can if you want to just specify only commercial applications or industrial applications but I'm gonna stick with all of them so we'll just continue and then it will low to a screen like this where you've got all your different options and components available now right at the very top on this plane here we've got the our option and obviously we can load and save and open projects or even send them we can check the reports of them and also the Bill of Materials we go into options we've also got the Preferences so again you can change these from commercial-industrial all applications again you can change the units from SI international and American or even customs go back and change the user and the language in the country from the initial setup and also change the style if we go into tools and you can see the operating conditions or we'll say the products and refrigerants overview and then just in the about we've got a little a few learning content links there and also the updates now there's a few different design options you can select from and the first one being the valves and line components so this is more if you want to just replace a single component within the system or see how it might perform with a different refrigerant in there etc etc then this is the option you want here so you can just go through and select the single component that you want to replace let's say solenoid valve so we just click that one and then the first of all it's going to ask you do you want this to go on the suction line the discharge line or the liquid line will select liquid and then I'll ask you to specify the refrigerant and I'll just leave that as r134a in this circumstances then it's going to ask you about the cooling capacity you can obviously change these values and then it asks you the temperature for the evaporation and the condensation as well as the superheat and the sub cooling so you can change these two to suit your parameters and then it's going to ask you do you want to select the components based on pressure drop or the velocity will stick with velocity and then it's also going to ask what type of connection would you like to go with this so from that we can then choose a product line and it will then make recommendations and let's say if we selected these ones and as we go across it's coming up with some warnings they're telling us that there's going to be flashing in this liquid line so these valves are not going to be applicable for our installation let's go with a EVR version two and you can see the ones which are in red are the ones which have a warning against them again it's going to have flashing but these the options here the ones which are applicable to our installation so we can select from a few different options here and you can see this line here which is highlighted in green that is recommending that this product is the best option for your installation so we'll select that one and then further down the bottom here you'll see it also provides the performance curve for this product and that's got your pressure difference on one side and your cooling capacity going along the other axis and one feature which I thought was really useful in here actually so it gives you your diagrams here for the for the system but also over here it's going to give you all the for the around the entire system some of your design criteria in there so it's even including the enthalpy and entropy and the density as it's moving around the system you can see a great deal of detail has been included with this this selection software so the next part we're going to look at is the components in series option and this will give you all the different systems which you can design through this software and not just that it would also let you go and just design the specific line part of of the system so if we got the basic refrigeration cycle here and it's asking do you want to design the suction line the discharge line or the liquid line and we'll just go through with the liquid line once it's loaded they'll asking you which type of refrigerant would you like to use first of all I will leave it as what r134a and then it's gonna ask you about the cooling capacities and also the temperatures for your evaporator and condenser so that's the superheat and the sub cooling and then you can also change from all the different selections and sizes or connections and sizes even and then over here you've got the components which you can select from so as we've got the evaporator and the condenser then before the evaporator we're going to want a expansion valve we've got the electronic over here the thermostatic or the manual I'll just go with the thermostatic for this one and let's just say I'll just click this first one the TT and we'll drag that in but what you'll see is that the results is telling us that the capacity of this valve is going to be too small for our application so we'll just close that one is it's not applicable for what we want so we'll select the thermal expansion valve again and let's just go with the tge product line and we'll add that in and then straight away you can see that the connections is fine and the results are fine so we can go with this one next we're going to want to add in a filter drier so we'll come through and you can select all the different product lines here again I'm just going to choose DML and I'll drag that one in there and we can see that the connection is okay and the result is it is applicable to other system with designing although now you can see the connection is not the same the connection is not suitable for this thermal expansion valve but that's fine we'll look at that and correct that towards the end so we'll also want to add in a sight glass let's just select this one here and I think we'll just go with the SG line so we'll stick one of these just before the expansion valve again you can see that it's applicable and the connection is good so then we want to add in some ball valves so we'll just select stock valves and we'll find the ball valve so we'll add one of these either side of the filter dryer again you can see that the connection is good and it is applicable to our system and then we'll add in a bit of pipe piping Xandra straight piping so it just used copper pipe and what add that let's just add that before the filter dryer we just move that to this side of the system and then it's given us the option would you like to change the length of the pipe so yes we'll just add in one meter for that one and it's asking about the angle of the pipe so zero being horizontal and 90 being vertical and you'll see the icon will change there as well but I'll leave that as zero now you can also see that this next valve and the ball valve has come up and said that this is not applicable the connection is not applicable it can't be used with this one so we can saw that by just clicking on here and we'll go through and we'll choose size 10 because that's at size 10 so and now all the connections are to find that a connection that will fit between the expansion valve and the sight glass we're just going to choose an expander and we'll clicking drag that in and a great feature with the software is that this will actually just automatically size it to for the components so you can see that this was a 10 and this is a 12 and so it's giving us a copper expander which is size 10 to 12 and down the bottom here we can just pull this section up and they'll give you performance curves and also give us the performance details and gain a feature I really like with this software and even better than that it'll also give us the code numbers we need and the product line so you can take these straight to down fast and say design this system these are all the components I need in addition to that you can also now take this report or this design and put it into a report very professional-looking and it'll come off and as you go through it'll give you all the design criteria that you've specified for your design and then I'll tell you for each of the components as well including the pressure drop and the velocity etc that's going through there absolutely fantastic we've got all the different components in there and at the very bottom we'll also see we've got the performance curve as well all right so the next thing we'll look at is commercial applications and in there you can see we can do the design for a cold room so we click on there you'll see this pop-up appear and it's gonna ask you would you like to manually design it or go for a wizard we'll just go with the wizard and it's gonna ask you about the dimensions and the operating conditions for the cold room so we'll just leave it as default again you can choose which type of goods you've got in there I'll leave it as mixed and then we'll continue it's going to ask you again about the the temperature the humidity in the operating hours and the type of insulation that you have so once you've selected them go forward and there's going to come up like this and they really include a lot of detail in there so you can still change the dimensions if you haven't wasn't quite right and also the operating conditions and the goods you've got in there then you can go through the infiltration for the arocs as well as the heat transfer you can choose you know the different thicknesses of the insulation and also additional load so if you've got some lights in there which can add a bit of heat etc you can go through and you know look at here you've got you can even add how many people will be working in there or other if you know what the watts are going to be so you can add all those in there and we'll just go forward you can select the where in the world this is going to be I'll leave it as Europe and then you can choose from the different types of systems that you've got there and also the different refrigerants that you're going to be using so we'll leave its default and just continue there's going to ask you about some of the components in there we'll just leave it as that is and select that and when it loads it'll come up and it'll done all the work for you so you know which condensing unit to use which controllers you will need to use you know the pipe work the different valves the expansion valves and the distributor you've got there and also the pipe work which you need so this has done all the legwork for you it's just very quick and easy and that you've got the whole system plan for you he gained from there you can go straight into the report and we can just scroll through it'll come up with all the design design criteria which we just looked at and the pressure drops etc that you're going to be facing with that so the next part we'll look at is the industrial applications and in here you can see you've got the evaporative valve station so we'll just select that and it'll come up with that let's pop up here then you see we've come up with the bow selection box here and we've got all the different lines which are coming in and you've got a few options here for which type of connection you would like I'll tell it to include pipes and we'll leave everything else as standard and as we go through it's then gonna ask you what is the distance between the evaporator and the box and we'll leave it as free metres then it's going to come out with some more design data here so you can obviously choose the refrigerant which we're going to be using in the system and you can change the cooling capacities and the temperatures so I'll just leave that all as it is and that will then load and inside you've got all the design criteria that you need so these are all the components it would have selected for you to meet the design criteria that you need and then you can just quick and easily click on report and generate this professional-looking report for you and this contains your diagrams as well as all the components and the design criteria that you've included in there and you can that's ready to then go into your site pack or off to the to dem faster purchase the components that you need and the last section we'll look at is the compressor that in condensing unit section and so you can just select an individual compressor or condenser unit for your system and we'll just go and look go in and have a look at the compressor section so when it loads you'll see all this information that's come up here and you can choose what sort of system you look would like so let's go for just refrigeration so we'll deselect heating mode then we'll choose which type of refrigerant we're going to be using and we'll select just let's go with for 10a and then you can choose the power supply so I'm in the UK I'm going to use 50 Hertz if you in the US etc then you'll use 60 then we'll look and we leave both reciprocating and scroll in there fix speed or variable speed and cooling capacity we'll leave as it is as well as the evaporator and condenser and the superheat and sub cooling that come with them and then as we go through this list here we can see the the percent maps that we've got here so these two here the most ideal ones and it's recommending you can see this one highlighted in green that this would be for the design criteria that I've put in this will be the most applicable and suitable for the needs so we'll stick with that one and as we lift this up you can see we've got the performance curves here the working envelope performance details and some more information on the selection and if we go to the performance you can go and see that we've got all the different charts so we've got the cooling capacity depending on the evaporating temperature and the cooling capacity and we've got the power consumption based on the evaporating temperature the heating capacity the mount of currents is going to use the coefficient of performance and the mass flow rate which it can provide depending again on the evaporating temperature and again then you've selected this and we're happy with using this in our system we can just head over to reports and it automatically generates a nice little report page in there telling us we you know which would progress reviews and some of the design criteria that goes with that alright guys that's it for this video thank you very much for watching I hope you enjoy that and it helped you just before we go I'd like to say one more quick thanks our den Foss for sponsoring this episode
