DIY mini split compressor in basement INTRO

My name is Omar Lutfey I have created Lutfey Innovations to develop better heating and cooling systems today I’m going to explain our plan to install a heat pump in an existing home to increase heating and cooling efficiency a 3/4 ton 9,000 BTU power mini-split air conditioner and heat pump will be installed to supplement the existing forced air system while heat pumps are very efficient as they exist today we are testing a new installation which we believe will even further increase efficiency traditionally the compressor unit of a heat pump is installed on the outside of a building on this project we will be installing the compressor unit in the unfinished basement of the home this configuration will allow the unit to exchange heat with a constant supply of 55 degree air in the summertime the unit will draw less power adding heat to the cool air of the basement compared to the 100 degree outside hair in the wintertime the unit will remove heat from the 55 degree basement instead of from the freezing outside air in addition to increasing efficiency this setup will keep the compressor unit in a controlled environment this should increase the life of the unit as it will be stored at a constant temperature and not exposed to rain and snow our next video will show the installation process and measure the efficiency of the unit thanks for watching

Roof mounted AC (Package Unit) vs Split System

Roof mounted AC (Package Unit) vs Split System

“Make a precision decision with Precision Air. Trained professionals with integrity. Call 602FIXMYAC. Make a precision decision with Precision Air.” Hello everybody. Erik Bryan here, owner of Precision Air & Heating. Since 1995, we have performed well over 250,000 service calls across the valley. We thought, what better way to share our experience and know-how than answering some common homeowner questions. Matt from Phoenix asks, “Erik, if I get an A/C system on my roof, is it more expensive?” Good question Matt. The reality of the situation is this….the cost between a package unit on the roof and a traditional split system on the ground or in your closet or attic, should be identically the same. Now a couple of key points to note here is that the installation of a split system is typically more difficult.

Getting air handlers to fit up in the attics or getting an air handler to properly fit inside a closet or a cabinet that you might have, can sometimes be a challenge. The instillation of a package unit on the room is generally just a good, old-fashioned stand, an elbow….a crane comes in and drops the unit down…button it up, hook the electrical up…it’s really pretty simple. To answer your question, the cost between any type of equipment should be the same. Hopefully that answers your question Matt. Thank you for sharing your questions. I hope this helps shed some light on keeping your home operating properly and as efficiently as possible. If you have questions regarding your A/C, heating, plumbing, or home performance needs, post your questions on our Facebook page and check back for additional videos. Who knows, we might just answer your question next. “Make a precision decision with Precision Air.” .

How Forced Air Central Split Systems Work – Younits.com [HD]

Let’s talk today about what makes up a split central system for heating and air conditioning it’s described as a split system because it consists of indoor equipment and outdoor equipment which is connected by a pipe known as a line set the indoor equipment would consist of a gas-fired furnace or an air handler the outside equipment would be a condenser unit and also could be a heat pump the gas fired furnace is going to produce a flame which is going to heat up a wire grid that wire grid is known as a heat exchanger a blower is then going to blow that air through ductwork through the house it’s going to come out the outlets and be drawn across the room to a larger duct known as an air return this circulates the air across the room keeping the room comfortable and returns back to the furnace where the process is repeated now there are three different styles of burners there’s a single stage which simply goes on and off there’s a two stage which has a high and a low setting and there’s also a modulating which is going to be the most efficient type and that is going to increase or decrease depending upon demand similarly the blower motor itself is available as a multi speed low medium or high settings or variable speed which again will be the most efficient method of operation it should also be noted that the furnace or air handler are available in a variety of configurations up flow units would typically be mounted in the basement a down flow unit is often used in a first floor application and in the attic or crawl spaces oftentimes we would use horizontal units these are all available in packages that are very cost effective or individual components can be purchased separately to customize your installation to make it most effective and efficient during the cooling season the condensing unit outside is going to have refrigerant pipes which is going to transfer cold refrigerant back into the house and it’s going to go into an evaporator coil which is there going to be in case or on case on top of the furnace unit itself when it goes to the evaporator coil cold air will be transferred while removing humidity from the air this blower motor will again Tran it blow this cool air through the outlets and across the room and return back to the unit to complete the process a heat pump operates in the same manner for the cooling it does have a distinction in the wintertime it is able to produce heat ironically it takes cold outdoor air and compresses and condenses that outdoor air to generate heat and that heat is transferred into the furnace unit itself from where it is carried throughout the house there is another type of system known as a hybrid the hybrid system actually incorporates a heat pump and also a traditional or conventional gas fired furnace the advantage of this is that during more moderate times the heat pump can be used which is a more cost-effective way to deliver heating and cooling because it just runs on electricity alone during times when it exceeds 40 degrees and gets lower than that the furnace would automatically kick in you don’t have to manually adjust that and therefore the furnace could deliver a greater volume of heat in times when there’s greater demand check out all the components that are available from units comm y-o-u and i TS comm you

What’s Inside A Filter Drier – How it works hvac

What’s Inside A Filter Drier – How it works  hvac

Hey there guys Paul here from the engineering mindset .com in this video we’re going to be looking inside one of these the hermetic filter a dryer by Danfoss coming up what are they used for where do we find them and then we’ll cut one open and look at all the parts inside and discuss the purpose of each bit if by the end of this video you still haven’t had your fill of filter dryers then I suggest you head over to DanFoss learning and dive into their collection of free elessons danFoss is passionate about sharing knowledge so in addition to sponsoring this video they’ve also made hundreds of elessons available for free on their website including multiple courses on filters dryers you can find all of it by following the link in the video description down below where do we find these filter dryers this is a very typical model filter dryer and we’ll find these installed in the liquid line of the refrigeration system between the condenser and the expansion valve we’ve covered how expansion valves heat exchanges and refrigerants work in our previous videos do check those out links in the video description down below on the side of the filter dryer you’ll find an arrow this indicates the direction of refrigerant flow some models for heat pumps might be bi-directional and the arrow will point both left and right but in this case we have a single direction one-way filter dryer on the outside we have a powder painted surface which just prevents corrosion and the black gloss finish which just gives a premium look and feel the casing is made from steel to give it a strong structure as this will be under some high internal pressure out once connected into the refrigeration system at each end we have some solder connections which can either be pure copper or copper plated depending on the model so what do we use a filter dryer for well these are found in refrigeration systems and as you might guess from their name their job is to filter and dry the refrigerant they protect the refrigeration system and its components by capturing and absorbing water particles as well as harmful solid substances this will prevent them from cycling around the system and getting into the compressors that valves the sensors etc to keep the system running in optimal conditions anyway enough about that let’s cut it open and look inside of the components I’m just going to use a slit disk in the angle grinder to cut this one open I’m going to start with a fresh disc just to get the maximum cutting depth then I’ll lock the filter dryer into the bench vise to stop it moving around then we can just slice for it nice and easy with the grinder as I said the casing is made of steel so we’re going to get a lot of sparks flying around the workshop so we have to make sure we’re wearing some protective clothing and also move any flammable materials out of the way I’ve just reposition this in the vise to get my second cut not roughly ninety degrees to the first just let us look inside all right that’s the casing cut open let’s pull it apart to look inside so as we remove the casing we instantly see some of the key components inside the biggest component being the solid core but we’ll look at that in just a moment now at the refrigerant inlet end we have a large spring I’ve actually cut through this one so it has lost its shape and I can just pull the remaining parts of that out but the spring pushes against both the casing and the solid core this is just there to keep the core in a fixed position inside the casing next we have the core or the molecular sieve this particular model has a solid core 80% of which is a molecular sieve and 20% is an activated alumina I’ll show you some close-ups here of that porous material the solid core molecular structure acts as a filter to capture any large particles the material is similar to a sponge in that it can soak up and retain water the aluminium oxide is added in there to capture and retain the acids not all filter dryers will have activated alumina inside them it depends on the application so the refrigerant enters and surrounds the outside of the core the pressure of the system forces the refrigerant to pass through the porous material notice this groove inside the refrigerant will pass through the solid core and then collect in this groove to continue its flow towards the expansion valve at the end of the solid core we have a screen this polyester mat retains the smaller dirt particles which might have been able to pass through the solid core the material is able to capture dirt particles down to 25 microns with minimal pressure drop after the screen we have a perforated plate this is just there to keep all the internal parts in position the holes just allow the refrigerant to flow to the outlet the refrigerant then leaves the filter dryer and heads to the expansion valve so the refrigerant enters through the inlet it passes across the spring and then surrounds the outside of the solid core the spring is pushing and holding everything in place the refrigerant then passes through the solid core and as it does so the dirt moisture and acids are absorbed the refrigerant then collects in the groove at the center of the core and then it passes through the screen it then passes through the perforated plate and exits the unit having been filtered and dried the refrigerant then continues to the expansion valve ready to continue your education on filter dryers then head over to the Danfoss learning web page now and start your first course for free just follow the link in the video description below ok that’s it but if you want to continue your learning then just click on one of the videos on screen now and I’ll catch you there for the next
