@@ericescuro8242 Very good vid, but, you should have shown the refrigerant as blue immediately out of the expansion valves & increasing in heat (yellowish) as it picks up heat while it moves through the evaporator coils Also, a bit about more about when it isn't economical to run the heat pump would have been good. I've lived in very cold areas & when the outside temp is too cold, the compressor is disabled & an inside heating element is automatically switched on because at some point (temp) that becomes less expensive than running the compressor & fans to heat..
Thanks very much for taking time to explain this. I am an HVAC/R student and heat pumps have been the bane of my existence for six months now. Also, I recomend the reversing valve video for anyone else who is suffering through this.
Keep at it Ms. HVAC-R and Electrical are a mystery to most humans which means there is big $$ available when failure occurs and the customer goes into panic mode.
Had mini-split system installed for my garage New England. Fantastic Summer & Winter! Very quiet and efficient. It's 12 degrees here now & this thing is quietly keeping the garage a steady temp.
I'm currently in HVAC class and we are on the subject of Heat Pumps. This was a very well done video and so helpful. The fact that you can see the flow through the reversing valve made it so much easier to understand how it works!! Thank you. I'll be sharing this with my instructor to share with the class.
It’s amazing how you explain the way it works . The boiling point I never new how or when it’s a good place for a heat pumps or a gas furnaces but seeing the boiling points now you could suggest the best thing for a costumer is .
Great selection of videos on heat pumps. Could you possibly make a videos explaining how a gas absorption heat pump works and is there a difference between a GAHP and a gas fired heat pump? Thanks.
I can't stop my brain from associating red with hot and blue with cold so the fact that the subcooling liquid is red makes this video really confusing for me. Could just be me though.
Red hose is the high side (hot side) so your brain association is not wrong.. The blue hose is low side or the "cold" side of the system where heat is removed. They call it "subcooling" because the refrigerant is below it's boiling point but existing as a liquid. High side expells heat which is why the color is red
Wow, I used to think heat pumps got energy from electricity, not the air. Motors are the only part of a heat pump that needs electrical energy? Neat how refrigerants are so easy to vaporize; the power of chemistry!
thanks for your precious and valuable tutorials... the question is that in all of heat pump explanations i saw only one expansion valve.. in some model it's at indoor unit and in other models it's at outdoor unit but here i see 2 expansion valve ? is that exists in real life ?
Hi, I want to use the AC System as Heat Pump only. It will never be used for cooling. Why do the installation guys insist I have to install the Split evaporator near the ceiling? In fact I think that installing the Split unit near to the ceiling will be less efficient because it does not use convection to distribute the heat in the whole volume of the room. Additionally, the installation on top provides warm air near your head, which is uncomfortable, and the maintenance is more difficult than a split installed near to the bottom of the wall or in the middle of the wall. What do you think about it?
Thanks for the video mate, just about to take delivery of my first BEV (Battery Electric Vehicle) which has a heat pump and was curious to find out how it works ;) I take it is a similar principle in vehicles too?
Awesome, BEV's are certainly the future. The heat pump will wor kthe same it will just use a different method to drive the compressors, usually a belt drive connected to the main motor.
I am not an engineer. I am a nurse and I want to stop using oil to heat my house. Clearly I have a lot to learn and this is a good start. I need to know how to convert my house from oil to a heat pump.
Only problem. In heat mode motion demomstration. You kind of confuse other with the line getting redder as it goes through the condenser(air handler in heat mode). It is rejecting heat into the air being forced through the house (coil). I know you are meaning to show the condensing of the refrigerant into a liquid. But to someone who doesn’t know it may seem like it’s picking up heat instead of rejecting. Btw how did u learn this? I went to School and grew up doing it with my pops
Wait you said once the gas leaves the evaporator (in home) it is low press/temp saturated vapor? I thought the only time when it’s “saturated” is when it’s in the coil and once it’s on the outlet it is superheated and not considered saturated
Nice animation. However your expansion valve operation is backwards. The valve closest to the evaporator coil (cooling or heating mode) is the one that is engaged while the other is bypassed.
Nice Video Paul. I have recently turned on my Mitsubishi Heatpump to cooling mode and I've got it set to 16 and doesn't seem to be running really cold as last summer (I'm from NZ) and outside it don't seem to be expelling a lot of hot air. Do you think it may need looking at? Cheers Mike
In general I like this video. An improvement would be to only show the gases in the narrative during their rotation around the loop or have a pointer to the gas being described in the narrative as it travels around the loop. There is another significant improvement, I do believe that the gas does not have to boil in order for a heat pump to work (just makes the heat transfer more effective when there is a phase change). For instance plain air can be used in the gas circuit. No phase change is required but the size of the coils becomes much larger because of the poorer heat transfer from a gas to the outside or inside air. The phase change allows for higher heat transfer and thus smaller coil size and a more economical construction. Once when I was a plant engineer I had an ultrasonic air leak detector technician tell me he found a locker in the tradesmen's shower area in a plant that the tradesman just connected a 1/4" compressed air line to the locker to refrigerate his lunch!!! No phase change (boiling) necessary. It wasn't very efficient (poor "refrigerator" insulation) and he used lots of compressed air (I calculated thousands of dollars of energy cost per year), but it worked!!!
For a heat only air flow heat pump, why not just remove 1. The Reversing Valve, 2. The Outdoor Expansion Valve, 3. The Outdoor Fan, and just leave the 1. Outdoor Heat Coil, 2. The Compressor, 3. The Indoor Heat Coil, 4. The Indoor Fan, 5. The Indoor Check Valve? Then just recirculate the glycol water solution and let it always stay relatively warm, and then hot on the inside. Wouldn't this be more efficient, and remove half the headache? Also it should work in much colder temperatures! I think it makes more sense with these systems to have one do all heat, and another supply only cold! Then your transfer fluids could be segregated instead of a one size fits all solution. Which doesn't work in a lot of environments! It's pretty cold where I live in the Winter Time, and there are a lot of these Air Source Heat Pumps around that just stop working once it gets down to Freezing Temperatures. So they are spending the money on the Heat Pumps, and also always have to rely on an additional heat source! That has never appealed to me, doesn't make any sense now you are paying for and maintaining two completely different systems all year. Out the window goes your efficiency and your money!
I have a question the inside unit is it supposed to blow the air left and right or just up and down ..because the one I have I have a button that I can press who looks like it blow the air left and right but nothing move inside and there is no difference from the up and down . And to connect to the wifi did someone know how to do that it say reset the unit , I have to press the remote control till I see CF but nothing work.....
If your plan to improve this video, the cursor could be bigger and maybe a brighter Because most of us who are learning, we are not familiar with the name of parts, we can not identify as quickly where the cursor would be.
Sir please make a video on the basis of Outdoor Heat pump AQUANEXA any model of ANX-09, ANX-15, ANX-35, ANX-50, ANX-75 , please sir working of it and how it delivers hot water from ambient temperature along with Heat exchanger , Compressor, 4way valve , fan , condenser fins and it's PCB connect sequence of capacitor of single phase motor and conductor for 3phase motor, please 🙏 sir Which is using R410a refigerant
Please forgive an old fool but I'm having a hard time wrapping my mind around how they heat,isnt freeon supposed to be a cold liquid I cant seem to see how a heatpump ( I have one in my house) is supposed to heat up to create heat. Am I missing something I've watched your video about four times and I just cant have the AAHHHAAA moment( light bulb going off) so please explain it to me in a way that an old man,used to heating with gas,oli and wood heat. I'm sorry I'm just an old dog trying to learn a new trick. Thank you I'm sorry
Yep, heat pumps aren’t that great for the freezing temperatures. They lose efficiency and have to run soooo much to keep the temperature up inside the building. Like you said, nothing beats that blue flame beauty pumping out the BTUs.

Can you make a video about working of heat cool pump used for swimming pool purposes?
This is for an air-source heat pump. Can you show an example of a water-source heat pump or a HP with a geo-source?
So you have heat exchangers instead of an evaporator and a condenser?
Great video. Thanks for the post.

it can be on the 100% saturation line in the psychometric chart. The compressor will push it up into the superheat region
thank you very much!!
Nice animation. However your expansion valve operation is backwards. The valve closest to the evaporator coil (cooling or heating mode) is the one that is engaged while the other is bypassed.
Hye.
What does it mean by cooling mode, heating mode and colling + heating mode?
Cooling mode = provides cooling
Heating mode = provides heating
Cooling + heating = provides heating and cooling simultaneously to different indoor units
Thanks a lot sir
I like your video helpful
We just released some newer, better, videos on heat pumps. Check them out :)
Just wondering..does a heat pump work in the same sense as hot gas defrost?
Love it.
Hmm, so if we put a unit in one room and the other unit in another room, can we heat up one room while cooling down the other?
what if the difference in temperature (indoor and outdoor temp ~1 deg) is too low?
good

Wondering why when the refrigerant leaves the compressor under high pressure, how is it that it is a gas and not a liquid under such pressures.
Because the vapor must cooldown to convert liguid...or loosing his energy and energy is heating..
its a basic law of thermodynamics that heat flows from hot to cold.
