Wondering how Heat pumps work? Look at the video. Not rocket science but very effective and very energy efficient. Visit www.ipoolsupplies.com or http to see what heat pumps are available. Heat your swimming pool for less and use it for a longer period all year round.
I show the basic components that are typical in heat pumps.

love the video really good
ReplyDeleteMuch better description than the "howstuffworks" site which would have completely confused me If I didn't already understand how an A/C system works. Kudos!
ReplyDeleteNew Inverter type Mini-Split heat pumps will keep your home warm down to about 5 degrees F, depending on the model.
ReplyDeleteMy Sanyo Mini-split (also called a Ductless) cools all summer and heats all winter.
Only on really cold days (under 8 deg F or -13C) do we have to turn on some back-up heat.
Paying 21 cents per kWh, & using about 10 kWh per day (during cold weather) is less than 1/4 the cost of heating with oil.
@prostreetcamaro Who wants to swim when it is 30 degrees F or -1 degrees Celsius...
ReplyDeletemuch better use of energy than a fireplace, i know fireplaces are cozy but they also have a low effectiveness and are very bad for people with asthma and other respiratory problems.
ReplyDeletevery well done
ReplyDeleteI have the same picture on my mantle! Different frame though.
ReplyDeletecute video.
ReplyDelete@skittlesmonkey the expansion valve is an isenthalpic expansion, which means that the working fluid maintains its enthalpy energy. if you had a turbine the working fluid would lose its enthalpy
ReplyDelete@skittlesmonkey Well the amount of energy reclaimed from such a turbine would be very small and it is not cost effective to put one in. The expansion valve is much cheaper and there are less moving parts to break or wear so it is also more reliable.
ReplyDeletecouldn't have made it clearer really :)
ReplyDeleteI love this video , oh and I have something to ask you can I send you a message i want to download this album in downloadmusic .im
ReplyDeleteHeat pumps suck if you live in an area that gets under 30 degrees in the winter and that's a fact.
ReplyDeletethanks so much
ReplyDelete@skittlesmonkey the expansion valve is a restriction in the system that enables you to have a high pressure/tempreture side and a low pressure/tempreture side in the system!
ReplyDeleteis there a reason there use an expansion valve instead of something like a little turbine to harness the energy of the moment from high pressure to low, or is it just to make the mechanism simpler?
ReplyDeleteYes!
ReplyDeletethanks for sharing! grazieee
ReplyDeleteAwsome!!!!
ReplyDeleteThanks for posting. This was very helpful.
ReplyDelete@symsterjrs Thanks
ReplyDelete@150MilesPerGallon Thanks for watching.
ReplyDeleteGreat video, Thank you for explaining these systems in great detail :-)
ReplyDeleteexcellent
ReplyDeleteHI DR Z ! RE: INSTALL SENSING BULD . THANKS FOR YOUR RESPONDED DR Z, IT MEAN A LOT TO ME.
ReplyDelete@TheSam201077 he doesnt respond to any messages give up .lol its true ive asked several questions never got an response check with other ppl on youtube .i found some other helpful ppl...
ReplyDelete@TheSam201077 You can replace the fixed orifice with a TXV. The sensing bulb needs to be fastened to the suction line. If the suction line if run horizontal then you need to install it at 4 o'clock on the tubing.
ReplyDeleteHi DR Z ! can I replace a fixed orifice to a txv valve on the fan coil ., also how do you install the remote sensing bold on the suction line . THANK YOU SO MUCH DR. I am a residential installer , just want to learn more .
ReplyDeletecondensing unit?...maybe you mean the outdoor coil.
ReplyDeleteTHANKS DR. I LOVE YOUR VIDEOS AND THE INTELLIGENCE YOU GIVE US ALL TECHS. WITH ALL THE RESPECT YOU MAKE MY DICK GET HARD. I KNOW I'M BEING SORCASTIC UPSS. SORRY BUT I REALLY DO ADMIRE YOU.
ReplyDelete@MrTERRYD55 The accumulator could have accumulated non-condensables throughout the years.
ReplyDelete@DrZarkloff Why do you always replace the accumulator?
ReplyDelete@MrTERRYD55 I'd look for heavy rust. If you find any then you might want to check it for leaks. Also, I always replace the accumulator when I replace the compressor.
ReplyDeleteDr.Z how would you determine if a a
ReplyDeleteccumulator is bad in a heat pump condenser.
Dr.Z how would you determine if a accumulator is bad in a heat pump condenser.
ReplyDelete@quickservicehvac Thanks
ReplyDeletegreat video from Mr.Quick of Quickservice
ReplyDeleteWhat is the correct way to troubleshoot a reversing valve and what is the sequence of operation for two stage a/cs?????
ReplyDelete@Mooseguy15 A heat pump is an air conditioning system that can cool and heat by use of the compressor.
ReplyDeleteIs a heat pump a compressor?
ReplyDelete@thereceman The defrost thermostat stops the defrost cycle when the sensor notices that the condensing coil has a raised temperature.
ReplyDeletedoes the defrost thermostat denergize the compressor when it senses high head pressure?
ReplyDeleteYes. Some commercial heat pumps use solenoid valves instead of a reversing valve.
ReplyDeleteDrZ can we use some alternate solution instead of using reversing can we use also a solenoid valve??
