Explain this image if you even think you understand IR
I was playing with a heat pump Monday and shot this image for fun and got to looking a little closer in the office.
The HP was in operation at the time the image was taken the exterior ambient was about 50 degrees F Notice the compressor temp above 200 degrees the surface temp of the dischage line out of the compressor drops to about 65 F and then the inline dryer temp is 201 F. The discharge line between the compressor and the dryer is roughly 6 inches in length. Explain the temp differential between the compressor and the dryer;-)
May be on to something here…A collecting of hot fluid would be hotter than a stream of it. And painted material might not dissipate heat as quick as unpainted. Does copper dissipate heat quicker than steel?
Jeffrey & all - you can prove / disprove what Charlie is asking by manipulating the emissivity and reflected temperature settings on your own imagers OR you can download Charlie’s image (it is radiometric) and do the experiment with FLIR tools such as any one of these that you can access for free whether you have an imager or not. Of course you will need to do your own research into typical emissivities of the materials…
Ya got it backwards the vapor is hotter than the liquid because it was just compressed by the compressor and has not been turned to a liquid until it reaches its condenser. The fan was operating at the time the image was taken
No change of state its operating in the heat mode it leaves the compressor in a hot vapor and remains in that state until it arrives at the indoor A-coil where it transforms back to a liquid
No liquid in a compressor or at least there is not suppose to be if there is ya have a problem. Compressor take low pressure low temp vapor and creates high pressure high temp vapor that is all they do period
Not going to help ya much think about what I said (the unit was operating in the heat mode at the time the image was taken) that is the main key ya need to fully understand the operation of a heat pump before that image makes much sense IMHO
