Position started from 134 a 2 over 2 3 4. F they started using to make up that 10%. efficiency they started using this. internal heat exchanger and it improves. the efficiency of the typical. airconditioning system by about 10% and. so if you look here you know you. recognize here this is where it bolts on. to the firewall this is my suction line. coming back from the THD valve back to. the compressor and here's the liquid. line coming up from the condenser to the. THD Belen and the way this works do you. see on the two lines are molded together. here and here it's just a double wall. pipe it's pipe within a pipe and so. you've got the inner pipe here and then. the outer pipe here these are just. little spacers and keep the two pipes to. keep the inner pipe centered in the. outer pipe and so the liquid the liquid.

Comes in here and it comes up so that. the space is here the liquid comes up. the outside of the tube right and the. closed the suction refrigerant returning. from the evaporator goes down the center. section of the tube so if I miss the. temperature of the typical liquid. refrigerant coming out of the condenser. it's usually maybe 120 130 degrees we're. in a hot summer day if I put my hand on. the suction line come down the firewall. or temperature would be expected to be a. cold follow these 50 degrees probably on. a technicality so what we're doing here. were you so the refrigerant coming out. of the evaporator is dumb. it's spent it's been used up evaporating. in the environment but it is still cold. so I'm using the cold such a refrigerant. going down the center here by pumping. the hot liquid refrigerant around the.

outside of that total pipe. I used the code returning refrigerant in. the suction line to expect a few more. degrees the temperature out of the. liquid refrigerant before it gets to the. gets over to the evaporator of the tnz. back. so in improve. the efficiency of recovers reduce the. temperature of the refrigerant
