is 134 over 74 blood pressure high
The most likely sign that the evaporator is bad is that the system keeps leaking R-134 and wont hold a charge. The best thing to do is get yourself a recharge kit that has a gauge and check to see what the low side pressure reading is. If its R-134 it should be around 25 to 33 PSI on the low side. Because of the new type of refrigerant R-134 has to run at a much higher pressure then the old R-12 and some components had to be "BEEFED UP" to handle the higher pressure but because of this higher pressure it can sometimes lead to a leak down the road.
134-145 lbs
I am assuming you mean 134/100. This would be considered high blood pressure (hypertension).
The same amount is used as an R12 system.
Are you sure you're connecting to the low pressure line instead of the high pressure line? The low pressure line should have a blue or black dust cap on it, while the high pressure line should have a red dust cap on it.
Look under the hood there are two lines leading to the air conditioner compressor the larger of the two is always the low pressure line this is where you should install 134 freon.
The 1994 Honda Civic air conditioning system has a Freon capacity of five pounds. The 134 Freon refrigerant is no longer sold.
134/78 is close to Prehypertension. While not the reading itself is not always serious, you should look into ways to lower it. Losing weight, exercising, reducing sodium, avoiding smoke and cutting back on caffeine can all help in lowering your blood pressure.
How many pounds of freon does it takes to full the A/C system on a Mack truck CH 613_2004
134 pounds = 60.78 kilograms.
134 / 2.2 = 60.91
