If the pressure it too high, the car will run lean. 4 psig (20°F from P/T chart) – As refrigerant boils, more of the liquid vaporizes – More liquid present in the coil increases its efficiency. 1 Feet) Red Hose: high pressure; Blue Hose: low pressure; Yellow Hose: refrigerant (800 PSI working pressure and 4000 PSI burst pressure ) 1 x Corkscrew 1 x Dual-purpose Valve Wrench. Number of low side refrigerant ports available. This means that the inlet pres-sure must be at least 10 psi higher than the outlet pressure to allow for proper water flow through the water The chart below reflects the factory dip-switch settings for R-404A models using the "E" board. Environmentally acceptable replacement compounds are therefore needed for use in existing medium and low temperature. External equalizer location 9. Other pressure-related issues could arise for some automotive A/C R-134a systems, including operation of condenser fans and any other high-pressure-side controls if used. (Use mounted thermometer. if the pressure on either the high or the low side rises above 0 psi, restart the recovery process. a/c hasn't been used in 8 years but everything was still functioning.

According to the ASHRAE classification for refrigerants, the classification for the least toxic c. Low pressure side Suction from the compressor pulls the high pressure/temperature liquid R134a through small variable orifice of the TX valve and into the low-pressure side of the A/C system. Since the pressure will run lower on the low side, you want to drop the low side pressure switch down to 18-20psi or so. 1 96" red R-12 hose c/w ball valve. 13201-000010 Recommended for use with Unicla A Group compressors 45 – 170cc.

If it cannot be identified by the cap color, it can be identified by tracing the low pressure line that connects the evaporator to the compressor. Allow R134A to vent until all pressure is gone from high and low sides. Determine the relative humidity and air temperature. The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used. It is capable of handling a maximum pressure of 800 psi, and it weighs 7. If your ports are located in the compressor, the low side is marked by an "S" and the high side by an "H". 4-60” (3/8” VAC) 1/4” & 3/8” SAE. For high/low pressure and refrigerant.

Beyond that, there are also other key parameters that need to be considered to evaluate the. Part 2 of 2. The molecule size of R134a is smaller than that of R12, so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used. That is what the pressure is telling you, not the amount of refrigerant in a system. Primarily there are two components of the R 134a pressure temperature chart: one is temperature and the other is pressure. Same as: 0647-0287-10 10a. Refrigerant Management System: Displays refrigerant use and monitors remaining filter life. There is a common chart called a P&T chart which will help guide you to finding an acceptable high side pressure related to the outside temperature, and naturally you want to look at the vent temperatures the low side pressure. 50” x 5” x 1 Drier: The primary function of the drier is to separate gas and liquid. Air in system - indicated by excessive head pressure and possibly bubbles in sight glass. i found the leak, it was the valve on the high side.

With the A/C turned OFF - On a cold day the pressure will be low, on a hot day the pressure will be high. Air too cold d. At last, the low pressure and temperature R134a passes through the evaporator (stage 5 in Figure 1) to absorb the heat from the air by the means of absorbing heat of vaporization (process 4 to 1 in Figure 2). This can cause Extremely high head pressure. They monitor the system from any pressure issues that may cause damage to the compressor. The recommended pressure for a home refrigerator using R134A refrigerant is between 2 psig and 150 psig. Overview Summary Charging hose, gauge and Low Side manifold kit for Mini Split System Installations. Evaporator oil logged 6. The compressor will take refrigerant from the low-pressure side and compress it, pushing it into the high-pressure side, which also makes it heat up. I haven't tapped the high side and won't unless adding refrigerant doesn't fix the problem. In general, vehicle a/c system pressures fall within a certain range; low side between 22psi to 66psi, high side between 86psi to 292psi. Prompts appear when 1/3 of filter life remains. Go to step # 4 in Charging an A/C System that is low on Refrigerant (below) CHARGING AN A/C SYSTEM THAT IS LOW: Make certain that the dispensing valve on the refrigerant source is closed. If you know the pressure of refrigerant, you know its corresponding temperature simply by looking at the pressure/temperature chart for that refrigerant. Long or small line d. As a hot low-pressure gas, the refrigerant moves to the compressor where the entire cycle is repeated. 5 14002951 R134a 18 Acura SLX 1998 1999 All Eng PAG46 5 14002951 R134a 21 Acura SLX 1996 1997 All Eng PAG46 5 14002951 R134a 28. 5% recovery efficiency for standard and hybrid vehicles and fully automatic function. 7 kPa) high-side pressure and 24-31 psi (165.
