SUCTION HOSE
The suction hose from the evaporator outlet to the compressor suction port is insulated and the hose size is increased.
EVAPORATOR CAPACITY
The evaporator incorporates “rifled” coil tubes. The rifling process adds small grooves to the interior wall of the tubes. The “rifling” increases the internal surface area and turbulence inside the evaporator. The new evaporator increases the coefficient of heat transfer as the air passes across the evaporator.

TEMPERATURE TESTING - TOOLS
29
For a/c temperature testing, an infrared thermometer is not typically recommended. They are easy to use, and can provide rough measurements, but when trying to diagnosis an a/c system problem, they most often do not provide reliable data.
It is normally recommended to use a digital thermometer with touch probe for a/c temperature testing.

TEMPERATURE TESTING – P/T Chart
31
Saturation Properties (P/T) Chart for R12, R134a and HYF1234 can be invaluable when diagnosing an a/c problem. If you know the temperature/pressure, the user can quickly determine the corresponding value for the refrigerant type. For example one question that is commonly asked by service technicians is, what should the high side pressure be. The following two ways can be used as a quick guide or rough estimate to determine high side pressure.
1) Ambient temperature (x) 2 or (x) 2.5 = high side psi• Example: 95°F (x) 2 = 190 psi and/or 95°F (x) 2.5 = 237 psi
2) Ambient temperature + 40 = Saturation temperature
• Example: 95°F + 40 = 135°F
Consult the P/T Chart at the right and find 135°F under the R134a column to find the high side pressure range, 215-217 psi
See the Appendix (4.1, 4.2, 4.3, 4.4 and 4.5) at the end for full size printable P/T chart

• The receiver-drier is used in conjunction with a thermal expansion valve (TXV).
• Little to no temperature differential between inlet and outlet
• Restriction at the inlet to the drier will cause high side head pressure.
• Restriction at the outlet tube will be indicated by low head pressure and little to no cooling.
NOTE: Typically the drier is located in the coolest area away from heat sources, but when this is not possible, consider insulating the drier. Overheating the drier can result in the release of moisture from the desiccant that will freeze at the TXV orifice.

The suction accumulator is similar to a receiver-drier but serves a different function.
• The accumulator is used in conjunction with a fixed-orifice tube (FOT).
• The accumulator is larger than a receiver-drier in size/volume.
• The accumulator is typically at or near the evaporator outlet.
• The accumulator stores excess liquid to prevent liquid refrigerant from reaching the compressor and causing damage to the compressor.
• The accumulator assures that the compressor only receives vapor.
• The inlet and outlet temperature is about the same.

TEMPERATURE TESTING – EVAPORATOR
37
The evaporator like the condenser consist of a refrigerant coil mounted in a series of thin cooling fins. It provides a maximum amount of heat transfer in a minimum amount of space.
The evaporator receives refrigerant from the “TXV” or “FOT” valve as low pressure, cold atomized liquid. As this cold refrigerant passes through the evaporator, heat moves from warm air to the cooler refrigerant.
When the liquid refrigerant receives enough heat to induce a change of state, a large quantity of heat moves from the air to the refrigerant. This causes the refrigerant to change from a low pressure, cold, atomized liquid, into a low-pressure, cold vapor. The vaporous (saturated) refrigerant then continues onto the inlet (suction) side of the compressor. Evaporator Air Temp

Vent Outlet °F
Delta∆ °F
1. Maximum fresh air
2. Measure and record the inlet air temperature before the evaporator
3. Measure and record the air temperature after the evaporator
4. Record the temperature drop across the evaporator. The Delta∆ is dependent on system design and requirement.

TEMPERATURE TESTING – FOT
38
The fixed orifice tube (FOT) is used in conjunction with a suction accumulator. The FOT is located in the liquid line between the condenser outlet and the evaporator inlet, and is designed to meter refrigerant into the evaporator.
The most common type FOT contains no moving parts and is available with different orifice sizes depending on application. The FOT separates the high/low side of system and the control of refrigerant flow is accomplished by turning the compressor on and off.

TROUBLESHOOTING - TXV
39
The thermostatic expansion valve (TXV) is non-adjustable and is located at the inlet of the evaporator and separates the high and low side of the system.
The refrigerant flow to the evaporator must be controlled to obtain maximum cooling, while assuring complete evaporation of the liquid refrigerant within the evaporator.
The TXV “H” block design performs the following three functions.
• Metering Action, 9, changes the pressure of the incoming liquid refrigerant from high pressure, 3, to low pressure, 5.
•Modulating Action, 1 & 7, fluctuates towards the open or closed position to control the liquid refrigerant passing through the orifice, 9, at the ball valve, 4.
• Controlling Action, 1 & 8, as increase heat is sensed, 1, the valve, 8, moves toward an open position to increase refrigerant flow. An increase in compressor speed or a decreased in heat load will cause the valve to move toward a closed position.

TROUBLESHOOTING - TXV
40
If the TXV is easily accessible use the following test to troubleshoot.
1. A/C compressor disengaged.
2. Apply heat for a few minutes to the TXV power element using hot air or a hot rag depending on what is readily available. This will cause the valve to fluctuate open.
3. Engage the compressor and continue to heat the power element. Record the low and high side operating pressures.
4. Cool the power element by placing a small bag of crushed ice or ice pack on the power element, and observe the low side pressure.
5. The pressure values for the two test in steps 2 and 4 must be different. If the values do not change, suspect a faulty TXV.
Example: In step 2 when heat is applied to the power element, the low side pressure increased to about 20 psi, and then in Step 3, when ice is placed on top of the power element, the low side pressure quickly decreased to about 10 psi.

TROUBLESHOOTING - TXV
41
If the TXV is not easily accessible ;
The TXV is not always easily accessible on heavy-duty off highway vehicles. A technician can sometimes spend from a couple hours to several hours replacing a TXV. The following can be used as a quick way to help indicate if the TXV is working.
1. Connect manifold gauge set.
2. Ambient air temperature is above 80°F and the recirculation is set for maximum fresh air
3. Operate the system with the blower fan on high for about 5 minutes. Observe that the low side pressure increases.
4. Turn the blower fan to the low speed position and observe the low-side gauge reading. The pressure should drop 2-3 psi almost immediately. When the blower is on low speed, less air flow is moving across the evaporator and the TXV will immediately begin to fluctuate (close) restricting refrigerant into the evaporator.
5. Turn the blower fan back to the high position and observe the low-side gauge, it should rise 2-3 psi almost immediately. When the blower fan is on high, more air flow is moving across the evaporator and the TXV will immediately begin to fluctuate (open) allowing more refrigerant to enter the evaporator.
6. If the low-side gauge reading can be influenced with the blower fan speed, this indicates that the TXV is modulating.

A couple of the not so normal A/C calls
Technical Help Desk
© 2014 AGCO Corporation
From the File – Poor Cooling & Low Pressures
44
Complaint: Poor cooling and the pressures are low
Work Performed: Before contacting the help desk, the service technician replaced the compressor, the receiver-drier and the TXV, but without making any difference to the cooling performance or the pressures. The technician planned to replace the condenser next, but decided to first make a phone call.
Pressure: The technician reported 125 psi high side and 2 psi low side, and also reported that the pressures look almost normal when charging the system. The age of the vehicle is about 12 years old.
Help Desk: Advised to check for a hose restriction. 1. Perform a visual inspection. 2. Measure the temperature at each end of the hoses to isolate.
Feedback: The service technician performed the visual inspection, but due to the age of the vehicle, made the decision to replace the hoses. Reported back that the issue was resolved after replacing the hoses.

From the File – Cannot Charge the System
45
Complaint: Unable to fully charge the system
Work Performed: Before contacting the help desk, the service technician installed a new compressor, replaced the receiver-drier, TXV, and flush the condenser for oil removal. But now, the system will only take about 1/3 of the recommended refrigerant charge and then stops.
Pressure: The technician reported that the high side and low side have the same pressure reading of 125 psi at 1000 engine rpm.
Help Desk: Advised that most likely the new compressor has been slugged with liquid and broke the suction valve.
Feedback: Installed another compressor. Evacuated the system below 1000 micron and then carefully recharged the system without any problem.
