Toyota Landcruiser HDJ100 AC Evaporator Replacement
Recently we replaced the Air Conditioning Evaporator on a Toyota Landcruiser HDJ100.
This Toyota Landcruiser HDJ100 was booked in for a mobile regas service with us. The owner had complained that the air conditioning wasn’t cooling enough. After pressure testing the system and inspecting for leaks, we discovered the evaporator was leaking.
Once we replaced the Toyota Landcruiser HDJ100 AC Evaporator and completed the air conditioning service which includes a deep vacuum to remove spent gases and moisture. A vacuum leak test follows this before regassing. We then regas the Toyota Landcruiser HDJ100 air conditioner to the manufacture specifications.
Oil is top up and UltraViolet dye installed. Finally, the air conditioning system is comprehensively re-tested to check the overall performance. Now the Toyota Landcruiser has icy cold air conditioning once again.
The vehicle air conditioning Evaporator Like the condenser, the evaporator is also a heat exchanger consisting of tubes and fins. However, that’s where the similarity ends. Unlike a condenser, which is designed to release large quantities of heat, an evaporator is used to absorb large amounts of heat. An evaporator is also much smaller than a condenser and is part of the system’s low side. Evaporators located in the air handling case along with the blower.
Its primary duty is to remove heat from the inside of your vehicle. Also, the secondary benefit is dehumidification. So as warmer air travels through the aluminium fins of the cooler evaporator coil. The moisture contained in the air condenses on its surface. Also, dust and pollen are passing through stick to its wet surfaces and drain off to the outside. On humid days you may have seen this as water dripping from the bottom of your vehicle. Rest assured this is perfectly normal.
The ideal temperature of the evaporator is 0° Celsius. Refrigerant enters the bottom of the evaporator as a low-pressure liquid. The warm air passing through the evaporator fins causes the refrigerant to boil (refrigerants have a low boiling point). As the refrigerant begins to boil, it can absorb large amounts of heat. The heat is carried off with the refrigerant to the outside of the vehicle.
Your car air conditioning system is made up of many working parts like:
• Receiver Drier
• Expansion Valve
• Cabin Filter
KEEPIN’ COOL CAN SUPPLY A RANGE OF AUTO AIR-CON EVAPORATORS TO SUIT BOTH NEW AND OLD VEHICLES.
