Iran Intercity Bus Air Conditioner is crucial for intercity buses in Iran, which are the most popular way to travel between cities due to their affordability and availability.
There are two main types of buses in Iran:
Standard Buses – Basic and budget-friendly, but less comfortable for long trips.
VIP Buses – More spacious, with reclining seats and better amenities, ideal for long journeys.
Restroom Availability on Iran Buses
Iranian buses do not have onboard toilets. However, drivers stop at service areas with restrooms, food stalls, and shops every few hours.
If your Iran Intercity Bus Air Conditioner fails to start, follow these steps to troubleshoot and resolve the issue:
Check the alternator and voltage:
If the alternator belt is broken or the voltage regulator is faulty, insufficient power will be supplied to the air conditioner. Use a multimeter to check the output voltage (typically around 28V) and replace the alternator or belt if necessary.
Battery Voltage:
When the voltage falls below 22V, the air conditioner will automatically shut down for protection. You will need to jumpstart the battery or activate the backup battery pack.
Control Panel and Switch Failure
Button or Panel Malfunction:
Clean the contacts or replace a damaged switch. If the control panel is unresponsive, check the wiring or replace the panel.
Mode Setting Error: Verify that the air conditioner mode (Cooling/Heating) is selected correctly.
Compressor and Refrigeration System
Compressor Failure: If the compressor does not operate, it may be due to a damaged electromagnetic clutch, refrigerant leak, or overcurrent protection. Check the pressure sensor (such as an ER04 failure) or replace the compressor.
Refrigerant Problem: Abnormal pressure or leakage will cause a protective shutdown. Refrigerant must be added and the leak repaired.
Other Common Causes
Poor Cooling: Clean the roof fins and check if the fan is operating properly.
Sensor Failure: If the temperature sensor is abnormal (codes E11-E19), the faulty component must be replaced.
Emergency Measures
Temporary Cooling: Open windows for ventilation, use sunshades, and use fans to assist with cooling.
Professional Repair: If self-diagnosis fails, contact a professional to repair the circuit or compressor.
Tehran Buses: Affordable City Transport
Tehran has two types of buses: regular city buses and the Bus Rapid Transit (BRT) system. Regular city buses operate on standard routes and are mostly used for short distances. They are often not air-conditioned. The BRT system, on the other hand, runs on dedicated lanes, making it is a faster and more reliable option, especially for long distances and high-traffic areas. With extensive routes covering most parts of the city, buses are a popular and affordable way to get around Tehran. You can pay the fare using a Tehran public transport card, making the process easy and cash-free.
