All Electric Bus Air Conditioner

All-electric Bus Air Conditioner Introduction

Guchen Industry is offering a specialized range of all-electrical bus air conditioning system (trolley air conditioner or tram air conditioning) for any type of all-electrical buses, hybrid buses, tramways, and trolleybuses.

The ES series bus air conditioners are roof top mounted all electric bus air conditioning system, designed for 6-18 meter length electrical bus, tram or trolley buses. The hermetic scroll compressor and control system are powered by vehicle electric or battery.
Tips: Customers can choose DC400-720V voltage models according to different demands.


The Main Structure of Rooftop Electric Bus Air Conditioning System

▲ Condenser assembly, evaporator assembly and compressor assembly
▲ DC 500V generator, 380V vehicle alternator
▲ Electronic control box and other major components, such as Dandfoss expansion valve, four ways, Brushless PWM blower and fan with 7 speed air flow adjusting module, intelligent controller Can bus system


ES Series All Electric Bus Air Conditioner Features

◆ Consistently cool, energy efficiency and comfort
Adopting inverter compressor, all-electric bus air conditioning system adjust the cooling speed, offer the best favorable cooling and heating capacity to the people moving, matched to the cooling load inside the passenger compartment according to the indoor temperature changes, with low noise, low energy consumption(adopt R407C environment-friendly refrigerant, volume charge saving more than 20%).

◆ Smart Environment friendly protection
The electric bus a/c adopts efficient air purification system, which is powered by a hybrid drive or all-electric generator or "plug-and-play" depending on your choice to meet the cleaner-operating and more-efficient electric buses. And the electric-bus A/C Parts are subjected to rigorous environment-friendly testing, extend the service life.

◆ Light weight
The 12 m all-electric bus air conditioner’s weight from 400 kg dropped 245 kg, with its body length are controlled within 3 m, directly reduces the weight by more than 40%, lower vehicle weight, improve vehicle safety; More effectively enhance the capacity and mileage of the buses.

◆ Adopts Molded Process Manufacturing
The all-electric bus A/C housing is made of SMC and LFT material, robust structure, greatly reduces the cost.

◆ High-standard Design
Compressors, power-supply module has a waterproof, dust-proof, shockproof, fully meet the automotive parts and components and have reached IP67. 

◆ Safe Voltage Level
More secure system, higher protection degree.

◆ Vehicle Test Verification:
General highway, high ring, a total of 60,000 km comprehensive road, has been tested during the cooling, heating, and other projects.

◆ Through The Rigorous Bench Test
Rated capacity tested (cooling / heating), high-temperature cooling / heating, Defrost, freedom temperature rise, freedom temperature dropping, the frequency-conversion compressor oil level confirmation, the high temperature refrigeration start test, vibration and other tests;

◆ Protection Devices
Over voltage alarm and cut-off function, under voltage alarm and cut-off function, overcurrent protection, compressor discharge temperature protection, high voltage protection of the air conditioning system, low voltage protection A/C system, air conditioning systems temperature control system and other protections


Installation and Project of ES Series Bus Air Conditioner

After the ES series bus air conditioners update and improved the renewed bus ac units more comfort with customers’ demands. Now you can see the below photo, the appearance is look alike SD series, that is because the renewed ac units also has the double return air system, very small in size and light in weight! So it can save more fuel consumption and meet the standard of “new-energy”
