As the penetration rate of new energy buses continues to increase, public transport operators worldwide are reducing emissions and lowering total lifecycle operating costs, making every component of bus HVAC systems crucial. Energieeffizienz, intelligent control, Zuverlässigkeit, and ease of maintenance are becoming key indicators in the purchasing decisions of global bus manufacturers, public transport operators, and fleets. Letztes Jahr, the TKT Group obtained a new patent for an advanced protective cover structure specifically designed for bus HVAC systems. This patented technology surpasses the standards of the bus air conditioning industry in three dimensions: Energieeffizienz, passenger comfort, and environmental performance.
Core of the Patent
Highly Efficient Synergy: Evaporative Emission Unit and Intelligent Control Unit
The core of this patent lies in the ingenious adjacent configuration of the evaporative emission unit assembly and the intelligent control unit assembly. Zusammen, they create a new and more efficient air conditioning operating mode.
Speziell, the evaporative emission unit is equipped with a first air outlet and a second air outlet on each side, while the raised end in the middle of the assembly houses a high-efficiency evaporator fan. This structural design not only optimizes airflow within the bus but also results in a more uniform temperature distribution, reducing discomfort caused by localized temperature differences. Gleichzeitig, the new protective cover design comprehensively optimizes dustproofing, waterproofing, airflow guidance, and noise reduction, effectively protecting core electrical components. This extends the lifespan of the evaporator fan and control unit, while also enhancing the passenger experience.
On-Demand Adjustment: Improved Energy Efficiency
The new design allows for more flexible application of the control unit assembly. The system can adjust the air conditioning operating mode on demand based on the temperature, Feuchtigkeit, and fresh air requirements inside and outside the bus, effectively reducing unnecessary energy consumption.
Speziell, when external environmental conditions are suitable, the system can automatically introduce outdoor air. This change reduces the workload of the compressor, thereby improving the system's energy efficiency ratio (EER/COP). For bus and long-distance passenger transport companies, this means lower energy consumption per 100 kilometers and longer driving range. For vehicle manufacturers, it means better system integration efficiency and higher product competitiveness.
Umweltfreundlich
The design also fully considers environmental protection requirements. By reducing the compressor's high-load operating time, the overall carbon emissions of the system are further reduced. This aligns with the current global trend in the bus air conditioning system industry towards low-carbon, green, and intelligent development.
Zusammenfassend, the new patent creates a more comfortable riding environment for passengers while also balancing the energy efficiency and maintenance costs of the air conditioning system.
How Bus HVAC Systems Work – Working Principles
A typical bus air conditioning system performs three core functions in the passenger compartment: Kühlung, Entfeuchtung, and air filtration. Its cooling cycle relies on the coordinated operation of the following key components:
1. Kompressor für Busklimaanlagen:
The core component of the bus air conditioning system, responsible for circulating the refrigerant under high pressure and serving as the power source for the cycle. Electric buses use variable frequency electric compressors, enabling precise load matching. Traditional diesel buses typically use engine-driven or independently driven compressors.
2. Kondensator:
High-temperature, high-pressure gaseous refrigerant flows into the condenser coils. The condenser fan uses outside air to blow across the coils, rapidly dissipating heat into the air, causing the refrigerant to condense into a liquid state.
3. Dryer Filter and Expansion Valve:
The liquid refrigerant passes through the dryer filter to remove moisture and impurities. It then passes through the expansion valve to reduce pressure before entering the evaporator. If moisture and impurities are not removed, ice blockage, dirt blockage, and acid corrosion will occur. Over time, the system will be unable to operate stably and efficiently.
4. Verdampfer:
Low-pressure liquid refrigerant enters the evaporator coils and absorbs heat to evaporate. It absorbs heat from the air inside the bus. The refrigerant carries away the heat, causing a significant drop in air temperature. As the air temperature decreases, its capacity to hold water vapor reduces, causing excess water vapor to condense into small droplets that adhere to the evaporator surface. This condensate flows down the evaporator fins to a drip tray below, and then through a drain pipe to the outside of the vehicle.
5. Thermostat and Control Unit:
The thermostat sensitively captures temperature data inside the bus and sends a signal when cooling is needed. The intelligent control unit then precisely manages the entire cycle based on the feedback data.
Bus HVAC Systems Types
1. Auxiliary Engine Driven Type: An independent auxiliary engine drives the compressor, suitable for medium- and long-distance tour buses.
2. Main Engine Driven Type: Driven by a belt-connected crankshaft, commonly found in city buses and minibuses.
3. Electric-Driven Type: Powered by the vehicle's battery, standard configuration for pure electric and hydrogen fuel cell buses.
TKT's new patented design is compatible with multiple product types mentioned above. Inquiries are welcome.
Covering All Vehicle Types: From City Buses to Electric Buses
While the overall requirements for bus climate solutions are similar across different vehicle types, there are still some unique needs. TKT, as an experienced manufacturer of bus HVAC systems, offers a comprehensive product range to meet various scenarios.
1. City Buses AC: Frequent door opening and closing, high passenger turnover, usw., require systems that can quickly cool and restore the bus's interior temperature while maximizing energy efficiency and uptime.
2. Tour and Long-Distance Buses AC: Long-distance travel requires stable cooling, Niedriges Geräusch, and reliable performance over thousands of hours of operation.
3. School Buses AC: Passenger safety is paramount. A flat roof provides better protection for school buses. Health and safety are also a top priority.
4. Electric Buses AC: Zero-emission powertrains present challenges in battery thermal management. Bus HVAC systems must be extremely efficient to extend battery range. New electric buses typically employ integrated air conditioning andThermalmanagementsysteme der Batterie (BTMS)to ensure that the battery cells and passenger areas are within optimal temperature ranges.
