The parking AC evaporator is designed to deliver reliable and comfortable climate control across a wide range of applications.
At its core is a compact and well-engineered heat exchange unit measuring 168 mm in length, 76.2 mm in width, and 500 mm in height, with mold dimensions of 7 × 251 × 12.7.
This optimized size allows easy integration into auxiliary air-conditioning systems while maintaining strong thermal performance.
The system features hydrophilic corrugated sheets with a fin spacing of 1.9 mm and a fin thickness of 0.115 mm.
This fin design increases the effective heat transfer area, improves moisture drainage, and supports stable operation with reduced airflow resistance.
As a result, the system operates quietly while maintaining high efficiency, creating a more comfortable user experience.
Constructed entirely from aluminum, including durable 1.5 mm aluminum sheet metal, the system offers a lightweight yet robust structure with excellent corrosion resistance and long service life.
A buyer compares two quotes for the same duty: a 9 kW direct-expansion evaporator for a rooftop unit. One supplier ships in 21 days, the other in 45. The price gap is 34 percent. Both drawings show the same face area, the same fin spacing, and the same tube diameter. The difference hides in three l...
READ MOREA maintenance technician stops in front of a rooftop unit that is blowing warm air on a hot afternoon. The filter is clean, the thermostat is correctly set, and both fans are running. The problem is almost certainly inside the sealed refrigerant loop. That loop, repeated in nearly every air conditi...
READ MOREWhen a chiller leaves the factory, its efficiency, reliability and operating cost have already been determined by a small set of design choices. The most consequential of those choices sit inside the refrigerant circuit: the evaporator, where heat is absorbed from the building water loop, and the c...
READ MOREA Parking AC Evaporator operates under conditions that differ significantly from conventional vehicle air conditioning systems. Since the engine is often turned off during parking, the evaporator must deliver rapid and stable cooling while minimizing power consumption. Uniform refrigerant distribution across every flow channel ensures that the available cooling capacity is fully utilized, preventing localized frost formation and maintaining consistent cabin temperature throughout long parking periods.
Engineers carefully optimize internal tube structures and refrigerant pathways to reduce pressure loss and improve evaporation efficiency. These design improvements help battery-powered or auxiliary air conditioning systems operate longer while consuming less energy, making them particularly valuable for commercial trucks, recreational vehicles, and long-distance transportation fleets.
Weight reduction and manufacturing efficiency have become important considerations for modern parking air conditioning equipment. High-performance aluminum tube technology offers an effective balance between thermal performance, structural strength, and lightweight construction. Compared with conventional copper solutions, aluminum enables higher production efficiency while reducing raw material consumption and supporting automated manufacturing.
Hangzhou Yijie Refrigeration Technology Co., Ltd. has accumulated 12 years of expertise in heat exchanger development and possesses multiple core technologies. By replacing traditional copper materials with advanced aluminum tube technology, the company reduces material costs by more than 30% while providing significant advantages for mass production. This technological innovation allows manufacturers to improve product competitiveness without sacrificing cooling performance or reliability.
Parking air conditioning systems frequently experience repeated startup cycles, continuous vibration, varying ambient temperatures, and prolonged exposure to outdoor environments. These operating conditions place high demands on evaporator durability. Reliable products must maintain structural integrity and heat exchange efficiency throughout years of continuous service without developing refrigerant leakage or corrosion-related failures.
| Performance Verification | Practical Benefit |
| 500-hour standard salt spray test | Outstanding corrosion resistance in outdoor operating conditions |
| 50,000 pressure cycle verification | Reliable operation under repeated refrigerant pressure fluctuations |
| High compressive strength | Reduced leakage risk and longer service life |
Hangzhou Yijie Refrigeration Technology Co., Ltd. validates every heat exchanger through 500-hour standard salt spray testing and 50,000 pressure cycle verification. Both corrosion resistance and compressive strength exceed national standards, ensuring dependable operation for demanding parking air conditioning applications.
Parking air conditioning systems vary greatly depending on vehicle type, battery capacity, compressor configuration, installation space, and cooling demand. A customized evaporator allows manufacturers to optimize tube arrangement, fin density, airflow direction, and connection locations according to specific project requirements. This approach improves thermal efficiency while simplifying installation and reducing unnecessary energy consumption.
Customized engineering also enables better integration with electric compressors and auxiliary cooling systems, helping parking air conditioners maintain stable cabin temperatures while extending operating time under limited power availability.
Many innovations used in parking air conditioning systems originate from broader heat exchanger applications. Experience gained from household air conditioners, automotive air conditioners, dehumidifiers, cold chain systems, eco-friendly equipment, machine rooms, and warehouse cooling provides valuable engineering knowledge in airflow optimization, corrosion protection, structural durability, and efficient thermal management.
With strong customization capabilities, Hangzhou Yijie Refrigeration Technology Co., Ltd. develops heat exchangers for household AC, automotive AC, dehumidifiers, cold chain systems, eco-friendly equipment, machine rooms, and warehouses. Supported by more than 12 years of engineering expertise, advanced aluminum tube technology, and rigorous durability testing, the company delivers reliable Parking AC Evaporator solutions that combine lightweight construction, efficient manufacturing, excellent corrosion resistance, and long-term operational stability for modern vehicle climate control systems.
