As anti-idling regulations continue to tighten across North America, demand for high-performance electric APU systems is rapidly increasing in the heavy-duty trucking industry. Fleet operators and owner-drivers are now looking for solutions that can deliver stronger cooling performance, lower fuel consumption, and quieter overnight comfort without relying on engine idling. According to Corunclima, large cooling capacity electric APU systems are becoming one of the fastest-growing segments in the truck parking air conditioner market. The company’s latest electric APU solutions are designed specifically for long-haul trucks operating in high-temperature regions across the United States and Mexico.

Driven by the "Dual Carbon" goals, my country's new energy commercial vehicle sector has developed rapidly, and electric trucks are no longer a novelty. However, a long-overlooked niche—electrified refrigeration equipment for trucks—is quietly emerging as a new industry hotspot. As demand for cold chain logistics continues to grow and environmental regulations become increasingly stringent, traditional fuel-driven refrigeration units are being rapidly replaced by electric alternatives; a technological revolution centered on the "Green Cold Chain" is now well underway.

The global cold chain transportation sector is experiencing rapid expansion as demand rises for frozen food, pharmaceuticals, seafood, dairy products, and temperature-sensitive goods. In this fast-growing market, the “truck freezer cooling unit” has become one of the most important technologies supporting modern refrigerated logistics. Industry analysts note that reliable transport refrigeration systems are now essential for maintaining product quality during long-distance delivery. From urban food distribution to cross-border pharmaceutical transportation, truck freezer cooling units are helping logistics companies maintain stable temperatures while reducing operating costs. Among the manufacturers gaining attention in this sector is Corunclim, which offers a wide range of engine-driven transport refrigeration units for light trucks, medium-duty trucks, and large refrigerated vehicles. According to product information released by the company, the systems are designed to support frozen and chilled transportation with temperature ranges reaching as low as -18°C.

As new energy technologies continue to permeate the field and public health emergency systems are steadily upgraded, DC electric air conditioners for ambulances are moving from an “optional feature” to a “standard component.” Traditional ambulance air conditioners rely largely on the vehicle’s engine, which not only consumes high amounts of fuel and generates significant noise but also fails to provide continuous cooling when the engine is turned off while parked. DC electric air conditioners, by contrast, draw power directly from the vehicle’s battery or high-voltage traction battery and operate independently of the engine, becoming an essential technological safeguard in pre‑hospital emergency care.

A defining advantage of electric van air conditioning is its ability to operate without engine idling. This eliminates unnecessary fuel consumption and reduces wear on the engine, which is a major cost factor for fleet operators. In traditional systems, air conditioning requires the engine to run continuously, especially in hot climates or during loading and unloading operations. In contrast, electric systems are designed for zero-idle cooling, allowing drivers and passengers to maintain comfort without compromising vehicle efficiency.

Against the backdrop of deepening carbon reduction goals, the cold chain logistics industry is undergoing a power revolution centered on electrification. As a key component of refrigerated transport, all-electric truck refrigeration units are gradually replacing traditional diesel-driven systems, becoming the standard choice for new-energy refrigerated trucks. For a long time, conventional refrigerated trucks have relied on independent diesel engines to power the refrigeration unit, which not only consume large amounts of fuel and incur high maintenance costs, but also face increasingly stringent emission restrictions and road-access limitations in urban delivery scenarios. In contrast, all-electric refrigeration units draw power directly from the truck’s traction battery, completely eliminating the need for a diesel auxiliary engine and achieving zero tailpipe emissions during both driving and refrigeration. This makes refrigerated trucks far more environmentally friendly when operating in sensitive areas such as city centers and hospital districts, while also granting operators more favorable road-access rights.

The global commercial truck refrigeration industry is entering a new phase of technological transformation as logistics companies, food distributors, and pharmaceutical transport operators seek more efficient and environmentally friendly cold-chain solutions. Driven by rising demand for temperature-sensitive transportation, manufacturers are introducing advanced refrigeration systems that improve cooling performance while reducing fuel consumption and emissions. Among the companies expanding their presence in the sector is Corunclima, a manufacturer specializing in transport refrigeration units and vehicle climate-control systems. The company has developed a broad portfolio of refrigeration solutions for refrigerated trucks, vans, trailers, and electric commercial vehicles. According to company information, Corunclima has more than two decades of experience in mobile temperature-control technology and serves customers in over 50 countries.

​In recent years, driven by the national “dual carbon” strategy and the full implementation of the 14th Five-Year Plan for Cold Chain Logistics Development, the green transformation of the cold chain logistics industry has significantly accelerated. Since the beginning of this year, under the combined influence of favorable policies and robust market demand, electric refrigeration units for vans have moved from the “concept exploration” stage to “large-scale application” at an unprecedented pace, becoming a key enabler for quality upgrades in the cold chain transport sector.

Among the leading innovations in this sector, modern van refrigeration systems are designed to provide stable cooling performance even under extreme environmental conditions. Advanced refrigeration units can maintain temperatures ranging from chilled conditions at -5°C to deep freezing temperatures as low as -20°C. These systems are widely used for transporting dairy products, seafood, frozen food, vegetables, beverages, flowers, and medical supplies.
