As pre-hospital emergency care systems continue to evolve, increasing attention is being paid to the comfort and operational efficiency of the ambulance's medical compartment. Traditional vehicle air conditioning systems rely on the engine; consequently, they often face shutdowns or performance degradation during stationary emergency operations, while noise and exhaust emissions negatively impact both patients and medical personnel. Recently, the adoption and application of DC electric air conditioning technology in ambulances have begun to transform this situation.

In modern emergency medical service systems, the ambulance has evolved from a mere means of transport into a mobile treatment unit. The stability of the interior environment—particularly the reliable control of temperature—is increasingly becoming a critical factor influencing the quality of medical care and patient safety. Corunclima’s specialized air conditioning systems, developed specifically for ambulances, medical vehicles, and rescue units, represent an engineered solution designed to meet this precise need.

As part of Peru's national plan to upgrade emergency medical services, the T35B ambulance air conditioning system—manufactured by Corunclima, a specialized Chinese provider of vehicle-mounted AC solutions—has been successfully installed on a fleet of ambulances procured by the United Nations Office for Project Services (UNOPS). The President of Peru personally attended the delivery ceremony, marking a pivotal step forward in the country's efforts to enhance its public health emergency response capabilities.

In the race against time that characterizes pre-hospital emergency care, an ambulance serves as far more than just a vehicle for patient transport; it functions as a mobile resuscitation unit. The stability of the cabin temperature directly impacts both the patient's vital signs and the medical staff's ability to maintain focus during critical procedures. In recent years—driven by the deep integration of "green healthcare" principles and new energy technologies—a DC electric air conditioning system capable of operating independently without relying on the vehicle's main engine has been rapidly gaining traction, bringing about a revolutionary transformation in emergency medical services.

Within the emergency medical system, an ambulance serves as far more than just a means of transport; it functions as a mobile resuscitation unit. The environmental quality inside the medical cabin directly impacts a patient's physiological and psychological state, while also influencing the operational efficiency of the medical crew. In recent years, DC electric air conditioning systems have seen accelerated adoption within the ambulance sector. By fundamentally resolving the inherent drawbacks of traditional systems—such as excessive noise, strong vibrations, and a reliance on engine idling—these new systems represent a qualitative leap forward in pre-hospital emergency care.

​As my country's emergency medical system continues to raise its standards for patient transport comfort and safety, the ambulance—often dubbed a "mobile ICU"—is seeing the precise regulation of its internal environment emerge as a new focal point for technological innovation within the industry. Recently, a series of DC electric air conditioning products—developed specifically for new-energy ambulances and other specialized vehicles—have been successively introduced to the market. These innovations aim to resolve critical industry challenges, such as poor cooling performance and excessive energy consumption while the vehicle is parked during emergency operations, thereby providing a more stable and cool environment to safeguard the vital lifeline of emergency rescue.

As the global healthcare system accelerates its green and low-carbon transformation, electric ambulances are gradually becoming the new mainstay of urban emergency response. However, amidst this electrification wave, a critical technical challenge concerning patient safety and emergency care quality is becoming increasingly prominent—how to provide stable, powerful, and quiet cooling for the ambulance cabin while parked or traveling at low speeds?
