​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?
