Abstract: In order to effectively alleviate the shortage of medical resources caused by public health emergencies, the purpose of quickly solving the problem of admission of mild patients has been achieved. This paper introduces a vehicle-mounted negative pressure medical shelter, which can meet the limitations of medical shelter in terms of mobility, rapid maintenance and emergency. Through the three-dimensional mathematical model construction, overall scheme design, working principle, shelter structure and functional design of each system, the air volume, refrigeration, heating capacity and light intensity are verified by calculation, and the results show that the performance meets the design requirements and meets the customer's use requirements.
