Basic situation of customers:

Imaging department development requirements for regional healthcare benchmarks Danzhou People's Hospital in Hainan, serving as the medical hub for western Hainan Province, shoulders the responsibility of providing healthcare services to over two million residents in Danzhou and surrounding areas. Its Department of Medical Imaging, a core facility within the hospital, is equipped with advanced imaging apparatus and equipment including CT, MRI, and DSA systems. The department conducts over 300 examinations daily, serving more than 100,000 patients annually. Besides clinical diagnostics, the department also undertakes medical imaging education and research, demanding exceptional stability in equipment operating conditions. However, Hainan's tropical monsoon climate, characterised by year-round high temperatures and humidity, makes conventional air conditioning systems inadequate for meeting the stringent requirements of imaging equipment regarding temperature, humidity, cleanliness, and electromagnetic interference resistance. This has led to increased equipment failure rates and fluctuating image quality, directly impacting diagnostic efficiency and the reliability of research data.

Issues that need resolving:

Environmental control issues constrain departmental development

1. Risk of temperature and humidity control failure: Imaging equipment demands stringent environmental temperature conditions (typically requiring maintenance between 20-24°C), with humidity controlled within 40%-60%. Hainan's annual average humidity exceeds 80%, rendering conventional air conditioning systems prone to issues such as condensation and backflow of condensing water. This may result in electrical circuit short-circuits or mould growth on optical components.

2. Insufficient Cleanliness Risks: Imaging examinations demand high-precision imaging. Airborne dust particles may be attached to equipment detectors or patients' skin surfaces, causing image artifacts or cross-contamination. Traditional air conditioning filtration systems can only intercept particles larger than PM10, failing to meet Imaging departments' requirements for filtering PM2.5 and microorganisms.

3. Electromagnetic interference vulnerabilities: Equipment like MRI machines generate strong magnetic fields during operation. Components in conventional air conditioning systems, such as compressors and fans, may interfere with device signals due to insufficient electromagnetic compatibility, causing image distortion or examination interruptions.

4. Energy efficiency versus operational maintenance conflicts: Imaging departments require round-the-clock operation. Conventional air conditioning systems consume high energy and lack intelligent control functions, leading to persistently high departmental operating costs. Simultaneously, delayed fault response impacts equipment availability rates.

Solution:

WARM customized precision air conditioner: Full-Link Empowerment

To address these issues, WARM Refrigeration Equipment (Shanghai) Co., Ltd. has developed a customized  ‘five-dimension integrated’ precision air conditioner solution for the Imaging Department of Danzhou People's Hospital. This comprehensive approach covers the entire life-cycle from equipment selection, system design to installation&commissioning and ongoing maintenance:

1. Ultra-Stable Temperature and Humidity Control System

Employing dual cooling source falling-film evaporative condensation technology integrated with a full stainless-steel, hermetically sealed air-source heat pump structure, this achieves precise control with temperature fluctuations ≤±0.5°C and humidity fluctuations ≤±2%RH. The unit incorporates rapid defrosting and automatic unloading functions, enabling stable operation under extreme conditions from -20°C to 48°C, thereby comprehensively resolving condensation issues in Hainan's high-humidity environment.

2. Medical-Grade Clean Air Assurance

A four-stage composite filtration system (primary + medium + High efficiency HEPA + activated carbon) achieves 99.97% filtration efficiency for PM0.3 particles while adsorbing volatile organic compounds (VOCs) and odors, ensuring air cleanliness meets ISO 14644-1 Class 8 standards. The unit employs positive pressure air supply design to prevent backflow of external contaminated air, reducing cross-infection risks.

3. Full Electromagnetic Compatibility Design

For strong magnetic field equipment such as MRI scanners, the unit utilizes brushless DC motors, shielded compressors, and low-radiation control circuits. Certified to IEC 60601-1-2 electromagnetic compatibility standards, it ensures ‘zero interference’ cooperative operation with  medical equipment.

4. Intelligent Operation&Maintenance and Energy-saving Optimisation

Equipped with WARM's in-house development of proprietary ‘Cloud Control’ system, it provides real-time monitoring of temperature, humidity, energy consumption and equipment status, supporting remote fault diagnosis and predictive maintenance alerts. The modular design allows scalable configuration to meet demand, achieving high comprehensive energy efficiency ratios. Compared to conventional air conditioning systems, it delivers over 40% energy savings, yielding annual electricity cost reductions exceeding £20,000.

5. Full Life-cycle Service Support

WARM provides full set solutions encompassing design, installation, commissioning, and lifetime maintenance and set up dedicated on-site operations teams to ensure fault response times ≤2 hours and equipment availability ≥99.9%.

Customer benefits:

Environmental upgrades drive high-quality development in departments

1. Significant Enhancement in Diagnostic Quality

Following the operation of precision air conditioning systems, imaging equipment failure rates have decreased by 70%, imaging artifacts have been reduced by 90%, and examination success rates have risen to 99.5%, providing clinical practice with more precise diagnostic evidence. For instance, image distortion issues in MRI examinations caused by environmental interference have been completely resolved, with the detection rate of minor lesions in the brain increasing by 15%.

2. Enhanced Research and Teaching Capabilities

A stable temperature and humidity environment ensures the long-term reliability of research equipment. The department's nationally funded project, ‘Research on Environmental Adaptability of Medical Imaging Equipment in Tropical Regions,’ progressed smoothly, with annual SCI paper publications increasing by 30%. Concurrently, the standardised laboratory environment attracted collaborations with multiple medical schools, establishing the department as a regional teaching demonstration base for medical imaging.

3. Substantial Reduction in Operational Costs

The intelligent energy-saving system reduced the department's annual electricity consumption by 350,000 kWh. Combined with Worm's ‘lease-to-own’ model, initial investment costs were cut by 50%, significantly improving capital turnover efficiency.

4. Continuous Optimisation of Patient Experience

The clean, quiet examination environment (unit noise ≤52dB) reduced patient anxiety. Departmental patient satisfaction rose from 85% to 98%, earning it recognition as the hospital's ‘Humanistic Care Demonstration Department’.
