① Material Selection
Exterior: Stainless steel (anti-corrosion, easy to clean) or powder-coated steel.
Insulation: High-density polyurethane foam (excellent thermal retention).
Interior: Medical-grade stainless steel (antibacterial, rust-proof).
Sealing: Heavy-duty rubber gaskets (airtight closure).
② Structural Assembly
The outer and inner shells are welded/fitted together.
Polyurethane foam is injected for insulation.
Reinforced hinges and locking mechanisms are installed.
③ Cooling System Installation
Compressor: High-efficiency, low-noise refrigeration compressor.
Evaporator & Condenser: Optimized for rapid cooling and temperature stability.
④ Electrical & Control System
Digital thermostat (precise temperature control, typically 2°C to 8°C).
Alarm system (temperature deviation/power failure alerts).
Optional features: UV disinfection, rolling rails, or dual compartments.
⑤ Quality Testing
Leakage Test: Ensures airtight sealing.
Cooling Test: Verifies stable temperature maintenance.
Durability Check: Hinges, locks, and compressor endurance.
2. Working Principle
Mortuary refrigerators operate similarly to medical cold storage units, using a vapor-compression refrigeration cycle:
Compression: The refrigerant gas is compressed, increasing its temperature and pressure.
Condensation: Hot gas flows through condenser coils, dissipating heat and turning into liquid.
Expansion: The liquid refrigerant passes through an expansion valve, dropping pressure and temperature.
Evaporation: Cold refrigerant absorbs heat from the cabinet interior via evaporator coils, cooling the chamber.
Repeat Cycle: The refrigerant returns to the compressor, and the cycle continues.
Key Features for Mortuary Use:
Uniform Cooling: Airflow design prevents temperature fluctuations.
Hygienic Preservation: Prevents decomposition and bacterial growth.
Silent Operation: Low-noise compressors suitable for funeral homes.
3. Applications
Temporary preservation of deceased bodies (hospitals, funeral homes).
Disaster management & forensic storage.
High-capacity models for mass casualty events.
