    Advanced Ultrasonic Heat Pump

    The Advanced Ultrasonic Heat Pump (AUHP) from Vhault Systems is a fully compressor-free thermoacoustic system that harnesses high-intensity ultrasonic waves to drive heat transfer with breakthrough efficiency and simplicity.

    Powerful standing acoustic waves are generated in a sealed resonant chamber filled with a specialized proprietary refrigerant (not helium-based). These waves produce extreme pressure oscillations that pump heat from a cold source to a hot sink—delivering heating, cooling, or simultaneous operation with extraordinary Coefficients of Performance (COPs routinely exceeding 6–10 in real-world conditions, with potential for even higher in optimized configurations).

    Key Features

    • Zero moving parts → Virtually silent operation, negligible maintenance, and system lifespans of 30+ years
    • Exceptional energy efficiency → COPs 50–300 % higher than conventional vapor-compression systems
    • Specialized proprietary refrigerant → Ultra-low-GWP, zero ozone depletion potential, environmentally responsible formulation
    • No thermal byproduct → Advanced insulation and thermal management eliminate unintended heat losses
    • Compact footprint → Significantly smaller physical size than traditional systems at equivalent capacity
    • Plug-and-play design → Modular components enable rapid installation and seamless retrofit into existing infrastructure

    General Technical Specifications

    • Capacity range: 1–500+ tons (scalable modular configurations)
    • Temperature lift: Ambient cooling to high-grade heat delivery up to 150–200 °C
    • COP (heating/cooling): 6–10+ (application-dependent; real-world measured)
    • Noise level: <30 dBA at full load (near-inaudible)
    • Power input: Standard single- or three-phase electrical supply
    • Refrigerant charge: Minimal sealed volume, zero leak risk
    • Dimensions (example 10-ton unit): Approximately 50–70 % smaller footprint than comparable compressor-based systems
    • Operating lifetime: 30–40 years with minimal service

    Benefits for a Sustainable Future

    The AUHP delivers true net-zero-compatible performance with no mechanical wear, no noise pollution, and no harmful emissions. Smaller units at the same capacity scale, combined with plug-and-play installation, make transition from legacy HVAC systems fast and cost-effective.

    Applications Across Scales

    Residential & Light Commercial (1–20 tons) Whisper-quiet, ultra-efficient heating, cooling, and hot water for homes and small buildings.

    Commercial & District Systems (20–100 tons) Precise climate control and massive heat rejection for offices, campuses, and AI data centers.

    Industrial & Utility-Scale (>100 tons) Waste heat recovery, process heating, and thermal storage integration for heavy industry and district energy networks.

    Vacuum Driven Auto Refrigeration System (VDARS)

    Ultra-Low-Temperature Cooling with a Single Vacuum Pump

    The Vacuum Driven Auto Refrigeration System (VDARS) from Vhault Systems achieves deep and cryogenic cooling through a single vacuum pump and proprietary refrigerant mixture that automatically creates cascading evaporation stages in a closed loop—no compressors, no complex external staging.

    Phase separation occurs naturally under vacuum, enabling precise temperature control from -80 °C to milli-Kelvin ranges with minimal energy input.

    Key Features

    • Only one moving part (single vacuum pump) → Extreme reliability, low maintenance, and silent/vibration-free operation
    • Superior efficiency → Dramatically lower power consumption than traditional cascade systems
    • Application-specific refrigerants → Propane for standard deep cooling; nitrogen or neon/helium hybrids for cryogenic variants—all natural or ultra-low-GWP
    • No thermal byproduct → Advanced insulation and thermal management prevent unintended heat losses
    • Compact footprint → Much smaller physical size than equivalent-capacity conventional systems
    • Plug-and-play design → Standardized interfaces for rapid deployment and easy retrofit

    General Technical Specifications

    • Capacity range: 1–500+ tons (modular and scalable)
    • Temperature range:
      • Standard: -80 °C and below
      • Advanced cryogenic variants: below -180 °C, down to 20 K and 1 K
    • Temperature stability: ±0.1 K (advanced configurations)
    • Pull-down time: Rapid response with minimal overshoot
    • Noise level: <35 dBA at full load
    • Power input: Standard electrical supply; vacuum pump optimized for efficiency
    • Refrigerant options: Propane (deep cooling), nitrogen (mid-cryogenic), neon/helium hybrids (ultra-low cryogenic)
    • Dimensions (example 10-ton unit): 60–80 % smaller footprint than comparable multi-stage systems
    • Operating lifetime: 25–35 years with routine vacuum pump service only

    Benefits for a Sustainable Future

    VDARS eliminates the complexity, energy waste, and environmental risks of legacy cryogenic systems while delivering smaller, more efficient units at the same capacity scale. Plug-and-play installation accelerates adoption in critical infrastructure.

    Applications Across Scales

    Hospitals, Laboratories, and Medical Storage (-80 °C and below) Vibration-free, ultra-reliable storage for vaccines, biologics, and research samples.

    Large-Scale Subcooling and Industrial Refrigeration (>100 tons) High-capacity cooling for food processing, cold warehouses, and AI data center subcooling.

    Cryogenic and Utility-Scale Systems (below -180 °C to 1 K) Air/gas liquefaction, quantum computing facilities, superconducting infrastructure, and advanced research requiring milli-Kelvin stability.
