Supply of Energy-Efficient Commercial HVAC Equipment

    Holtop successfully secured a major contract with Marriott International, one of the world’s leading hotel brands, to provide advanced HVAC solutions for a flagship five-star hotel in China. This project involved the design and supply of customized air handling systems tailored to the hotel’s demanding requirements for comfort, energy efficiency, and reliability. Holtop’s equipment ensures optimal indoor air quality (IAQ) and thermal comfort across diverse zones including guest rooms, lobbies, restaurants, and conference facilities.

Challenges & Requirements

• Energy Efficiency Goals: The hotel sought to reduce operational costs through high-efficiency systems.
• Space Constraints: Compact yet powerful units were needed to fit limited mechanical rooms.

Holtop delivered a tailored package of commercial HVAC equipment, including:

1. Energy Recovery Ventilators (ERVs)

• Quantity: 10 units
• Purpose: Pre-condition incoming fresh air by recovering energy from exhaust air, significantly reducing cooling/heating loads and improving IAQ.2.

2. Dedicated Outdoor Air Systems (DOAS)

• Quantity: 5 units
• Purpose: Deliver 100% fresh, dehumidified air to critical zones like conference rooms and kitchens, ensuring compliance with ASHRAE standards.

3. Modular Air Handling Units (AHUs)

• Quantity: 20 units
• Purpose: Flexible, high-capacity units with anti-corrosion coatings for humid environments, serving guest rooms and public areas.

4. Fan Coil Units (FCUs)

• Quantity: 150 units
• Purpose: Quiet, ceiling-mounted units for individual room control, featuring low noise levels (<35 dB) and seamless integration with building management systems.

Key Outcomes

• Energy Savings: Rotary enthalpy wheels in ERVs reduced HVAC energy consumption by ~30%, aligning with Marriott’s sustainability initiatives.
• Enhanced Guest Experience: Stable temperatures, low humidity, and superior air quality achieved through multi-stage filtration (MERV 8+).

Why Holtop Was Chosen？

• Technical Expertise: Customized solutions based on load calculations and climate-specific challenges.
