In the context of increasingly fierce competition in the hotel industry and the accelerated pace of green and low-carbon development, the central air conditioning system, as the core energy-consuming equipment in hotels, directly impacts operational costs and guest experiences with its energy efficiency and operational quality. Traditional systems commonly suffer from aging equipment, excessive energy consumption, and insufficient temperature control accuracy, making them difficult to meet the diverse demands of modern hotels for energy-saving, environmental protection, comfort, health, and intelligent management.

The hotel's central air conditioning system upgrade is a complex project that requires balancing energy efficiency, user experience, construction management, and cost control. Here is a summary of key considerations:

Central Air Conditioning System Design and Energy Efficiency Optimization

1. Precise Load Calculation

Reassess building thermal loads (such as room count, orientation, and foot traffic) to avoid over-sizing or under-sizing equipment.

2. Regional Control Optimization

Individually control temperature and humidity by function zones (guest rooms, restaurants, lobbies, etc.), utilizing variable air volume (VAV)VAV (Variable Air Volume) or chilled heat separation technology.

3. High-Efficiency Equipment Upgrade

Our company has chosen high-efficiency equipment such as variable-frequency main units and magnetic levitation compressors, paired with intelligent control systems (such as...).Dynamic AI Algorithm Adjustment).

4. Heat Recovery Utilization

Reclaim exhaust air heat for preheating fresh air, or utilize condensate water heat for domestic hot water supply.

Enhanced Air Conditioning System User Experience

1. Silent Design

Select low-noise fan coil units, optimize ductwork layout to prevent vibration transmission to guest rooms.

2. Air Quality Management

IncreasedPM2.5 filtration, UV ultraviolet sterilization, or electrostatic dust removal modules enhance indoor air quality.

3. Precise Temperature and Humidity Control

Utilizing an independent fresh air systemDOAS integrates humidity control to prevent stuffiness or dryness in guest rooms.

4. Intelligent Control

In-room touch panels or mobile phones are provided.The app adjusts temperatures and supports integration with the guest room management system.

Central Air Conditioning Construction and Operation Management

1. Phased construction

Prioritize the renovation of non-commercial areas (such as后勤区), conduct construction in the guestroom area during the off-season, to minimize disturbance to guests.

2. Pipeline and Insulation

Replace aging pipelinesB1-rated fire-resistant insulation material, preventing cold bridge and condensation issues.

3. Compatibility Testing

Ensure compatibility of new equipment with existing systems (such as)Seamless integration with the BA system, pre-testing control logic.

4. Operations and Maintenance Training

New system operation training provided for engineers, maintenance plans established (e.g., quarterly filter cleaning, annual main unit inspection).

Section 4: Central Air Conditioning Costs and Environmental Compliance

1. Investment Return Analysis

Calculate energy saving rate (e.g., expected power saving)30% in subsidies (such as green building incentives) and payback period (typically 3-5 years).

2. Environmentally Friendly Refrigerants

Adopted32, 290, or natural refrigerants (such as CO₂), avoiding obsolete refrigerants (like R-22).

Compliance Approval

Ensure the renovation plan complies with local fire, environmental, and building regulations, and complete the necessary inspection procedures.
