Main Sources of HVAC Equipment Energy Consumption
Energy consumption analysis shows that HVAC system energy consumption is primarily concentrated in the following areas:
1. Compressor power (approximately 45%–55%)
This is the core drive unit of the system and is affected by refrigerant charge, compression ratio, and operating load.
2. Fan/Pump power (approximately 20%–30%)
This includes the condenser fan, evaporator fan, and cooling water pump. Pipeline resistance and fan efficiency are key factors.
3. Control and Auxiliary Equipment (approximately 10%)
The cumulative standby power consumption of the variable frequency drive, valve actuator, and sensors is calculated. 4. Heat loss and leakage (approximately 10%–15%)
Energy waste caused by leaks or poor insulation in pipes, valves, and condensers.
How to control HVAC Equipment noise in HVAC equipment?
HVAC Equipment noise control measures
Noise is a significant factor affecting the working environment in workshops and cold storage. Zhejiang Brozer Refrigeration Technology Co., Ltd. offers the following noise reduction solutions:
1. Low-noise compressors and variable frequency drives
The low-vibration design of screw compressors, combined with soft start and variable frequency speed regulation, reduces startup shock noise.
2. Silent fan blades and vibration damping brackets
Aerodynamically optimized fan blades, combined with elastic vibration damping brackets, significantly reduce fan noise.
3. Soundproof enclosures and silencer ducts
High-noise units (such as compressors and condensers) are enclosed in soundproof enclosures, and silencer valves and sound-absorbing materials are used on the piping. 4. Vibration Monitoring and Maintenance
Install vibration sensors to monitor equipment operating status in real time and promptly replace worn bearings or loose bolts to prevent escalating noise.
5. Reasonable Layout and Anti-Resonance Design
During the factory and cold storage design phase, plan equipment layout to minimize resonance transmission and utilize anti-resonance padding for isolation.
