Decreased HVAC equipment efficiency is usually caused by a combination of factors. Zhejiang Brozer Refrigeration Technology Co., Ltd. understands the importance of efficient equipment operation, and we have incorporated low-energy consumption technologies (such as variable frequency technology) into our product design to address these issues.
1. System Leaks and Refrigerant Shortage
Reason: Refrigerant leaks or insufficient charging can lead to reduced heat exchange efficiency and decreased cooling capacity.
Impact: The coefficient of performance (COP) decreases significantly, leading to increased electricity bills.
Suggestion: Regularly check pipe connections and use professional tools to detect refrigerant pressure and leak points.
2. Evaporator/Condenser Frosting or Fouling
Reason: Clogged air filters or poor condenser heat dissipation can cause the heat exchange surface to be covered.
Impact: Reduced cooling/heating capacity, increased compressor load, and decreased system efficiency.
Suggestion: Regularly clean the heat exchange surfaces to ensure good airflow.
3. Compressor Failure or Aging
Reason: The compressor is the core of the HVAC equipment. If wear or mechanical failure occurs, the compression efficiency will drop significantly.
Impact: Increased system energy consumption, and some failures may lead to system shutdown.
Suggestion: Replace aging components promptly. Our low-temperature screw units and variable frequency compressors are designed for high-efficiency operation.
4. System Overload
Reason: High ambient temperature or poor building insulation causes the air conditioner to handle a larger heat load.
Impact: Long-term operation under high load will lead to decreased efficiency.
Suggestion: Optimize the building envelope or upgrade to a more efficient variable frequency system.
