The purpose of a TM44 survey is to assess the efficiency and environmental impact of air conditioning systems to ensure that they are safe and compliant with EPBD (Energy Performance of Buildings Directive).
TM44 air conditioning inspections can help identify and address some of the most common faults in air conditioning systems. Identifying faults can improve system performance, reduce energy consumption, and extend the lifespan of the unit and system.
Frequent Air Conditioning Faults Identified in a TM44 Survey: Key Takeaways
1. A TM44 survey identifies faults like poor maintenance, outdated systems, insufficient insulation, faulty or incorrect settings, and refrigerant leaks.
2. TM44 surveys help improve efficiency and reduce costs.
3. Regular TM44 surveys ensure compliance with legislation provided by the Energy Performance of Buildings Directive, and system optimisation.
Common Faults Identified in a TM44 Survey
The most common faults identified in a TM44 Survey include the following:
Incorrect Settings/Faulty Controls
Faulty controls and incorrect settings are two common faults identified in TM44 inspections. Both can severely impact an air conditioning system's efficiency.
Where settings are incorrect or controls have failed, it can result in inconsistent temperatures and higher energy consumption. It can also prove to be very uncomfortable for occupants.
Poor Maintenance of Filters and Coils
A TM44 survey can help identify areas where routine maintenance has been neglected, leading to the accumulation of dirt and debris on filters. Dirty filters and coils restrict airflow and reduce heat exchange efficiency, forcing the system to work harder and longer to cool the space, resulting in higher operating costs and a shortened lifespan.
Insufficient Insulation for Ducts and Pipework
TM44 air conditioning inspections can also help identify another common fault being insufficient or inadequate insulation on ducts and pipework.
A TM44 survey can help identify whether there is insufficient insulation that can allow heat to enter or escape, thus reducing the efficiency of the air conditioning unit. This fault can make the system work harder to maintain temperature leading to increased energy consumption and operational costs.
Refrigerant Leakages
A TM44 survey often identifies another common fault: refrigerant leaks, which can occur due to wear and tear or damage to the refrigerant system. A refrigerant leak can reduce the unit's capacity, increase energy costs, and, importantly, pose environmental risks.
Obsolete Systems Unsuitable for Modern Efficiency Standards
It is important that a TM44 survey is undertaken on older air conditioning systems as they may not meet current energy efficiency requirements. Outdated systems are often less reliable and cost more to maintain. A TM44 inspection can evaluate the system and its performance to identify whether the system is suitable and compliant or whether it should be upgraded to newer technology.
The Role of a TM44 Survey in Identifying and Addressing Faults
TM44 survey offers a comprehensive inspection and assessment of air conditioning systems. Adhering to TM44 regulations is a legal requirement, failure to ensure compliance can result in hefty fines and other penalties.
The role of a TM44 survey is to provide actionable insights into issues such as poor maintenance, leaks, outdated equipment, etc. before they escalate. By acting on the recommendations of a TM44 inspection, businesses can reduce costs and improve system performance and lifespan.
