subject: Air Conditioning Inspections Provided By Airconditioninginspetion.org [print this page] The TM 44 inspection report: The objective of the TM44 report is to ensure that the building owner or air conditioning operator is provided with adequate information that would allow him to have an understanding of the efficiency of the air conditioning systems for which they are responsible. The TM 44 report also helps them to receive initial advice on how they can make their system more efficient and effective.
Good Practice Inspection and Maintenance of Air Conditioning Equipment: Professional and industry bodies such as CIBSE recommends that all types of comfort cooling systems should be frequently inspected and maintained to the regulation standards as this is considered very important for a number of reasons, such as:
1. Maintaining healthy and comfortable conditions for the building occupants and public
2. Minimising the escape of refrigerant gases that may be harmful to the atmosphere or may contribute to global warming
3. Ensuring safe and efficient operation of the air conditioning equipment which may help to extend its life
What does a TM 44 Report cover?
The TM44 Report comprises of the following major elements:
1. The general condition of the air conditioning system including the indoor and outdoor units.
2. A survey that investigates any faults or errors in the installation and any refrigerant leakage.
3. Identifying banned refrigerants such as R22.
4. Identifying any errors with the programmer such as incorrect date and time.
5. Inspection of blockages in filters and grilles.
In an Air Conditioning Inspection, the TM 44 inspector does not carry out maintenance and nor does he make any adjustment to the system and its controls. Only the above mentioned conditions are identified and it is shown in the inspection report. Then suggestions and recommendations (in Air Conditioning Inspection Report) are given to the operator so that the problems can be resolved to improve its efficiency.
Usually 3 units or 10% of the existing units are chosen during inspection. Normally, the inspector tries to identify the ones with the worse problems and conditions as samples although the recommendation might not apply for all the other similar units. The recommendations can range from cheap/cost-free procedures such as the washing or cleaning of filters to expensive solutions like replacing the entire unit.
The TM 44 assessor usually tries to suggest the most cost effective ad feasible alternatives and the recommendations are written solely to save the operator/building-owner money in maintenance and energy consumption in short and long term.
TM 44 Assessors usually recommend and encourage the use of renewable energies like wind turbines, Photovoltaics, solar panels and CHP (combined heat and power) units. Recommendations such as sub metering do not affect energy consumption directly but it enables us to monitor the energy consumption for effectively and record the impact of the various improvement factors in the heating and cooling systems.
