It will also include any recommendations for efficiency improvements. These could be anything from simple changes to your control settings or a complete system upgrade. Whilst you are not legally obliged to follow these recommendations, there are several benefits to doing so:
- Reduced energy consumption
- Lower carbon emissions
- Decreased running costs
- Increased system longevity
Who Needs a TM44?
A TM44 inspection is required for any air conditioning system that uses a refrigerant as a cooling agent, and has an effective rated output of more than 12kW.
The effective rated output is the maximum calorific output in kW delivered during continuous operation as stated by the manufacturer. You can find this information on the rating plate attached to your system, in its operating manual, or on the manufacturer’s website.
Alternatively, if you have a planned preventive maintenance contract in place, your system’s capacity should be known by your maintenance contractor.
It’s important to note that the 12kW rule does not only apply to single large scale systems, but also to multiple smaller systems that have a combined output of 12kW or more.
How often is a TM44 required
A TM44 inspection is a mandatory requirement that must be carried out no more than five years after the last. In line with the EPB Regulations, the initial inspection of a qualifying system must meet the following:
- for all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when the system was first put into service
- for other air conditioning systems, where the effective rated output is more than 250kW, the first inspection must have taken place by 4 January 2009
- for other air conditioning systems, where the effective rated output is more than 12kW, the first inspection must have taken place by 4 January 2011
