“The inverter compressor is the best invention within the HVAC trade in my lifetime.”

I’ve repeatedly made that assertion on this column and in my TOSOT mini break up and APEX coaching occasions. I stay dedicated to it and provide the next as additional proof to assist it

There was a characteristic of the TOSOT multi-zone mini break up that I had been apprehensive about utilizing myself in a residential utility once I was nonetheless contracting and one which I had problem describing objectively as a coach.

Options and Elements of the Inverter Mini Cut up

The characteristic is the flexibility to put in extra indoor capability than outside capability. In my coaching occasions, I nearly have a tough time finishing that sentence as a result of, on the floor, it appears so mistaken. Nevertheless, like most options and parts of the inverter mini break up, we have to scratch under the floor a bit of bit to uncover the true benefit.

Trying on the chart of authorized TOSOT Commonplace Multi-Zone mixtures, you’ll discover that 73 of the 123 authorized mixtures even have extra indoor capability than outside capability … how can that be?

Nicely, clearly, you’re at all times restricted to the capability of the outside unit. Nonetheless, once you look intently on the capacities of the TOSOT Commonplace Multi-Zone outside items, you see that the 18K, 24K and 30K outside unit capability vary exceeds the capability acknowledged of their mannequin quantity for each cooling & heating.

As well as, additionally, you will discover that the 36K and 42K exceed the capability acknowledged of their mannequin quantity for heating. So, after we take a look at the authorized mixture of 9+9+9 for the TM24H4-O, at first look, it seems we now have 3K extra indoor capability than the 24K outside unit.

Nevertheless, a better examination reveals that the TM24H4-O has a capability for cooling to 33K and heating to 28K … greater than sufficient to deal with the 27K of indoor items!

Now, please word that not the entire authorized mixtures work out this manner … many nonetheless symbolize extra indoor capability than outside and in these cases, ought to all indoor items name concurrently, the system is restricted to the general capability of the outside unit which can consequence within the indoor items de-rating. This characteristic is one more instance of the ability of the inverter compressor as a modulating compressor.

My instance of the 9+9+9 with the TM24H4-O exemplifies how as a substitute of going to the TM30H4-O outside unit, you’ll be able to maintain your gear price down but nonetheless preserve crucial capability for any climate occasion … finally serving to you get the job!

I used the Commonplace Multi-Zone outside unit in my instance however the identical applies to the UltraHeat Multi-Zone as nicely …

Remaining Ideas

I like that even in any case my years with the TOSOT product, I nonetheless discover revelations like this to excite me and trigger me to rethink earlier considerations.

The inverter compressor IS the best invention within the HVAC trade in my lifetime. It continues to impress with its capacity to make what was as soon as unthinkable now potential!
