Following the plan of IEA SHC Task 26 (1998 to 2002), solar combisystems can be classified according to two capital aspects; firstly by the calefaction (or cool) accumulator class (the way in which baptize is added to and fatigued from the accumulator catchbasin and its aftereffect on stratification); secondly by the abetting calefaction (or cool) administration class (the way in which non-solar-thermal abetting heaters or coolers can be chip into the system).
Maintaining stratification (the aberration in baptize temperature from acknowledgment at the basal of a catchbasin to warmer at the top) is important so that the combisystem can accumulation hot or air-conditioned baptize and amplitude heating and cooling baptize at altered temperatures.
Heat and air-conditioned accumulator categories Class Description
A No controlled accumulator accessory for amplitude heating and cooling.
B Heat and air-conditioned administration and stratification accessory by agency of assorted tanks and/or by assorted inlet/outlet pipes and/or by three- or four-way valves to ascendancy breeze through the inlet/outlet pipes.
C Heat and air-conditioned administration application accustomed alteration in accumulator tanks and/or amid them to advance stratification to a assertive extent.
D Heat and air-conditioned administration application accustomed alteration in accumulator tanks and congenital stratification devices.
B/D Heat and air-conditioned administration by accustomed alteration in accumulator tanks and congenital stratifiers as able-bodied as assorted tanks and/or assorted inlet/outlet pipes and/or three- or four-way valves to ascendancy breeze through the inlet/outlet pipes.
Auxiliary calefaction and air-conditioned administration categories Class Description
M (mixed mode) The amplitude heating bend is fed from a alone abundance acrimonious by both solar collectors and the abetting heater.
P (parallel mode) The amplitude heating and cooling bend is fed alternatively by the solar collectors (or a solar baptize accumulator tank), or by the abetting boiler or cooler; or there is no hydraulic affiliation amid the solar calefaction and air-conditioned administration and the abetting calefaction emissions.
S (serial mode) The amplitude heating and cooling bend may be fed by the abetting heater, or by both the solar collectors (or a solar baptize accumulator tank) and the abetting boiler affiliated in alternation on the acknowledgment band of the amplitude heating loop.
A solar combisystem may accordingly be declared as getting of blazon B/DS, CS, etc.
Within these types, systems may be configured in abounding altered ways. For the alone abode they may – or may not – accept the accumulator tanks, controls and abetting boiler and acknowledgment chip into a alone prefabricated package. In contrast, there are aswell ample centralised systems confined a amount of properties.
The simplest combisystems – the Blazon A – accept no "controlled accumulator device". Instead they pump balmy (or cool) baptize from the solar collectors through underfloor axial heating pipes anchored in the accurate attic slab. The attic slab is thickened to accommodate thermal accumulation and so that the calefaction and air-conditioned from the pipes (at the basal of the slab) is appear during the evening.
