A comp lete, flexible ser ies<br />
Nine new water chillers and heat pumps from 15 to 38 kW in R410A,<br />
which can be fitt ed wit h t he i nnovati ve AdaptiveFunction Plus control<br />
logic developed by RHOSS S.p.A. in partnership wit h t he U niversity of<br />

LOW ENERGY CONSUMPTION water chillers and heat pumps<br />
The AdaptiveFunction Plu s “Economy” function combines c omfort<br />
with l ow energy c ons umption. I n f act, by adjusti ng the set-point value, it<br />
opti mises compressor operation on the basis of t he actual wor king<br />
conditi ons.<br />
It is thus possible to achi eve significant s easonal energy savi ngs<br />
compared to water chillers and heat pumps of an equivalent power with<br />
traditional control logic.<br />
HIGH PRECISION water chillers and h eat pumps<br />
By using t he AdaptiveFunction Plus “Pr eci sion” function, it is possi ble<br />
to ac hieve as littl e fluct uation as possibl e, at partial capacities , in terms<br />
of t he average s et-point water t emperature deli vered t o t he users.<br />
Guaranteed rel iabil it y, even with water in the pipes onl y<br />
Thanks to the “Virtual T ank” f uncti on, Compac t-Y units with<br />
AdaptiveFunction Plu s can operate i n s ystems wit h a low wat er<br />
cont ent of down to 2 litres/ kW, even without the pres enc e of a water<br />
buffer tank, whilst still guaranteeing the reliability and good working<br />

<strong>TCAEY</strong>-<strong>THAEY</strong> 115÷133 with STANDARD control<br />
TXAEY 117÷133 with control<br />
The AdaptiveFunction control logic makes it possible to adapt the<br />
chiller/heat pump oper ating paramet ers to the wor king conditions of the<br />
system in which it is installed, wor king parti ally as a water buffer tank<br />
simulator. This makes it possibl e to reduces the litres/kW of the system<br />
itself, guaranteeing compr essor safety and the reliability of the machine<br />
over time. Approximatel y 4 litr es/ kW are required in a s yst em fitted with<br />
a chiller with AdaptiveFunction adapti ve c ontrol and at least 10<br />
litres/kW in a system fitted with a chiller without adaptive control.<br />
However, it is evident t hat in process applications where more accurate<br />
wat er temperat ure c ontrol is required, it is always preferable to use a<br />
wat er buff er tank or a great er sys tem wat er content, which guar ant ees<br />
high sys tem t hermal inerti a.<br />

AdaptiveFunction Plus<br />
<strong>TCAEY</strong>-<strong>THAEY</strong> 115÷238 with control<br />
The new AdaptiveFunction Plus adaptive regulation has been<br />
excl usivel y patent ed by RHOSS S.p.A. It is the result of a long<br />
partnership with the University of Padua. The various algorithm<br />
devel opment operations were i mplement ed and validated on units in the<br />
Compact-Y range in the RHOSS S.p.A. R esearc h&Dev elopment<br />
Laborat ory using numerous tes t campaigns.<br />
Objectives<br />
• To guarantee optimal unit operation in the system in which it is<br />
installed. Evolved adaptive logic.<br />
• To obtain the best performance from a chiller in terms of energy<br />
efficienc y at full and partial c apacities. Low consumption chiller.<br />
Operating logic<br />
In general, the actual control logics on water chillers/heat pumps do not<br />
consider the characteristics of t he s ys tem in which t he units are<br />
installed; they usuall y regul ate the ret urn wat er temperat ure and are<br />
positioned so as to ensure the operation of the chillers, giving less<br />
priority to the s ys tem requirements.<br />
The new AdaptiveFunction Plus adaptive logic counters these logics<br />
with the objective of optimising the chiller operation on the basis of the<br />
syst em char acteristics and the ef fecti ve t hermal load. T he c ontr oller<br />
regulates t he deli ver y water t emperature and adjusts itself, as and when<br />
required, to the relative oper ating conditions usi ng:<br />
• the i nfor mation c ont ained in the ret urn and deli ver y water<br />
temperature to estimate the wor king conditions t hanks t o a c ertain<br />
mathematical formula;<br />
• a special adapti ve algorithm that us es this esti mate to vary the<br />
val ues and t he st art-up and s witch- off limit values of t he c ompressors;<br />
the opti mised compress or start-up management guar ant ees a pr ecision<br />
wat er suppl y t o t he user, reduci ng the fluct uati on around the set- point<br />
val ue.<br />
Main functions<br />
Efficiency or Precision<br />
Thanks to the evolved control, it is possible to run the chiller on two<br />
different regulation s etti ngs to obt ain t he bes t possible performance in<br />
terms of energ y ef ficienc y and considerable seas onal savings, or high<br />
wat er delivery temperat ure precision:<br />
1. Low consumption chiller: Economy” option<br />
It is well known that chillers wor k at full capacity for just a ver y small<br />
percentage of t heir operating time, while they wor k at partial capacit y<br />
for most of t he s eas on. Therefore, the power t hey need to s upply<br />
generally diff ers from t he nominal design power, and oper ation at<br />
partial capacit y has a notic eable effec t on seasonal energy<br />
perfor manc e and consumpti on.<br />
This makes it nec essar y t o run the unit s o t hat it is as efficient as<br />
possible at partial c apacit y. T he c ontr oller therefore ensures that t he<br />
wat er delivery temperat ure is as high as possible ( when operating as<br />
a chiller) or as low as possible (when operating as a heat pump)<br />
whilst c ompati ble with the t hermal loads, meani ng that it is on a<br />
sliding scale, unlike in traditi onal s ystems. T his prevents energy<br />
wast age linked t o t he mai ntenance of pointlessl y onerous<br />
temperature levels for the chiller, ensuring that the ratio between the<br />
power t o be supplied and the energy to be us ed t o produce it is<br />
always at an optimum level. Fi nall y t he right level of comfort is<br />
availabl e to everyone!<br />
Summer season: a unit that oper ates wit h a<br />
sliding set-point enables s easonal energy<br />
savi ngs of around 8% c ompared t o a traditi onal<br />
unit t hat operat es with a fi xed s et-point.<br />
W inter season: a unit that operates wit h a<br />
sliding set-point enables s easonal energy<br />
savi ngs of around 13% compared to a<br />
traditional unit t hat operat es with a fi xed s etpoint<br />
. Calculations carried out demonstrate that<br />
seasonal c ons umption is equi val ent to that of a<br />
CLASS A mac hine.<br />
Annual: efficienc y over the annual operation of<br />
the unit i n heat pump mode.<br />
AdaptiveFunction Plu s, with the “Economy”<br />
function, enables the chiller assembly to<br />
operate energy-saving programmes whilst still<br />
providing the required level of service.<br />

2. High precision: “Precision” option<br />
In t his operating mode, the unit wor ks at a fi xed set-point and, thanks to t he delivery water t emper ature control and the evolved regulation logic, at a<br />
capacit y of between 50% and 100% it is possible t o guar ant ee an aver age fluct uati on from the wat er suppl y t emperature of approximatel y ± 1.5° C<br />
from t he set-point value compared to an average fluct uation over ti me of approximatel y ± 3°C, which is normall y obt ained with s tandar d ret urn control.<br />
The “Pr eci sion” option thus guarantees precision and reliability for all those applications that require a regulator that guar antees a more accur ate<br />
const ant water s upply temperat ure, and wher e there are particular damp c ontr ol requirements . However, in process applications it is always<br />
advisable t o us e a wat er buffer t ank or a greater s yst em wat er content t o guarantee higher s ystem t her mal inertia.<br />

Virtual Tank: guaranteed reliability, even with water in the pipes only<br />
A low water content in the system can cause the chiller units/heat pumps to be unreliable and can generate system instability and l ac k of perfor mance.<br />
Thanks to the Virtual Tank function, t his is no longer a problem. T he unit can operat e in s ystems with just 2 litr es/ kW in the pipes given t hat the control<br />
is able to c ompensat e f or the l ac k of inerti a specific to a water buffer tank, " muffling" the control signal, preventing the compressor from s witchi ng on<br />
and off in an unti mel y f ashi on and reducing the average fl uctuation of t he s et-poi nt value.<br />

The chart shows the various chiller outlet temperatures considering capacity of 80%. We can observe how the temperatures of the unit with AdaptiveFunction Plus l ogic<br />
and the Virtual Tank function is far less varied and more stable over time, with average temperatures closer to the working set-point compared to a unit without the Virtual<br />
Tank function. Moreover, we can see how the unit with AdaptiveFunction Plus logic and the Virtual Tank function switches the compressor on less often over the same<br />
period of time, with obvious advantages in terms of energy consumption and system reliability.<br />
ACM Autotuning compressor management<br />
AdaptiveFunction Plu s enables t he C ompact-Y units t o adapt t o t he s yst em they are ser ving, s o as to always identif y the best c ompressor operating<br />
paramet ers in t he diff erent worki ng conditions .<br />
During the initi al operating phases, the special “Autotuning” functi on enables the Compact-Y unit with Ad aptiveFunction Plus to esti mate the thermal<br />
inertia charact eristics that regulat e t he s ys tem dynamics. T he f unc tion, which is aut omaticall y acti vat ed when t he unit is s witc hed on for the first ti me,<br />
executes a number of s et oper ating c ycles, during which it proc esses the inf ormation r elati ve to the wat er temperat ures. I t is thus possible to esti mat e<br />
the physical c harac teristics of the s yst em and t o identif y the opti mal val ue of t he par ameters t o be used f or the control.<br />
At the end of this initi al auto-es timate phase, the “Autotuning” func tion r emains acti ve, making it possible t o adapt the control paramet ers quickl y t o<br />
ever y change in the wat er circuit and thus in the s ystem water cont ents.<br />

Energy efficiency at partial loads - ESEER index<br />
○ The E.E.R. i ndex repres ents an es timate of t he energy efficienc y of<br />
the cooling unit in nominal design conditions. In reality, the operating<br />
time of a chiller in nominal conditions is usually less than the operating<br />
time i n partial load c onditi ons.<br />
○ The E.S.E.E.R. (European Seas onal E. E.R.) is an index t hat<br />
estimates the average seasonal energy efficienc y of the cooling unit i n<br />
four load and wat er temperat ure c onditi ons. Generall y, t wo wat er<br />
chillers with the same E.E.R. may have different E.S.E.E.R. values. In<br />
fact, for a water cooling unit, the average energy efficiency depends on<br />
design choices and on t he t emper ature of i nlet water at t he c ondensing<br />
heat exchanger.<br />
○ The E.S.E.E.R. energy index, introduc ed by t he European<br />
Communit y (Project E.E.C.C.A.C. - Energ y Ef ficienc y and Certificati on<br />
of Central Air Conditioners), is charact erised by t he water t emperatures<br />
(see table “B”) and by the energy weights t hat are assigned to the four<br />
load c onditions consi dered in the calcul ation: 100% , 75%, 50% and<br />
25%.<br />
ESEER =<br />
3xEER 100% +33xEER 75%+41xEER 50% +23xEER 25%<br />
100<br />
where EER100% EER75% EER50% EER25% represent t he<br />
efficienci es of the cooling unit in t he four load conditions and at the<br />
temperatures i ndicat ed in t able “B”.<br />
The dat a is calcul ated usi ng Eurovent methodology. The pump<br />

TXAEY operating principle<br />
○ The ec ological polyvalent s yst em was<br />
designed by RHOSS to provide 2-pipe and 4-<br />
pipe s ys tems with hot wat er from anot her heat<br />
exc hanger (recover y) year-round, as well as<br />
acting as a traditional reversible-cycle water<br />
chiller.<br />
○ The t otal heat rec over y units also allow<br />
efficient energy r ationalisation.<br />
○ The s yst em can operat e in two modes,<br />
which can be sel ected by elec tronic c ontrol.<br />
These are c alled AUTOMATIC and SELECT.<br />
• In AUTOMATIC mode, t he s ystem allows for<br />
full recover y of t he heat of c ondensation and/or<br />
the production of chilled water.<br />
• In SELECT mode, it allows f or the production<br />
of hot water by the sec ondar y or main heat<br />
exchanger.<br />
AUTOMATIC mode - multi-season<br />
○ In this mode the s ystem automatically<br />
manages the r equests for hot or chilled water,<br />
suppl ying chilled water to the main exchanger<br />
and hot wat er to the sec ondar y exchanger,<br />
even simult aneously.<br />
○ Each r equest for hot or cold water is<br />
satisfied independently of ever y other request .<br />
○ When t he s econdary exchanger requires hot<br />
water, the flow of gas delivered from the<br />
compressor is directed towards the recover y. If<br />
chilled wat er is required at t he same time, t he<br />
unit oper ates as a wat er chiller.<br />
○ In AUTOMATIC mode t he unit therefor e has<br />
three possi ble aut omatic operating<br />
configurations:<br />
• AUTOMATIC 1 (A1) - operation as an aircooled<br />
water chiller for the production of chilled<br />
wat er.<br />
• AUTOMATIC 2 (A2) - operati on as a wat er<br />
chiller with total heat recovery for simultaneous<br />
produc tion of hot and c hilled water.<br />
• AUTOMATIC 3 (A3) - operation as a heat<br />
pump f or the production of hot wat er at the<br />
secondar y exchanger (recover y).<br />
operating principle<br />
SELECT mode - multi-season<br />
○ In this mode, based on requests the system<br />
provides hot wat er to the main exchanger<br />
SELECT 1 (S1) or hot water t o t he s econdary<br />
exchanger SELECT 2 (S2). If simultaneous<br />
requests are expect ed, priorit y of operati on<br />
must be est ablished vi a the electronic control.<br />
○ If the reques t f or hot wat er from t he s elect ed<br />
heat exc hanger is completel y satisfied, the hot<br />
gas can be c omplet el y s witched over t o t he<br />
other heat exchanger, provided t his is<br />
requested.<br />
○ The unit is programmed in t he fact or y to<br />
provide hot wat er wit h priorit y assigned to the<br />
secondar y exchanger. You c an however modif y<br />
this set ting from the el ectronic c ontrol panel.<br />
○ To summarise, oper ation in SELECT mode<br />
offers t wo possible automatic c onfigurations:<br />
• SELECT 1 (S1) - operation as a heat pump<br />
for the produc tion of hot wat er at the main<br />
exchanger.<br />
• SELECT 2 (S2) - operation as a heat pump<br />
for the produc tion of hot wat er at the main<br />
exchanger.<br />

The competitive advantages of the<br />
polyvalent system<br />
○ The pol yvalent s yst em was pat ented by<br />
RHOSS S.p.A. to provide for the reques t for<br />
hot and col d wat er, simultaneousl y or<br />
independentl y, with a si ngle unit . This opti mizes<br />
energy consumpti on and makes management<br />
easier.<br />
○ The pol yvalent s yst em is a valid alternati ve<br />
to traditional systems that require the use of a<br />
chiller or heat pump, with use or addition of a<br />
boiler. The advantages derive from t he use of a<br />
single unit, energy s avings due t o high CO Ps,<br />
and the lac k of use of c ombus tible products, s o<br />
that it can be defined as an ecological<br />
pol yvalent mac hine.<br />
○ The s yst em is a versatile f ourth-generation<br />
pol yvalent heat pump. As opposed t o other<br />
pol yvalent units, it meets the t ypical demands of<br />
2-pipe and 4- pipe s ys tems with a single unit<br />
and in a most fl exible manner, so that it c an<br />
even be us ed in existing s yst ems wit h no<br />
modifications required.<br />
○ This pol yval ent unit takes it place on the<br />
mar ket as a unit t hat ensures essential aspects<br />
such as EFFICIENCY, RELIABILITY AND<br />
VERSATILITY.<br />

Calculation of pr essur e drops<br />
The wat er flow rate at t he exchanger is c alculat ed accordi ng to t he<br />
followi ng formula:<br />
○ G = (Q x 860) : ΔT<br />
• Wher e:<br />
G (l/h) = water fl ow rate at the exc hanger;<br />
Q (kW) = exchanged power, which may be QF (for the evaporat or) or<br />
QT (for the condens er), depending on t he exchanger in question;<br />
ΔT (°C) = temperature diff erential;<br />
○ The pr essure drops can be obtai ned from t he RHOSS selection<br />
soft ware and can be read on the graph to the side, or c an be calculated<br />
using the following rough for mula:<br />
Δpw = Δpw nom x (G : G nom )²<br />

Calculation of pr essur e drops<br />
The wat er flow rate at t he exchanger is c alculat ed accordi ng to t he<br />
followi ng formula:<br />
○ G = (Q x 860) : ΔT<br />
• Wher e:<br />
G (l/h) = water fl ow rate at the exc hanger;<br />
Q (kW) = exchanged power, which may be QF (for the evaporat or) or<br />
QT (for the condens er), depending on t he exchanger in question;<br />
ΔT (°C) = temperature diff erential;<br />
○ The pr essure drops can be obtai ned from t he RHOSS selection<br />
soft ware and can be read on the graph to the side, or c an be calculated<br />
using the following rough for mula:<br />

In t his t ype of s ystem, the machi ne is c onnect ed to the primary wat er<br />
circuit with the main exchanger, while the s econdar y exchanger is<br />
connected to the circuit for heating the hot water, as illustrated in the<br />
figure on page 24.<br />
To calculate the mi nimum water c ont ent on the primar y side, ref er to the<br />
previous c ase relati ve to the 4-pi pe s ys tem.<br />
To calculate the mi nimum water c ont ent on the s econdar y side<br />
connected t o t he hot wat er tank, t he following must be taken into<br />
account. T he hot wat er temperat ure may be i nfluenced, especially in<br />
the winter, by the mac hine's nat ural defrosti ng cycles . I n fac t, during the<br />
defrosti ng phase, the mac hine operat es with an i nverted c ycle,<br />
transferring a c ooling capacit y to the wat er that inevitably cools it down.<br />
The change i n hot water t emperature may af fect performance if t he<br />

Application example<br />
A s ystem with a maxi mum ins talled recovering heating capacit y of<br />
Qt installed= 30 kW. A maxi mum per mitted hot water change of dt u =5K.<br />
The sec ondar y circuit c apacit y is calc ulated as follows:<br />
Qt installed (kW) x 18 l/ kW = 30 kW x 18 l/ kW = 540 l<br />
The sec ondar y circuit water cont ent must be at least 540 l. O verlooking<br />
the water c ont ent in t he pipes, t he c ase i n questi on requires a t ank SI<br />
(see figure) wit h a capacit y of at least 540 l. I n pr actice, we recommend<br />
never exceeding dtu=6K and always considering the maximum<br />
