Specifications
Chillers are factory assembled and include all interconnecting refrigerant and wiring pipes ready for field installation. After assembly, the chillers are tested with water. Possible leaks
are also checked after the units are charged with refrigerant.
These units are made of galvanised steel and have corrosion
proof nuts and bolts. The panel can be removed to access
internal components. All external galvanised steel parts are
painted with oven-dried enamel (RAL 9001).
Compressor
The Scroll type hermetic compressor is protected internally.
Starting will be direct on line. The electric sump heater will go
on when the compressor is inoperative. The compressor is
mounted on antivibratory supports.
Evaporating unit
The evaporating unit is an insulated stainless steel plate heat
exchanger. Maximum operating pressure is 30 bar on the refrigerant side, and 6 bar on the water side (relief valve setting). An electric heater and a differential pressure switch are
installed as antifreeze protection.
(For the option without the hydro kit, maximum operating pressure on the water side is 10 bar.)
Air cooled condensing unit
The air cooled condensing unit is made of copper tubing, arranged in staggered rows, mechanically expanded inside high
efficiency aluminium fins. Maximum operating pressure of the
coil is 28 bar (standard unit). For TüV or other European standards, please see Limits of Use.
This air cooled condensing unit is equipped with a progressive fan speed control to optimise output and allow operating
at ambient temperatures of down to -10° C (standard unit, and
-18° C with optional low ambient temperature kit).
Each fan is equipped with a galvanised and painted protection grid. The single-phase fans have IP 44 protection.
Electrical and control panel
All electrical and control components are factory installed, connected and tested. The electric box has a door with an interlocking isolator and contains compressor and fan contactors,
fuses and electrical protection. Also has IP 44 protection.
ECOCONTROL Plus control unit
This control device is electronic and is protected by a plastic
cover. It includes a communication card for B.M.S. (optional)
as well as for a wall-mounted remote control unit (optional).
This remote control unit is user-friendly and has 3 access
levels: user level, maintenance level and factory level with
access limited to maintenance personnel only.
Refrigerant circuit
The refrigerant circuit includes the thermostatic valve, high
and low pressure switches, a filter dryer, a hunidity indicator
(sizes 12 to 36), Schrader valves on high and low pressure
sides of the cooling circuit, and a service valve (sizes 26 to
36). The refrigerant circuit is factory tested for leaks. The suction line pipes are insulated.
(For heat pump models only) A 4-way valve is installed in the
8
cooling circuit to reverse the cycle. It will be activated in cooling mode and during the defrost cycle.
The control includes a defrost operation (for heat pump models).
If defrost is required in heating mode, the cycle is reversed
and the fans go off at the end of the defrost cycle. On models
YCSA/H 26-36, and during the defrost operation, fans are in
operation for 5 seconds every 25 seconds to avoid high discharge pressures.
Pack
The chiller includes a pack with all components needed for
hydro kit operation. This pack is found inside the bed frame
and does not modify the space occupied by the unit. It includes the following components: buffer tank, centrifugal
pump, expansion vessel charged with nitrogen (at 1.5 bar),
relief valve (set to 6 bar), water pressure gauge, two air purging valves, filling valve and drain valve.
Pipes and the buffer tank are preinstalled. The water filter is
supplied loose for field installation (not inside the chiller). An
electric heater protects the buffer tank against freezing.

Heat exchange between the heat transfer liquid (water or
glycoled water) and the refrigerant takes place in the plate
heat exchanger. Water is cooled, and refrigerant is evaporated
and reheated. Then the Scroll type compressor condenses
the refrigerant (gas) until the condensing pressure is reached,
and the refrigerant goes to the air cooled condensing unit. In
the air cooled condensing unit, heat is exchanged between
the unit)
the air and the refrigerant. The air is heated and evacuated
from the chiller (heat rejection). The refrigerant is condensed
and sub-cooled. Then the refrigerant (liquid) goes on to the
expansion valve, where it is expanded until the evaporating
pressure is reached, at which time it goes to the evaporating
unit to start a new cooling cycle.

Cooling cycle
The 4-way valve is activated. Heat exchange takes place
between the heat transfer liquid (water or glycoled water) and
the refrigerant in the plate heat exchanger. Water is cooled,
and refrigerant is evaporated and reheated. Then the Scroll
type compressor condenses the refrigerant (gas) until the condensing pressure is reached, and the refrigerant goes to the
air cooled condensing unit. In the air cooled condensing unit,
heat is exchanged between the air and the refrigerant. The air
is heated and evacuated from the chiller (heat rejection). The
refrigerant is condensed and sub-cooled. Then the refrigerant
(liquid) goes on to the expansion valve, where it is expanded
until the evaporating pressure is reached, at which time it
goes to the evaporating unit to start a new cooling cycle.
14
Heating cycle
The cycle is reversed to heating mode. The 4-way valve is
not activated. The condensing unit becomes the evaporating
unit, and the evaporating unit becomes the condensing unit.
The water in the heat exchanger is heated.
Defrost
When probe ST3 detects a temperature below 0.5° C (factory
set point), the cycle is reversed. The defrost cycle is activated for a maximum of 4 minutes. If, during this period of
time, the temperature rises above +6° C, the defrost cycle is
discontinued.
On models 26-36 and during the defrost cycle, fans run at
maximum speed for 5 seconds, every 25 seconds.

Selection guide (YCSA and YCSA-H)
Necessary information
The following information is needed to select a YCSA water
chiller:
1. Cooling capacity needed.
2. Design cold water input and output temperatures.
3. Design water flow, if any of the temperatures in above
point 2 is unknown.
4. Design input temperature of air to air conditioning unit.
Normally, this will be the design ambient temperature of
summer air, unless influenced by the situation or other
factors.
5. Altitude above sea level.
6. Design gumming coefficient of the evaporating unit.
Note: Points 1, 2 and 3 should be related by means of the
following:
Coolling capacity kW =

- From Table 7 we infer that the YCSA 36 T, with a 5 117 l/h,
flow, has a pressure drop of 38.6 kPa.
Pressure drop in filter.
- From Table 8,1 1/2" filter, we infer that with a 5 117 l/h flow,
said filter has a pressure drop of 3.2 kPa.

Taking a look at Table 1 we can see that YCSA-36, unit gives
an approximate required capacity of 35.7 kW.

All valves are within operating limits.
- Available pressure in hydraulic circuit of a unit with kit.
- From Table 6 we infer that the YCSA-H 36 TP, with a 5
253 l/h flow, has an available pressure of 225 kPa.
- Pressure drop in hydraulic circuit of a unit without kit.
- From Table 7 we infer that the YCSA-H 36 T, with a 5 253
l/h flow, has a pressure drop of 40 kPa.
- Pressure drop in filter.
- From Table 8, 1 1/2" filter, we infer that with a 5 253 l/h
flow, said filter has a pressure drop of 3.5 kPa.
Selection guide with glycol (cool only units)
Necessary information
The following information is needed to select a YCSA water
chiller:
1. Cooling capacity needed.
2. Design cold water/glycol input and output temperatures.
3. Design water/glycol flow.
4. Design input temperture of air to air conditioning unit. Normally, this will be the design ambient temperature of summer air, unless influenced by the situation or other factors.
5. Altitude above sea level.
6. Design gumming coefficient of the evaporating unit.
Note: Points 1, 2 and 3 should be related by means of the
following formulae:
∆t (°C) x Flow (litres/second)
Cooling capacity (kW) =
Glycol factor
In which ∆t = liquid intake temp. - liquid output temp.
Selection example
Achiller is required to chill ethylene glycol from 1 to -4°C with
a capacity of 22 kW.
The following design conditions are applicable:
Gumming coefficient:
0.088m °C/kW
Altitude:
1 200m
Ambient air:
30°C
Concentration of glycol:
30% w/w
For a -4°C, ethylene glycol output, the concentration
recommended in Figure 1 is 30%. Therefore, the specified
concentration is appropriate.
From Table 2 (capacities with 35% glycol), we infor that a
YCSA-36 unit, at the established design conditions, gives a
capacity of 22.8 kW and a consumption of 10.67 kW
(Table 2).
With the desing gumming coefficient, use the capacity
correcting factors x 0.987 and power x 0.995 (Table 9).
On design altitude, apply the capacity correcting factors x
9.973 and power x 1.020 (Table 10).
On design glycol concentration, apply the capacity correcting
factors x 1.015 and power x 1.005 (Table 3).
Applying these factors to the selection: YCSA-36
Capacity = 22.8 x 0.987 x 0.973 x 1.015 = 22.2 KW
To determina the glycol factor, please see Figure 1 for ethylene glycol, or Figure 3 for propylene glycol. For design output
temperature, please see the recommended glycol concentration and the glycol factor in this concentration. This is the
minimum concentration to be used for design output temperature. If a greater concentration is required, the glycol factor
can be determined by means of Figure 2 on ethylene glycol or
Figure 4 on propylene glycol.
Comp. power = 10.67 x 0.995 x 1.020 x 1.005 = 10.88 kW
For the specified glycol conectration and a -4°C output
temperature, Figure 3 shows a 0.248 glycol factor. Thus, the
flow can be determined with the formula appearing in the
"Necessary information" section.
(1 - (-4)) x Flow (l/s)
Selection method
1. Determine the correct size of chiller by selecting the one
that is closest to the capacities required by the design
conditions of the glycol outlet and air intake temperatures.
22.2 kW =
0.248
22.2 x 0.248
Flow =
2. Apply the gumming correcting factors that correspond to
the gumming coefficient, altitude and glycol concentration, and to the capacity tables. Make sure the corrected
capacity is still sufficient for your needs.
3. Using the corrected capacities of the chiller, set the design temperature range, or the flow, to balance the formulae appearing in the "Necessary information" section.
4. Always recheck to make sure these selections are within
the design operating limits.
22
= 1.11 (l/s) or 4 000 (l/h)
5
This covers the limits of use.
The evaporating unit pressure drop can be determined by
taking the water pressure drop value (Table 7) for a YCSA-36
unit and multiplying it by the correcting factor (see Fig. 5) for
a 30% concentration and an average temperature of -1.5°C,
that is to say, 1 + (-4)
= -1.5
2
24 kPa x 1.22 = 29.3 kPa.
