Selection guide (YLCA/YLHA)

Necessary information
The following information is needed to select a YLCA/YLHA water cooling unit:

1. Cooling capacity needed

2. Design cold water inlet and outlet temperatures.

3. Design water flow rate, if one of the temperatures of Point 2 above is unknown.

4

Quick installation guide

Selection guide (YLCA/YLHA) 1.4

4. Design inlet temperature of air to the condenser. 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 fouling factor of the evaporator.

N O T E

Points 1, 2 and 3 should be related by means of the following formulae:

l/h cold water x differential °C

Cooling capacity kW =

860

SELECTION EXAMPLE

A cooler is required to chill water from 13 °C to 7 °C, with a cooling capacity of 119 kW.

There are also other design conditions:

• Inlet ambient air in the condenser 35 °C

• Fouling factor: 0.044 m2 °C/kW

• Altitude: Sea level

1

Taking a quick look at the table, we can see that a YLCA 120 unit gives an approximate required capacity
of 119 kW.

As the factors appearing in Tables and
will be as follows:

• Cooling capacity: 119 kW

• Power consumed: 40 kW

• Water temperature: 13 °C to 7 °C (Temp. difference of 6)

Water flow rate =

Available pressure in hydraulic circuit of a unit with pack:

• From the table we infer that the YLCA 120 TP, with a 17 056 l/h flow rate, has an available pressure
of 279 kPa.

Pressure drop in hydraulic circuit of a unit without pack:

• From the table we infer that the YLCA 120 T, with a 17 056 l/h flow, has an available pressure drop
of 23 kPa.

Pressure drop in filter:

• From Table
said filter has a pressure drop of 2.4 kPa.

YLHA selection method

1. Determine the correct size of the YLHA unit by selecting a model from Tables 3, 4 and 5 that is closest
to the cooling and heating capacities required in the design conditions of the water outlet and air inlet
temperatures.

2. Apply fouling (Table 11) and altitude (Table 12) correcting factors to the capacity and power values
that appear in the corresponding capacity tables in cool and heat. Make sure the corrected capacity
is still sufficient for your needs.

3. Using the corrected capacities of the unit, select the design temperature differential or the flow rate.

4. Check to make sure that these selections are within the YLCA/YLHA operating limits.

YLHA SELECTION EXAMPLE

A YLHA heat pump operating at a 35°C ambient temperature should chill water from 13°C to 7°C, with
a 112 kW cooling capacity.

A 110 kW heating capacity is required in 5 °C design ambient temperature and a hot water outlet
temperature of 40 °C.

The fouling factor is 0.044 m2 °C/kW, with the unit operating at sea level (no corrections). With a quick
glance of capacity Tables 3 and 5, we see that a YLHA 120 heat pump gives the approximate required
capacities of:

• Cooling capacity = 114 kW

• Total unit absorbed power = 43.2 kW

• Cold water temperature = 13 °C to 7 °C (Temp. diff. of 6 °C)

• Hot and cold water flow = 16 340/h

• Heating capacity = 110.1 kW

• Total unit absorbed power in heat mode = 35.8 kW

• Hot water outlet temperature = 40 °C

Hot water temp. dif‐

ferential

=

110.1 x 860
= 5.8 °C

16 340

Thus, hot water return temperature is = 34.2°C

All values are within operating limits:

• Available pressure in hydraulic circuit of a unit with pack:

• From Table 6 we infer that the YLCA 120, with a 16 340 l/h flow, has an available pressure of 289
kPa.

• Pressure drop in hydraulic circuit of a unit without pack:
– From the table we infer that the YLCA 120, with a 16 340 l/h flow, has an available pressure of 21

kPa.

• Pressure drop in filter.
– From Table

flow rate, said filter has a pressure drop of 2.2 kPa.

1.4.1 Selection guide with glycol (cooling units only)

Necessary information
The following information is needed to select a YLCA cooling unit:

1. Cooling capacity needed

2. Design cold water/glycol inlet and outlet temperatures.

3. Design water/glycol flow rate.

4. Design inlet temperature of air to the condenser. 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 fouling factor of the evaporator.

N O T E

Points 1, 2 and 3 should be related by means of the following formulae:

Temp. diff. (°C) x Flow rate (litres/sec.)

Capacity (kW) =

Glycol factor

Temp. diff. (°C) = Liquid inlet Liquid Inlet ‑ Liquid Outlet Temp.

glycol concentration and the glycol factor in this concentration. This is the minimum concentration to be
used for design outlet temperature. If a greater concentration is required, the glycol factor can be
determined by means of
in other concentrations) or (Propylene glycol in other concentrations).

Selection method

1. Determine the correct cooler model by selecting the one that is closest to the capacities required by

the design conditions of the glycol outlet and air inlet temperatures.

2. Apply the fouling correcting factors that correspond to the fouling, altitude and glycol concentration

factor, to the capacity and power values in the capacity tables. Make sure the corrected capacity is
still sufficient for your needs.

3. Using the corrected capacities of the cooler, set the design temperature range, or the flow rate, to

balance the formulae appearing in

4. Always recheck to make sure these selections are within the specified design limits.

Selection example

A cooler is required to chill ethylene glycol from 1 to ‑4 °C, with an output of 75 kW.

The following design conditions are applicable:

• Fouling factor: 0,088m °C/kW

• Altitude: 1 200m

• Ambient air: 25℃

• Glycol concentration: 30% w/w

Glycol concentration and correcting tables, see on page 9

Glycol concentration and correcting tables, see on page

(Ethylene glycol

Selection guide (YLCA/YLHA), see on page 4

.

For a ‑4 °C ethylene glycol outlet, the concentration recommended in Figure 1 is 30%. Therefore, the
specified concentration is appropriate.

From Table
YLCA-120 unit, at the established design conditions, gives a capacity of 76.8 kW and a consumption of

28.8 kW.

With the design fouling factor, use the capacity correcting factors x 0.987 and power x 0.995 (see

factors, see on page 8

On design altitude, apply the capacity correcting factors x 9.973 and power x 1.020 (see

factors, see on page 11

On design glycol concentration, apply the capacity correcting factors x 1.015 and power x 1.005 (see

Correcting factors for other glycol concentrations, see on page 11

Applying these factors to the selection: YLCA ‑120

Capacity = 76.8 x 0.987 x 0.973 x 1.015 = 74.9 kW

Comp. power = 28.8 x 0.995 x 1.020 x 1.005 = 29.4 kW

For the specified glycol concentration and an outlet temperature of ‑4°C, figure 3 shows a glycol factor
of 0.248. Therefore, the flow rate can be determined with the formula indicated in section

1.6.1 Clearances

When installing each unit, clearances should be left for:

1. Air inlet and discharge.

2. Maintenance servicing.

3. Power supply connections.

For proper operation, all minimum clearances shown on the general dimension diagrams should be
respected always with regard to possible obstruction of air circulation of the work of a user.

1.9 Instructions for installation and connection of the unit

1.9.1 Characteristics of the location

Before locating the unit, make sure you have received the appropriate product by checking the
specifications described on the outside of same.

The unit should be placed on a perfectly horizontal plane, making sure the base can support the weight
of the unit.

If vibration-free operation is required, the unit can be placed on a cork or similar anti-vibratory base, or
fastened to the base with anti-vibratory plates or supports.

1.9.2 Specifications for the foundation or anchoring of the unit

Where the unit is to be installed at ground level, the
characteristics of the ground it will sit on must be taken
into account.

Characteristics, such as acceptable surface firmness,
must be suitable for the foundation the unit requires.

1.9.3 Hydraulic connections

A T T E N T I O N

The water filter must be used whilst the unit is in operation.

A T T E N T I O N

The water circuit connected to the unit must be thoroughly cleaned, in order to prevent dirt from reaching
the plate heat exchanger.

The hydraulic connections of the water inlet and outlet of the unit should be carried out respecting the
inlet and outlet directions indicated.

Galvanised iron or copper piping can be used, with dimensions no lower than those indicated, and
keeping in mind the pressure drops at said connections and in the internal exchanger of the installation.

The pipes and connections should be supplied separately to prevent charges in the heat exchangers.

Flexible connections are recommended to minimise the transmission of vibrations to the structure. They
should be used if the unit is mounted on antivibration supports and if movements of the unit are planned
in normal operation.

Pump dimensioning should be carried out in accordance with a nominal flow rate that allows a Δt within
the operating limits.

1.9 Instructions for installation and connection of the unit

In all cases, a flow switch should be installed so as to avoid the possibility of operation without water
flow.

An adequate expansion vessel for the total volume of the water in the installation should also be installed
in the water return piping.

During the winter season, with outdoor temperatures below 0 °C, take precautions to avoid freezing of
the water in the piping network.

Usually, a filling solution is applied to the circuit with an antifreeze mixture (glycol).

The PH of the circuit water must be between 7 and 8.5.
