1.4 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 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:
Cooling capacity kW = l/h cold water x differential °C
860
Installation manual 1
Selection guide (YLCA/YLHA) 1.4
SELECTION EXAMPLE
A cooler is required to chill water from 13°C to 7°C, with a cooling capacity of 5 kW.
There are also other design conditions:
• Inlet ambient air in the condenser 35 °C
• Fouling factor: 0,044 m
2
°C/kW
• Altitude: Sea level
From a quick glance at the table
Cooling capacities YLCA 5 ÷ 27 , see on page 28 it can be seen that
a YLCA 5 gives approximately the required capacity of 5,38 kW.
As the factors appearing in tables
, see on page 9 and
Altitude factors , see on page
12 are not applicable, the conditions will be as follows:
• Cooling capacity: 5,38 kW
• Power consumed: 1,87 kW
• Water temperature: 13°C to 7°C (Temp. difference of 6)
Water flow rate =
5,38 x 860
6
= 771 l/h
Available pressure in the unit's hydraulic circuit:
• From Table
, see on page 13 we infer that the YLCA 5 MC, with a flow rate of 771 l/h, has an available pressure of 56 kPa.
Pressure drop in filter:
• From Table
Pressure drop in filters , see on page 14 we infer that with a flow rate of 771 l/h, there is
a pressure drop of 1,3 kPa.
YLHA PLUS selection method
1 Establish the correct size of YLHA PLUS by selecting the model from the tables
YLHA 5 ÷ 27 , see on page 27 and
Cooling capacities YLCA 5 ÷ 27
, see on page 28 that is closest to the cooling and heating capacities required in design conditions of the water outlet temperature and air inlet temperature.
2 Apply fouling correction factors (table
, see on page 9) and height correction factors
Altitude factors , see on page 12) to the capacity and power values shown in the corresponding
tables of capacity for the cool and heat modes. 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 PLUS operating limits.

Selection guide (YLCA/YLHA)
YLHA PLUS SELECTION EXAMPLE
A YLHA PLUS 5 heat pump operating at a 35 °C ambient temperature should cool water from 13 °C to
7 °C, with a 5 kW cooling capacity.
A 4 kW heating capacity is required in 0 °C design ambient temperature and a hot water outlet temper‐ ature of 45 °C.
The fouling factor is 0,044 m
2
°C/kW, with the unit operating at sea level (no corrections). From a quick glance at the tables
Heating capacities YLHA 5 ÷ 27
, see on page 27 and
÷ 27 , see on page 28 we see that a YLHA PLUS 5 heat pump approximately gives the required ca‐
pacities:
• Cooling capacity = 5,4 kW
• Total unit absorbed power = 1,91 kW
• Cold water temperature = 13 °C to 7 °C (Temp. diff. of 6 °C)
• Hot and cold water flow rate = 774 l/h
• Heating capacity = 4,15 kW
• Total unit absorbed power in heat mode = 1,88 kW
• Hot water outlet temperature = 45 °C
Hot water temp. dif‐ ferential
=
4,15 x 860
774
= 4,60 °C
Thus, hot water return temperature is = 40,4 °C
All values are within operating limits:
• Available pressure in hydraulic circuit of a unit with pack:
, see on page 13 we infer that the YLHA PLUS 5 MC, with a flow rate of 748 l/h, has an available pressure of 56,5 kPa.
• Pressure drop in filter.
, see on page 14, 1" filter, we infer that with a 748 l/h flow rate, said filter has a pressure drop of 1,2 kPa.

Installation manual 1
Selection guide (YLCA/YLHA) 1.4
1.4.1 Selection guide with glycol (cool only units)
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:
Capacity (kW) =
Temp. diff. (°C) x Flow rate (litres/sec.)
Glycol factor
Temp. differential (°C) = Liquid Inlet Temp. ‑ Liquid Outlet Temp.
To determine the glycol factor, please see
Glycol concentration and correcting tables
, see on page
10 (Recommended ethylene glycol concentrations) for ethylene glycol or (Recommended propylene glycol concentrations) for propylene glycol. For design outlet temperature, please see the recommended 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 deter‐
Glycol concentration and correcting tables , see on page 10 (Ethylene glycol in other
concentrations) or (Propylene glycol in other concentrations).
Selection method
1 Determine the correct cooling unit 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
, see on page 4.
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 a to ‑4 °C, with an output of 3,5 kW.
The following design conditions are applicable:
• Fouling factor: 0,088m °C/kW
• Altitude: 1 200m
• Ambient air: 30 °C
• Glycol concentration: 30% w/w
For a ‑4 °C ethylene glycol outlet, the concentration recommended in Figure 1 is 30%. Therefore, the specified concentration is appropriate.
Cooling capacities YLCA 5 ÷ 27 (35% ethylene glycol)
, see on page 29, we infer that a
YLCA 5 unit, at the established design conditions, gives a capacity of 3,4 kW and a consumption of 1,35 kW.
With the design fouling factor, use the capacity correcting factors x 0,987 and power x 0,995 (see
Fouling factors , see on page 9).
On design altitude, apply the capacity correcting factors x 10,973 and power x 1,020 (see
Altitude fac‐ tors , see on page 12).

1.4
Selection guide (YLCA/YLHA)
On design glycol concentration, apply the capacity correcting factors x 1,015 and power x 1,005
Correcting factors for other glycol concentrations , see on page 12).
Applying these factors to the selection: YLCA 5
Capacity = 3,44 x 0,987 x 0,973 x 1,015 = 3,35 kW
Comp. power = 1,35 x 0,995 x 1,020 x 1,005 = 1,37 kW
For the specified glycol concentration and a ‑4 °C outlet temperature, Figure 3 shows a 0,248 glycol factor. Thus, the flow rate can be determined with the formula appearing in
, see on page 4.
3,35 [kW] =
(1 ‑ (-4)) x Flow rate [l / s]
0,248
Flow rate =
3,35 x 0,248
5
= 0,166 [l / s] or 598 [l / h]
This covers the Limits of Use.
The evaporator pressure drop can be determined by taking the water pressure drop value for a YLCA unit and multiplying it by the correction factor (see
Glycol concentration and correcting tables
, see on page 10) for a 30% concentration and an average temperature of ‑1,5 °C, i.e.:
-1,5 °C=
1 + (-4)
2
42 kPa x 1,22 = 51,2 kPa.

1.9.3 Hydraulic connections
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 keep‐ ing in mind the pressure drops at said connections and in the internal exchanger of the installation.
Pump dimensioning should be carried out in accordance with a nominal flow rate that allows an Ģt within the operating limits.
During the winter season, with outdoor temperatures below 0 °C, take precautions to avoid freezing of the water in the pipes.
Usually, a filling solution is applied to the circuit with an antifreeze mixture (glycol).

1.10.1 Rotational direction of Scroll compressors
The Scroll compressors only operate correctly in one direction of rotation. Although these units are pro‐ tected by a phase order detector, when the unit is started, check that the unit rotates in the correct direction. If it is not correct:
If the compressors are not connected correctly and are rotating in the wrong direction:
• The compressor will not compress.
• Operating noise will be abnormal.
• Electricity consumption (A) will be low.
• They overheat.
The phase detector must have both LEDs lit for correct operation:
• Green LED lit means: Power ON.
• Yellow LED lit means: Relay ON.
