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.

(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 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
(YLCA/YLHA), see on page 4
