How is IPLV calculated?
The IPLV is calculated by determining the weighted average efficiency at part-load capacities specified by an accepted standard. It is also important to note that IPLVs are typically calculated using the same condensing temperature for each part-load condition and IPLVs do not include cycling or load/unload losses.
How do you calculate kilowatts per ton of chiller?
Electric motor driven chillers are rated in kilowatts per ton cooling.
- kW/ton = 12 / EER.
- kW/ton = 12 / (COP x 3.412)
- COP = EER / 3.412.
- COP = 12 / (kW/ton) / 3.412.
- EER = 12 / (kW/ton)
- EER = COP x 3.412.
How do you calculate kW cooling capacity?
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.
What is the relation between kW ton and COP?
1 kW/ton = 3.516/COP .
What is IPLV value?
IPLV stands for Integrated Part Load Value, it’s a similar concept to SEER, where part-load performance is measured and rated so that customers can have a way to do an apples-to-apples comparison of real-world operating efficiency between various brands and models.
What is NPLV and IPLV?
IPLV stands for integrated part load value and NPLV standfor non standard part load efficiency.
What is IPLV and NPLV in chiller?
IPLV stands for integrated part load value and NPLV standfor non standard part load efficiency. IPLV or NPLV is used to evaluate efficiency of chiller at different loading condition.
How do you convert kW to tons?
Therefore, 1 Ton of cooling = (12,000 BTU/h)*(1 kWh)/(3412.142 BTU) = 3.5168 kW. So if you want to figure out how many Tons of cooling is required for x number of kW of power consumed [or heat generated], simply divide the total kW by 3.5168.
How many kW is in a ton?
The ton (ton of refrigeration) is a unit of power. This tool converts tons to kilowatts (ton to kw) and vice versa. 1 ton ≈ 3.5169 kilowatts. The user must fill one of the two fields and the conversion will become automatically.
Is higher IPLV better?
IPLV represents the cooling efficiency of a unit operating over its entire range of unloading. Unless the unit will operate at or near its full load value 100% of the time, a lower IPLV is more desirable for better overall performance.
What is iplv and how is it calculated?
The IPLV is calculated on the weighted percentage of assumed operational hours at each operating condition. So there are four operating points that are going to be measured. This is an average efficiency of a single chiller. A lot of chiller installations will have multiple chillers.
What is the iplv formula for Chiller efficiency?
The IPLV formula is one over the four operational points that we are calling A, B, C & D. These will be the efficiency of the chiller at the different partial loads, which we’ll get into next. Were going to take condition “A” at 1%, condition “B” at 42%, condition “C” at 45%, and condition “D” 12%.
How do you calculate kW/ton from cop?
kW/ton = 12 / (COP x 3.412) COP = EER / 3.412 COP = 12 / (kW/ton) / 3.412 EER = 12 / (kW/ton)
How do you convert kW/ton to EER?
Convert cooling load units kW/ton, COP and EER 1 kW/ton = 12 / EER 2 kW/ton = 12 / (COP x 3.412) 3 COP = EER / 3.412 4 COP = 12 / (kW/ton) / 3.412 5 EER = 12 / (kW/ton) 6 EER = COP x 3.412
