What is condenser capacity?
The condenser capacity is the ability of the condenser to transfer heat from the hot vapour refrigerant to the condensing medium.
How is water cooled condenser capacity calculated?
Sizing Water-Cooled Condensers
12,000 BTU/hr is the normal figure for one ton or horsepower. To this, add 3,000 BTU/hr heat of compression for a total of 15,000 BTU/hr per ton. For medium and low temperature systems, take the actual load and add 3,000 BTU/hr per horsepower.

How do you choose a condenser capacity for a reactor?
Step – 1: Select a solvent having high volatility. Step – 2: Calculate the maximum boil-up of the selected solvent. Step – 3: Calculate the Condenser Capacity for that boil-up. That’s it …!!
How do I choose a condenser?
This being a strategic choice, the condenser unit should consider the specifics from your project, the type of product you want to cool, your production volume, the space, and the outside temperature and climate and geographical conditions of your plant.
How do you calculate condenser efficiency?
The thermal efficiency of a condenser is defined as the ratio of actual rise in temperature of cooling water to the maximum possible rise. ts = saturation temp., corresponding to condenser pressure (i.e., vacuum temp.) Numerical Example : Vacuum in a condenser is found to be 708.5 mm Hg .
What is condenser load?
As the condenser load increases the temperature difference between the air inlet (ambient) temperature and the condensing temperature will increase in order to reject heat at a faster rate with the same surface.
What is cooling capacity in kw?
The cooling capacity of 1 ton is equal to 3.517 kilowatts of power. For 1.5 ton AC, the power consumption is the same as the cooling capacity. There was a value of 1.5* 3.517/2.954 kilowatts.
How do you calculate cooling water flow rate?
- Total Heat Removed. The total heat removed by an air condition chilled-water system can be calculated. h = 500 q dt (1) where. …
- Evaporator Flow Rate. The evaporator water flow rate can be calculated. qe = htons 24 / dt (2) where. …
- Condenser Flow Rate. The condenser water flow rate: qc = htons 30 / dt (3)
How many BTU is 160 square feet?
| Heating Capacity | Square Footage(Hot Climate) | Square Footage(Cold Climate) |
|---|---|---|
| 4,000 BTU | 130 sq ft | 70 sq ft |
| 5,000 BTU | 160 sq ft | 90 sq ft |
| 6,000 BTU | 200 sq ft | 105 sq ft |
| 9,000 BTU | 300 sq ft | 160 sq ft |
How do you calculate heat transfer in a condenser?
- The main basic Heat Exchanger equation is: Q = U x A x ΔTm =
- The log mean temperature difference ΔTm is: ΔTm =
- (T1 – t2) – (T2 – t1) = °F.
- T1 = Inlet tube side fluid temperature; t2 = Outlet shell side fluid temperature;
- ln (T1 – t2) (T2 – t1)

What are the different types of condenser?
A condenser’s function is to allow high pressure and temperature refrigerant vapor to condense and eject heat. There are three main types: air-cooled, evaporative, and water-cooled condensers.
How much is a new AC condenser?
New AC Condenser Prices
The cost of a new AC condenser can range between $850 and $2,700, depending on the size of the unit. The professional labor to have it installed costs an average of $1,750.
How many tons is 1900 square feet?
| ZONE 1 | ZONE 3 | |
|---|---|---|
| 2.5 Tons | 1201 – 1500 sf | 1301 – 1600 sf |
| 3 Tons | 1501 – 1800 sf | 1601 – 1900 sf |
| 3.5 Tons | 1801 – 2100 sf | 1901 – 2200 sf |
| 4 Tons | 2101 – 2400 sf | 2201 – 2600 sf |
How do you size a refrigeration condensing unit?
To find the right condensing unit: Box temperature minus split equals suction temperature. In our example, 40°F – 10°F = 30°F. The unit we want would be shown in a catalog rated at 49,473 BTU/Hr. at 30°F suction temperature.
What are the methods of obtaining maximum vacuum in condenser?
There are various methods used for obtaining maximum possible vacuum in the condenser. (1) Air Pump: The air pumps are used to maintain the desired vacuum in the condenser by extracting the air and other non-condensable gases. The air pumps can remove mixture of condensate and non-condensable gases.
What is condenser unit?
A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along, and a fan for blowing outside air through the heat exchanger section to cool the …
How do you measure condenser length?
…
Re: Condenser Length Problem
- Q = U A LMTD.
- Q = m CP DT for a hot side.
- Q = m CP DT for a cold side.
- m = density * Ac * veocity for hot side.
- m = density * Ac * veocity for a cold side.
Why condenser capacity is always bigger than evaporator?
Condensers have to be larger than evaporators in terms of their heat exchange capacity because they are not only rejecting the heat absorbed by the evaporator… they also need to reject additional heat that the refrigerant gains in the compressor from the heat of compression.
What is cooling capacity of 1.5 ton AC?
Cooling Capacity:
Similarly, if we consider 1.5 Ton AC, the cooling capacity is 18000 BTU/hr, which means 5275 Watt approx. Thus cooling capacity is fixed by the tonnage of AC.

What is cooling capacity in AC watts?
Cooling capacity is the measurement of a cooling system and its ability to remove heat from a space. SI units are watts (W). They can also be described in tons to signal how much water at X temperature can be frozen in X amount of time.
What is cooling capacity 5050 W?
EER- Energy efficiency ratio is measured only one at peak cooling time and maximum outside temperature. EER = Rated Cooling Capacity (W) / Rated Power Consumption (W) Here, Voltas SAC 185 MY, Rated Cooling Capacity (W) is 5050 instead of 5275.5 watts for 1Ton AC. EER = 5050 / 1438 = 3.51 w/w.
