How do you calculate the ikW of a chiller?
Performance Assessment Of Chiller Main performance parameter is ikW/TR and it is define by ratio of power input to compressor divided by tons of cooling produced. Lower ikW/TR indicates higher efficiency. COP (Co – efficient of Performance) is define by ratio of EER by 3.413.
What is chiller efficiency?
Calculating the efficiency of a chiller is fairly simple. It is measured in “COP” which stands for Coefficient Of Performance. The Coefficient of performance is just a ratio of the refrigeration effect produced by the chiller against the amount of electrical energy that went into the machine to produce this.
How do you calculate cooling efficiency?
Energy Efficiency Ratio (EER) The EER is a measure of the cooling power of an air conditioning system per unit of power consumed. It is calculated by dividing the cooling power provided by an AC per hour by the number of watts of electricity consumed.
What is TR of chiller?
Ton of Refrigeration (TR): Ton of Refrigeration (abbreviated as TR) is an important historical unit of refrigeration capacity. Originally 1 TR was defined as the rate of heat transfer required to make 1 short ton (2000 lbs) of ice per day from water at 0oC.
What is the best chiller efficiency?
Maximum efficiency occurs with most chillers running at approximately 70-75 percent load and the lowest entering condenser water temperature (ECWT), based on design.
What are the types of cooling towers?
The types of cooling towers based on the air flow generation are Natural draft, Mechanical draft, Cross-flow and Counter-flow towers.
- Natural Draft cooling towers use the design and shape of the tower itself to move up the air naturally using fans.
- Mechanical Draft towers tend to use a fan to force the air.
What is a good chiller COP?
For water cooled chillers, the minimum COP is 4.2 and the minimum IPLV is 5.2; for air cooled chillers the minimum COP is 2.5 and the minimum IPLV is 3.4. In general, water cooled chillers are more compact, less noisy, have longer operating lives and are more energy efficient than air cooled chillers.
What is SI unit of refrigeration?
Explanation: KJ/s or KW is the S.I. unit of refrigeration, which is converted to Tonnes as commercial unit.
How many kW is 1 ton?
3.517 kW
Popular Answers (1) cooling capacity of 1 ton is equal to 3.517 kW of power.
How do you calculate TR?
One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2
How can I make my chiller more efficient?
3 Ways To Increase Chiller Efficiency
- Consider variable speed retrofits. Most components within a chilled water system will benefit from variable speed drives.
- More is less: Running multiple parallel devices optimizes savings.
- Increase supply temperatures.
How to calculate the capacity of your chilling plant?
3000 Kcal = 1TR. =5.32 HOW TO CALCUILATE THE CAPACITY OF YOUR CHILLING PLANT. EXAMPLE: WHAT IS THE TONNAGE OF A CHILLING PLANT IF THE FLOW RATE IS 6 M3/HR & THE INLET TEMPERATURE OF CHILLED WATER IS 30OC AND THE OUTLET TEMPERATURE IS 9OC. Flow :100LPM = 6000 LPH Outlet Temp from Chiller: 9OCentigrade Inlet Temp to chiller: 30OCentigrade
How do you calculate the cooling capacity of a chiller?
It is calculated by comparing the actual cooling capacity to the energy input, usually electricity. The number is derived by dividing Btu’s by watt-hours. An EER rating of 12 = one ton (12000 btu’s) / kWh. Obviously, the higher the EER rating, the more efficient the system.
How many kilowatts per ton for electric chiller?
Electric motor driven chillers are rated in kilowatts per ton cooling. kW/ton = 12 / (COP x 3.412) COP = 12 / (kW/ton) / 3.412. If the efficiency of a chiller is rated to 1 kW/ton, then.
How to calculate EER for a water chiller?
An EER rating of 12 = one ton (12000 btu’s) / kWh. Obviously, the higher the EER rating, the more efficient the system. As far as calculating EER, it is not difficult for a given piece of equipment. You will need to know the btu output. In the case of a chiller, this is the delta T in degrees Fahrenheit times pounds of chilled water per hour.

What is the IKW of A Trane chiller?
In our Site there are 5 chillers of 650 TR (Trane centrifugal type) each and in peaks days almost 4 chillers are running at least 24hrs/days. the IKW given by trane for the chillers is 0.55 to 0.65 but in our site the IKW we are getting is 0.69 to 0.76. what measures can we take to improve our chiller IKW to given level by trane.
