Improve Chiller Efficiency The Engineering Mindset 6. in this article we’re going to be discussing different ways to improve the efficiency of your existing chiller setup. we’re going to cover compressor retrofit, compressor vfd, chilled water reset, condenser water reset, condenser and evaporator cleaning, expansion valve, air cooled chiller, condenser fans, free cooling or economiser. The electrical power demand of the chiller to produce this is 460kw. the metric calculation would be: 2,500kw 460kw = 5.4 so the cop is 5.4. this means that for every 1kw of electricity you put into the machine, you will produce 5.4kw of cooling. the imperial calculation would be: first convert btu’s to kw’s. 8,533,364btu s 3412.142 = 2.
Improve Chiller Efficiency The Engineering Mindset Pdf Heat The document discusses various ways to improve the efficiency of chillers. it describes retrofitting compressors with newer variable speed technology or variable frequency drives, which can reduce energy consumption by up to 20% by allowing the chiller to perform more efficiently at partial loads. it also recommends implementing chilled water reset strategies to increase chilled water. The evaporator and absorber comprise the bottom most chamber. there is also a heat exchanger to improve the efficiency of the system. how absorption chiller works. first of all a mixture, of around 50% lithium bromide and 40% water, is pumped from the absorber through the heat exchanger and then up into the generator. January 16, 2024. size is often a critical factor in chiller selection. footprint can impact system placement, installation, and scalability. historically, enhancing chiller efficiency has required an increase in overall system size. in air cooled chillers, this was typically driven by increases made to the heat exchanger surface area. The slightest decrease in chiller performance can have a major impact on efficiency. for instance, every 1°f increase in condenser water temperature above full load design can decrease chiller efficiency by 1% to 2%. a failing or neglected water treatment program can reduce efficiency 10% to 35% or more in extreme cases.

Chiller efficiency = power consumption (kw) ÷ chiller capacity (rt) chiller efficiency = 164.9 ÷ (890 x 3412 ÷ 12000) chiller efficiency = 0.65 kw ton. using the same principle, you can always calculate the kw ton of a chiller even though the chiller’s cooling capacity is stated in units other than rt. Blog > maximizing chiller efficiency: some key strategies. chiller efficiency represents a critical factor in assessing a cooling system’s performance as well as every chiller plant’s overall sustainability in both environmental and economic terms. the choice of chiller system plays a critical role in cooling large buildings and.
