The refrigeration capacity of a compressor is the product of the evaporator enthalpy. Calculation of thermodynamic properties used to predict the compressor.
A warmth pump transfers energy by shifting a refrigerant, which alternately absorbs and releases high temperature.This procedure cools refrigerators, freezers and whole areas and structures through heating system, ventilating and surroundings conditioning (HVAC) applications. Some refrigerants are natural. Some are inorganic. Some are cyclic, and some are usually linear. Some are structured on methane, and some are based on longer co2 stores. Each refrigerant has its personal capacity for moving heat. The higher its capacity, the even more warmth it exchanges when it goes at a collection price.
Divide the high temperature water pump's output, in United kingdom Thermal Devices (BTUs), by 2,930. If it transfers 150,000 BTUs per hr: 150,000 / 2,930 = 51.2 kilowatts.
Divide the quantity of refrigerant that the temperature pump goes by the period it takes to proceed it. If it pumps 3.6 kilos of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilos per second.
Divide the reply to phase 1 by the answer to stage 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.

Hi,
I was trying to manufacture a one phase refridgeration cpu-cooIer for my computer. I have got found a number of nice small compressors that I believe would be ideal for the job. Example documents: http://www.aspéncompressor.com/Download%20Pdf/AspenUniversalQuietCompressorSpecSheetJan2014.pdf
I would like to understand how to manufacture a small single stage cooling system from fundamental theory to an actual working chilling system and selecting components, so that the program will arrive close to what I built in theory. I make use of coolpack software program for the log-ph layouts, but I feel trapped at how to combine the theory of these layouts to the téstconditions in the manufacturers documents. Which parameter óf the compressor thát the manufacturer provides, can not really be changed and consequently be used to determine the cooling-output in different situations?
Will anyone by any possibility have some guidance on how to go about, or fine examples how I cán recalculate how much a particular single phase refrigeration compressor can deal with in a different condition then it is tested at?
