How increase in evaporator increases Refrigeration effect?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between the increase in evaporator temperature and its effect on the refrigeration effect in vapor compression systems. Participants explore the implications of this relationship through theoretical and conceptual lenses, referencing TS diagrams and definitions of refrigeration effect.

Discussion Character

  • Conceptual clarification
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses confusion regarding how a higher evaporator temperature can lead to a higher refrigeration effect, noting the apparent contradiction in the TS diagram.
  • Another participant provides a definition of refrigeration effect, emphasizing that it measures the efficiency of the refrigerator in terms of heat absorption rather than the temperature achieved.
  • Repetition of the definition of refrigeration effect is noted, suggesting a focus on understanding its implications rather than the temperature aspect.
  • A participant reiterates their struggle to comprehend the relationship, seeking further clarification and assistance.
  • One participant argues that the discussion is fundamentally about understanding the definition of refrigeration effect, indicating a potential disagreement on the interpretation of the concept.

Areas of Agreement / Disagreement

Participants appear to have differing views on the relationship between evaporator temperature and refrigeration effect, with some emphasizing the definition while others question its implications. The discussion remains unresolved regarding the intuitive understanding of these concepts.

Contextual Notes

Participants reference TS diagrams and specific refrigerants (e.g., R134a) but do not provide detailed mathematical or empirical evidence to support their claims. The discussion reflects varying levels of understanding and interpretation of the refrigeration effect.

It appears very non intuitive to me seeing TS diagram of vapour compression system; Area under the curve increases. But how seriously how higher evaporator temperature will lead to higher refrigeration effect. Refrigeration effect means lower temperature.

Put 'refrigeration effect' in search and you get this ..."Net Refrigeration Effect is. "the quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling"."

Refrigeration effect is a measure of how efficient the refrigerator is (in it's use of fluid), not how cold it gets.

Just see the TS diagram of say taking R134a refrigerant. I am not getting it :( please help

The issue is that you are arguing against a definition. The definition is as @oz93666 said.
