Discharge Superheat l Discharge Line Temperature

00:00 Introduction 03:00 Problems because of high discharge line temperature 04:25 Discharge Superheat 06:07 Questions 06:28 Summary Aim :- Discharge Superheat Objectives :- Discharge Temperature Discharge Superheat Introduction:- Compressor discharge temperatures reflect all of the latent heat absorbed in the evaporator, the evaporator superheat, all of the suction line superheat, and all of the heat of compression and motor generated heat at the compressor. It is at the discharge temperature where all of this heat is accumulated and now must start to be rejected in the discharge line and condenser. Problems because of high discharge line temperature Maximum discharge line temperature is 225 °F or 107 °C If discharge temperature goes higher than 225 °F the system may start to fail from worn rings Acid formation Oil break down Oil start vaporize at 350 °F Discharge valve temperature is 75 °F more than discharge line temperature Serious over heating problems happen Discharge Superheat Discharge Superheat  = Discharge line temperature at compressor – Temperature of saturated liquid Example: Discharge Line Temperature = 170 °FTemperature of saturated liquid = 110°F Discharge Superheat = 170 – 110 Discharge Superheat = 60°F It is to be checked when machine is running at 80% LOAD or higher Discharge line temperature should be measure 6” from compressor or service valve Questions What is the maximum discharge line temperature ? If discharge line temperature is 200 °F what will be the temperature of discharge valve ? What is the formula to calculate discharge superheat ? Summary 1) Compressor discharge temperatures reflect all of the latent heat absorbed by system 2) Maximum discharge line temperature is 225 °F or 107 °C 3) Discharge Superheat  = Discharge line temperature at compressor – Temperature of saturated liquid For Course Details, WhatsApp 9082044810 कोर्स की जानकारी के लिए WhatsApp 9082044810 Available Course / उपलब्ध पाठ्यक्रम https://drive.google.com/drive/folder...
