How to read P h Chart explained with Numerical this lecture will explain how to use P H chart for calculating COP, Heat rejected by Condenser, Refrigerating effect, compressor power. Case 1 The Basics of Refrigeration Cycle P H Diagram Analysis Case – 1 The Basics of Refrigeration Cycle P H Diagram Analysis & Refrigerant Flow Diagram Copy Right By: Thomas T.S. Wan (温到祥) Dec. 16, 2006 BASIC KNOWLEDGE THERMODYNAMICS OF THE REFRIGERATION CYCLE The refrigeration cycle in the log p h diagram The refrigeration cycle in the log p h diagram The real refrigeration cycle consists of the following changes of state: 1 – 2 polytropic compression on the condensation pressure (for comparison 1 – 2’ isentropic compression) 2 – 2’’ isobaric cooling, deheating of the superheated steam In addition there are also pressure losses in the ... Basic Refrigeration Cycle Central Air Conditioner And ... Understanding the basic refrigeration cycle diagram also helps us to find subcooled, superheat and to troubleshoot refrigeration processes much easier. As we can see in the Ph diagram below. Saturation curve this curve represents what state (vapor or liquid) and region (sub cooled, latent heat, and superheat) the refrigerant is in. The Pressure Enthalpy Chart The ultimate goal of the refrigeration system is to get the refrigerant into a condition where it can be useful as a medium to transfer heat from the refrigerated space. Refrigeration Pressure Enthalpy Chart Learn various states of a refrigerant by drawing a pressure enthalpy chart. Please provide feedback on this module by selecting "Like" or "Dislike". Refrigeration Diagram on Pressure Enthalpy Diagram for the ... The following sections will show each specific part of the refrigeration cycle on the pressure enthalpy diagram and it will also highlight the important points and calculations needed. Throughout this explanation the refrigerant R 134a is used as an example. Refrigeration Cycle for Ideal conditions on a Pressure Enthalpy Chart Learn how to draw a cycle for ideal conditions on a PH chart. Please provide feedback on this module by selecting "Like" or "Dislike". Your feedback and comments is important to me in developing ... 2.1 The pressure enthalpy diagram SWEP The pressure enthalpy diagram (log P h diagram) is a very useful tool for refrigerant technicians. First, an explanation of how the diagram is built up is given, and then its use is describ ed. PRESSURE ENTHALPY CHARTS AND THEIR USE Figure 4 is a pressure enthalpy diagram of a typical refrigeration cycle in a system with one pound of HFC 134a. It uses (for this example) evaporating and condensing temperatures of 0°F and 120°F. Points on the diagram are labeled to correspond to locations of equipment in the system. Each step of the cycle can be approached separately. At Point 1, the refrigerant leaves the evaporator and ... Understanding the P H Diagram Raffaello Understanding the P H Diagram. The pressure enthalpy diagram or P H diagram is a tool that all HVAC and Refrigeration engineers should be able to use proficiently. Thermodynamics of the refrigeration cycle gunt Refrigeration cycle in the log p h diagram Pressure log p Specifi c enthalpy h Pressure log p Specifi c enthalpy h compressor, condenser, expansion valve, evaporator In addition, pressure losses also occur in the actual refrigeration cycle, so that evaporation and condensation do not take place exactly horizontally (isobarically). Basic knowledge Refrigeration cycle 2 Thermodynamics of the ...
