Vapor compression refrigeration cycle
Refrigerators and heat pumps transfer heat from a low-temperature medium to a high-temperature medium. They differ only in their objectives - refrigerators remove heat (cooling), while heat pumps supply heat.
The vapor-compression cycle is the most common refrigeration cycle. It involves four main components: evaporator, compressor, condenser, and expansion valve. Heat is absorbed in the evaporator and rejected in the condenser. The compressor raises the refrigerant pressure and temperature between these components.
The performance of vapor-compression refrigeration systems depends on factors like evaporator/condenser temperatures and pressures. Actual cycles are less efficient than ideal cycles due to irreversibilities like heat transfer across a temperature
Simple Vapour Compression Refrigeration System
The document discusses the simple vapor compression refrigeration system. It begins by defining what a vapor compression refrigeration system is and why they are needed over other refrigeration systems. It then outlines the basic mechanism and components of a simple vapor compression refrigeration cycle, including the compressor, condenser, expansion device, and evaporator. Finally, it discusses factors that affect the system's coefficient of performance and lists some advantages and disadvantages.
Refrigeration and Air conditioning
The document discusses refrigeration systems and concepts. It provides:
1) An overview of the vapor compression refrigeration cycle, which involves compression, condensation, expansion, and evaporation of a refrigerant to transfer heat from a low temperature to a high temperature.
2) Descriptions of the main components in the cycle, including the evaporator, compressor, condenser, expansion device, and refrigerants used.
3) An introduction to absorption refrigeration systems which use heat energy rather than mechanical work to provide refrigeration.
4) Examples of refrigeration systems like domestic refrigerators and ice plants which use the vapor compression cycle.
Refrigeration and air conditioning
The document discusses refrigeration and air conditioning. It defines refrigeration as the process of removing heat from an object to lower its temperature below the surrounding area. A refrigerator is equipment that produces and maintains a lower temperature in an enclosed space. Refrigerants are fluids that absorb heat from the cooled object and reject it at a higher temperature. Common refrigerants have low freezing/boiling points and are non-explosive/flammable/corrosive. Refrigeration has applications in food preservation, medicine storage, and industrial processes. The document also defines air conditioning and discusses psychrometrics, the study of air and moisture properties. It describes different air conditioning systems and components.
Refrigerent AND ITS NOMENCLATURE RAC
A refrigerant is a working fluid that transfers heat from a cold body to a hot body during the refrigeration process. Traditionally, only a few substances like ammonia, carbon dioxide, and sulfur dioxide were used as refrigerants. Now there are many synthetic refrigerants available, particularly fluorinated hydrocarbons known as Freon. An ideal refrigerant has properties such as low condensing pressure and boiling temperature, high critical temperature and heat of vaporization, and is non-corrosive, chemically stable, non-toxic, and inexpensive.
La mont boiler
The La-mont boiler is a modern high pressure water tube boiler that operates at 170 bar pressure and evaporates 45 tons of water per hour at 500 degrees Celsius. It has components like a feed pump, economizer, air preheater, superheater, evaporator tubes, boiler drum, and circulating pump. Water is pumped into the boiler drum and preheated before circulating through the evaporator tubes where it is evaporated into wet steam, which then enters the boiler drum where dry steam is separated off.

BOILER DRAUGHT
Boiler draught refers to the pressure difference between the air inside a boiler furnace and the outside air, which causes the flow of air and flue gases through the boiler. This pressure difference is necessary for proper combustion of fuel and removal of flue gases. Draught can be produced naturally through the use of a chimney, or artificially through mechanical fans or steam jets. Forced draught uses a fan before the furnace to push air and gases through, while induced draught uses a fan at the chimney to pull gases through. Balanced draught combines the two. Mechanical draught allows better control of the pressure but has higher costs than natural or steam jet draught.

Steam Condensers
Steam condensers condense steam into water by removing heat using circulating cooling water. This reduces pressure in the turbine exhaust and increases efficiency. There are two main types: jet condensers where steam and water directly mix, and surface condensers where they are separated by a heat transfer wall, allowing pure condensate reuse. Lower condenser pressures increase thermal efficiency by allowing more expansion through the turbine, though very low pressures risk moisture issues. Vacuum is created from specific volume changes when steam condenses.

Refrigeration Basics
Refrigeration works by removing heat from a space using a refrigerant in a closed loop system. As the refrigerant absorbs heat, it changes state from a liquid to a gas. It is then condensed back to a liquid, releasing the heat. The four main components are the compressor, condenser, metering device, and evaporator. Refrigerants have saturation temperatures where they change state based on pressure. Proper refrigerant charging can be done using pressure/temperature charts and measuring subcooling or superheat.

Finally, it discusses the environmental effects of refrigerants such as ozone depletion and global warming.
Rankine Cycle
Rankine cycle is a thermodynamic cycle that converts heat into work. It uses a water/steam as the working fluid. There are three main types: ideal, reheat, and regeneration. The ideal cycle assumes instantaneous and reversible processes while real cycles are non-reversible. The reheat cycle increases efficiency by reheating steam between turbine stages. The regeneration cycle further improves efficiency by using steam extracted from the turbine to preheat feedwater entering the boiler. Together these modifications help maximize work extraction from high-temperature heat sources like fossil fuels.
PSYCHROMETRY
Psychrometry is the science dealing with air-water vapor mixtures. It studies moist air and its properties like dew point temperature, relative humidity, and dry/wet bulb temperatures. Psychrometric processes involve changes to moist air through sensible heating/cooling, humidifying, dehumidifying, and adiabatic mixing/cooling. The psychrometric chart is used to analyze these processes by plotting air properties and showing lines for temperature, humidity, and enthalpy. It is a useful tool for understanding air conditioning systems and classifying climates.
centrifugal compressors overview
Centrifugal compressors work by imparting kinetic energy to a gas stream using an impeller, converting the dynamic energy into increased static pressure. They have advantages like high throughput capacity and efficiency over a wide operating range, but also disadvantages like discharge pressure limitations. Key components include impellers, diffusers, volutes, casings, shafts, bearings, and seals. Surge, a dangerous condition where flow reverses rapidly, must be controlled. Compressors can operate alone or in multi-stage arrangements with intercoolers. Common drivers are steam turbines, electric motors, and gas turbines.

Refrigeration and air conditioning
The document discusses refrigeration and air conditioning. It defines refrigeration as the process of transferring heat from a low temperature region to a high temperature region to cool a substance. The principle of refrigeration is based on the second law of thermodynamics, which states that heat does not flow from a low to high temperature body without external work. It then describes the vapor compression refrigeration system, which uses a compressor, condenser, expansion valve and evaporator. Current refrigeration methods discussed are vapor compression and vapor absorption. Vapor absorption uses a heat source rather than electricity. Air conditioning alters properties like temperature and humidity of air for comfort or industrial processes, regardless of external conditions. Different types of air conditioning systems are also outlined
Refrigeration cycle
The document summarizes the refrigeration cycle and vapor compression refrigeration system. The refrigeration cycle involves compressing a refrigerant gas, condensing it in a condenser to release heat, expanding the liquid refrigerant which causes it to evaporate and absorb heat, and circulating the cold gas back into the refrigerator. The vapor compression system uses this cycle, with the main components being a compressor, condenser, expansion valve, and evaporator. The compressor increases the refrigerant's pressure and temperature, the condenser cools and condenses it, releasing heat, the expansion valve reduces the pressure and temperature causing evaporation, and the evaporator absorbs heat during evaporation to cool its surroundings.
EME Refrigeration ppt.pptx
Refrigeration is the process of lowering and maintaining a substance's temperature below the ambient temperature. Refrigerants are working fluids that absorb heat in the evaporator and release it in the condenser while undergoing phase changes between liquid and gas. The two main types of refrigeration systems are vapor compression, which uses mechanical energy to circulate refrigerant, and vapor absorption, which is heat-powered. Vapor compression is more common due to lower maintenance costs, while absorption systems have higher capacities and more consistent efficiency at partial loads.
Thermal Power Plant Basic to Knowledge
This document describes the key components and processes involved in a thermal power plant. Water is heated to produce steam, which spins turbines connected to generators to produce electricity. The main components are the boiler, turbines, condenser, cooling tower and auxiliary systems. Coal is pulverized and burned in the boiler to heat water and produce high pressure steam. The steam powers high, intermediate and low pressure turbines in succession to generate electricity before being condensed back into water in the condenser. The water is cooled in the cooling tower and recycled to the boiler to repeat the process.
VAM ppt
The document describes the key components and processes in a vapor absorption refrigeration system:
1) An evaporator where refrigerant vaporizes and absorbs heat, 2) An absorber where refrigerant vapor is absorbed by an absorbent, releasing heat, 3) A generator where heat regenerates the refrigerant and absorbent, and 4) A condenser where refrigerant condenses and liquefies. Heat from a heat source like steam drives the process without the need for a compressor.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 1. KALI CHARAN NIGAM INSTITUTE OF TECHNOLOGY, BANDA LECTURE ON INTRODUCTION TO REFRIGERATION FUNDAMENTAL OF MECHANICAL ENGINEERING (BME101) ( I SEMESTER ) BY : DEEPAK KUMAR YADAV ME DEPARTMENT
- 2. HEAT PUMP Heat pump is a device is used to maintain a higher temperature as compared to surrounding by supplying heat to system. Coefficient of Performance (COP): COP of a heat pump is expressed by ratio of amount of heat delivered to hot body to amount of work required to be done on the system
- 3. REFRIGERATOR Refrigerator is a device is used to maintain a lower temperature as compared to surrounding by absorbing heat from the system. COP of refrigerator
- 5. COMPONENTS OF VAPOUR COMPRESSION REFRIGERATION SYSTEM Compressor: The low pressure and temperature vapour refrigerant from the evaporator is drawn into the compressor through the inlet or suction valve. where it is compressed to high pressure and temperature. The high pressure and temperature vapour refrigerant is discharged into the condenser through the delivery or discharge valve.
- 6. COMPONENTS OF VAPOUR COMPRESSION REFRIGERATION SYSTEM Condenser: The condenser or cooler consists of coils of pipe in which the high pressure and temperature vapour refrigerant is cooled and condensed. The refrigerant, while passing through the condenser, rejects its latent heat to the external surrounding air. Thus hot refrigerant vapour received from the compressor is converted into liquid form in the condenser.
- 7. COMPONENTS OF VAPOUR COMPRESSION REFRIGERATION SYSTEM Receiver: The condensed liquid refrigerant from the condenser is stored in a vessel, known as a receiver, from where it is supplied to the expansion valve or refrigerant control valve.
- 8. COMPONENTS OF VAPOUR COMPRESSION REFRIGERATION SYSTEM Expansion Valve or Throttle Valve: The function of this valve is to allow the liquid refrigerant under high pressure and temperature to pass at a controlled rate after reducing its pressure and temperature. Some of the liquid refrigerant evaporates as it passes through the expansion valve, but the greater portion is vaporized in the evaporator at the low pressure and temperature.
- 9. COMPONENTS OF VAPOUR COMPRESSION REFERIGERATION SYSTEM Evaporator: An evaporator consists of coils of pipe in which the liquid-vapour refrigerant at low pressure and temperature is evaporated and changed into vapour refrigerant at low pressure and temperature.
