Air cooling systems
Air cooling is a method of dissipating heat by increasing the surface area or airflow over an object's surface. Adding fins to an object's surface increases surface area and improves heat transfer. Using fans to blow air over an object increases airflow and cooling. For air cooling to work, the air must be cooler than the object based on the second law of thermodynamics. Air cooling is commonly used for internal combustion engines in vehicles like motorcycles and aircraft. It is also widely used in industrial processes like air conditioning, power generation, and more.
Presentation on Air cooler // Love Soni
This document describes an air conditioning system that takes hot air from the surrounding environment, cools it using a cooling pad and water, and circulates the cooled air into a room or space. The main components of the system are a fan, motor, capacitor, pump, and cooling pad, which work together to remove heat from incoming hot air and lower the temperature.
Air Flow Sensors
There are two main types of air monitoring devices: mass air flow sensors (MAF) and manifold absolute pressure (MAP) sensors. MAF sensors measure the mass of air entering the engine and are either vane-style or hot-wire sensors. MAP sensors measure vacuum and pressure in the intake manifold.

Report on Air Cooler
An evaporative cooler, also known as a swamp cooler, works by evaporating water which cools dry air through the large enthalpy of vaporization. As warm, dry air passes through a water-soaked pad in the cooler, water evaporates into the air stream, lowering the air temperature while increasing humidity. The working principle relies on the conversion of sensible heat in the air to latent heat of vaporization through an adiabatic process. Evaporative cooling is effective in hot, dry climates as it can significantly lower air temperature using less energy than traditional air conditioning methods.

Induced draught towers bring cooler air into contact with warmer water and allow for larger fans but require more power. Key terms related to cooling towers like fill, drift, approach, and cooling range are also defined.
Diesel engine power plant
Diesel power plants use diesel engines as the prime mover to generate electricity in the range of 2 to 50MW. They are commonly used as backup power sources for critical facilities like hospitals, telephone exchanges, and industries during peak loads. Diesel power plants have several systems, including the air intake system, which draws air through a filter into the engine cylinder. The fuel supply system pumps fuel from a storage tank through a filter and injects it into the cylinder. The exhaust system uses a silencer to reduce noise from the engine gases expelled into the atmosphere. Cooling and lubrication systems are also required to regulate the engine's temperature and reduce wear on moving parts. While diesel power plants have advantages like simple design, quick start

Why compressed air is so expensive and what to do about it
This document discusses why compressed air is so expensive and what can be done to improve efficiency. It notes that typical compressed air systems have poor production efficiency due to factors like leaks, pressure losses, and inefficient equipment. Several "secrets" to improving efficiency are outlined, including producing compressed air more efficiently, using less air, and capturing waste heat. Specific strategies proposed include reducing system pressure and associated losses, improving compressor controls, reducing transmission losses through piping upgrades, and decreasing demand through leak repairs and eliminating inappropriate uses. The presentation encourages addressing both the supply and demand sides to lower the high costs of compressed air.

LING JEN UNG
- 2. INTRODUCTION • Recently a hydraulically driven engine cooling fan is becoming a mainstream technology as one of the means to bring down the level of noises generated by construction equipment • However, the currently available system is no better than a small combination of various general purpose- devices such as a hydraulic pump and motor and valves
- 3. Function of cooling fan • The cooling fan circulates air through the radiator so it can release engine heat into the surrounding air. • With the introduction of fan clutches and electric cooling fans, fans have become more efficient by operating only when they need to. • Electric cooling fans also improve the operation of the air conditioning system.
- 4. Types of Fan 1. Mechanical fan • Mechanical fan is also called belt drive • Mechanical fans are still used on some cars and light trucks • These fans now use a temperature-sensitive fan clutch that allows the fan to disengage and engage according to different operating conditions
- 5. Advantages Disadvantages Cheap Speed ratio is not constant (slip & stretch) Allows misalignment (parallel shafts) Heat accumulation Protects from overload Speed limited – 2000 m/min Absorbs noise and vibrations Power limited – 700 kW Cushion load fluctuations Endless belts needs special attention to install Needs little maintenance High efficiency (90-98%, usually 95%)
- 6. 2. Electrical fan • Electrical fans are powered by vehicle’s electrical system • More efficient alternative to mechanical fans
- 7. Advantages Disadvantages Consistent cooling Expensive Reduced water pump wear Multiple fan used for better control Multiple sizes and configurations Can fit in the radiator Have adjustable thermostat that can operate from the driver’s seat Versatility
- 8. FACTORS CONSIDERATION FOR FAN SELECTION
- 9. • Flow rate based on system requirements. Expressed as actual cubic feet per minute (acfm). • Pressure requirement based on system pressure requirements. Expressed as FSP or FTP in inches of water gauge. 1. CAPACITY • Material handled through fan. • Explosive or flammable material.2. AIR STREAM • Performance requirements • Inlet size and location • Fan weight 3.PHYSICAL LIMITATIONS
- 10. • Generated by turbulence within he fan housing. • “White” noise which is a mixture of all frequencies is mostly produced. • Radial blade fans produce a pure tone at a frequency BPF • BPF = rpm * n * CF. 4.NOISE • Safety guards are required at inlet, outlet, shaft, drive and cleanout doors. • Accessories help in future maintenance requirements. • Flow control can be done using dampers. 5. SAFETY AND ACCESSO RIES
- 11. How Cooling Fan Work? • A thermal clutch fan operates using silicon fluid as a viscous coupling medium. • When the clutch is cool and disengaged, most of the silicon fluid is stored in the reservoir allowing your fan clutch to slip relative to your water pump shaft thereby spinning at a lower RPM than the water pump.
- 12. Continue… • This saves your money because the horsepower from your engine is not wasted driving a clutch fan when it's not needed. • As your engine heats up, the thermal spring on the front of the clutch expands, which opens a valve allowing the silicon fluid to drive your clutch at an increased RPM. • This provides more air flow through your radiator, preventing your car from overheating.
- 14. INNOVATION FOR COOLING FAN SYSTEM Structure of in-fan mounted motor Built in control valve High working efficiency Wide variation in combination of pump and motor components Reversing fan rotating
- 15. CONCLUSION • A hydraulically driven engine cooling fan system is becoming more essential for lowering noises generated by construction equipment • It seems the fan system will remain as effective as ever in the future since people will further intensify attention to the issue of protecting the global environment
