Basically the principle of water cooled chiller as the cooling systems such as air conditioning which consists of several main components, namely evaporator, condenser, compressor and expansion device. In the evaporator and condenser heat exchange takes place. In the water cooled chiller water contained as secondary refrigerant to take heat from the material being cooled to the evaporator. This water will experience temperature changes when heat absorbed and released in the evaporator.
In general working principle is as follows. Refrigerant is compressed in the compressor and then flows into the condenser. Refrigerant that flows into the condenser has a high pressure and temperature. Refrigerant in the condenser is cooled by outside air around the condenser so that the phase change from vapor to liquid. Then, the refrigerant flows into the capillary tube and a decrease in pressure.
Once out of the capillary tube, the refrigerant into the evaporator. In the evaporator the refrigerant begins to evaporate, this was due to a decrease in pressure that resulted in the boiling point of refrigerant to be lower so
refrigerant evaporates. In the evaporator refrigerant changes phase from liquid to vapor. In the evaporator heat transfer which occurs a low temperature, where the water is cooled by a refrigerant. Then the refrigerant in the vapor are supplied to the compressor again.
In the evaporator, water as a secondary coolant which has been cooled to a certain temperature and then drained by a pump to the cooling coils in the room. This water will circulate continuously for system
In a refrigeration system, refrigerant is ideal minimal following properties:
A. Evaporation of positive pressure
Positive pressure to prevent evaporation of the possibility of leakage of air into the system during during the operation.
2. Freezing pressure is quite low.
3. Freezing temperature must be low enough,
Refrigerant so that compaction does not occur during normal operation.
4. Lubricating oil solubility
Oils used as lubricants in the refrigerator, especially on the system, should be easy to dissolve, because it contact with refrigerant.
5. Refrigerant is low.
6. Not combustible.
Refrigerant vapor can not burn or fire resulting in any concentration with air.
7. Have condensation pressure is not too high,
Due to the high condensation pressure compressor requires a large and powerful, as well as the pipes have to be strong and the possibility of very large leaks.
8. High dielectric strength.
This trait is important for hermetic compressor, because the refrigerant vapor is directly related to the motor.
9. Has a stable chemical structure,
should not be unraveled each time compressed, condensed, and evaporated.
The market for electric cars or hybrid is still at an early stage of dynamic growth and growth in the U.S.. Some people are not willing to make drastic changes to switch to electric cars, but still want to contribute to environmental awareness. A great alternative to passing vehicles is fully self some of the features which in turn will help save a lot of energy, money, ass, and emissions work. New features also influence the green car insurance quote rate and the cost of insurance or, depending on your provider. However, it is never a bad idea to keep your car as up to date with new green technologies, which is a great investment.
Newly developed four-cylinder engine and transmission ECO Gear is a great feature for upgrading. These engines are fitted with an optional three horses – 95, 129 and 163 hp. Pulling force has a great power, great traction – you can choose between 184, 225, or 265 lb-ft of torque. In ECO Gear six-speed manual, there are very low first gear with a maximum energy savings potential of an overdrive sixth gear, which helps to stabilize a low motor speeds.
Another important feature is the energy-saving ECO start / stop ignition starter. This start / stop function is so useful and handy, especially in commercial vehicles. Less energy is a start / stop function of the engine because the engine starts immediately when the brake is pressed or press the clutch pedal. This start / stop ignition also gives you better coverage because it takes less energy and fuel to start your car.
