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.
Dear readers,on this global world ,people love to do anything through the internet such as buying everything online,getting an information through website so the contribution of website is really bizarre,just like what website design austin does,they are making a good quality website without leaving their duty to promote their customer’s products through the web they making.
Dear readers,the new internet model has additionally ushered within the age of online videos, wherever sites like Google videos and YouTube cater to the common human part to create one’s voice detected, in addition on peer into the lives and experiences of others. On-line videos will combat varied forms reckoning on their content.Porn videos are personal on-line videos that involve a personal or teams of individuals reproval a camera and secret writing eventsdocumenting experiences through a number of video selections. alternative blogs can involve capturing experiences, the same as a diary vogue for others to look at . Some blogs can involve posting photos, along side captions still within the kind of a diary for others to look at on-line.
Trailers or previews of up and returning picture shows have long been on the market online for avid movie watchers to ascertain once more and once more. Administrators and producers have taken this a step any by making net promotional blogs, wherever administrators relay their stepchild the net or gift scenes for picture show watchers to look at and decide.
It is often arduous to invariably watch your favorite news programs or shows if you’re busy at the workplace and come late at nighttime. Some TV production corporations have currently come back up with streaming video, which may permit you to catch up with the shows on-line.
Streaming video includes news segments of a show, or the show itself endure your net browser or media player. Streaming video works best with quick net connections, as net traffic will usually interfere with the standard of video playback.Well,as effect from many sites that you encounter in internet then you could use new feature which is Porno Twitter ,porn that you could see from social media such Twitter,for more porn videos you might see if you visit twitter.com/porn.
Dear my readers,looking for the new vehicle perhaps is everybody’s dream but not everybody afford to buy that,that’s why people start looking for the second hand vehicles.For those of you who looking for the second hand cars please visit vehicles for sale at your nearest car dealers or you could try get the related information by browsing through the internet.Good luck
