wHAT IS THE DIFFERENCE BETWEEN WATER COOLED CHILLER & AIR COOLED CHILLER?
970427
The difference is big.  With a water cooled chiller, there is a unit located in the building that acts as the driving force to transfer the heat from the building water loop to a secondary loop (condenser water loop).  The second water loop is then run up to a cooling tower usually located on the roof of a building where the heat is then expelled to the atmosphere.  High efficency with these type of devices.\n\nWith an air cooled chiller, there is no secondary water loop, and the primary water loop from the building runs directly up to the roof.  There, the chiller uses the thermodynamic principles of refrigerants to directly remove the heat to the atmosphere.  There is less equipment with this system, but the efficiency is half that of the water cooled systems.\n\nAlso, air cooled chillers are limited in the total size of the cooling system that they can adaquatly handle, where as water cooled chillers can be much much larger.

the water is a very special substance. it has high specific heat capacity. meaning that water can absorb so much heat compare to other substances. for example ,water is used in cooling system of engine of a vehicle  bcoz it can absorb so much heat energy generates by the engine. humidity represent how much the water molecule in air. so the more humid the air, the cooler the air temperature the water molecules in air absorp the heat from surrounding thus making the air cooler. Get it?

An Air conditioning system normally just cools the air in the room (or vehicle) in which it is fitted.\n\nIt works like a refrigerator but expels the warm air to atmosphere rather than the room.\n\nThe disadvantage of the normal system is that it dries the air.\n\nSome systems can apply heat too so that a controlled temperature can be selected from a much wider range, and more sophisticated systems can maintain a desired humidity.

Both CPUs are using clock speeds at different frequencies.  The performance delta between the two processors is going to be due to the internals of the processor.\n\nThe processor may have internal components which need to tell the clock "wait, I'm still working on something" and then let it know when it is finished.  That 'wait' operation takes the same amount of cycles on a faster clock as it does on a slower clock.\n\nSo, the main factors (aside from the outside of heat and cooling) are the number of clock cycles consumed by internal components of the processor.  The more 'streamlined' the internal components of a processor (i.e. the less clock cycles they consume) the faster they perform an operation.\n\nYes, it is possible to have a processor that operates at lower clock speeds and performs just as fast as processors that operate at higher clock speeds, only because they found a way to solve a problem in less steps.

Wow some of these answers are scary.  The air conditioner works by taking heat from inside the room and blowing it outside.  If the air conditioner is completely in the room, then all the heat that it blows outside stays in the room, therefore the temperature stays the same.\nBut...\nAll machines create heat just by running.  Think computers, light bulbs, etc.  Therefore, the temperature will get a little higher.

its not like that , but according to HVAC data , the temp. underground is constant about 10 degrees celsius , so in summer its hot , then we find the water cooler , and in winter , the air temp. may be zero , so the water is hotter

Mist cooling is simply introducing an atomized spray of water into an airstream to cool the air.   As the water droplets vaporize and dissolve in the air, they remove heat energy from the air, leaving the air slightly cooler.\n\nThese systems are most effective in dry heat climates, where the relative humidity is low.  The water can evaporate much more quickly, removing more heat.\n\nThe lowest temperature that can be conceivably reached (provided that the system were 100% efficient) is the dewpoint temperature, also known as the wet-bulb temperature.  If the air were cooled to this temperature, its relative humidity would be 100% and it would be at maximum moisture saturation.  So, in most cases, these coolers can only reduce temperatures to 60 or 70 degrees under normal conditions, unless you're in a desert or other arid region.\n\nMost mist coolers are smaller, portable systems that use a common fan with several nozzles in front of it that produce a very fine mist spray of water.\n\nSmaller systems are also available for cooling milling work in tooling manufacturing.  These systems typically have an additive in the water supply to reduce the oxidation effects of the water.

Hot water does not freeze faster than cold, all conditions being the same, such as altitude, air pressure, and amount of cold applied to the water to make the water freeze.

The rate of cooling is directly proportional to the difference in temperature of the system with the surroundings.\nThis is why a cup of tea cools from about 70deg to 60 deg in much shorter time than it takes to cool from 40deg to 30 deg if the room temperature is constant in both cases,say 25deg.\nThis is a common life experience.

radiation\n\nbecause the above answer is correct...radiation is through AIR, not liquid\n\nconduction:  cold water cools you down, right?  conversely you heat the water\n\nconvection:  is specifically transfer of heat THRU LIQUID...so that works\n\ncondensation:  directly related to water vapor which is liquid, again

Neither. Let's have a given that 1 fridge is empty and at 40 degrees inside. The other fridge is full and at 40 degrees. The room that these 2 fridges are in is at 70 degrees. The difference in temperature is the cause for heat to flow from hot to cold. The fridges have insulation that has a certain resistance to heat flow. The heat will flow through the walls of the fridges the same, so then Q(heat flow)=A(area)x(T1(70 degrees)-T2(40 degrees))/R(resistance). The area of heat loss for both fridges are equal,the resistance of both fridges are equal, the temperature differential for both is equal,  so the amount of electricity needed to keep the fridges at 40 degrees is equal.

OK if you mean water only I assume that you require to dry out compressed air lines.  This is done by passing the air through an air drier as the air is cooled the water is separated and discharged to atmosphere or drain.  This is one method I am not sure about others.

well, ice is solid, water is liquid, and air is gas, and the potential energy increases as the stages change.  in other words, air is the warmest, water next, and ice last.  air being the warmest will warm up the ice faster and therefore melt it quicker.\n\nthe only reason that i can see why it'd be in water is if there's been a sudden change in temperature and the water is still warm but the air is cooler (cold front after a week of mid 60s or 70s weather).

No, an air conditioner will cool the room.  An air conditioner de-humidifies by passing moist warm air through a cold surface.  Water condenses and drips out.  The warm air is also cooled and sent back into the room.  The only way the air can be de-humidified is by being cooled.\n\nIf you're lucky to live in an area where you need to de-humidify in the winter, why not just buy a dehumidifier.  It will actually heat a room.

I think it's the colder the better. messed around with water cooling (quieter) for a while, haven't done any overclocking for ages though so knowledge a bit sketchy

I have a heat pump system for my shop and my wife's craft room. My shop is on the first floor and her room is on the second floor. The HVAC contractor installed one outdoor compressor and one air handler. There are electrically controlled dampers in the supply and return air from each room. There are two thermostats and a microprocessor. The microprocessor controls the dampers and directs the heating (or cooling) to which ever room is calling for it.
