Water chiller
water chiller is the amount of heat received by the first refrigerant from the second refrigerant that takes place in the evaporator (from the chiller). Changes in the cooling load on the water chiller can be caused partly because of changes: the number of occupants of the room, the occupants' activities, the use of the room, the use of electrical appliances, the outside air conditions and lighting. Components of the cooling load include: sensible heat, latent heat, outside air ventilation and other heat sources. Which includes sensible heat sources: heat transfer through buildings, solar radiation, seepage or outside air leakage, heat of lighting lamps, heat of objects of higher temperature brought into the room, occupant heat, heat from electric motors, chemical processes, or tools other electrical appliances. Latent heat sources: external air permeation with different pressures, occupant humidity, stored material moisture, wet surface moisture, chemical processes, hot water vapor etc. Whereas outside air vents can cause sensible heat due to differences in temperature and latent heat due to differences in humidity. For other sources of heat, for example air leaks from the air ducts used in the air conditioning system.
The cooling process differs significantly in the two types of coolant. The cooling absorber uses heat sources such as natural gas or steam to create a cooling effect. Chiller coolers generally use mechanical compression and are the most common. Compression chiller (compressor chiller) consists of four main components, including compressor, evaporator, condenser and valve matering system. Basically, the cooler collects heat, and then uses an evaporator heat exchanger to remove the heat.
There are two types of chiller cooling media, namely by using air and water cooling. Air condenser is cooled by using air, while water condenser is cooled by using a water source. Water coolers are generally used for cooling purposes in buildings and use cooling towers, ponds, or rivers located near buildings to release hot water from the condenser.
Air-cooled condensers operate basically the same as water-cooled refrigerants and ladder cycles along the way. The cooling medium in the condenser is of course air, not water. Air-cooled chillers are intended for outdoor installation and operation.
