Chilled Water Air Conditioning Principles And ApplicationsHow Chilled Water Air Conditioning Works. Chiller. The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. The water leaves the chilled water evaporator at 45°F or 7°C. This chilled-water is then circulated through the entire building by the use of a pump.
Comparison of DX and Chilled Water Central Air Conditioning ...The Direct Expansion (DX) and Chilled Water central air conditioning plants are both used at different places depending on the applications and size of the place to be air conditioned. Both of them have their own advantages and disadvantages. Let us see the comparison of DX and chilled water central air conditioning plants.

How air conditioning works - conservationphysics.orgHow air conditioning works The essential ingredients in an air conditioning system are a fan to blow air around, a cold surface to cool and dehumidify the air, a warm surface and a source of water vapour. In a large system there will also be a tangle of tubes to distribute the air and collect it again.
DC Inverter Air Conditioner Working PrinciplesIn recent years, DC inverter air conditioner is becoming more popular compared to the conventional air conditioner due to its many advantages. As the compressor takes the most power in any air conditioning system, the change in the compressor technology has enabled better and more efficient air conditioner or heatpump to be deployed.

Chilled water - WikipediaChilled water is a commodity often used to cool a building's air and equipment, especially in situations where many individual rooms must be controlled separately, such as a hotel. The chilled water can be supplied by a vendor, such as a public utility or created at the location of the building that will use it, which has been the norm.
Centralized Vs Decentralized Air Conditioning Systems• Central air conditioning systems serve multiple spaces from one base location. These typically use chilled water as a cooling medium and use extensive ductwork for air distribution. • Decentralized air conditioning systems typically serve a single or small spaces from a location within or directly adjacent to the space. These are essentially
