DESC:FIELD
The present disclosure relates to a cooling system, in particular, it relates to a chiller for cooling a space that contains electronic equipment, such as computer server rooms and server racks in computer data centers.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art
A data center is a dedicated facility where computers, servers and electronic devices are kept. The data center has a controlled environment where dust, humidity and ambient temperature are monitored closely. These electronic devices require electricity for their operation. During the operation of these electronic components, a portion of the electrical energy is converted to heat due to the electrical resistance of the circuitry. The overheating results in the failure of electronic components.
Generally, a chiller is used for cooling the interior spaces of data centers. The chiller removes the heat generated by the electronic devices so that electronic devices function correctly and avoid failures of components.
However, the conventional chillers do not provide any access to the interior space of the chiller. Hence repair, and maintenance of inner components of the chiller becomes a cumbersome task.
For cooling industrial plants and large data centers, large-sized chillers are used. These chillers have a large footprint and hence require bigger space for installation. These conventionally used chillers cannot be readily installed like a plug-and-play type of device.
Further, a large-sized chiller comprises a large condenser which consumes a large amount of electricity. Also, conventional chillers do not have an aesthetic view.
Furthermore, the conventional chillers includes one or more compressors of predefined capacity. Therefore, during operation, all the compressors are required to function, there is no option available in the conventional chiller to selectively operate any one of the compressors as per the cooling load requirement and thus, the conventional chillers possess high redundancy.
Therefore, there is a need for a chiller that eliminates the aforementioned drawbacks.

Generally, a chiller is used for cooling the interior spaces of data centers. The chiller removes the heat generated by the electronic devices so that electronic devices function correctly and avoid failures of components. However, the conventional chillers do not provide any access to the interior space of the chiller. Hence repair, and maintenance of inner components of the chiller becomes a cumbersome task.
Further, for cooling the industrial plants and large data centers, large-sized chillers are used. These conventional chillers have a large footprint which increases the maintenance requirement, overall cost and power consumption of the system.

EXAMPLE
In an exemplary embodiment, In an operative configuration of the chiller 100, the evaporating unit 134 is configured to be in communication with a heat exchanging means of a datacenter or a space required to cool. The data center is provided with a water type cooling arrangement. Therefore, the water circulates within the datacenter across the plurality of conduits. The plurality of conduits is configured to be in communication with an air handling unit (AHU) 144. The inlet and the outlet conduit of the datacenter is in fluid communication with the additional inlet and outlet of the evaporating means.
