context_page_description: Temperature chaining can mean temperature, thermal or energy chaining or cascading.
  Temperature chaining has been introduced as a new concept at Datacentre Transformation in Manchester by the company Asperitas as part of a vision on a Datacentre of the Future. It is a method of transforming electrical consumption in datacentres into usable heat. The concept is based on creating high temperature differences in a water based cooling circuit in a datacentre. The premise is that every system in a datacentre can be equipped with a shared water infrastructure which is divided into multiple stages with different temperatures. The different temperatures are achieved by setting up different liquid cooling technologies with different temperature tolerances in a serial cooling setup as opposed to a single parallel circuit. This creates high temperature differences with a low water volume. This results in a datacentre environment which is capable of supplying constant temperature water to a re-user, thus transforming the facility from an electrical energy consumer into a thermal energy producer.
context_section_description: In smaller footprints, temperature chaining can be achieved by creating a small water circuit with a mixing valve and buffer tank. This allows the output of the liquid installation to be routed back to the cooling input to gradually increase the cooling circuit and achieve a constant high output temperature. Although this is not the multi-stage approach, it is a common and well proven practice for achieving constant input or output temperatures.
  The advantage of this approach is the compatibility with variable input temperatures which are common with dry cooling installations.
