摘要：Work together more cooling source (refrigeration machines) the system of centralized supply cooling energy ( SCSCE ) is a way to achieve cost-effective operation and safe and rational supply consumption area with cool water for central cooling and air conditioning . Maximum energy needs cold water occurs rarely ,because the extremely high temperatures occur rarely . Therefore ,the total cooling load is divided into basic and peak . One of the main characteristics that define the justification of the use of coupled processes and sizes hourly coefficient centralized supply of cold water,temperature regime , or hour coefficient district cooling . Determination of Optimal hour coefficient district cooling is one of the most techno economic tasks at the design of the system of centralized supply cold water for air conditioning and industrial building social housing and business districts .
