Chilled water direct supply system and method

Abstract

The invention provides a chilled water direct supply system and a method. The system comprises an energy center, a thermal exchange station and at least one secondary pump; wherein the energy center is connected with the thermal exchange station by a master water supply pipe and a master return pipe. The energy source center, which is composed of at least one refrigerator and at least one primary pump, is used for preparing the chilled water; the refrigerator is in series connection with the primary pump and is arranged between the master water supply pipe and the master return pump. The thermal exchange station, which is composed of at least one draught fan and at least one triplex pump, is used for consuming cooling capacity of the chilled water; the draught fan is in series connection with the triplex pump and is arranged between the master water supply pipe and the master return pipe. The secondary pump arranged on the master water supply pipe is used for transmitting the chilled water outputted from the energy center to the thermal exchange station. The invention has the advantages of low cost and energy loss rate as well as small occupied area.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a chilled water direct supply system and a method thereof. Background technique [0002] At present, the first-stage pump system is generally used in small and medium-sized central air-conditioning projects. When the system is large, the resistance is high, and the load characteristics or resistance of each loop are very different, the secondary pump system is generally used. In the secondary pump system, water pumps are arranged on the cold and heat source side and the load side of the air-conditioning water respectively. The loop; the water pump on the load side is called the secondary pump or the secondary pump, and forms a secondary loop together with the load end equipment, the pipeline system and the bypass pipe. The primary loop is responsible for the preparation of chilled water, and the secondary loop is responsible for the delivery of chilled water. [0003] See figure 1 , ...
