A Modular Design Dual Cold Source Integrated Cold Station System

Abstract

The invention provides a modularly-designed double-cold-source integrated cooling station system. A module I is internally provided with a refrigerating device A and a heat radiating device I, and a module II is internally provided with a conveying device A, a heat radiating device II, a refrigerating device B and a conveying device B; a cold water return pipeline is connected with the water inlet end of an evaporator of a refrigerating host in the refrigerating device B through the conveying device B and is also connected with the water inlet end of a coil of a closed cooling tower in the refrigerating device A through the conveying device A; and both the water outlet end of the coil of the closed cooling tower and the water outlet end of the evaporator of the refrigerating host are connected with a cold water supply pipeline. The whole cold source system provided by the invention is modular and convenient to transport, mount and rapidly construct a cooling station; cold supply is realized by using double cold sources, and natural environmental conditions are sufficiently utilized, so that the energy efficiencies of the cold sources are increased; and the closed cooling tower can be used as a refrigerating device of a cold source I of an air conditioner and can also be used as a heat radiating device of a cold source II of the air conditioner, so that not only is the operating efficiency of the system increased, but also the utilization ratio of equipment is increased.

[0003] For a long time, central air-conditioning has been divided into several methods. One is the air-cooled chiller that does not require a cooling water system. Generally, if this method is adopted, the central air-conditioning equipment only includes refrigeration equipment and cold delivery equipment, and can be placed in The roof does not need to occupy too much building area as an air-conditioning machine room, but the cooling efficiency of this method is low; the other is a water-cooled chiller that requires a cooling water system. It is composed of cooling equipment and cold delivery equipment. This cooling method is generally more efficient than the first method, but it needs to reserve a large indoor area for placing refrigeration equipment and cold delivery equipment.

Although the two refrigeration methods have their own advantages and disadvantages, both methods have two problems: 1. It is necessary to set up a group control system for energy management and intelligent control of its cold source equipment, and generally the supplier of cold source equipment does not A complete group control system is not provided for each project, and there is often a disconnect between design and engineering construction, and the construction quality often fails to meet the design goals, and the process cannot be controlled

2. In the initial stage of air-conditioning construction, all the cooling sources in the later stage need to be designed together. The system is huge and the design is more complicated, and all related air-conditioning equipment needs to be purchased in a unified manner. Only one set of equipment may be used, but 4 sets or more need to be purchased , the initial investment is large, all equipment needs to be installed together, and the installation period is long
