Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a centralized cooling equipment with efficient heat exchange. Background Technique

[0002] The commonly adopted design scheme for the centralized refrigeration and heating system of thermal power plants is that the control building or the electronic equipment room adopts a centralized cooling and ventilation design with a water-cooled screw chiller or an air-cooled heat pump as the core, and each office, distribution room, and auxiliary workshop adopts a split air-cooled heat pump air conditioner to adjust the indoor temperature. The currently used centralized refrigeration and heating unit is connected to the steam turbine through the steam turbine circulating water supply valve and the steam turbine circulating water return valve, and is used to produce cold water and hot water. When the circulating pump is turned on, it is used by the air handling unit for the end users. The centralized refrigeration and heating unit is also connected to the valve for circulating water to return to the cooling tower. When the valve for circulating water to return to the cooling tower is opened, the circulating water is transported to the cooling tower for cooling.

[0003] The utility model patent with the authorization announcement number CN219955437U discloses a device for centralized heating and cooling. The utility model includes a pipeline, an installation groove is opened inside the pipeline, an installation piece is arranged inside the installation groove, a left fixing piece is fixedly connected to the outside of the installation piece, a copper pipe is arranged inside the left fixing piece, a one-way valve is installed inside the copper pipe, a right fixing piece is arranged outside the left fixing piece, a fixing bolt is arranged inside the right fixing piece, a sealing ring is fixedly connected to the outside of the pipeline, and a fixing ring is fixedly connected to the tail end of the sealing ring. This device for centralized heating and cooling has the function of pre-cooling before condensation. The copper pipe is used to access the cold substance to pre-cool the hot substance inside the pipeline, so that the hot and humid substance exchanges heat with the cold and dry substance, and the temperature of a part of the hot and humid substance is reduced in advance, which can effectively reduce the load of the condensation equipment and solve the problem of the lack of pre-cooling structure in the current centralized heating and cooling equipment.

[0004] Although the above-mentioned utility model sets a pre-cooling structure in front of the heating and cooling equipment to prevent high-temperature gas from directly entering the heating and cooling equipment, the above-mentioned utility model only exchanges heat through a single copper pipe. The contact area between the single copper pipe and the high-temperature gas is small, and the placement position of the copper pipe is relatively off, so it cannot contact most of the hot air inside the pipeline, resulting in low heat exchange efficiency. In view of this, we propose a centralized cooling equipment with efficient heat exchange. Content of the Utility Model
