Description

Technical Field

[0001] The utility model belongs to the technical field of central air-conditioning, in particular to a cold source circulation device for a central air-conditioning. Background Art

[0002] A central air conditioning system consists of one or more cooling and heat source systems and multiple air conditioning systems. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment. The refrigeration system is a crucial component of the central air conditioning system. Its type, operating mode, and structural form directly affect the economic efficiency, efficiency, and rationality of the central air conditioning system during operation. In the central air conditioning system, circulating cooling water is used to cool the air-conditioned rooms. After the cooling water completes the heat exchange with the air conditioning refrigeration equipment, the high-speed hot water is sent to the cooling tower through water pipes. After the heat is dissipated in the cooling tower, it is returned to the refrigeration equipment through the outlet pipe for circulation.

[0003] In comparison, the Chinese patent with announcement number CN217503829U discloses a cooling water circulation device for a central air conditioner, including a cooling box, a filter box fixedly connected to the top of the cooling box, a filter plate slidably inserted between two U-shaped frames, and connecting pipes are connected to the bottoms of both sides of the filter box below the filter plate. The end of the connecting pipe away from the filter box extends into the cooling box and is fixedly connected to a water spray pipe. A cooling plate is fixedly connected to the cooling box between the two water spray pipes, and a plurality of water spray heads are evenly connected to the water spray pipe on one side of the cooling plate; it also includes a heat dissipation mechanism for dissipating heat from the cooling plate and a connecting mechanism connecting the connecting plate and the filter box.

[0004] However, the above patent uses air circulation and heat dissipation plates to cool down, which still cannot effectively prevent water evaporation and loss. The heat dissipation cost is relatively high, and the frequent contact of cooling water with air causes the antifreeze and anti-corrosion agents in the cooling water to volatilize, affecting the refrigeration effect. Therefore, a new device needs to be designed. Utility Model Content
