Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to a novel compound evaporative condenser. Background Art

[0002] In the refrigeration system, the evaporator, condenser, compressor and throttle valve are the four essential components of the refrigeration system. Among them, the evaporator is a device for conveying cold, and the compressor plays the role of sucking, compressing and conveying refrigerant vapor; the condenser is a device that releases heat, and transfers the heat absorbed in the evaporator together with the heat converted by the compressor to the cooling medium; the throttle valve plays a throttling and pressure-reducing role on the refrigerant, and at the same time controls and adjusts the amount of refrigerant liquid flowing into the evaporator, and divides the system into two parts: the high-pressure side and the low-pressure side; and the refrigerant circulates in the system composed of the four major components, undergoes state changes, and exchanges heat with the outside world.

[0003] In the specific refrigeration cycle process, after the liquid refrigerant absorbs the heat of the cooled object in the evaporator, it vaporizes into high-temperature, low-pressure steam, is sucked into the compressor, compressed into high-pressure, high-temperature steam, and then discharged into the condenser, where it releases heat to the cooling medium (water or air), condenses into high-pressure liquid, is throttled by the throttle valve to low-pressure, low-temperature refrigerant, and enters the evaporator again to absorb heat and vaporize, thereby achieving the purpose of cyclic refrigeration.

[0004] Specifically speaking, the condenser is a component of the refrigeration system and is essentially a heat exchanger. Its specific function is to absorb heat through water cooling or air cooling and convert high-temperature gaseous refrigerant into low-temperature liquid refrigerant.

[0005] Condensers can be divided into air-cooled condensers, water-cooled condensers, evaporative condensers and spray condensers according to different cooling methods. The selection of condenser form and model takes into account the local water source, water temperature, climatic conditions, the total cooling capacity of the refrigeration system and the layout requirements of the refrigeration room, and determines the flow and resistance of cooling water or air flowing through the condenser.

[0006] As mentioned above, although there are many types of condensers, since most condensers have certain special features, they generally have the following problems when used in various cooling scenarios: 1. The cooling method is limited, resulting in a single cooling function.

[0007] 2. The cooling thread is short and the cooling effect is poor. Specifically, the length of the thread in which the coolant flows in the pipeline will directly affect the degree of heat release of the coolant. If the thread is too short, the gaseous coolant cannot be completely condensed into liquid coolant, so that the expected cooling effect cannot be achieved; if the thread is too long, the coolant will stay in the pipeline for a longer time and reduce the cooling efficiency.

[0008] 3. The recycling rate of spray water is low.

[0009] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
