Description

Technical Field

[0001] This utility model relates to the field of heat exchange, and in particular to a fluorine-free refrigeration heat exchange device. Background Technology

[0002] Fluorinated refrigerants (such as Freon) are widely used in refrigeration and heat exchange systems. However, fluorinated refrigerants damage the ozone layer and may contribute to global warming. With increasing environmental awareness and increasingly stringent international environmental regulations, finding and developing fluorine-free alternatives has become an important issue in the field of refrigeration and heat exchange.

[0003] Currently, in the field of fluorine-free refrigeration and heat exchange, common technologies include using natural working fluids (such as carbon dioxide, ammonia, propane, etc.) and synthetic working fluids (such as R134a, R410A, etc.) as refrigerants.

[0004] Carbon dioxide refrigeration technology is environmentally friendly and efficient, but it requires operation under high pressure and places high demands on system sealing and safety. Ammonia, as a refrigerant, has good thermodynamic properties, but it is toxic and flammable, requiring strict safety measures during its use. Synthetic working fluids such as R134a are relatively stable, but their global warming potential is still not zero, and they still have some impact on the environment.

[0005] The damage to the ozone layer and the exacerbation of the greenhouse effect caused by traditional fluorinated refrigerants are global environmental problems. The emergence of fluorine-free refrigeration and heat exchange technology has fundamentally solved the environmental hazards of refrigerants and helped protect the Earth's ecological balance and atmospheric environment.

[0006] Secondly, in terms of heat exchange efficiency, it is necessary to address the problem of relatively insufficient heat exchange performance of fluorine-free refrigerants under specific operating conditions. This can be achieved by optimizing the structural design of the heat exchanger and improving the refrigeration cycle system to enhance the overall heat exchange efficiency and meet the refrigeration needs in practical applications. Utility Model Content

[0007] The main objective of this invention is to provide a fluorine-free refrigeration and heat exchange device.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A fluorine-free refrigeration heat exchange device includes a heat exchange device, a heat exchange fan, an insulated heat exchange device, a cold storage replacement module, and a water pump circulation device. The input end of the heat exchange device is connected to the insulated heat exchange device, and the output end of the heat exchange device is connected to the water pump circulation device. The output end of the water pump circulation device is connected to the insulated heat exchange device. The insulated heat exchange device contains a cold storage replacement module, and the output and input ends of the cold storage replacement module are provided with external quick-connect connectors. A heat exchange fan is provided on one side of the heat exchange device, and the exhaust end of the heat exchange fan faces the heat exchange device.

[0010] Furthermore, a temperature sensor is provided between the water pump circulation device and the heat exchange device. The temperature sensor signal transmission is connected to the water pump power control device, which is electrically connected to the water pump circulation device.

[0011] Furthermore, the heat exchange device includes a main frame, an insulation box, and heat exchange pipelines. The insulation box is fixedly installed on the main frame. An embedding groove is provided inside the insulation box. The heat exchange pipelines are provided inside the insulation box. The heat exchange pipelines pass through the cold storage replacement module repeatedly. The cold storage replacement module is embedded in the embedding groove.

[0012] Furthermore, the cold storage replacement module includes one or more cold storage boxes, which are placed between insulated boxes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model performs the first heat exchange of the cooling medium through a cold storage replacement module and a heat exchange device. The cold storage replacement module contains normal water. Through the first heat exchange, it absorbs the heat in the cooling medium, thereby turning the normal cold water into warm water and realizing heat recovery.

[0015] The cooling medium undergoes a second heat exchange through the cooperation of a heat exchange device and a heat exchange fan, thus completing the cooling process. The first heat exchange reduces the load on the second heat exchange and improves the cooling effect of the cooling medium. Attached Figure Description
