[0003] However, the flammability of R32 refrigerant is significantly higher than that of R410A, and if a refrigerant leakage event occurs, excessive inhalation of R32 refrigerant will cause suffocation
Especially in the case of multi-connected systems, the total amount of refrigerant in the system is particularly large. When a refrigerant leaks

Example

[0026] The first embodiment

[0027] Please refer to figure 1 , figure 1 It is a schematic diagram of the first embodiment of the refrigeration system device provided by the present invention.

[0028] The refrigeration system device is mainly composed of compressor 1, outdoor heat exchanger 3, and indoor heat exchanger 9. This embodiment is a single-cooling, single-line refrigeration system device, that is, only one indoor heat exchanger is provided , And realize the refrigeration function separately. Among them, the compressor 1 compresses the combustible refrigerant (such as R32 refrigerant, etc.) in the refrigeration cycle into a high temperature and high pressure state, and operates in the pipeline of the refrigeration system. The indoor heat exchanger 9 functions as an evaporator during cooling operation to cool indoor air; the outdoor heat exchanger 3 functions as a condenser.

[0029] The outdoor heat exchanger 3 can also be connected with an outdoor electronic expansion va...

[0036] Second embodiment

[0037] Please refer to figure 2 , figure 2 It is a schematic diagram of the second embodiment of the refrigeration system device provided by the present invention.

[0038] In order to facilitate those skilled in the art to understand this embodiment, in this embodiment, components that have the same function and effect as the first embodiment are given the same reference numerals.

[0039] The difference between this embodiment and the first embodiment is that this embodiment is a single-line refrigeration system device that can switch between cooling and heating functions. It is mainly composed of the compressor 1, the four-way reversing valve 2, the outdoor heat exchanger 3, and the indoor heat exchanger 9. Among them, the compressor 1 compresses the combustible refrigerant (such as R32 refrigerant, etc.) in the refrigeration cycle into a high temperature and high pressure state, and operates in the pipeline of the refrigeration system. When the refr...

[0047] The third embodiment

[0048] Please refer to image 3 , image 3 It is a schematic diagram of the third embodiment of the refrigeration system device provided by the present invention.

[0049] In order to facilitate the understanding of this embodiment by those skilled in the art, in this embodiment, the same reference numerals are used for components that have the same function and effect as the above-mentioned embodiment.

[0050] The difference between this embodiment and the first embodiment is that this embodiment is a multi-line refrigeration system device that can realize a single refrigeration function. It is mainly composed of a compressor 1, an outdoor heat exchanger 3, and several indoor heat exchangers 9. That is, multiple indoor heat exchangers are installed, and they all realize the cooling function separately.

[0051] Among them, the compressor 1 compresses the combustible refrigerant (such as R32 refrigerant, etc.) in the refrigeration cycle into a high temp...

Abstract

The invention provides a refrigerating system device. The refrigerating system device comprises a compressor, an outdoor heat exchanger and at least one indoor heat exchanger, and is characterized inthat the at least one indoor heat exchanger is connected with shut-off devices and a sensor used for detecting leakage of refrigerating fluid; each shut-off device comprises a driver for sensing an electrical signal of the sensor and a shut-off valve responding to the driver to act. According to the technical scheme provided by the invention, through arrangement of the sensor for detecting leakageof the refrigerating fluid and the shut-off devices for sensing the electrical signal of the sensor to drive the shut-off valve to close a refrigerating fluid flow passage, the refrigerating system device can shut off the system flow passage in time to prevent accidents caused by leakage of a great deal of refrigerating fluid when the refrigerating system device leaks the refrigerating fluid.

Description

technical field [0001] The invention relates to an air-conditioning refrigeration system device, in particular to a refrigeration system device using flammable refrigerant. Background technique [0002] In the field of refrigeration, as the requirements for the environmental protection of refrigerants in refrigeration systems are getting higher and higher, new environmentally friendly refrigerants emerge in an endless stream, especially the performance of R32 refrigerant, R600a refrigerant, and R290 refrigerant is more prominent, such as R32 refrigerant. The greenhouse effect coefficient is only 1 / 3 of that of R410A, and the refrigerant consumption of a compressor with the same power is only 2 / 3 of that of R410A. Therefore, the application of refrigerants such as R32 in the refrigeration system is not only more environmentally friendly, but also can achieve significant economic benefits. [0003] However, the flammability of R32 refrigerant is significantly higher than that...
