Abstract
Description
- The subject matter herein generally relates to refrigeration equipment, and more particularly to a noise reduction device in refrigeration equipment.
- Generally, refrigeration equipment such as a refrigerator uses refrigerant liquid. The refrigerant liquid is cycled between a gaseous phase and a liquid phase. The refrigerant liquid may produce noise during transition between the gaseous phase and the liquid phase.
- Implementations of the present disclosure will now be described, by way of embodiments only, with reference to the attached figures.
-
FIG. 1 is a diagram of a cycle of refrigerant liquid in refrigeration equipment in accordance with an embodiment of the present disclosure. -
FIG. 2 is a diagram of a first embodiment of a structure of a noise reduction device of the refrigeration equipment inFIG. 1 . -
FIG. 3 is similar toFIG. 2 showing the first embodiment of the structure of the noise reduction device. -
FIG. 4 is a diagram of a second embodiment of a structure of a noise reduction device inFIG. 1 . - It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
- Several definitions that apply throughout this disclosure will now be presented.
- The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.

FIG. 1 shows an embodiment of refrigeration equipment 100 including acompressor 11, acondenser 12, adry filter 13, acapillary 14, anoise reduction device 15, and anevaporator 16. Air having a low temperature and low pressure flows into thecompressor 11. Thecompressor 11 compresses the air, and the compressed air has a high temperature and high pressure. The compressed air flows from thecompressor 11 to thecondenser 12 to be cooled. The air cooled by thecondenser 12 has a low temperature and a high pressure. The cooled air having a low temperature and a high pressure flows through thedry filter 13 into thecapillary 14. The air flowed into the capillary is condensed into a refrigerant liquid having a low temperature and low pressure. The refrigerant liquid is passed from thecapillary 14 to theevaporator 16 through thenoise reduction device 15. The refrigerant liquid flowing into theevaporator 16 is evaporated into air having a low temperature and low pressure. The air having a low temperature and low pressure is once again passed through thecompressor 11, and the cycle continues as described above. - The
noise reduction device 15 includes at least one transition tube through which the refrigerant liquid flows from thecapillary 14 to theevaporator 16. A diameter of the at least one transition tube gradually increases from thecapillary 14 to theevaporator 16. The gradually increasing diameter of the transition tube reduces a speed of flow of the refrigerant liquid from thecapillary 14 to theevaporator 16, thereby preventing a sputtering noise caused by a speed of flow of the refrigerant liquid being too fast from thecapillary 14 to theevaporator 16. Referring toFIG. 2 , thenoise reduction device 15 further includes adamping adhesive 154 for further reducing noise of the refrigerant liquid during a transition from thecapillary 14 to theevaporator 16. It should be understood that the refrigeration equipment 100 further includes a fan, a humidity control system, a housing, and other components which will not be discussed herein. -
