Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning connecting pipe used in a low-temperature environment. Background Art

[0002] Air conditioning, also known as air conditioners, refers to equipment that manually regulates and controls parameters such as temperature, humidity, cleanliness, and flow rate within a building or structure. It typically consists of several components: a cooling / heating source, a cold / hot medium distribution system, a terminal unit, and other auxiliary equipment. These primarily include a refrigeration unit, a water pump, a fan, and a piping system. The terminal unit utilizes the distributed cold and heat to process the air, ensuring that the desired air parameters are met. Air conditioners typically consist of an indoor unit and an outdoor unit, connected by an insulated connecting pipe for refrigerant transport.

[0003] With the development of the times, air conditioners are becoming more and more popular. However, for users in the north, facing the severe cold in winter, the air conditioners often cannot adapt to the cold weather and cannot work. The main problem is that the connecting pipes between the indoor and outdoor units of the air conditioner are affected by the low temperature environment, causing heat loss, which in turn affects the heat transfer efficiency of the air conditioner. Therefore, it is necessary to develop an air conditioner connecting pipe that can be used in low temperature environments.

[0004] A Chinese utility model patent with authorization announcement number CN 204729840 U has been found to disclose an air conditioning insulation pipe, comprising an air conditioning pipe and at least two insulation sleeves, wherein the at least two insulation sleeves are sleeved onto the outer surface of the air conditioning pipe, and the end faces of the insulation sleeves are provided with a traceless adhesive layer, through which two adjacent insulation sleeves are bonded. The air conditioning insulation pipe of the utility model can be used by cutting a long insulation sleeve formed in one step into two or more shorter insulation sleeves. During production and assembly, each insulation sleeve can be sequentially sleeved onto the outer surface of the air conditioning pipe. Since the insulation sleeves are relatively short, they are easier to sleeve onto the outer surface of the air conditioning pipe, which facilitates assembly and improves production efficiency. In addition, the traceless adhesive layer is used to bond the two adjacent insulation sleeves together. The traceless adhesive layer has strong adhesion and is not easy to harden, which can ensure that the connection between the two adjacent insulation sleeves is well sealed and will not crack during long-term use, thereby making the air conditioning insulation pipe have a better insulation effect.

[0005] However, the above device still has the following technical problems:

[0006] 1. The two adjacent insulation sleeves are bonded together with a traceless adhesive layer. Although the traceless adhesive layer has strong adhesion and is not easy to harden, the gap between the connections still has the defect of easy heat dissipation. Especially in the cold winter in the north, the inside of the pipe is hot and the air outside the insulation sleeve is cold. Heat can easily be lost through the connection of the insulation sleeve, thereby affecting the heat transfer efficiency.

[0007] 2. Another embodiment of the insulation pipe connection method is that a boss is provided at one end of the insulation sleeve, and a groove matching the boss is provided at the other end of the insulation sleeve 2. The bosses and grooves of adjacent insulation sleeves are connected by interference fit. We know that the interference fit method requires a lot of force to achieve, and the above device is not installed with auxiliary components suitable for the user to exert force, so there is a problem of inconvenience in installation.

[0008] Based on the above technical problems, it is very necessary to provide an air-conditioning connecting pipe that is easy to install, has good thermal insulation effect and can be used in low-temperature environments. Utility Model Content

[0009] The utility model aims at the deficiencies of the prior art and provides an air-conditioning connecting pipe used in a low-temperature environment, thereby effectively solving the problems raised in the background art.

[0010] In order to solve the above problems, the technical solution adopted by the utility model is: an air-conditioning connecting pipe used in a low-temperature environment, including an air-conditioning pipe, and also including at least two insulation sleeves sleeved on the outside of the air-conditioning pipe, the insulation sleeves are connected by a connecting unit, the connecting unit includes a first connecting member and a second connecting member, the first connecting member and the second connecting member are threadedly connected to the insulation sleeve through a connecting head, and the interior of the first connecting member and the second connecting member are provided with a through groove penetrated by the air-conditioning pipe.

[0011] Preferably, a heat-insulating cavity is provided in the wall of the heat-insulating sleeve, and the heat-insulating cavity is filled with heat-insulating material.

[0012] Preferably, a heat-insulating cavity is provided inside the first connecting member and the second connecting member, and the heat-insulating cavity is filled with heat-insulating material.

[0015] Preferably, the second connecting member is plugged into the stepped groove of the first connecting member through a connecting pipe, and the outer surfaces of the first connecting member and the second connecting member are fixed with matching flanges, and the two flanges are fixed in position by bolts.

[0016] The utility model has novel structure, ingenious design, simple and convenient operation, and has the following advantages compared with the existing technology:

[0017] 1. By providing the first connecting piece and the second connecting piece, not only is the installation of the user facilitated, but also the heat loss from the connection of the thermal insulation sleeve is further avoided, the heat utilization rate is improved, and the practicality of the device is increased.

[0018] 2.
