Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioners, and more specifically, to a central air conditioner with air volume matching space. Background Art

[0002] Central air conditioning consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment; central air conditioning has the advantage that the air volume can match the size of the installation space.

[0003] For example, a central air conditioner disclosed in CN207962979U has the following technical solutions: it includes a surface cooler, which is used to reduce the moisture content in the air; a heating section, which is located at the rear of the surface cooler and connected to the surface cooler; a humidifying section, which is located at the rear of the heating section and connected to the humidifying section, and is used to increase the humidity in the air to a set value; an outdoor air inlet pipe, one end of which is connected to the surface cooler and the other end is arranged outdoors; an indoor return air pipe, one end of which can be connected to the room and draw the indoor air out, and the other end is also provided with a first branch pipe and a second branch pipe, the first branch pipe is connected to the surface cooler, and the second branch pipe is connected to the heating section; an air supply pipe, the One end of the air supply pipe is connected to the humidifying section, and the other end can be connected to the indoor room; it is mainly achieved by extending a first branch pipe and a second branch pipe to the indoor return air duct, the first branch pipe is connected to the surface cooler, and the second branch pipe is connected to the heating section, so that a part of the air drawn out from the indoor room does not pass through the surface cooler, thereby reducing the pressure of the surface cooler. Since the indoor air itself is at a temperature and humidity standard, the new outdoor air is surface cooled to reduce the humidity, and then mixed with the indoor air and passed through the heating section and the humidifying section to reach the specified humidity and temperature. Therefore, when the outdoor humidity is high, it can ensure that the indoor humidity will not change significantly, reducing the working pressure of the surface cooler, thereby better controlling the indoor temperature and humidity.

[0004] The above-mentioned central air conditioner with air volume matching space still has certain shortcomings: after long-term use, dust will adhere to the surface of the central air conditioner outlet mesh. Once the dust blocks the outlet mesh, it will affect the air volume of the central air conditioner, and then affect the use of the central air conditioner. Therefore, it is necessary to provide a central air conditioner with air volume matching space. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a central air conditioner with air volume matching space to solve the problems existing in the prior art.

[0007] Wherein, the material of the fastening frame is a rubber component, and the cross-sectional area of ​​the fastening frame is smaller than the cross-sectional area of ​​the connecting shell.

[0008] The anti-damage component includes a protective protrusion and a first mounting disc, and two first mounting discs are detachably mounted at the bottom end of the side wall of the protective protrusion symmetrically along the center.

[0009] A limiting telescopic rod is fixedly installed at the center of the side wall of the first mounting disc, a force relief spring is fixedly sleeved on the outer surface of the limiting telescopic rod, and the extended length of the limiting telescopic rod is smaller than the extended length of the force relief spring.

[0010] Wherein, a second mounting disc is fixedly mounted on one end of the decompression spring, and a side wall of the second mounting disc is connected to one side of the outer surface of the connecting shell.

[0011] The material of the protective bump is a rubber component, the edges and corners of the protective bump are rounded, the number of the protective bumps is several, and the several protective bumps are equally divided into two groups.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. In the above scheme, the central air conditioner is provided with a hydraulic lifting rod, a mounting frame and a fastening frame. When the air outlet mesh is blocked by dust, the hydraulic lifting rod is first started to drive the mounting frame to move downward. After moving to a certain distance, the blocked air outlet mesh is pressed downward. At this time, the air outlet mesh is taken out from the inside of the fastening frame, and then the blocked air outlet mesh is cleaned, so that the normal operation of the central air conditioner can be ensured. Because the hydraulic lifting rod has the function of automatic lifting, and the air outlet mesh is clamped inside the fastening frame, it is easy to clean the blocked air outlet mesh, thereby enhancing the practicality of the device;

When the staff is repairing the central air conditioner and is about to come into contact with the corners of the connecting shell, the anti-damage component arranged at the corners of the connecting shell will work, and the protective protrusion will contact the staff instead of the connecting shell, and the protective protrusion will transfer the force received during the contact to the two sets of limiting telescopic rods and the force release spring. When external force acts on the force release spring, the force release spring will release the external force according to its own performance, thereby reducing the reaction force received by the staff when in contact. In addition, the corners of the protective protrusion are rounded, so it can be ensured that the staff will not be injured, so that there is no safety hazard in the device.
