Fig. 7 is a schematic diagram of an air conditioner according to an embodiment of the present application. As shown in fig. 7, the air conditioner is an indoor unit of a multi-connected air conditioner (i.e., a multi-connected ceiling unit), and includes a casing 020, components that implement air conditioning functions, such as a heat exchange component (not shown in the figure) and a fan (not shown in the figure), are disposed in the casing 020, and an expansion valve component 010 is disposed outside the casing 020. In this embodiment, the mounting portion 117 of the case 110 of the expansion valve 200 is attached to the surface of the casing 020, and is connected to the casing 020 by a fastening member, thereby fixing the expansion valve assembly 010.
In summary, the expansion valve mounting case 100 according to the embodiment of the present invention is used to accommodate the expansion valve 200, and two insulating cottons 130 are used to clamp the expansion valve 200. When the expansion valve 200 is installed in the expansion valve installation box 100, due to the isolation effect of the expansion valve installation box 100 and the sound absorption effect of the heat insulation cotton 130, the volume of noise generated by the noise transmitted out of the expansion valve installation box 100 is small, and the heat insulation cotton 130 has a damping effect, so that the noise generated by the vibration of the expansion valve 200 can be reduced, and meanwhile, the expansion valve 200 is protected. In addition, because the expansion valve 200 is clamped by the heat insulation cotton 130, condensation cannot be generated outside the expansion valve 200; the heat insulation effect of the heat insulation cotton 130 is good, so that the temperature of the outer side of the expansion valve mounting box 100 can be close to the ambient temperature, and condensation is not easy to generate; meanwhile, the state of the refrigerant in the expansion valve 200 is not easily influenced by the environment, and the good operation of the air conditioner is ensured.
