In other words, both widthwise opposite sides of the panel 120 extend beyond both widthwise opposite side surfaces of the case 110, so that both widthwise sides of the bottom surface of the case 110 are covered with the panel 120, and also both lengthwise sides of the case bottom surface 110 may extend beyond both lengthwise opposite side surfaces of the case 110. The panel 120 can completely cover the box body 110, and the bottom surface of the box body 110 is covered by the panel 120, so that the aesthetic property of the ceiling air conditioner 1 is improved on one hand, and the bottom of the box body 110 is fixed with the ceiling through being installed with the panel 120 on the other hand. Because the relative both sides of the width direction of panel 120 all exceed box 110, make panel 120 and furred ceiling connection area great, panel 120 installs with furred ceiling and box 110 respectively, has further guaranteed the assembly fastness of smallpox machine air conditioner 1.

The distance that the panel 120 exceeds the side of the case 110 where the second return air opening 102 is located is greater than the distance that the panel 120 exceeds the side of the case 110 opposite to the second return air opening 102. The first return air inlet can have a larger area at the portion beyond the side of the machine body 100, so as to increase the flow rate of the air flowing to the second return air inlet 102, and improve the return air effect of the ceiling air conditioner 1.

In some embodiments of the present invention, as shown in fig. 6, the width of the first air return opening 101 is greater than the width of the second air return opening 102, and the length of the first air return opening 101 and the length of the second air return opening 102 are not less than the length of the heat exchanger 200.

The width of the first air return opening 101 is larger, two parts of the first air return opening 101 exceeding the side surface of the box body 110 and not exceeding the side surface of the box body 110 are formed along the width direction of the first air return opening 101, the part of the first air return opening 101 exceeding the side surface of the box body 110 is communicated to the outer side of the second air return opening 102, and the part of the first air return opening 101 not exceeding the side surface of the box body 110 is communicated to the inside of the box body 110. Through setting up the great first return air inlet 101 of width, guarantee the airflow that directly transports in to box 110 and the airflow that transports to second return air inlet 102, make the area of first return air inlet 101 and second return air inlet 102 more reasonable.

In some embodiments of the present invention, as shown in fig. 7, the width of the panel 120 is not less than 480mm, the width of the box 110 is not more than 380mm, and the distance that the first air return opening 101 exceeds the side surface of the box 110 is greater than or equal to 55mm and less than or equal to 65 mm.

The distance d1 that first return air inlet 101 surpasses the side of box 110 is more than or equal to 55mm and is less than or equal to 65mm, and the width size of panel 120 is comparatively reasonable, both can make the part that first return air inlet 101 surpasss box 110 have great gas flow area to guarantee that the return air volume to second return air inlet 102 is great, panel 120 can not occupy too big space again simultaneously, makes things convenient for smallpox machine air conditioner 1's installation.

Other configurations and operations of the ceiling-based air conditioner 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.

The utility model discloses well smallpox machine air conditioner carries out smallpox machine air conditioner's refrigeration cycle through using compressor, condenser, expansion valve and evaporimeter. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. Ceiling air conditioners can regulate the temperature of an indoor space throughout a cycle.

The outdoor unit of the ceiling-mounted air conditioner refers to a portion of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the ceiling-mounted air conditioner includes the indoor heat exchanger, and the expansion valve may be provided in either the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The ceiling air conditioner serves as a heater in a heating mode when the indoor heat exchanger is used as a condenser, and serves as a cooler in a cooling mode when the indoor heat exchanger is used as an evaporator.
