The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

As shown in fig. 1, the utility model provides a direct expansion unit, which comprises a shell 100 and a shielding component 2, wherein a fan 3 and a heat exchange component 1 are arranged in the shell 100, a heat exchange medium is arranged in the heat exchange component 1, the heat exchange component 1 can heat the heat exchange medium, the fan 3 can blow air to the heat exchange component 1 to exchange heat for the heat exchange component 1, the shielding component 2 is arranged above the shell 100, the shielding component 2 comprises a rain shielding plate and a solar panel fixedly connected with the rain shielding plate, the solar panel is used for heating the heat exchange medium, the solar panel is provided with an inlet end and an outlet end, the inlet end is communicated with the output end of the heat exchange component 1, the outlet end is communicated with the input end of the heat exchange component 1, and the heat exchange medium circularly flows in the heat exchange component 1 and the solar panel. The solar panel is arranged on the rain shield, solar energy can be directly utilized to assist in heating the heating medium, converted energy is directly utilized, loss in the process is avoided, and the conversion rate of the solar energy is higher than that of photovoltaic, so that the energy-saving effect is more ideal.

Specifically, the heat exchange assembly 1 comprises a heating device and a coil, wherein the heating device is communicated with the coil, and is used for heating the heat exchange medium and sending the heated heat exchange medium into the coil. The input end of the heating device is used as the input end of the heat exchange assembly 1, and the outlet of the coil is used as the output end of the heat exchange assembly 1. The cooled heat exchange medium is first discharged through the outlet of the coil along a path S3 (path S3 is shown with reference to fig. 1), and then enters the inlet end of the solar panel along a path S1 (path S1 is shown with reference to fig. 1) after passing through a transfer device (not shown). The transfer device can be a filter or a circulating pump, can be selected according to actual requirements, and can be arranged without the transfer device, and if the transfer device is not arranged, the path S1 is consistent with the path S3. The solar panel is provided with a black coating to assist in absorbing heat, while the solar panel is provided with micro-channels in which the heat exchange medium is initially heated and from the outlet end of the solar panel along a path S2 (path S2 is shown with reference to fig. 1) into the input end of the heating device, which heats the heat exchange medium to a preset temperature. Because the heat exchange medium is primarily heated before entering the heating device, the electric energy required by the heating device for heating the heat exchange medium to the preset temperature is reduced, thereby achieving the purpose of energy saving. The heat energy conversion rate of the solar panel can reach 50% or more, and the energy conversion rate is higher, so that the energy-saving effect is more ideal.

Further, the direct expansion unit is large in size, the corresponding required solar panels are large in area, the whole solar panels are high in cost, therefore, the production cost is further reduced, the number of the solar panels is multiple, such as 2, 3, 4, 5, 6, 7 or 8, and the like, the solar panels are uniformly arranged on the rain shield, and the whole large-area solar panels are decomposed into multiple small solar panels, so that the energy-saving effect is guaranteed, and meanwhile, the production cost is reduced.

Optionally, in order to avoid the situation that dust, fallen leaves and other sundries are accumulated above the shielding assembly 2 to reduce the solar energy utilization rate in the use process, the shape of the rain shield is set to be a sharp top shape, so that the situation that dust, fallen leaves and other sundries cannot be accumulated on the rain shield in a large amount in the use process is avoided, and the solar energy utilization rate is ensured.

Optionally, in order to further improve the solar energy utilization rate, the angle between the rain shield and the horizontal plane is adjustable. Specifically, one end of the weather shield is hinged with the housing 100, and the other end of the weather shield is connected with the housing 100 through an adjusting member, wherein the adjusting member is used for changing the angle between the weather shield and the horizontal plane. The angle of the solar panel is changed by changing the angle between the rain shield and the horizontal plane, so that the efficiency of converting solar energy into heat energy is further improved. The adjusting member may be a linear motor or an adjusting screw. For example, when the adjusting member is a linear motor, the linear motor is fixedly connected with the housing 100, an output shaft of the linear motor is connected with the other end of the weather shield, and the output shaft of the linear motor is connected with the weather shield in a sliding manner or hinged through a universal ball head, so that the angle between the weather shield and the horizontal plane can be adjusted and maintained by the output shaft of the linear motor. When the adjusting piece is arranged as a screw, the angle between the rain shielding plate and the horizontal plane can be adjusted and maintained, and the specific structure and the adjusting mode are not repeated in the prior art.

Still further, the shielding assembly 2 further comprises a photovoltaic panel and a battery, both of which are fixedly connected to the weather shield. The photovoltaic panel is electrically connected with a battery, and the battery is used for storing electric energy emitted by the photovoltaic panel. The solar panel, the photovoltaic panel and the battery are all arranged below the rain shield, so that dust accumulation is avoided. The weather shield is preferably made of acrylic materials, so that light transmittance is guaranteed, and the solar panel and the photovoltaic panel can work normally. The upper surface of the rain shield is laid with a heating wire which is electrically connected with the battery.
