Description
技术领域technical field
本实用新型涉及一种制冷装置，尤其涉及一种应用于电气室的低能耗制冷装置。The utility model relates to a refrigeration device, in particular to a low-energy consumption refrigeration device applied to an electrical room.
背景技术Background technique
电气室内主要产热设备为配电柜，为了保证配电柜的正常运行，需使其温度保持在较低值，现阶段的普遍做法为在配电柜内设置小型风机，通过风机将配电柜产生的热量通过配电柜上部的百叶窗排出，但因而会造成电气室室内的温度较高，夏季时甚至可达40℃以上，严重影响检修和操作人员的工作环境。The main heat-generating equipment in the electrical room is the power distribution cabinet. In order to ensure the normal operation of the power distribution cabinet, its temperature needs to be kept at a low value. The common practice at this stage is to install a small fan in the power distribution cabinet, and the power distribution cabinet will be distributed through the fan. The heat generated by the cabinet is discharged through the louvers on the upper part of the distribution cabinet, but this will cause the temperature in the electrical room to be high, even reaching above 40°C in summer, which seriously affects the working environment of maintenance and operators.
为了改善电气室内部环境，通常会在电气室内放置制冷空调设备，如果空调选型及布置合理，可有效改善电气室内部环境，但耗电量较大，并占用电气室内部空间。或者在电气室的外壁设置轴流风机将室内热量排至室外，并采用自然回风或另设风机箱将洁净空气送入室内，耗电量及占用内部空间较小，但制冷效果较差。In order to improve the internal environment of the electrical room, refrigeration and air conditioning equipment is usually placed in the electrical room. If the air conditioner is selected and arranged reasonably, it can effectively improve the internal environment of the electrical room, but it consumes a lot of power and takes up space inside the electrical room. Or install an axial flow fan on the outer wall of the electrical room to discharge indoor heat to the outside, and use natural return air or an additional fan box to send clean air into the room, which consumes less power and occupies less internal space, but the cooling effect is poor.
