专注通风管道加工·排烟罩

通风设备压缩机正常范围：压缩机在夏季制冷状态下，排气温度比较高，不可用手触摸。制冷系统的排气温度不超过125℃左右。故障：排气温度超高原因，是压缩机的吸气温度超高，或是冷凝温度超高所造成，必须引起注意。上海风管加工排气温度过低，手摸排气管不烫手，这说明吸气温度特别低，压缩机可能湿行程运行或系统制冷剂特少情况下运行。压缩机湿行程运行容易损坏阀结构;制冷剂特少情况运行，会影响电动机的绕组散热，加速绝缘材料的老化。

Normal range of ventilation equipment compressor: When the compressor is in the cooling state in summer, the exhaust temperature is relatively high and cannot be touched by hand. The exhaust temperature of the refrigeration system shall not exceed around 125 ℃. Fault: The reason for the high exhaust temperature is due to the high suction temperature of the compressor or the high condensation temperature, which must be taken seriously. The exhaust temperature of Shanghai air duct processing is too low, and touching the exhaust pipe does not make it too hot. This indicates that the suction temperature is particularly low, and the compressor may run wet or with very little refrigerant in the system. The wet stroke operation of the compressor can easily damage the valve structure; Operating with very little refrigerant can affect the heat dissipation of the motor winding and accelerate the aging of insulation materials.

通风设备压缩机壳体温度正常范围：上机壳受吸入蒸气的影响，温度比较低，处在微热或稍凉范围，估计在30℃左右，在吸气管的周围局部机壳表面有结露水的可能。下机壳内电动机的发热量和被冷冻油带出的摩擦热量，上海风管加工厂主要由蒸气带出机壳。故障：机壳表面温度超过正常范围，主要是制冷系统的吸气温度过高。过高的热蒸气迸入压缩机，吸收机壳内热量后，使蒸气的温度更高，从而使机壳的温度上升。机壳表团温度低于正常范围，其原因是吸气温度太低。它对冷冻油和电动机绕组的冷却都有利，但制冷量有所下降。

The normal temperature range of the ventilation equipment compressor housing: The upper casing is affected by the inhalation of steam, and the temperature is relatively low, in a slightly hot or slightly cool range, estimated to be around 30 ℃. There is a possibility of condensation on the surface of the local casing around the suction pipe. The heat generated by the electric motor inside the lower casing and the frictional heat carried out by the refrigeration oil are mainly carried out of the casing by steam at the Shanghai air duct processing plant. Fault: The surface temperature of the casing exceeds the normal range, mainly due to the high suction temperature of the refrigeration system. Excessive hot steam rushes into the compressor, absorbing the heat inside the casing, causing the temperature of the steam to rise, thereby increasing the temperature of the casing. The temperature of the casing cluster is below the normal range, due to the low suction temperature. It is beneficial for the cooling of refrigeration oil and motor windings, but the cooling capacity has decreased.

排烟管道送风口设置在实际需要降温的地方，风口设计风量即使以其要降温地方所需的送风量，风口规格可根据风量与风口风速来确定，螺旋风管厂家送风口材质可采用塑料或铝合金等制品，出风口风咀形式可根据实际情况采用多种形式，选择锦煜空调专用风咀，风口喉部平均流速控制在3-6m/s，(采用4-5m/s的流速)。送风管的规格一般采用假定流速法设计，共板风管主风管保持在8-10m/s，支风管6-8m/s，＊末端风管保持4-6m/s，所设计的风管总体上要求既经济又能达到＊低的风阻和噪声，使锦煜冷风机的送风量尽量达到＊大值，风管弯曲半径一般不小于风管直径的两倍，以减少管通风阻力，送风管道的长度应根据不同型号的锦煜空调风压不同的特点进行设计。所设计的排烟管道尽量取直，避免不必要的拐弯和分支管，上海通风管道以减少管道局部阻力，从平面布置和经济角度上考虑，能不用风管的地方就不用风管，必须使用风管的地方尽量把风管设计短些，较长管道根据风量设计成多段不同规格的风管，采用变径管连接，变径管的设置不宜过多，一风管厂家般整根不超过四个，变径管长由“>2(D-d)”来确定，送风管道与冷风机主机出风口连接处应密封好;室外管道过长宜设计保温，室内管道一般不须保温

The smoke exhaust duct air supply outlet is set in the actual place that needs to be cooled. The designed air volume of the air outlet can be determined based on the air volume and the air speed of the outlet. The material of the spiral air duct manufacturer's air supply outlet can be plastic or aluminum alloy, and the form of the air outlet nozzle can be in various forms according to the actual situation. It is recommended to choose a dedicated air outlet for Jinyu air conditioning, with an average flow rate at the throat of the air outlet controlled at 3-6m/s, (It is recommended to use a flow rate of 4-5m/s). The specifications of the air supply duct are generally designed using the assumed flow rate method. The main air duct of the common plate air duct is kept at 8-10m/s, the branch air duct is kept at 6-8m/s, and the end air duct is kept at 4-6m/s. The designed air duct is generally required to be both economical and achieve low wind resistance and noise, so that the air supply volume of the Jinyu cold air fan can reach the maximum value possible. The bending radius of the air duct is generally not less than twice the diameter of the air duct to reduce the ventilation resistance of the duct, The length of the air supply duct should be designed according to the different characteristics of the air pressure of different models of Jinyu air conditioners. The designed smoke exhaust pipes should be as straight as possible to avoid unnecessary bends and branch pipes. Shanghai ventilation pipes should be designed to reduce local resistance of the pipes. From the perspective of layout and economy, air ducts should not be used in areas where air ducts are not necessary. Air ducts should be designed as short as possible in areas where air ducts must be used. Long pipes should be designed into multiple sections of different specifications of air ducts according to the air volume, and variable diameter pipes should be used for connection. The number of variable diameter pipes should not be too many, A manufacturer of air ducts generally does not exceed four in a single piece, and the length of variable diameter pipes is determined by ">2 (D-d)". The connection between the supply air duct and the outlet of the cold air fan should be sealed properly; Outdoor pipelines that are too long should be designed with insulation, while indoor pipelines generally do not require insulation
