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.

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.

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
