Maintenance of Cold and Hot Shock Test Chamber
The impact of temperature changes on refrigeration systems in compression condensing units
The temperature of the unit components has a normal temperature range, and exceeding this range is considered an abnormal state. The factors causing these abnormalities may be faults or incorrect adjustments, but their causes must be analyzed and dealt with or checked in a timely manner. These temperature points are difficult to measure with a thermometer and can only be estimated by hand feel to determine if they are normal.
The Influence of Exhaust Temperature on Maintenance and Repair of Shenzhen Constant Temperature and Humidity Test Chamber In summer, the exhaust temperature of the compressor is relatively high and cannot be touched by hand. According to national standards,R22The exhaust temperature of the refrigeration system should not exceed150 OCExceeding this temperature line is considered an abnormal condition. The reason for the excessively high exhaust temperature is due to the excessively high suction temperature of the compressor or the excessively high condensation temperature, which must be taken into account. The exhaust temperature is too low, and touching the exhaust pipe does not make it hot. This indicates that the suction temperature is particularly low, and the compressor may be operating in a wet stroke or with relatively little system working fluid. The wet stroke of the compressor can easily damage the valve structure; Running with very little refrigerant can affect the heat dissipation of the motor winding and accelerate the aging of the insulation material.
The impact of temperature changes in the casing of the Shenzhen constant temperature and humidity test chamber on the compressor and refrigeration system during maintenance and repair The temperature field on the outer surface of the fully enclosed reciprocating piston compressor casing can be divided into two parts:a.The upper shell is affected by the inhalation of vapor, and the temperature is relatively low, in the range of slightly hot or slightly cool, estimated to be30OCThere is a possibility of condensation on the surface of the casing around the suction pipe.B.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 the steam.
