The elimination of the constant damp heat test chamber is an important task of the laboratory maintenance personnel. To completely eliminate the fault, it is necessary to understand the cause of the fault, and more importantly, to theoretically analyze and solve the fault, and have a certain professional theory. Knowledge, to master the method of troubleshooting. 1. The exhaust temperature of the constant damp heat test chamber compressor is too high: 1. The suction pressure is too low, the suction and exhaust pressure difference is too large (the cylinder compression ratio is large), the opening degree of the expansion valve is small, and the adjustment pressure is low; 2. The inhalation temperature is too high, that is, the inhalation superheat is large, the suction pipe is too long or the insulation effect is poor. 3. Insufficient cooling water or high water temperature 4. Excessive non-condensable gas (air) in the system 5. The condensing pressure is too high, and the corresponding condensing temperature is also high, causing the exhaust gas temperature to rise. 6, compressor cylinder or valve block failure Second, the condensing pressure and condensation temperature is too high: 1. The condenser cooling water is insufficient or the water temperature is too high. 2, the condenser is too dirty, too much scaling 3. Excessive non-condensable gas (air) in the system 4, too much refrigerant in the system 5. The heat transfer area of ​​the condenser is too small. Third, the constant damp heat test chamber compressor oil temperature is too high: 1. The intake and exhaust temperatures of the compressor are too high. 2, the lubricant is too dirty or the oil is too bad 3, the compressor parts are seriously worn 4. The exhaust pressure of the constant damp heat test chamber compressor is too high: 1. Excessive non-condensable gas (air) in the system 2. Insufficient cooling water or high water temperature 3, the condenser is too dirty, too much scaling 4, too much refrigerant in the system Cast iron griidles offer a flat cooking surface with slightly raised edges to keep oil, batter, and other ingredients neatly contained. They are the perfect kitchen tool for frying up a hearty breakfast of eggs, sausage, bacon, and pancakes. Use them to make classic grilled sanwiches and even for cooking pizzas.
