摘要： A method for predicting surge in a compressor is provided, which is applicable to a cooling apparatus equipped with a centrifugal compressor. A set of highest outlet pressure values is obtained by a performance test performed on the centrifugal compressor. A coolant flow rate value and an opening percentage value of inlet guide vanes of the centrifugal compressor are measured. An outlet pressure value of the centrifugal compressor is calculated with an equation using the measured coolant flow rate value and the measured opening percentage value. The outlet pressure value is compared with one of the highest outlet pressure values corresponding to the measured opening percentage value, and if the outlet pressure value is larger than or equal to the highest corresponding outlet pressure value, it confirms imminent surge in the centrifugal compressor, so as to provide a basis of preparation for surge elimination.

摘要： A spray type heat-exchanging unit includes a main body; a distributive refrigerant spray module located in an upper part of the main body and having an extended distributor and a refrigerant spray surface; and a plurality of heat exchange tubes provided in the main body below the distributive refrigerant spray module. A liquid refrigerant is guided into the extended distributor to drip onto the refrigerant spray surface, and then uniformly sprayed onto the heat exchange tubes. Gaseous refrigerant produced by evaporation in heat exchange in the main body is recovered via a top opening of the main body, making the mechanical refrigerating apparatus more efficient than a refrigerating apparatus adopting a flooded evaporator, and minimizing the refrigerant charge amount and material cost required by the heat-exchanging unit.

摘要： A spray type heat exchange device includes a spray unit, a first group set of heat transfer tubes, at least a distributing unit and a second group set of heat transfer tubes. The distributing unit redistributes the remaining liquid refrigerant that is sprayed out from the spray unit and flowed through the first group set of heat transfer tubes, and the remaining liquid refrigerant is dropped downwardly to the second group set of heat transfer tubes. By this disclosed method, the inner space of the heat exchange device could be fully utilized to configure and accommodate more heat transfer tubes therein.

摘要： A refrigerant floating expansion apparatus including a main body, a standpipe, a float element and a separation element is provided. The main body includes a base plate and a pipe-shaped housing. The standpipe fixed on the base plate has a second pipe opening and a third pipe opening. The pipe wall of the standpipe has at least an opening near the second pipe opening. The float element surrounds the standpipe for controlling a fluid-passing area of the opening. The separation element surrounding the float element is disposed on the base plate and forms an inner path with the pipe-shaped housing. The separation element has several fluid passageways near the base plate. A high-pressure fluid entering the main body is guided to pass through the fluid passageways to move the float element for controlling the fluid-passing area of the opening. Then, the high-pressure fluid is transferred to a low-pressure fluid.
