[0004] The purpose of the present invention is to propose a performance test system and test method of an air-cooled evaporation composite cross-flow closed cooling tower for the existing actual operation of the composite tower that cannot realize the influence of operating parameters and structural characteristics on its performance. To overcome the difficulties in measuring the operational performance of the actual air-cooled and evaporative compound tower under variable working conditions and variable structures, by controlling the air intake parameters, adjusting the air supply volume and the position of the air supply outlet, adjusting the water intake area, adjusting the spray water volume, and replacing the light pipe for heat exchange The relative position of the heat exchanger, packing and finned tube heat exchanger can realize the test of the influence of different operating parameters and structural characteristics on the performance of the composite type, and realize the simulation test of a test system with multiple working conditions, multiple parameters and multiple structures.

Abstract

An air-cooled evaporative composite cross-flow closed cooling tower performance testing system and testing method belong to the technical field of cooling water circulation. It is difficult to measure the operation performance of variable working conditions and variable structures. By controlling the air inlet parameters, adjusting the air supply volume and the position of the air supply port, adjusting the water inlet area, adjusting the spray water volume and replacing the light tube heat exchanger, packing and finned tube replacement The relative position of the heater can realize the test of the influence of different operating parameters and structural characteristics on the performance of the composite type, and realize the simulation test of a set of test systems with multiple operating conditions, multiple parameters and multiple structures.

Description

technical field [0001] The invention belongs to the technical field of cooling water circulation, and relates to a cooling tower performance testing system and testing method, in particular to an air-cooled evaporation composite cross-flow closed cooling tower performance testing system and testing method. Background technique [0002] As an important heat dissipation device to reduce the temperature of cooling water, cooling towers are widely used in civil air conditioners and industrial fields such as metallurgy, chemical industry, electric power, and textile. As a new type of cooling and heat exchange equipment proposed in recent years, the air-cooled evaporative composite cross-flow closed cooling tower adopts the double cooling method of air cooling + evaporative heat absorption, and is a closed cycle, which has the advantages of high cooling heat exchange efficiency and low heat exchange rate. It is a high-efficiency, energy-saving and water-saving cooling and heat exc...
