Abstract

The invention relates to a test air duct system for testing the heat exchange performance and dehumidifying / icing amount of an air heat exchanger, in particular to a test air duct system for testing the heat exchange performance and dehumidifying / icing amount of an air evaporator / condenser. The test air duct system includes a temperature-controlled evaporator, an electric heater, a wind speed sensor front damping rectifier, a wind speed sensor, a mass sensor, fans, an ultrasonic humidifier, a test evaporator / condenser front damping rectifier, a test evaporator / condenser front temperature sensor, a test evaporator / condenser front humidity sensor, a test evaporator / condenser, a soft connection of a circular air duct, an insulation can, a test evaporator / condenser rear damping rectifier, a test evaporator / condenser rear temperature sensor, a test evaporator / condenser rear humidity sensor, a circular air duct special heat insulation section, and a circular air duct ordinary heat insulation section. The system has the advantage that the front temperature, humidity and air speed of the test evaporator / condenser can be controlled accurately, and the heat exchange performance of evaporators / condensers of different types and sizes and the dehumidifying / icing amount of evaporators of different types and sizes can be tested. The frosting process and defrosting process of an evaporator can be observed and recorded.

Description

technical field [0001] The invention relates to an air duct system for testing the heat transfer performance and dehumidification / freezing capacity of an air heat exchanger, in particular to an air duct system for testing the heat transfer performance and dehumidification / freezing capacity of an air evaporator / condenser, which belongs to refrigeration technology field. Background technique [0002] The evaporator and condenser are two important components in the refrigeration system, and their performance directly affects the performance of the entire refrigeration system. However, in view of the characteristics of small heat transfer and low refrigerant flow rate of the evaporator and condenser of the refrigerator, the test environment of the evaporator / condenser, including the uniformity of wind speed, temperature and humidity, has a great influence on its performance test, and the high-precision The test results are more difficult. Therefore, it is essential to design a...
