Multifunctional heat and humidity characteristic simultaneous test bench

Abstract

The invention belongs to the technical field of heating ventilation and air conditioning experiments and discloses a multifunctional heat and humidity characteristic simultaneous test bench. The coldbox of the test bench is filled with cold air with constant temperature and humidity, and a cold box air handling room is connected with the cold box for handling air in the space; a protective hot box is filled with hot air with constant temperature and humidity, and a protective hot box air handling room is connected with the protective hot box for processing air in the space; a measuring deviceis arranged between the cold box and the protective hot box and is divided to a measuring area and a sampling area for testing heat transfer and moisture transfer; a measuring box is arranged insidethe protective hot box and is connected with the measuring device; and an adjusting device is used for adjusting the temperature and the humidity of the air in the cold box air handling room, the protective hot box air handling room and the measuring box. The test bench in the invention can realize simultaneous heat and humidity characteristic test, electroosmosis characteristic test and heat exchanger performance test, and has the advantages of compact structure and multiple functions.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air-conditioning experiments, and more specifically relates to a multifunctional synchronous test bench for heat and humidity characteristics. Background technique [0002] In the field of HVAC, the performance of HVAC equipment itself and the thermal performance of the building envelope closely related to it have a great impact on energy consumption. In order to reduce the energy consumption of heating and air conditioning, it is necessary to optimize these The performance of equipment and structures is tested and optimized. [0003] In colleges and enterprises, experimental systems with different testing purposes have been successively developed, such as enthalpy difference chambers, constant temperature and humidity chambers, heat exchanger performance test systems and building envelope performance test platforms, etc., but due to the Due to the characteristics of the equipmen...
