Radiation terminal, temperature control circuit and testing system

Abstract

The invention relates to a radiation terminal, a temperature control circuit and a testing system. The radiation terminal comprises a cold radiation plate water tank, a water supply main pipe and a water return main pipe, wherein the water supply main pipe and the water return main pipe are arranged between the cold radiation plate water tank and a detected device. The radiation terminal also comprises a circulating water pipe and a flow valve; one end of the circulating water pipe is connected with the water supply main pipe through the flow valve; and the other end of the circulating water pipe is connected with the water return main pipe. According to the technical scheme provided by the invention, the circulating water pipe and the flow valve are arranged between the water supply mainpipe and the water return main pipe, entrance flow of liquid in the water return main pipe into the water supply main pipe is controlled according to a temperature of the liquid in the water supply main pipe and a temperature of the liquid in the water return main pipe, so that the aim of regulating a water inlet temperature is fulfilled, and thus, the water inlet temperature of the detected device keeps constant.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a radiation terminal, a temperature control circuit and a test system. Background technique [0002] Radiant air-conditioning technology is a relatively new technology in the air-conditioning system. Compared with the traditional air-conditioning system, the air-conditioning system using the radiant terminal device has a more uniform indoor temperature field distribution, less energy consumption, and can avoid traditional air-conditioning. The damage caused by refrigeration to human body function. [0003] At present, the construction of the laboratory for the ability test of the radiation terminal device is not very ideal. The common method to keep the temperature constant is to fully mix the water in the high and low water tanks, and at the same time conduct electric heating to keep the water temperature in the water tank constant. This method The structure of the sys...
