Embodiment Construction

[0012] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0013] See attached figure 1 As shown, the mixed liquid temperature adjustment method of the heat-changing cooling process, the heat-changing cooling cycle process is as follows: the cold fluid flows through the pipeline 3 from the constant-low temperature storage tank 1, the shut-off valve I2, and the circulation pump 4 to the heat exchanger 5. After the heat exchanger 5 completes the heat conversion, it flows back to the constant-low temperature storage tank 1 through the shut-off valve II6. In this circuit, a temperature measuring point and a flow measuring point are set at the inlet of the circulating pump 4. It is characterized in that : On the pipeline 3 between the cut-off valve I2 and the circulation pump 4, a three-way I7 is set to form a liquid return branch road, and the other end of the liquid return branch road i...

Abstract

The invention provides a liquid mixing and temperature adjusting method of a cooling process of heat transformation. According to the implementation mode of the method, a liquid return branch (7) is additionally arranged on an original circulation loop, so that part of liquid flows back to an inlet of a circulating pump (4) again after passing through a heat exchanger (5), the flow of returned cold liquid is adjusted through the opening degree of a flow regulating valve I (9) and a flow regulating valve II (11), thus different inlet temperatures of the different heat exchanger (5) are obtained, different outlet temperatures and temperature differences of the inlet temperatures and the outlet temperatures are obtained, adjustment of the heat exchange amount of the cold liquid is achieved finally, and requirements for engineering use are met.

Description

technical field [0001] The invention relates to a mixed liquid temperature regulating method in the cooling process of heat conversion, which belongs to the technical field of heat exchange. Background technique [0002] The working process of the heat exchanger: the hot and cold fluids exchange heat through the heat exchanger, and the heat absorbed by the cold fluid is always equal to the heat released by the hot fluid. In the application example model, the heat exchanger is used as an air cooler, that is to say, the tube heat exchanger is placed in the air duct for air circulation, the tubes are placed vertically, and the flowing hot air sweeps across multiple rows of tube bundles. Low-temperature brine flows in the tube with low inflow and high outflow. For hot air, if the flow velocity v is constant, the air flow rate per unit time will be constant. Engineering conditions There are multiple working conditions for the air inlet temperature, such as 20 degrees, 0 degrees...
