Integrated performance test method for vaporization cooling in various heat exchange models and modes

Abstract

The invention relates to an integrative performance test method for vaporizing and cooling different heat exchange models and modes, comprising the following steps that: 1. a multifunctional test for testing the performance of the vaporizing and cooling the heat exchange module is prepared; 2. the heat exchange performances of the two models of the heat source dissipation inside the heat exchange module and the heat source dissipation outside the heat exchange module are tested; 3. under the two models, the heat exchange performance of the crosscurrent, the reverse current and the fair current modes of the vapor flow direction are tested. The invention adopts one set of the wind source, the water source, the electroheat source and the test system, takes a small wind-cone as a body, can test the heat radiation performance of hot water in the stuffing under the external heat source under various modes of the crosscurrent, the reverse current and the fair current of the vapor by simple transformation and can test the heat source cooling performance under the internal heat source. The tests basically include the main heat performance tests of an open type cooling tower and a closed type cooling tower as well as the outside of the vapor cooling pipe (condensing pipe). Moreover, the method is simple and feasible, the test range is wide and the comprehensiveness is strong.

Description

technical field

[0001] The invention relates to an integrated test method, in particular to an integrated performance test method for studying different heat transfer models and modes of evaporative cooling. Background technique

[0002] Cooling towers and evaporative cooling (condensers) are general-purpose equipment widely used in air conditioning and industrial heat cycles, and are closely related to energy and water conservation that urgently need to be solved in national economic and social development.

[0003] The chiller that cools the circulating water is usually called a cooling tower. The principle of the open cooling tower is to directly convect heat between the cooled water and the air and evaporatively cool it. The evaporative cooling (condenser) allows the refrigerant to flow in the tube, sprays auxiliary cooling water outside the tube, and then the auxiliary cooling water convects heat with the air and evaporatively cools it. When the refrigerant to be coole...
