Abstract

The invention discloses an improved temperature control system and method. According to the temperature control system, a fast cooling path is newly increased in a traditional temperature increasing and decreasing temperature control pipeline; during fast cooling, a refrigerating unit needs to run with a maximum load so as to lower the laboratory temperature at the fastest cooling speed; an external circulation refrigeration pump directly pumps a refrigerating medium cooled by the refrigerating unit into the laboratory; and a refrigerant outflown from a water outlet of a fluid line in the laboratory goes directly into the refrigerating unit instead of a refrigerating tank, so that a flow path and a cooling load of the refrigerating medium in the refrigeration tank are reduced.

Description

technical field [0001] The invention belongs to the technical field of weather modification, and in particular relates to an improved temperature control system and method. Background technique [0002] The cloud chamber is the basic equipment for cloud physics and weather modification research. It can simulate the key links of natural clouds and precipitation, including hygroscopic growth, activation, and condensation growth of aerosol particles. Temperature control is required during the cloud chamber test. At present, the temperature control system of most cloud chambers in China is generally divided into a heating path and a cooling path. According to the experimental needs, the corresponding pipeline valves are opened, and the cooling rate is controlled by adjusting the fluid flow and pressure in the pipeline. However, in order to expand the functionality of the laboratory and improve the feasibility of the experiment, the cloud and fog laboratory needs to achieve rapid...
