Constant temperature box system and its control method

Abstract

The invention discloses a constant temperature box control system, which includes a central control system, a constant temperature box system and a medium pipeline. The central control system is connected to the constant temperature box system through the medium pipeline. The constant temperature box system includes at least two constant temperature boxes, wherein: It is used to provide temperature-regulating medium to the incubator system; the incubator system accepts the temperature-regulating medium and realizes temperature regulation; the medium pipeline is used to transport the temperature-regulating medium. This incubator control system concentrates the refrigeration system in the central control system, realizes centralized energy supply and distributed temperature and humidity control, thereby avoiding frequent start and stop of the individual incubator, reducing energy consumption and improving refrigeration efficiency. Efficiency, the volume of the terminal incubator is greatly reduced due to the reduction of refrigeration equipment, which is convenient for centralized arrangement, further realizes unified discharge, and reduces the layout of indoor room temperature air conditioners.

Description

technical field [0001] The invention relates to a thermostat system and a control method thereof, in particular to a centralized thermostat system and a control method thereof. Background technique [0002] The key components in many technical fields of batteries need to control their temperature when performing performance tests on batteries, battery modules and battery systems. Large battery testing laboratories require a large number of incubators. Although there are differences in the performance indicators of these incubators, their The working principle is to adopt the method of electric heating and electric cooling to realize the temperature control in the incubator through control. Each incubator includes a compressor, resistance wire heating and temperature control system.

[0002] The key components in many technical fields of batteries need to control their temperature when performing performance tests on batteries, battery modules and battery systems. Large battery testing laboratories require a large number of incubators. Although there are differences in the performance indicators of these incubators, their The working principle is to adopt the method of electric heating and electric cooling to realize the temperature control in the incubator through control. Each incubator includes a compressor, resistance wire heating and temperature control system. Because the single incubator contains The above-mentioned components are bulky and take up a lot of space; in large-scale laboratories, multiple incubators are required to run at the same time, which consumes a lot of energy; the main means of heating a single incubator is an electric heating wire, and the additional heat generated when there is a constant temperature or cooling demand is directly discharged to the In the environment, energy consumption is wasted. Ordinary constant temperature box compressors are fixed frequency. When a certain temperature point needs constant temperature control, it is necessary to start the heating wire and compressor at the same time to offset the excess cooling capacity or heating capacity to maintain the temperature. Balance, which further leads to increased energy consumption; the internal layout of the incubator with different power levels is not well planned, and the use environment cannot be improved
