Description

Technical Field

[0001] This application relates to a fluid temperature control system that uses a single compression module to supply two fluid temperature control modules in order to reduce energy consumption. Background Technology

[0002] In existing technologies, temperature and humidity control systems for gases and liquids, especially those used in applications requiring high-precision control, such as semiconductor manufacturing processes, precision instrument laboratories, biomedical equipment, or climate simulation environments, generally adopt a staged control approach to achieve the required accuracy and stability. That is, in terms of temperature control, a common method is to first cool the gas or liquid to a default reference point, and then heat it to bring it back to the required target temperature range, and vice versa. In some cases, the temperature is heated first and then cooled to reduce the initial instability of the system and ultimately achieve the goal of precise control.

[0003] However, according to existing technology design architectures, in order to ensure that different types of fluids (such as gases and liquids) can maintain high precision and stability under their independent control, a separate system architecture is often adopted. That is, the gas system and the liquid system each have independent cooling, heating, dehumidification, and humidification devices. Although this separate design performs well in terms of control precision, it comes with several potential problems. For example, since each system unit needs to perform heating and cooling operations independently, energy consumption is repeated, and energy recovery and reuse cannot be achieved, resulting in a large amount of energy waste in the long run. In addition, the system complexity is also increased, which places an additional burden on installation space and maintenance management.

[0004] In the process of adding and subtracting, although the desired temperature and humidity conditions can eventually be achieved, there will inevitably be stages in which the energy of the process is not fully utilized. For example, the heat energy released by the cooling system is not used at the heating end, or the water vapor removed during the dehumidification process is not used for subsequent humidification treatment. These intermediate resources or waste energy, which are often overlooked in existing technologies, become one of the bottlenecks in the overall system energy efficiency over time.

[0005] In summary, existing temperature control systems still have significant limitations in terms of integration, energy efficiency, and equipment size management. In particular, when facing multi-fluid mixing control requirements or high-density process environments, their complex design and excessive energy consumption still have room for further optimization and improvement.

[0006] In view of the problems of the prior art, this application provides a fluid temperature control system in which the compression circulation module is applied to both the liquid delivery module and the gas temperature control module. The energy generated by a single compression circulation module is used to exchange heat with the fluid, so as to simultaneously regulate the two fluids. Utility Model Content

[0040] See again Figure 1 And see Figure 2 , Figure 2 This is a schematic diagram of the electrical connection of an embodiment of this application. As shown in the figure, in this first embodiment, the compression cycle module 10 includes a compressor 12, a first heat exchanger 14, an expansion valve 16, and a second heat exchanger 18. The compressor 12 is used to compress and deliver a cooling medium C1. The first heat exchanger 14 is connected to the compressor 12 and receives the cooling medium C1 passing through the compressor 12. The first heat exchanger 14 also receives liquid L1, allowing the cooling medium C1 to exchange heat with the liquid L1 on one inner side of the first heat exchanger 14. The first heat exchanger 14 is used to regulate the flow of liquid L1.
