Heat exchange system and central air conditioning system

Abstract

The invention relates to a heat exchange system and a central air conditioning system. The heat exchange system comprises a hot water conveying unit, a hot water supply pipeline and a heat disc for performing heat exchange with air as well as a cold water conveying unit, a cold water supply pipeline and a cold disc for exchanging heat with air, and a water supply communicating pipeline, wherein an inlet of the heat disc communicates with the hot water conveying unit through the hot water supply pipeline; a first valve is arranged on the hot water supply pipeline; an inlet of the cold disc communicates with the cold water conveying unit through a cold water supply pipeline; a third valve is arranged on the cold water supply pipeline; the first end of the water supply communicating pipeline communicates with the hot water supply pipeline and is positioned behind the first valve; the second end of the water supply communicating pipeline communicates with the cold water supply pipeline and is positioned behind the third valve; and a fifth valve is arranged on the water supply communicating pipeline. The heat exchange system can effectively improve refrigerating or heating ability, so that precise control on environment temperature can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of central air-conditioning, and in particular, to a heat exchange system and a central air-conditioning system. Background technique [0002] In the production process of glass for display terminals, the precision of temperature control directly determines the quality of the product. Especially the temperature in areas such as glass tunnels and glass forming is a top priority. Temperature control is the most critical factor in the glass production line for display terminals. The stability of each control temperature directly determines the quality of the product; especially the temperature parameters in key areas play a decisive role in the flow control of the glass channel and the adjustment of glass quality. role. In short, stable and controlled ambient temperature is the basis for stable product quality. [0003] In order to ensure that the entire production line of terminal display glass has...

Problems solved by technology

However, various interference factors such as seasonal changes, temperature difference between day and night, and equipment aging have seriously affected the cooling or heating capacity of the central air-conditioning system, which in turn affects the control accuracy of the central air-conditioning system on the ambient temperature, resulting in the inability to obtain the ambient temperature in the production workshop. Guarantee that once the on-site temperature in key areas such as aisles and molding is uncontrolled, it will seriously affect the stability of the entire glass production line, resulting in process fluctuations in the production line or product waste
