Description

Technical Field

[0001] This utility model relates to the field of integrated cooling and heating temperature control technology, specifically an integrated cooling and heating machine. Background Technology

[0002] Integrated cooling and heating units, as integrated temperature control devices that combine cooling and heating functions, achieve precise temperature regulation through a media circulation system and are widely used in industrial manufacturing, laboratory temperature control, and other scenarios. Their core advantage lies in fulfilling the need for alternating cooling and heating through a single system, avoiding the energy loss and response delays caused by frequent switching of working fluid flow in traditional split-type devices. However, existing integrated cooling and heating units generally suffer from structural design flaws: the cooling and heating modules often adopt a parallel layout, resulting in redundant and complex internal piping, long media flow paths, high resistance, and significant thermal inertia, making it difficult to meet the high-precision, fast-response process requirements.

The circulating medium pipeline delivers the circulating medium to the temperature control equipment or the object to be temperature controlled. During the delivery process, the medium exchanges heat with the circulating refrigeration pipeline for cooling or with the heating component for heating, depending on actual needs.
