Description

TECHNICAL FIELD

[0002] The cold and hot water chilling unit, also known as a cold and hot unit, is a high-efficiency device integrating refrigeration and heating functions, and its core components include a compressor, an expansion valve, a condenser, an evaporator, and refrigerant, etc. These components work together to enable the unit to generate cold water and hot water simultaneously, providing a constant temperature and humidity environment for buildings and industrial facilities. In the refrigeration cycle, the compressor compresses the refrigerant into a liquid state and sends it to the evaporator, where the liquid refrigerant rapidly evaporates and absorbs a large amount of heat, thereby reducing the temperature of the chilled water and achieving the refrigeration effect. Subsequently, the gaseous refrigerant is sucked back into the compressor to start a new cycle. In heating mode, the unit utilizes the waste heat generated in the refrigeration cycle or other heat sources to transfer heat to the hot water circulation system through a heat exchanger, thereby providing hot water.

[0003] The existing cold and hot water chilling unit requires water pipes to connect the equipment and external devices. However, during long-term use, the pipes may leak due to material aging, water pressure fluctuations, corrosion and erosion, thermal expansion and contraction caused by temperature changes, external physical damage, or improper maintenance. These leaks not only waste water resources but also affect system efficiency, reduce refrigeration and heating effects, and even cause potential damage to equipment, such as short circuits and accelerated corrosion.
