Description

Technical Field

[0001] The utility model relates to the technical field of dual-channel cooling and heating, in particular to a dual-channel cooling and heating system. Background Art

[0002] Dual-channel cooling and heating is a technology that performs cooling and heating operations through two independent channels. This technology is often used in equipment or systems that require precise temperature control, such as precision instruments, electronic equipment, chemical reactors, etc. Since there are two independent channels, each channel can independently control the temperature, so more precise temperature control can be achieved. In cases where cooling and heating operations are required at the same time, the dual-channel system can use energy more efficiently because the two channels can work simultaneously instead of alternately. The dual-channel system can perform cooling and heating operations at the same time as needed, or only perform one of the operations, so it has higher flexibility.

[0003] The following problems exist: a common compressor can only cool down the temperature of one water tank, which means that the compressor can only provide cooling function for a single water tank. If multiple water tanks need to be cooled at the same time, multiple compressors are required, which not only increases the cost of using the compressor, but also reduces the cooling effect of the water tank.
