3results about How to "Precise water temperature control" patented technology

This utility model discloses a water temperature control device for Litopenaeus vannamei (whiteleg shrimp) farming, comprising a heater and a cooler. Both the heater and cooler have inlet pipes mounted on their sides, connected by a T-junction. A delivery pump is mounted on the side of the T-junction, and a dispersion component for water dispersion is mounted on the side of the delivery pump furthest from the T-junction. This utility model's heater and cooler reliably provide cold and hot water, the delivery pump ensures efficient water delivery, the dispersion device effectively achieves uniform water dispersion, and the temperature monitoring and control system ensures precise water temperature control. This rational structural design improves the reliability and durability of the equipment, reduces equipment failures, lowers maintenance costs, extends the equipment's service life, and provides long-term stable water temperature control for Litopenaeus vannamei (whiteleg shrimp) farming.

The utility model provides a constant-temperature dual-mode water heater. The constant-temperature dual-mode water heater comprises a preheating water storage assembly, a waterway control assembly and a constant-temperature control assembly. The preheating water storage assembly comprises a water storage part and a heating part, and the water storage part is provided with a water outlet end and a water inlet end; the water path control assembly comprises a water path constant-temperature control part and a water path pipeline part, the water path pipeline part comprises a first pipeline, a second pipeline, a third pipeline, a fourth pipeline and a water mixing pipeline, and the water path constant-temperature control part is arranged on the water mixing pipeline; one end of the first pipeline, one end of the third pipeline and one end of the fourth pipeline are respectively communicated with the water mixing pipeline; the other end of the first pipeline communicates with a water source; one end of the second pipeline communicates with the first pipeline, and the other end communicates with the water inlet end; the other end of the third pipeline is communicated with the water outlet end; the other end of the fourth pipeline communicates with the constant-temperature control assembly. Through two times of temperature control in sequence, hot water with the temperature set by a user can be accurately output, water temperature control is accurate, the use experience of the user is improved, and meanwhile the water conveying pipeline is compact in layout and small in occupied space.

The utility model discloses a PCM application engineering parameter test experimental device which comprises a host, a water temperature control mechanism is arranged in the host, the water temperature control mechanism comprises a circulating water pool and two PCM cold storage water tanks, a plurality of ice plates are assembled in the PCM cold storage water tanks, and spoilers are assembled in inner cavities of the PCM cold storage water tanks. The side wall of the circulating water pool is fixedly connected with a water outlet pipe and a water inlet pipe, the other end of the water inlet pipe is fixedly connected with a three-way pipe, a butt joint pipe is fixedly connected between the second end of the three-way pipe and one PCM cold storage water tank, and a flow guide pipe is connected between the two PCM cold storage water tanks. According to the utility model, the water quality cleanliness is increased, the PCM can be more fully contacted with water, the heat transfer is smoother, the water temperature can be more quickly reduced or increased, and the PCM detection reliability is improved.
